QTH – Digital Modes

Posted on January 8, 2023 by webmaster@hamradio.knipmeyer.co.uk

Whilst no POTA Activations myself I did enjoy making some POTA Hunter contacts this weekend, albeit on FT8.

Its nice to be part of something, even when I cant get out the shack to do PoTA activations, I appreciate those guys who do go out and operate from the parks !

G7WKX@G-0620 – Wirral and Thurstaston Country Park

I noticed I was having some issues with the IC7300, i.e. it kept on rebooting ! With some analysis I was able to find I had somehow knocked the power supply output voltage to 9v ! It was quite something to be making contacts at all, but rest assured 13.8V was soon restored and the 50W available to me soon back in use.

Having been playing/monitoring with QSSTV on Linux, I rebooted my Ham PC and went into Windows to use MSSTV – its been a while since I used it, but I must say I find the interface much more ‘friendly’ than QSSTV. I made really good QSO’s via SSTV.

First EA3AUW, a very nice QSO into Spain, with great signal reports. Looks like a slight typo in my callsign, but I was glad to make the contact and have the QSO on 14.2300. SSTV gets very busy on weekends, so getting clear images and completing was great.

I had another great QSO with IU5KZF on 20M – I was really getting thu with my 50W from the QTH, the RX pics was a true P5/595 for the best part. I think the USB Audio codec drivers under Windows are slightly better than under Linux/Ubuntu – I’ve not really looked under the hood, but I seem to get better pictures from MMSSTV than I do from QSSTV. Still, I was glad to make two really great SSTV QSO’s from the QTH.

Elsewhere I was prepping for my next PoTA – Whilst I find the iPad and SDR Control to be amazingly easy to use and setup, I have used my laptop and IC705 out in the field before, having made a SSTV contact for PoTA (Upton Heath Park), so I thought it a good time to check the laptop and IC705 again. My main ‘niggle’ with the laptop was having to the USB Cable. I installed WFView on the laptop, along with VBAudio Cable and the Serial Com Port emulator – whilst I could connected and hear audio from the laptop, the laptop is just old I think it cannot do all the things I need it to do via WFView – I reinstated the USB Cable and went ‘native’ and everything (SSTV, FT8, FT4) started working perfectly again.

IC705 and Laptop running WSJTX for WSPR via 6BTV on 40M

I have now setup my IC705 to hang off my 6BTV doing WSPR on the laptop, I’m running 1W into 40M to do the propergation reports, and its working really well, so I know for my next PoTA I can use the laptop and do/try SSTV again !

I twasn’to be disappointed with how well the IC705 and WSJT~X was doing on 40M and 1W of power, in no less than 12 hours the 6BTV and IC705 had reached all over the planet, needless to say, I was very happy with that the IC705 and 6BTV was working correctly and getting some action, rather than being sat in a bag !

I’m now looking forward to G5TM’s 145 Alive Event on 2M – a way to have simplex contacts via 2M. G5TM has put allot of work coordinating the event and G5STU “should” be within my reach from IO90BS. I’m sure many of us know G5TM excellent youtube channel, but incase you’ve not been introduced, hers the 145 Alive Event posting.

G5TM 2M 145 Alive Event

So I’m almost making the postings back on a weekly basis and there is enough in the shack at least to make something interesting to talk about, hopefully I can keep new blog postings going reguarly.

Until then 73

G-0112 New Forest – First POTA of 2023

Posted on January 3, 2023 by webmaster@hamradio.knipmeyer.co.uk

Happy New year to you all who follow the blog ! Apologies for the absence of postings, hopefully I’ll keep them a little more regular, at least with doing a PoTA once a month.

Having watched several of my youtube hamradio favourites I was really inspired to get out with my radio and enjoy it. With amazingly good weather, I headed out to the New Forest, specifically to Bratley View.

I was quick to get the Alexloop Hampack antenna setup quickly and the IC705 tuned into 17m quickly. Using the excellent SDR Control on the IPad it wasn’t long before the contacts on FT8 started coming in.

In under 30 minutes I had made 13 FT8 QSO’s on 17M. I then tried FT4 on 20M, I could pick up the signals ok, but wasn’t haven’t much luck in making contacts.

I headed down the band to FT8 which was busy as ever ! I had no problem getting out and making contacts there.

With well in excess of my required 10 contacts for me to activate the park and with my lunch finished, I headed back to home to enjoy the rest of the day with XYL.

Lunch was boiled egg and sausages – but I had forgotten my pen !

I wasn’t able to locate my pen, so couldn’t log manually, which I usually do just incase something happens to the IPad.

As I was totally dependent on the IPad for logging, I exported and ADIF file. Since I last done POTA there is now an option to upload your own log files, so I set about checking out how to do that. A great video really helped me along.

Tutorial on how to use the POTA upload

The log export from SDR Control is great, but requires a bit of ‘munging’ to get into PoTA format. I found a script ruby-pota-csv-to-adif available here which made getting the file uploaded right first time.

With the upload complete, the following morning most of the processing was complete, I was pleased to see other PoTA Hunters in the log.

EC7AKV & SP8QC contacts amongst many others!

It was great to get back out on the radio and enjoy the simplicity of FT8 – I’m hoping to get some practice and try out using Telephony QSO’s via SDR Control, or just using the microphone, it felt great to be back out with the radio and enjoying it again!

Hopefully I’l have more progress on other radio fronts as well, but until next time, 73!

Finding some time for radio !

Posted on December 7, 2022 by webmaster@hamradio.knipmeyer.co.uk

Its been a busy time, and it really still is – but having plenty of work is a good thing, sadly that leaves little time for ‘hobbies’ – as such a recent hardware failure caused me to migrate my existing Windows PC to a micro PC, I’ve kept Windows on it, but have also installed Ubuntu on it. I’m mostly enjoying FT8, FT4 and WSPR, getting a good range of signal reports on 2M and 80M and automated reports via WSPR to populate the webtechnologies site.

Playing with FT8 on the IC9700 and IC7300

The work I started in September on my dual-band rotator has come to a halt, with the shorter days and busy weekends, I’ve not had the time to investigate a high SWR issue. I suspect water ingress on the splitter at the mast-head, but haven’t got around to even unplugging it ! A recent holiday saw it took me well over a week to just reconnect my radios – I did enjoy the holiday, having enjoyed a wonderful long weekend in Switzerland.

The snow in October atop Rochers de Naye near Montreux

I’m slowly working on getting apps on Ubuntu – my other favourite mode being SSTV. I have been receiving images via QSSTV which automatically get upload to the “Live” SSTV Page.

QSSTV appears to have many more features than MMSSTV, no doubt it will take me some time to learn them all. I do like how it has date-stamped and the frequency received of the pictures, I just have to learn how to use the template editor to create my own pictures.

Well, life never stops here and time is very hard to come by these days, but I’ll try updating the blog a little more often.

73 Alan.

A relaxing walk along the river Stour with 2M SSTV Testing

Posted on September 11, 2022 by webmaster@hamradio.knipmeyer.co.uk

With the recent wind and rain, with the rain being very much needed given the recent near-tropical climate, the good weather presented a nice opportunity to take a stroll along the River Stour.

I’ve recently received another VC-H1 via ebay – this one complete with its cable and in very good condition. The cable fits a Baofeng UV5R and with the THD7 not having a battery suitable for mobile operation, seemed a perfect time to combine a nice walk and testing out the THD7 with the UV5R.

I started off on my usual walk to the local park, which has a nice path to take me to the Stour, there is a bit of road involved, but it was a good place to start testing the UV5R. I had setup FTP auto upload to the 2M SSTV section, so was able to see via the Website – of course I did wait a little just incase someone replied !

First transmission received back at the QTH

The UV5R max power is 5W, so I left it at that. I used normal FM (there is a narrow option) but I believe SSTV is fine as FM. The 9700 receives and sends in FM-Digital mode.

I could at least see the UV5R was working fine, as it should be at this relative short distance (less than 1 mile), but nether the less it was good to see al the systems working well together, i.e. RX via Radio, MMSSTV decode, FTP Upload and available via the website.

I headed a little further down towards where I would usually turn right and start the leg ward journey back home, in this case I carried on towards the Stour River via the Kingfisher Barn visitor centre, which has lovely wood carvings all along the path towards the river.

Having my mobile phone with me and it being a little less busy I was able to generate the tone to test the RX of the UV-5R, I sent the tone and transmitted, the received picture worked really well, with a nice carving of an owl received, which was then re-transmitted back and well received my the UV5R. I’m running 50W into a Diamond X50 back home, so it should come as no suprise that I could receive the picture is relatively short distance, but still glad all the systems worked well.

I kept walking towards the river, its slightly lower and certianly well below the height of the base of my antenna, but with being 30ft up, is still within line of sight. My pictures were well recived by the replay SSTV station and Sweety was having an equally good time, playing with other dogs and enjoying the cooler air.

Given the VC-H1 is quite old and transmits in Robot72 mode, I was quite impressed with the colour quality of the camera. I will need to do some research as to what CCD, or other device, it is using for the capture, the colours in the kingfisher memorial seat are quite true to life and with only Robot72 mode being used is a pretty good rendition. We can see the difference between a modern camera on an Iphone compared to the VC-H1 Robot72, but again being able to go mobile and do SSTV is still quite a novelty for me and am just glad it works!

Having neared Cherry Tree park it was time to head back home, we had walk quite a distance and the walk back home was along the busy roads, so no chance to take pictures there whilst walking Sweety. I was happy that the UV5R at over a mile way gave P5/595 picture results on 5W of power, so I could have a true portable SSTV experience and I felt really great from the lovely walk along the river.

I shall be sure to head back again as with autumn approaching, the scenery will get ever so radiant.

G-0407 Lodmoor Country Park POTA

Posted on June 27, 2022 by webmaster@hamradio.knipmeyer.co.uk

After a few weeks break of regular PoTA Activations, I was very excited to go out for my planned activation at Lodmoor Country Park near Weymouth.

I had completed my prep the evening before, checking that my batteries and accessories were all packed into the Alex loopham pack bag. In the morning I found that XYL Monica had even made me a pack lunch for my day out, which was much needed later in the day. An early start got me out with walking my dog Sweety at 5AM just as the sun came up, I then headed off to Weymouth, APRS beacon sending out packets as I did so, my full route wasnt covered today which seemed unusual, I did hear APRS packets on arrival in Weymouth.

APRS Recetion dropped off around Bere Regus

I chose to go to Beach Car Park, as this was situated conveniently near to the park facilities, its always useful to have a WC available, also the park itself look great and venturing beyond the comfort of the Bongo to get into the park would be nice.

The Beach Car Park is open 24/7, and even free between 18:00 and 08:00, although the signage says ‘no overnight sleeping’. Interestingly I noticed that Motorhomes are banned outright (probably for this reason), and where as my Mazda Bongo is classified as a Campervan would still be limited to a ‘4 hour’ max visit – noticed this of course after I had paid £10 for the full day, and whilst I think during the less busy seasons its unlikely to be enforced, I can imagine during peak times its something to be of mindful of.

Before settling into the Bongo and setting up, I popped to the WC, even at this early hour the facilities are open and clean and tidy, nice to see. The park had great maps to help navigate around. There is alot to do here for a family, such as Sealife centre, gokarts, mini-golf, pitch and putt and Sandwolrd – maybe its the kind of place where the youngsters could be enjoy the activities whilst allowing others to be operating the radio, win all round !

Once back in the Bongo I was quickly on the air thanks to the fantastic Alex Loop Antenna – whilst I have other antennas, the ease and speed in which I can get this setup really makes it hard to use the alternatives. Using the bikestand as a support which I can drive the bongo onto ensures that the wind doesnt get the better of it as well !

With the magloop just out the door and feedline thru the front window, I could get the SWR pretty much always under 1.5 to 1:1 – 20m was alive with contesters – even FT8 was super busy – the excellent SDR Control really helped – I cant say how good this application is, I am getting more out of it every single time I use it, the ease of logging and connection to the IC705 via Wifi is excellent. FT8 got very busy, so remembering I had FT4 available also, headed up the band slightly and enjoyed a rapid sucsession of QSO’s. Within one hour I was very close to having enough QSOs to activate the park.

I also log manually just to ensure I have a backup, I found today that jumping between bands was getting easier – I tuned 1:1 on 17m in just one go, and by now with a great collection of data mode QSO’s under my belt, felt it was time for some telephony/SSB action.

I piggy backed on the back of the contest, it was great running QRP portable and even the contesters were happy to receive a mobile station, some even going beyond the usual contest rubber stamp asking my about my setup ! I really enjoyed that and a method I will use in the future (I actually was inspired to do this by VK3YE talk on how to get more HF contacts!)

excellent video by VK3YE on getting contacts on HF

After a great lunch in the Bongo, I decided to head out to the park for /P action !

I really enjoyed the walk around the park, I wore the Alexloop hampack bag without any problem. It was quite weighty and at first a little nervous of the straps – thinking about how much equipment and how much it costs tends to make one a little trepidatious in trusting it all to a couple of straps!

Whilst having a table/chair is my preferred ‘comfort’ of operation – and I even passed one picnic table, I liked this location, it was in the shade and the bench long enough to get everything on it without worrying about it falling off. A good bungee allowed me to strap the alexloop onto the bench, only once wobbling over when a big gust of wind came in.

It was nice that there was people interested in what I was doing, even a few comments by the passing runners on what a nice setup, as ever people where amazed with being able to make contacts around Europe – I think peoples perception of Amateur radio is that of huge Yagis and long wires, when they see the little loop and the SDR display with foreign voices booming from the IC705 they are interested to see it in action, I’m always happy to show the log book and talk about it.

I was able to make one more QSO from the bench and really enjoyed that, even on 5W of power the noise floor in the park was so good that I didnt need lots of power or a huge antenna to have a SSB contact. The fact that I had spotted on PoTA app meant other amateurs were looking for me helped for sure.

It was as easy to pack away as it was to setup from the bench, proving how versatile a well organised radio can be.

Heading back to the bongo I enjoyed seeing blackberrys growing and a giganttic overlflow carpark – it looked closed and judging by the meters had been for quite some time. I dare say this could be an excellent place to put a bigger mast and wire-type antenna up. I admired the view from the carpark once more before heading back to the QTH having had a really excellent time out with the radio. I will be back for sure and would like to investigate the bird reserve next time, it really is a big PoTA area to cover !

20 Unique calls today !

A SSTV /M Test with the Arrow hand-held yagi from 2 locations

Posted on June 25, 2022 by webmaster@hamradio.knipmeyer.co.uk

With the upcoming Hamworthy Park Festival I wanted to see if there was any chance I could reach the QTH. Previous attempts from Poole Harbour were unsuccessful with FM and the Bongos whip antenna, but having a new antenna in the armoury thought I’d give it a try.

I had already tested from the drive way of my QTH, then headed out to what is the nearest high point to my QTH in IO90BS, that of Ringwood Road near to the Matalan – IO90AS. A test of the SSTV repeater there worked well.

I then headed down to Hamworthy park, as I drove through Bournemouth and Poole the hills behind me which I knew would absorb my weak signal, but I’d thought I’ve got to give it a try.

I had the hand-held antenna quickly setup, it was fun to do it out in the field. I attached it to the THD7 and tried to reach the QTH station.

I was not surprised to not hear the pips back to transmit, but as I had driven there, transmitted anyway to see if anything would be received. I wasn’t expecting anything back as the replay mode hadn’t kicked in, so I would have to wait until I got home to see. Sure enough I had received something, albeit mostly static, but at least the application and radio could pull the signal out.

APRS Provided some interesting information. My route was entirely captured, this is due to the geography of where the APRS stations are located.

If I compare my APRS packet reception to my location of the transmission from IO90AS, the APRS station is just down the road near to Bournemouth University.

As soon as I go over the hill, all my packets are received from stations to the east.

The hills between each location are clearly visible using the useful line-of-sight tool.

Between Hamworthy Park and Corfe Mullen

So it was great to go out and test, albeit the transmission back to the QTH from Poole was again not successful I was able to gain valuable experience and APRS packet data. I think I will be able to setup another solution utilising the Bongo’s 2M whip antenna and a small laptop for the actual Hamworthy Park Summer Fete, so will put those pieces together and test those out next !

Until the next time – 73s

2M SSTV comes alive

Posted on June 23, 2022 by webmaster@hamradio.knipmeyer.co.uk

Very early on 22nd of June my IC9700 let out a loud SSTV incoming signal on 144.500 – I typically monitor the 2M SSTV band in hope of some ‘local’ activity, so I was very suprised to hear something this early.

Within a few minutes several pictures had been received.

The first i was unable to make out the full text, but the next one provided some more useful information.

SSTV message from martellotowergroup.com 2M repeater

I had never seen this repeater before and was wondering if a new one had been setup in the locality, going to the website I found that the SSTV repeater was based in Clacton – some 232km/144 miles away ! The line-of-site rule for 2M was blown away by looking at the elevation profile between the QTH and the SSTV repeater.

elevation and distance between QTH and SSTV repeater

As the the morning went on, more signals went in and amazingly i was able to activate the repeater with the access tone and receive my own picture back. I then had an excellent QSO via the repeater with G4LVD based in Ipswich !

My sent image repeated back with the MB7TV overlay

Having completed the QSO I was left wondering, how is it I could suddenly receive the SSTV repeater which is so far away. A posting to our clubs mailing list provided the insight – a temperature inversion had caused a opening on VHF between the QTH and MB7TV. Not really knowing what a temperature inversion was, I looked that up, and the met office giving a great explanation. I was just lucky to be listening at the right time and to receive the signal from so far away!

With that I wondered as these are predictable, there must be some forecast, sure enough I found a site that looked to model the inversion that was seen this morning.

https://tropo.f5len.org/forecasts-for-europe/

This means that I will be able to at least listen out at these times and try a QSO again. I’m not sure if I would ever be able to reach the SSTV repeater on mainland Europe, but with P13DFT in Delft in the Netherlands and another Germany, it will be great fun trying ! Heres to more ‘temperature inversions’ and more SSTV QSO’s on 2M!

G-0202 Garston Wood RSPB Reserve – POTA – QRP – Take 2 !

Posted on May 29, 2022 by webmaster@hamradio.knipmeyer.co.uk

Following last weeks attempt, I headed back to Garston Park to attempt activating the park again. Armed with two lots of battery packs, mains charger and the iPad with SDR-Control loaded onto it I was determined to activate the park.

Having quickly setup, I was approached by two friendly chaps asking what I was doing with the equipment I had setup. Their initial assumption was bat watching ! (Makes senses with an antenna I guess !) We had a great conversation about parks on the air and also bat watching. Its something I’ve never heard of and with this park being quite near without a lock on it, something I wouldn’t mind trying – an overnight PoTA and bat watching. I’ve looked up some equipment and the bat watching website, so I’ll be looking into that later on in the year, probably when dusk/evening comes in a bit sooner.

With that I setup the IC705 to the IPad and SDR-Control – have to say that this application is fantastic – other than having to adjust the connectors in the IC-705 if I want to use the radio independent of the app, its as close to getting to 0 touch to getting on the air in FT4/FT8 modes.

Having experimented with FT4 at home and also updated my version of WSJT-X on the QTH windows machine, I was amazed at the rate QSO’s are completed. For me with a QRP radio and wanting to try battery usage where possible (I don’t always operate from the Bongo) this was great. At the QTH FT4 contacts where made in rapid succession, likewise in the field, when an opening came, the FT4 contacts came flying in ! within several minutes had equalled my previous weeks telephony contact ! I then went over to FT8 to try my luck there, sure enough, the QSO started to come in. The one problem with Garston Wood is the really weak mobile phone signal – for PoTA you really want to self-spot to get that first log on the page, then more will follow, sure enough I was determined to ‘self-spot’ and was rewarded with more FT8 QSO’s.

The SDR Control app made logging and contacting as easy as it could be, I was amazed at how well thought out this application is. It can be configured to automatically log, which I tested for the first time today and confirm works wonderfully. Essentially this means you could run FT8 & FT4 completely hands free.

I exported the log from my ipad to my icloud storage, with a bit of simple ‘grep’ and redirection I had the file in the format ready to submission to the POTA Administrator.

cat alanpota.adi | grep 20220529 > 2E0FWE@G-0202-20220529.adi

I tried SSTV with the black cat app, but it wouldn’t integrate with SDR Control, so I tried the old fashioned method of picking up a microphone, but whilst I could pick up SSTV from the IC705 with my own ears, the ipad app was pretty much deaf out in the field. As I am great fan of SSTV this is the one thing the SDR Control App is missing – if a way could be found to integrate either the black-cat app into SDR Control so they can run both the same time, or SDR Control had its own native SSTV app, that would be amazing !

I tried a few more SSB contacts on 20m, but to no avail. With the weak phone coverage self-spotting was tricky and when I could self-spot it would take another ‘strong’ station to come in over the the top of me to make that frequency out of use to me. I tried 2M and although hearing some activity (always glad just to hear something!) couldn’t complete a QSO.

So today turned into all about Data, and how important to activate a park SDR Control is, being my 2nd visit, I was determined to get the 10 contacts to activate, and I wasn’t let down by the application. Being restricted in self-spotting also meant that when I could get onto the POTA website, I was consistent, and I was rewarded with a FT8 contact from K3VAT in the US.

I’ve had a fantastic time of late travelling around to various PoTA locations and this was by far the most challenging one so far, with limited mobile coverage, varying conditions and generally being a bit busy, it was great to get the 10 QSO’s needed to activate the park.

My next ‘planned’ PoTA is quite a few weeks off, and its getting further afield to find ‘unactivaetd’ parks, but I’m really excited about it, until then I’m going to be utilizing my season ticket for Upton Country Park, with lovely weather and long evenings, I can head over after work and set up for a fun evening of ‘parks on the air’ close to home.

Until then 73 and hope to catch you in the log book !

POTA – QRP – G-0183 – Chesil Car Park for Dorset and East Devon Coast World Heritage Site Provincial Park (Jurassic coastline)

Posted on May 15, 2022 by webmaster@hamradio.knipmeyer.co.uk

After a while away from PoTA and a previous experimentation locally with the AlexLoop only bag, it was time for my next PoTA activation. Based on my QTH location (IO90BS) I used the POTA site to find near but inactivate sites. This is becoming harder as PoTA becomes more popular (a good thing) but its always great to go out and activate a site, as the ‘hunters’ will be on the look out for a new location.

I carefully planned my trip, starting with the day before. I relinquished my beloved IC-705 purpose built bag (LC-192) for going fully Alex-Loop ham pack native. The main drawback of this bag is the lack of padding and overall robustness compared to the alex-loop bag, but I was determined to minimise what I was taking.

everything for HF ops fitted nicely in the Alexloop bag

Not withstanding the mount itself (I used a bike repair stand) everything fitted nicely in the Alex Loop Hampack bag. This includes in the ‘accessories’ my LiFo battery to keep the IC-705 running for extended time over the internal battery, which as shown in my previous ‘test’ is only good for about 2-3 hours on 5W SSB. The observant will also notice I have my iPad in there, rather than my WinTel based laptop.

I had setup and tested SDR Control back at the QTH, so it should be no surprise that it works well out in the field. What I did notice is that (to its credit) it sets the ‘connectors’ all to WLAN in the app, thus when using the IC-705 microphone (which I currently still prefer), this needs to be set back, else no telephony contacts can be made without the iPad.

Whilst the WX (Weather) wasn’t the best to be operating outside, I got setup in the Bongo quite well, at least I was warm and dry, and the IC-705 was at no risk for rain damage (one of the main issues for SoTA, its just not that rugged compared to the KX series of radios). I set about going across the different FT8 frequency/bands. At least this would be a decent propagation test and also make some contacts. I was able to tune in 40M and get the SWR down to 2:1, which resulted in 2 FT8 contacts on 40M. For a magloop I am happy with those results and on a Data mode where the key-time is longer than that for a typical HF QSO. 17M gave excellent SWR readings and resulted in 3 DX contacts. I returned to 20M and worked a further 4 DX stations via FT8, all on 10W of power into a mag loop in pretty grim WX (rain, thunderstorms)

FT8 via pskreporter – into .JP and East Coast America on 10W

Whilst not the activation I was expecting due to the weather, being able to diversify and setup in the Bongo resulted in plenty of contacts and being able to (TBC) activate the park. I was really glad to start out on telephony contacts and people thanking me to activate the park, it really makes it worth the time and travel to enjoy PoTA.

PoTA QRP Experiment – G-0362

Posted on May 5, 2022 by webmaster@hamradio.knipmeyer.co.uk

Unusually for a bank-holiday (National holiday / day off work) the weather was quite nice, I had already planned my trip to my nearest PoTA park, namely G-0362 Avon Heath, and headed out. I wanted to take a minimal setup to see how I would do !

QRP & Minimal Portable Setup

IC705
Alex Loop Hampack antenna
Laptop
Trolly for bags

I didn’t bring an external battery or even a chair to sit on, opting to just use the bench/seat at the location I was familiar with at Avon Heath. I was interested to see if I could make any contacts and for how long on only 5W and the Internal IC-705 battery. This made getting setup and on-air really easy, using a bungee to attach the loop antenna to the seat.

Telephony QSOs

I’m now starting to start-with telephony QSO’s over FT8 to get started, as such I started out on 20M as this band has plenty of activity and easy to slighty tune the Alexloop between FT8, SSTV and the Phone section of the band.

I was quickly rewarded with QSO’s into Italy and Spain, with my furthest QSO being with EA4GJP with an amazing 860 miles ! Using the MPW calculator I was getting 172 miles per watt for a 595 QSO !

Once re-spotted on the PoTA app I had a flurry of QSOs into Spain – I was rapidly getting used to telephony contacts and logging with pen and paper !

I turned my hand to FT8 but faced computer difficulties again and not having a table/chair didn’t fancy fiddling about with a cable/computer on a bench, reverted to Telephony on 20M again. I did go searching for other PoTA activations, but no chance of a park-to-park today.

With around 2 hours of operating on 5W the battery on the IC705 was almost entirely drained, but with a good set of contacts I felt happy to pack up and head home, whilst I didn’t get 10 this time out, i was glad to see just how good the IC705 and Alexloop antenna is, making it a viable QRP setup which can be easily setup and transported.

I did learn that having a battery will not only extend the life of my operation, as to be expected, but I can operate with only 5W on SSB outside the noise of QTH, which makes doing PoTA all the worth while. My next planned activation is in a very exciting/interesting place and am really looking forward to that !
