2E0FWE – AO91

Posted on June 19, 2022 by webmaster@hamradio.knipmeyer.co.uk

Today (19/6/22) was my first attempt of using satellites put in place for amateur radio. Having read up and joined Amsat (a very modest fee for quality content!) I targeted AO-91 as my first satellite.

I could see there was at least a possible chance of making a contact at 09:14 BST, so I set out with the Arrow II 146/437-10WBP 2m/70cm antenna and my TH-D7 hand-held.

Having got the antenna built and radio ready (I pre-programmed the optimal tuning in the shack) I setup a comfortable postion to operate from.

I made sure i was ‘aligned’ to the sky with a real magnetic north compass to ensure that I would stand the best chance of being able to hear the satellite as it came over on its relatively low and short pass.

I was astounded that with pointing the antenna on frequency I was soon hearing QSOs from Italy and the Netherlands via the satellitle on 2m and 70cms. As I was about to try calling my THD7 stopped working ! In a rush I got the THD7 plugged into the Bongo power and could continue to receive, but was unable to complete a QSO this time.

Whilst the battery had got the better of me making a QSO, I was really happy that the antenna and receiver worked and even on a ‘low’ short pass I was able to hear QSO’s. I was amazed at how quickly people gave callsigns and grid locations – there was little time more for anything more – I can see why people recommend recording contacts on satellitle and make the log book after.

I headed back to the shack and tried the AA battery pack that came with the THD7, this also failed to power the radio, so I had to engineer a solution ! I found a ‘spare’ connector from an adaptor set and ‘butchered’ that to make a DC power supply from the batteries I usually use on the IC705, these would be more than enough power for the THD7, even with the squelch fully open, to operate receive and transmit for the times the satellites came over.

Conclusion

Whilst my first attempt at satellites didnt result in a QSO I gained valuable experience and could confirm my antenna and transceiver worked correctly. Whilst the in-built battery was bad, and replacements unreliable/dangerous, I was able to manufacture a replacement. I’ve since ordered a ‘cheap’ Digital voice recorder and headset for QSO’s – I think I have a splittler cable, but will find out when the digital recorder arrives how to drive both headphones and recorder.

In all I was very happy to go from 0 experience, to at least listening, which is pretty much what I done on all the bands in the past anyway, so was very happy to make my first steps in amateur radio satellite communication.

Jubilee Decorations at the QTH

Posted on June 3, 2022 by webmaster@hamradio.knipmeyer.co.uk

With a long bank holiday weekend for the Queens Platinum Jubilee I set about decoration the QTH. Whats the ham radio connection ? Well I mostly re-used antenna masts for the bunting and flags.

After an hour or so I got the bunting and flags up. One line of bunting accidentaly on purpose got caught up in the defunct TV antenna. As it was providing a good support to the bunting, I left it there !

For the Union Jack flag pole I took down the defunct NOAA antenna which is supported by a awesome Barenco tilt base, this makes getting masts up really easy.

I guyed up the mast it does get it bit blustry in that corner of the garden as its not shielded by any trees/houses.

For the bunting I lowered the 80m end fed antenna on the DX Command mast and hooked it onto one of the guying plates, it went up really easily, that mast is pretty bullet proof and the guying plates are extra strong, allowing the bunting to go over it, with plenty of distance between both (I dare say a few watts in the wire could effect the plastic bunting !)

Dx Commander holding the 80m end-fed wire and bunting !

For the other bunting I used a Sotabeams mast attached to our garden umbrella. It has a fair bit of ‘lash-bonding’ and then sizeable weights on the base to keep it vertical. During raising the bunting flapped around somewhat and got caught in the TV-Antenna ! I did attempt to get it down with another Sotabeams mast, but it is pretty tangle around the base of the TV Antenna ! So I’ve left it there for now.

I was happy to get all the bunting and flag up, I vividly remember the jubilee from 1977 and the street party then and what a happy occasion it was. Thankfully there is a street party tomorrow and am hoping the good weather holds out, its been plenty of fun putting the flag and bunting up and I hope it sets the jolly atmosphere on the street off (although the lower half of the road at the QTH).

Happy Jubilee weekend to you all.

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-0202 Garston Wood RSPB Reserve

Posted on May 22, 2022 by webmaster@hamradio.knipmeyer.co.uk

Finding unactivated parks around IO90 is becoming hard, thankfully there are stil a few, one of them is G-0202 Garston Wood. With only a short drive and beautiful weather I headed off to the park.

The drive in the early morning (approx 7:30AM) gave stunning views and morning mist, I was glad to have sat-nav as the lane leading to the park was very narrow and with all the trees having all their leafs was very green ! I found a nice spot to park and setup my mag-loop antenna on the bike stand. The gates to the park were near to hand as well. There was plenty of parking space at this hour, and it didn’t get much busier in the time I was there (2-3 more cars parking max)

Unfourtantly when I arrived I noticed I had left my iPad behind ! Not a disaster, but that meant no digital modes such as FT8 or SSTV, and I was looking forward to SSTV, still undettered I tried for making 10 Telephony QSO’s! I started out ok, making contacts into Spain on 10W. Having learned last time that repeating calling CQ is tiring after a while (thats when I usually switch to FT8 now) I used the 705 in-built voice recorder to play back my CQ POTA call.

This got me another contacting in Poland, and my first ever Park to Park ! I found this really satisfying not only on the DX but reaching another park and getting a good signal report both ways (mutual 59) with SQ5MPG – Maciej in Poland at SP-0643 – Los Nature Reserve. What is more tricky with a park to park is getting the callsign and park locator correct, as this is required for logging later on.

I tried staying on 20m, but it was soon filling up with contest and people with far stronger signals than my own, I’d like to think they just could hear me being only on 10W and that goes with being /QRP that you’ll get more powerful stations boom over you higher up the band. I tried 40m and 17m – with 17m being a non-contest band, but to no luck on either, so headed back to 20m.

I made one more contact, another park to park with EC2AG (Antonio) into EA-0837 (Rio Agüera EU Natura 2000 Protection Area). Again, great DX and made the full Park-to-Park contact. I thought my battery had become disconnected, but it turns out for the first time ever I had drained the LiFo battery completely ! I guess this is what using the voice-record repeat for serveral hours will do, and I was reduced to 5W of power.

I returned home as my battery and power wasnt helping, and with so much contest traffic on, it was getting harder not easier to even make any initial contact. I made notes on my log book of the things I had missed today to remind myself of what to add when I got home, so as you can see this time I have added the USB cable and cigar-lighter mains adapter for the IC705 into the alex-loop hampack accessories bag. Of course I have put the Ipad in there as well 🙂

Whilst I didnt get 10 contacts to activate the park, its will mean I can make a return trip and be better prepared. I had a great time and the two park to parks were extra great, so am looking forward to returning, iPad and mains-power in hand !

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 !

First state-side SSTV contact (5/5/22)

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

Being up and about in the small hours in the UK I was tuned into 20M SSTV frequency of 14.230, thinking just to let it monitor and pull in the overnight SSTV pics only to find a clear as a bell TX start from W2PTH.

For those who are new to SSTV, W2PTH has been doing SSTV for quite some time, his QRZ Page states 1976 ! Those familiar with SSTV would be familiar with the call sign and the ‘Cherry hill’ location appearing in his pictures.

Having heard the call, I thought to give it a try – I’ve never had much luck in reaching the states being limited to 50W but the signals where coming in exceptionally clear tonight, so thought to give it a try!

As you can see the stream of pictures came in just wonderfully and I was really happy to have W2PTH in my log book with my first DX contact into the USA.

Propergation differences just minutes later

As can be seen from the picture received just minutes later, the conditions had changed. It was fantastic to have such a great SSTV QSO with a great operator!

Equipment Used :- IC7300 50W power, Multi-band End Fed Antenna, MMSSTV on Windows 10 with KE5RS FTP Widget for uploads

Kenwood THD7 APRS & GPS (Bongo is back!)

Posted on April 4, 2022 by webmaster@hamradio.knipmeyer.co.uk

Firstly the Mazda Bongo is back from Wales after the brakes have been repaired in Bangor ! Very grateful to Kevin at Bangor Kwik-Fit for sourcing all the parts required to get the Bongo back on the road.

Replacement caliper, disk and pads on the Mazda Bongo

When I returned home I found a package from America waiting for me, which turned out to be the connector cable between the Garmin eMAP and Kenwood TH-D7. The only place I was able to find this was an on-line shop in the USA.

When I contacted them they was unable to ship to the UK ! I contacted a friend in Portland who was kind enough to order it for me and send it on to me here in the UK, I was really grateful to get the ‘final’ piece of kit required to use APRS and GPS with my Kenwood TH-D7.

I setup the emap and TH-D7 to produce packets via the beacon method and setup my home computer and IC-9700 to relay APRS packets.

Whilst I have a dual-boot machine, for simple reception and digipeating I’m able to use Direwolf in Windows. I was able to ensure my APRS packets are being transmitted and received before going out and doing a field test.

I headed out with the Mazda Bongo on a trip to one of our local farm shops and then to Poole harbour which made a nice way to spend a trip out and combine with some real data creation.

On return to home I was able to look at APRS.FI and see my route had been nicely recorded and received via various Digipeaters around the IO90BS area. I was quite suprised that the coverage was as good as it was giving the hilly nature of the route and small low-powered 2m/70cm antenna on the side of the Bongo.

Clicking on anyone of the data points will show all the data received and relayed, and from where. In this case we can see I was doing 22MPH on a heading of 101, this was received by M0VPN-1 whereby it was then put into APRS.FI website.

Conclusion

Whilst it took some time to get all the components I needed to get GPS and APRS working with my older Kenwood TH-D7, it has been well worth the wait. I can now setup position reporting and include useful messages, this will be in particular use when en-route to amateur radio activities (weekly club, conventions, POTA activations) and to send messages to other APRS users.

I would recommend that if you are looking to get more from your 2m/70cm experience and have the budget invest in a radio that has GPS & APRS, it may not seem obvious as to why it could be useful to start with, but certainly could be something you may well find yourself using when you have it.

QRP – POTA – G-0211 – Upton Heath

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

With the weather being so lovely and time allowing day time operation, I headed out to Upton Heath – this is just opposite Upton Park but separated by the busy A35. Although once in either, you wouldn’t notice that it is there !

Upton Heath (G-0211) and Upton Country Park (G-0443)

I brought my wagon along to help transport the radio and accessories from the car to the heathland, with just a short walk to find a good bench to operate from it was no problem at all.

I was able to be on the air quickly with the excellent Alex Loop ham-pack antenna, I used a bungee to attach it to a direction post as my bike stand is still in the back of the bongo in North Wales, but the bungee was excellent to use and changing frequency across the 20M band was very easy to get low S.W.R. across the operating frequencies.

I wanted to get better at Telephony contacts so started with Phone on 14.241 and used the PoTA App to self-spot, within minutes I was trying to manage a pile up ! I was getting so many call signs at once, it was hard to distinguish them and get back, thankfully I got most, but some I couldn’t complete, but that’s what experience and patience will teach me ! I managed 6 Phone contacts, whilst I appreciate all of them, it was great to get a fantastic signal report from K1RO in New Hampshire ! I was so glad to have a break and a drink of water with me.

I then moved onto FT8 and completed enough QSO’s to active the park, with reports coming in from all over Europe.

Whilst I had been operating for just over an hour, I wanted to give SSTV a try, my previous attempt was thwarted by a very busy 20m band, but today I was able to get thru a fantastic signal from HA1AD

With my water supply fast running out and time getting on, i packed up having had a fantastic time at Upton Heath. It is definitely a park I will come to again, its nearby, really accessible and lovely location to work from.

Bongo Broke and Sudden Local PoTA

Posted on March 22, 2022 by webmaster@hamradio.knipmeyer.co.uk

So I planned my trip to Wales carefully, ensure that I had packed all that I needed for my weekend in Wales. I booked a campsite, only to find when I got there they don’t open the main gates until 8AM, so that would mean being late for lectures ! Instead I stayed at the lovely Bangor Business School Hotel – not as cheap as camping, but very much getting me there on time and a good nights sleep.

Sadly on the way up the Bongo’s breaks made the awful noise of metal on metal, so on Thursday I booked it in for a Saturday ‘break check’ – low and behold, new disc, pads and caliper required ! With that my planned PoTA activation for Snowden was off, and I headed back to Bournemouth via Train whilst my Bongo is repaired in Bangor.

I unloaded my radio, alexloop and computer along with my suitcase from the Bongo, a total of 4 bags. The train required no less than 3 changes and the underground – but in all this travelling the alexloop and Icom bags really proved how good they are. The Alex loop is incredibly light and was easy to carry, whilst the IC705 and the radials was slightly more weighty, choosing to carry that one on my back it was easy to carry around. My other bag continued 2*Battery so weighed a fair bit, but wasn’t to bad.

It took about 9 hours to get from Bangor back to the QTH in Bournemouth, but I had done it ! Only thing which I had ‘lost’ is the antenna of the THD7, on the scale of things, I wasnt going to complain ! (it must of slipped out the bag at some point)

With that doing PoTA from the Bongo is on hold until I get it back, hopefully this week if the caliper arrives in time ! (which means a return train trip to Bangor, luckly I love trains 🙂

POTA 22/3/22 – Upton Park

The weather in Bournemouth is being fantastic, not wanting to bury myself in over 40 research papers the whole day, decided to go out and do a local activation at Upton Park – I have been there to visit before, but not for PoTA. As it was so nice, I really wanted my XYL Monica to come along as well, as there is plenty of facilities there, i.e. tea/coffee/light snacks and decent clean toilets, all within a short walking distance from the car park.

xk8 – faster than the bongo, but not quite so good for radio within it !

With the Bongo still being in Bangor, the XK8 is getting plenty of action, whilst I cant easily operate, it got all that I needed and XYL to Upton Park without problem.

To activate a park, you only need to be within the boundary, and as the tea room is within the boundary of the park, was a perfect place to setup. There was some curiosity as to what I was doing, but no problems with putting my alex-loop in the table and then running my laptop into the IC705, we bought some nice tea and cake, plus a bottle of water as the temperature was really getting up at midday !

Even with the antenna in a compromised location, I was getting out just fine on both 17m and 20m.

As soon as I self-spotted on the PoTA app, i was getting more calls, amazingly 2 from the USA ! Albeit FT8, it was really satisfying to get so many DX contacts on 10W.

For the first 30 minutes, the contacts came in very quickly, but after 12:30 there was a real slow down – i said to XYL Monica that if it was only 2-3 contacts made, I would of come back the next day (you can do activations over multiple days) but I was on 9 and need just one more ! I tuned to 20M and sure enough made my last contact there quite quickly once I had re-tuned the alex loop and found a clear part of the FT8 bandwidth to operate in.

With the 10 contacts made which are required for a park activation, I packed up and we headed out for a lovely drive around the Dorset countryside. At home I processed my manual log thru the excellent Excel spreadsheet to produce the ADIF file and sent that off to the regional POTA administrator, hopefully my results will be processed in the next day or two..
