POTA – FT8, FT4, SSTV, SSB – UPDATE – 18/3/24 –

Posted on by

After a very busy week, I had Sunday and getting out with my radio to look forward to. Thankfully the weather was being kind to me, whilst not warm, it wasnt raining as we had plenty of that over night !

Plenty of overnight rain at the QTH

I headed out to Boulderwood with the magloop and 705 and was on the air very quickly. Setup is quick and easy with the magloop and I actually learned a good wait to tune the antenna and get the SWR down quicker.

place hand UNDER feedline when tuning = better and quicker matching

I did run into issues starting out with WSJTX and FT8, the time on my computer was just ever so slightly out, but enough for a time sensitive decode of FT8 not to work correctly. I tried updating the time using the windows time server, to no avail ! I had to manually set the NTP server to rolex.ripe.net, sync the time and I was back in action !

I had 10 QSO’s in digital modes done in under 40 minutes, shifting between FT8 and FT4 on 20m, with POTA hunters chasing me thanks to the POTA app and RBN.

Having completed enough contacts to activate the park, I was straight into Telephony and SSB. I went onto 17m, not that was any contests on, but I found it a good band for QRP operation, and sure enough I made two contacts, with EA1EC being a POTA Hunter, proving how using PoTA makes getting contacts that bit easier – when running QRP it all helps !

I jumped onto 20M, which was quite calm for a Sunday, and was able to tune around the band, making a contact with IK0VSY, with a good signal report. 20 meters really was the place to be today, so jumped onto SSTV and the pictures started rolling in from other SSTV users.

I waited my time and started to transmit and I made my first SSTV PoTA contact for 2024 ! I was really chuffed and excited, so big thanks to IK2QIN for the excellent QSO.

SSTV QSO received and uploaded to MAX SSTV by other SSTV receivers (Thanks MAX SSTV website!)

I then span the dial on 20m once more, and made 3 more SSB contacts, it was really great to make the contacts, with IU3EDQ being Portable !, but thanks again to EA2DT and EA4TL for hunting me and making the contact with excellent signal reports, with a 59 from me and a 5-5 for my reception report.

The IC-705 really done me a great service today, and being able to use the the voice repeat mode in conjunction with the ‘massive’ battery power of the ‘ultra max’ battery ensured I wasnt going to run out of power for the radio.

on 20m and good results
repeat mode saved my voice

Sadly some massive QRM came in on frequency, but I was able to shift up and continue making contacts, that is the advantage of 20m over 17m, that it has more space in the band, so shifting isnt a problem. I quickly posted my frequency change on the POTA app and was able to continue making contacts !

QRM on frequency, maybe a new mode I’m not aware of !
the sun did try to come out

As the time approached for me to head to the supermarket to get my essential shopping, i packed up in no time, leaving the bunch and the park as I found it. Bolderwood is such a lovely place to come, its relaxing and gets me ready for the busy week ahead. I had a fantastic time getting out on the radio today.

Big thanks to all the people that made a contact with me today, it really is much appreciated and I really enjoy the amazing hobby that is amateur radio !

thanks for all the contacts !!!

*update 18/3/24*

Would like to say BIG thanks to Alessandro who contacted me with his QSL card, little did I know at the time that IU3EDK/P was up a mountain ! I received a lovely QSL card via email and a link to the activation – how amazing that it was a park-to-mountain activation all on 10W of power !!

Thank you Alessandro ! Please check out the activation from Alessandro here

Having worked on antenna projects at home and with good weather the urge to get out and get on the air was strong ! This time it was an morning outing to the New Forest and Bolderwood, which was unsuprisingly busy with familes, dog walkers and folk enjoy the lovely surroundings of Bolderwood.

New Forest map in Bolderwood

I setup the 705 and Alexloop, although struggled with getting the loop on securely this time out, just figured it was a case of over familairity – sometimes it just goes ‘on’ but this time it was being a right rascal ! Still, i was on the air quick with the radio setup. I jumped on 20m and started with FT8. No sooner had I self spotted the flow of contacts coming in was amazing !

In no more than 30 minutes the 10 contacts to activate the park was complete – even with a pile up !

The FT8 contacts came in from all over Europe, I was making it into the west coast of the states, but no QSO’s that far today unlike last weeks greyline activation.

FT8 on 20m – great reach with the magloop and 10W of power.

With the 10 contacts needed to activate the park and enough battery for both laptop and radio I tried SSTV, but it was very busy today. I found it slightly annoying that some people seem to serial transmit and dont leave a gap for a response. At least two times there was the same person calling CQ without leaving a gap and just retransmitting, I did however manage to capture a screenshot thanks to the cool CQ SSTV website which pulls in reception of SSTV sites.

received in NL on 10W

I tried a couple of times, but the QRM from interference on the band, as seen by the horiziontal lines on the image, was just getting stronger. I jumped over to 17M being a non contest band and generally good for QRP operations.

My first attempt on the QRP CoA resulted in a partial call sign and no signal report, so I moved further up the band to find a gap. I wasnt to be disappointed and made 3 great telephony contacts on 10W, it was a great experience mix up the PoTA activation with SSB phone contacts, with good reports.

3 Telephony contacts on 17m – DM5MU booming in on 3W

It was great that two of the phone contacts where made my PoTA hunters, showing that the app really worked well. Getting pulled out using low power is a challenge, but great when those signal repots come and the QSO’s are more than the FT8 signal report/ACK. A fine example of this was the SO with ‘Andy’ and DM5MU, who was happy to chat about his amazing Yagi which was running very low power but booming into the new forest with 59+10db! My signal reports was just as good with 5/9!

With all the fun and excitment of making rapid contacts on FT8 and Phone contacts on 17M I felt i had a great time on the radio, I was able to at least get a SSTV decode and enjoyed doing PoTA – one award is the ‘repeat offender’ which is 25 activations from the same location. As the new forest is quite big, its possible to goto other parts and use the same PoTA reference, so something I’m most deifneatly lookin at doing as the year goes on !

Thanks to the PoTA Hunters ! Esp on Telephony ! 🙂

A big thanks to the PoTA huters, esp those who work me whilst I’m only running 10W and patiently give me their callsign and signal reports, it really is a great time out !

Until next time 73 ! 2E0FWE

G-0112 – Bolderwood New Forest, Alex Loop to the rescue

Posted on by

With another bright but cold day, it was a good time to get out and get on the air. This time I was packing my trust Alexloop Ham pack antenna along with the IC705, determined to make an activation on my 3rd attempt from Bolderwood.

WX – I caught the ‘warmer’ part of the day at round 9 to 7 celsius

I was no sooner out the car and onto one of the many available benches and quickly setup. The alex loop was out the bag and with a bungee hook strapped pretty tightly to the bench. I tuned for 20m and got a great SWR of between 1.3 and 1.4 but no more than 1.5 and 10W of power. The FT8 contacts came rolling in, and with a busy 20m FT8 was then onto FT4, for even quicker overs.

Alexloop Setup
Manual Logging

It was great to get a mobile phone signal as I tethered my laptop to the phone wifi and could upload my contacts directly to QRZ via the excellent grid tracker application, I still kept a manual log so it would be easy to confirm the order and QSO’s I had today. The Reverse Beacon Network and POTA app was doing me a great service, as quite a few of my contact were POTA hunters. Getting 10 contacts in under an hour was great given just how cold it was, it was nice to see 5 of the contacts are POTA hunters.

I gave SSTV a go, but the signal where coming in thick and fast, I started to see a response to my transmission, but another station came in over the top. I try to use Robot72 and BW12 to keep my over time on 14.2300 short, but most people dont QSY on SSTV, and even then we tend to get other people talking over the SSTV CoA on 20m as well..

Still, having uploaded my ADIF file from WSJTX to POTA I was soon awarded my 2024 activation. Just in the nick of time ! A good start to POTA in 2024 !

POTA 2024 Award – a good start to the year

I am really excited about getting out and do more POTA – its a great start to the year !

IC705 USB Cable Choke

Posted on by

So a quick update, having received the 5M USB cable and cable ties, i then went on to test out the choke method to reduce/remove the inteference from the IC705 as shown by Temporarily Offline Ham Radio video included yesterday.

toride and USB cable wrap
quite a few turns
No interference on IC705

The RF Choke comes from here, as I dont suffer RF back into the shack thanks to the EFHW and RF Choke on the feedline, the PSU Choke was not being used. Winding the toride was made quite easy by the fact the choke can be opened up and wound up, once secured with a a couple of cable ties it was easier to put the turns into specifc locations, tighten the cable wraps up, then cut off the excess.

WSJTX in action – no sign of disconnects or loss of audio

I tested MMSTV and WSJTX into the 2M Comet Whip antenna, everything worked fine with no issue of disconnected audio or interference into the radio or the computer. I’m looking forward to taking the setup out and trying again with the Toybox whip antenna to see how it does this time out.

Egg Beaters – for the hard of hearing

Posted on by

Firstly Merry Christmas ! Its a relaxing day here and not the usual busyness for a Monday! Having an extra two days for the weekend has been really nice, I’ve done loads of other stuff and also playing with IC-9700 with the satellities, or attempting to, would be more accurate 🙂

So far I’ve heard zilch, as in nothing, not a tweet from a ‘bird’ I looked up Amsat’s tracking of sats other had heard, so would be confident that I should be able to hear them too, alas to no avail. I then tried FT8 on 2M, I was getting out just fine with the eggbeaters, but not hearing a thing, I did notice some very high peaks of QRM on the WSJT-X ‘scope’, so my first step was to move the antennas further from the house and a better line of sight of the sky to the horizion, which accomplished, well, nothing.

I then tried SSTV via a my hand held units into the IC9700 and MMSTV, this worked fine, so the 2M antenna was at least receiving and transmitting. I went to 70cm and found a clear frequncy and gave the same SSTV test, this worked fine… so what was going on ? Ok simple test, lets swap antennas between the Diamon X3000 which goes into the Kenwood, put that onto the 9700. Again,

WSJTX FT8 2M

No problem getting out with FT8 and no problem on SSTV. I tried WSPR with 5 watts on all three antennas, the egg beater 2M worked fine.

WSPR on 2M

I then checked thru the IC9700 settings, all good there and used the manual ATT/P.AMP switch on the front of the radio it self, what I noticed was that the internal preamp did increase the signal, but with the external pre-amp there seemed no increase in performance.

What I suspect is happening is that my mast-head pre-amp is designed for a single feed of coax into it, then into a single verticle antenna, where as I have splitters each end for taking the coax and seperating out the 2M and 70cm bands. By the reckoning I can hear local 2m fine (including MB7IPD) on the egg beater, I suspect that the 70cm RX is doing nothing, although the antennas resonent for TX, I think the multiplexer and multiband masthead are not working together correctly.

As its getting dark now, and have the luxury of another day off tomorrow, I will research which sat’s are most common and which band the RX is the most common, then I will setup a single feed for that antenna into the mast-head amp, and run two feeds from the egg beaters, then I should be able to find out if its the egg-beaters/coax/multiplexer causing the lack of ‘ears’.

Until then, 73’s

Back from Holiday

Posted on by
The view from our room in Montreux

Having had a very nice holiday at the start of the month in Montreux Switzerland I had disconnected all my antennas to ensure no damage to equipment whilst away. With a busy schedule its taken several weeks to get the antennas hooked back up again, but I’m glad to be back on 2m/70cm and HF.

Thanks to the book-shelf shack rack, the anteannas were easy to reconnect for the 7300, Kenwood TM-V71 and CRT6900. I was back on the air monitoring SSTV in no time at all and had a good QSO with OE6XFX on 20m with a good signal report (595) on our transmissions. The 20M SSTV was busy as ever for a Saturday afternoon!

seasonal SSTV pictures on 14.230USB

I monitored the Southampton repeater on 70cm and 2M Poole gateway and plenty of activity, was nice to hear some good technical discussions goin on the 70cm repeater in Southampton, was nice to listen in.

I’m hoping for more good weather over the weekend so I can continue work on the eggbeater antennas and looking forward to getting those going on the 9700.

Until then, catch you on the airwaves and 73 !

New Forest POTA G-0112

Posted on by

With a second bank holiday in quick succession and the WX predictions for the bank holiday being ‘traditional’ I made a impromptu POTA activation in the New Forest. Whilst its not my nearest POTA, there are plenty of nice quite places to go, so I headed off for a evening of radio fun !

As is norm for me, I started out with FT8 – or should I say after some reacquainted got started with FT8 ! As I wanted to do SSTV I used my old laptop and USB cable. This has been running at home nicely for months for WSPR via the IC705/Laptop combo, sure enough, go out in the field and it starts playing up ! Firstly experienced disconnects on WSJTX on anything above 5W, and remembered that I had setup the 705 to be a 7300 to allow MMSSTV to use the same ‘hex codes’ – once I got the power and connection sorted, was soon on the air and the QSO’s started coming in. 17M was very busy but propagation good, the magloop and 5W was getting me all over the world, was very glad to see several contacts into the states from POTA hunters.

5W into magloop on 18 and 20m (FT8 / FT4)

I was soon getting drowned out on FT8 on 17m, so switched to 20M and FT4, whereby i was able to get the 10 QSO’s needed to activate the park. I then switched to SSTV. Receiving was fine, and the absence ‘noise’ produced fantastic RX. I thought I would give it a go, even tho I was ‘limited’ to 10W.

excellent QSO with OK1DNT
MMSTV working well with the IC705
enjoying POTA SSTV

A very good signal came in from OK1DNT and was reward with a 595 signal report on 10W ! I was overjoyed that the magloop, low power and noise floor worked so effectively. It really was a highlight for me and I think I shall work out how to the webcam on the laptop to capture some ‘live’ PoTA pictures, each time I’ve tried SSTV on PoTA, I’ve made a QSO, so it is most defineatly a viable mode with QRP power. Thanks to OK1DNT for the QSO as well !

I headed home with the Retevis RT73 working nicely doing its APRS positioning beaconing. Whilst the RT73 doesn’t have the TNC/Packet capabiilities of the THD7, it nethertheless does a great job of position reporting. I did struggle with updating the message, but I got it to read ‘POTA G’ I struggled to get numbers and symbols, so will investigate that next time. The RT73 is a ‘neater’ solution for 2m/70cm operation, tho admittedly I’ve not a QSO on it yet !

APRS via Retevis RT73 working well

En route i encountered the lovely horses/ponies of the new forest. I do love the nature and animals in the beautiful scenery.

Once home and unloaded from the Bongo I set about logging. I always use a manual log, even for digitial modes, incase something should happen to the computer/device I used. I was pleased to see some very cool new features on the POTA website, in that its possible to create a manual log via the PoTA page for submission.

Manual log
beta model manual log
adding the QSOs

I watched a video on how to do the manual log, shown below and it was easy to follow and create my own log submission.

POTA Manual Log Entry

Sure enough my log submission was done, it was so easy ! Also I could export the ADIF file and upload to QRZ

POTA ADIF to QRZ

Whilst the frequency and signal reports were not the ones from the event, it did at least have the time, band mode and contact, not bad at all and acertainly allot easier than when I first started POTA last year.

Overall, despite the early technical frustrations I really enjoyed this activation, it has made me think about a PoTA strategy for digital modes, i.e. use the mac ipad for FT8/FT4 and laptop for SSTV, if the ipad app had SSTV capabilitiy, that would be amazing, but its a great app as is being totally ‘wireless’. Still, I look forward to more PoTA as the year go on !

Thanks for reading and 73

More live streaming with G5STU. SSTV Contacts and upcoming POTA news!

Posted on by

A quick one today, so had a great time watching and being part of the live stream for G5STU. Was great to make contact again with very good signal reports – being very close but hilly terrain between the QTH and Poole Harbour was good to get in the log and hear myself back. Not quite BBC Radio quality on the pronunciation on my part, but not as terrible as I thought. Still, great work on G5STU to run these live streams, its great to hear so many other people and enjoy listening live as well as the live-stream.

SSTV

DG0KT SSTV QSO

Had a great time with a very nice SSTV QSO with DG0KT, great signal reports for what was a very busy 20M with both SSTV and QRM coming in from other operators bleeding into the 20M SSTV Center-of-activity.

POTA

I have a POTA activation planned soon, usually I go in my Mazda Bongo camper van, which has developed a stall fault – the indication is that of fuel starvation (runs but stalls) and having checked the ‘banjo’ filter found nothing wrong there, have ordered new diesel fuel filter.

The suspect fuel filter on the bongo

The fuel filter should arrive on the 13th and hoping its a quick swap-out to get the bongo back on the road ! In the mean time I’ll be going in the XK8 – which will be interesting as whilst its a more comfortable car, getting it setup with a radio and loop antenna will be interesting !

xk8 for POTA (XYL featured)

Until next time keep well and enjoy radio !

Telephony QSO’s – What me ?

Posted on by

So my biggest constraint of amateur radio activities is, yep, time. Mostly I run WSPR and monitor via the webtechnologies site for how well the IC705 and 6BTV are doing, as well as pull in the automated SSTV broadcasts from 20m available here.

So why the sudden ‘burst’ of telephony QSO’s – mostly thanks to scheduled (scheds) transmissions, firstly the most excellent 145 alive event organised by G5TM and then the regional contacts that setup out in the field.

2 Meters Alive event by G5TM

I was lucky enough to contact G5STU who setup nearby – very line of sight, but was great to hear all the other people in. I did manage to make one other contact on the ‘net’ but left it to those with better setups to enjoy the QSO’s, it was great to listen in !

G5STU – 145 Alive

Not one to rest, G5STU then setup a live stream of his activity on 40M – based in Poole ! I thought I had to give it a try, to me on 2M Poole harbour is complete black spot due to the hills between the east side of Bournemouth and the low side of Poole, so thought it worth a try to have a QSO with G5STU, sure enough, was my first HF contact so near, was great to get in the log book.

So whilst I’ve been manicly busy, its been great to take time out for those that organise live events that are fun to join in with – I’ve scheduled my next PoTA – which will be at night during the week ! So am looking forward to that, I have no idea how I will do, but the main thing is to get out and enjoy radio.

In the mean time, I’ve setup the MFJ993B to get on top-band at home, and am able to hear the various ‘nets’ that occur, as well as get out nicely on FT8 mode, having made several QSO’s on top-band on a non-resonant 80m end-fed antenna, i was very happy that the MFJ993B got some action !

Top-band FT8 QSO’s

So, hoping the end of January and start of Feburary will allow more time for radio, more project parts are arriving, allow things to progress on the VHF/UHF and Microwave bands, so excited to tell and show more about that 🙂

Until then, 73.

QTH – Digital Modes

Posted on by

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.

EA3AUW SSTV QSO

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.

IU5KZF – SSTV on 20M (14.2300)

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 !

1W WSPR Reports – DX into VK on 1W!

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
