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.
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 !
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 !
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 🙂
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 !
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.
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.
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.
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.
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.
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.
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 !
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.
UV5R THD7 River StourAnother nice RXSweety was really enjoying the walk
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.
Beautiful swansAnother great RXv.slight interferencevibrant colours Great RX and TX
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!
another fine replaythe furthest distancebird spotting location
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.
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.
Received picture at QTHreplayed picture receivedSSTV Testing from IO90AS
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.
Route captured via APRS
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.
APRS received via 2E0UXV
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.
Hamworthy Park – QTH
Between Hamworthy Park and Corfe Mullen
A much better chance of reception
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 !
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.
SSTV Test Card – source unsure
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 !
via MB7TV G4LVDMy sent image repeated back with the MB7TV overlayCompleted QSO via MB7TV to G4LVD
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!
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.
Bike-Stand mag-loopThe entry to the park..Setup time
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.
Bat detectors – yes they exist !
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.
Digital modes via SDR ControlRapid logging
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.
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.
excellent world mapFulll QRZ logSDR Control LogFT4 and FT8 saved the day – and the SDR Control App
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 !
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!
SSTV QSO with W2PTH
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
So its been a busy couple of weeks with much non-radio stuff going on taking up a fair bit of my time. I did get to enjoy going along the south coast, but no time/equipment with me to do any radio this time out, but nether the less I had a great time.
Waking up without a hangover on the south coast
Whilst radio activities have been minimal, mostly the weekly G4PRS net on 2M and FT8/WSPR on HF, I did give a presentation about “Parks on the Air” to the G4PRS club. This was also shared over Zoom for those unable to attend in person.
This went down pretty well by all accounts, I got plenty of positive feedback the next day which was good to see, but I could see that 2 years of lock down had effected my presentation skills for sure, nethertheless it was a good way to get people into PoTA.
With the longer days I’m sure to do more nearby activations soon, it makes a break from studying/reading. I did have some interesting FT8 contacts on 10M recently.
10M FT8 contact into Hong Kong
I hope I can get in some more PoTA before the end of April and am looking forward to the increased propagation conditions.
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.
Wagon/cart for easy transportBench as a deskAlex loop on direction postPortable operation location in Upton Heath
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.
FT8 – 20m
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.
