With getting reading to go POTA next step was to check the PC hardware, I previously used an apple tablet for IC705 wireless connectivity, but this lacks SSTV which I like to use. First step was to get my very old HP Pavillion laptop up and working with the IC705 !
First step was to retrack and setup the settings in the IC705, for this the first part of this video got the required settings. The app to control the radio here is Icom’s own, which I dont own a copy of, but it sets up the Wifi and necessary settings, also like that its a profile which can be easily loaded/unloaded.
setting up the IC705 for Wifi operation (first half applicable)
With the wifi setup correctly (I had to adjust the audio filter bandwidth and CI-V Echoback to OFF) I then set about setting up wfview, using this tutorial.
IC705, Wifi, VBAudio, Virtual COM port
This got me to the point whereby I could receive fine, but transmit didnt produce any audio, I rechecked the settings on the radio that Inputs/Connectors/Data MOD=WLAN and no issue there. I check wfview and the settings are correct, I did notice my version of wfview was 1.5, so check the forums, sure enough, others had the same problem and was fixed by an upgrade.
I downloaded the latest wfview and installed. I did notice this didnt overwrite the previous version, so I found the new version (C:\Program Files\wfview) and made a nice desktop shortcut, the registery settings had kept the config, so no need to re-enter all those thankfully.
I attached a Diamond RH770 2m/70cm antenna to the the 705 in the shack, just for something to transmit into, RX was flooded with QRM from all the computers and screens, but amazingly with 5W of power I was picked up by WESSEXSDR!
So.its now all looking good to use my oldlaptop with newer versions of wfview for at least WSJTX control. Hopefully just pointing MMSSTV and the virtual com port (10) and audio to VBAudio will get that working, but will wait until I have a HF antenna hooked up to test that ;o)
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’.
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.
Having got the ‘shack’ into somewhat more operational functionality I pondered adding back in the MFJ Auto Tuner – I originally purchased this when I was using home-built vertical antenna and in that it could seemingly tune anything to matching the impedence of the antenna to the transceiver. With the 80m end fed, which does a excellent job across all its designed bands, it became a little redundant and sat in the ‘spares pile’.
With the recent ‘ham shack’ rejig and spotting the tuner, I’d thought Id give it another try, as digital modes on top band can experience some interesting propergation and having recently got the weather station back on line ready to start re-building the webtechnologies for WSPR data, seemed a good reason to at least put it back in place.
MFJ ATU under the IC9700 doing its business on top-band WSPR
Fitting in the ATU wasnt as straight forward as planned – the additonal ‘gaps’ in the bookshelf paying off to allow the ‘sturdy’ coax of the ATU to the 7300 to be in place. I did attempt mounting directly underneath, but it was becoming more of a mess than it already is. With a rejig and some persusasion, the ATU was in place and functioning correctly.
I started out on FT8 – there was plenty of traffic on top-band and managed several QSO’s as well as seeing how well the antenna was doing being matched to 160M with 50W of power.
FT8 on 160M (80m added in for testing)
Having enjoyed a pleasent evening out and the fresh air of Poole Harbour, I resumed my work in the shack and started WSPR transmissions on 160M with 1W of power. I’ve been doing 10M during the day, and its been geat to see the data of how the propergation really varies and almost to immediate effect when the sun goes down, so it would be good to see the inverse of that. I was not to be dissapointed !
WSPR 160M with 1W of power
Suffice to say, the ATU was doing a great job in matching the antenna and still with a decent amount of power being transmitted on WSPR, the MFJ reported between .5 and .7W
MFJ ATU working well on WSPR with 1W
Needless to say, as someone who enjoys digital modes and analysis of the data produced, its great to have this added functionality back. With the steady stream of WSPR data becoming available I’m looking forward to updating the webtechnologies site ready for early next year, so the MFJ will be staying for the foreseeable future ! Yes it is worth it !
Sundays weather took a turn for a worse, the best part of the day was used to enjoy some time out the shack and with my XYL. We headed off to the New Forest then to Milford on Sea. In the Bongo I have the Kenwood TM-D710GE which I use for APRS on 2M and scan the other bands, GB3IW used to be on 2M, with amazing coverage, being able to reach as far east as Shoreham/Worthing, it was a good way to make /M and /P contacts (as you’ll see in other posts on the blog). I tried out to reach IW from Milford-on-Sea, but no luck, where ever the repeater is now, its a former shadow of its once great coverage, which probably led to its demise thanks to abuse.
We headed back home and whilst there was spatters of rain, there was a time to get out before the sun went down to make some small progress on the satellite antennas.
I removed the previous horizontal beam and replaced it with the one supplied in the kit. I was careful enough, as the vertical holders are only fibreglass, and it would be unwise to knock them and suffer any undue damage! As I had already had a full day, and the next step would be to start erecting the antenna and horizontal fetelling, decided to call it a day, happy at least that the anteannas are in there temmporary mount.
I’m hoping for some good weather today to at least make sure I can locate the coax and get things in place. My son is due to visit this week, so I will put the antenna vertical with him the first time at least, then I will have a better idea of the effort and how easy it is to get up.
I finished the day with a nice meal of roast lamb, which on a cold, wet and rather miserable evening, was a welcome break.
GB3SU + M0DQO 70cm contact
Further to my lack of 70cm contacts via GB3IW, I had a scan thru the bands at the QTH on the IC9700 today (Monday 13/11/23), I was glad to find GB3SU in Southampton. I monitored for a while and was pleased to hear a call out from M0DQO, who was operating portable on his way to work. It was a good QSO and learned about Chris’s setup, which worked really well being /M via Bluetooth controlled PTT Headset. It was a good start to the day and will put the repeater in the D710 to listen to when I’m out and about in the New Forest or en-route to Guildford.
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 OK1DNTMMSTV working well with the IC705enjoying 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.
RT73 and donkeyhaving a nibble on the grass
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 logbeta model manual logadding 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 !
Not much happening on the amateur radio front I’m afraid. I did have some very good SSTV QSO’s the other day 80M – quite a few in fact ! With that I have been quite poorly with a cough and a cold, hence the COVONIA which has come to the rescue !
I’ve had a large amount of medicine and allot of sleep which seems to have restored me to at least being able to type up my blog. I was determined to get the BONGO going as well, as the fuel filter had arrived. It took a bit of labouring to get the fuel-filter to fit back on the chassis, but sure enough the bongo is now back in action !
Webtechnologies site updates
Other than doing hands-on radio I made some updates the webtechnologies website which captures all the WSPR transmission reception reports. Basically I’ve made it much simpler and requiring allot less maintenance, with better integration into Git with a fully functional CI/CD pipeline. I had this in place already, but it wasn’t quite perfect, so with a chance to sort it out, I’ve reduced the features (FAX pics and KIWI SDR) and kept it to just WSPR reports and Weather from the the local weather station here at the QTH. This will allow me to develop new features for the site as time allows..
Next POTA
With the Bongo back in operation, i’m hoping to get back out and do another POTA activation soon. I still have a pretty full February now but am determined to get out and on the air, hopefully this time with a UK Antennas 40m multiband end fed. I’m not sure I can squeeze POTA in this month due to commitments, but will see how things work out, rest assured, I will be looking to get back out and on the air thou !
Thats all for this week, please keep well and thanks for reading the blog.
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 !
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 🙂
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.
