So after a rather nice lay-in I headed off to hengistbury head with Sweety, Kenwood TH-D7 & VC-1, Baofeng UV-5R and with the IC-705 setup to receive and upload photos at the QTH.
It was a lovely start to the day with great weather. Coming later in the day sure does get busy down there, but it was nice to see so many people out and about.
It was great that everything fitted nicely into a compact box, which I carried on a backpack with some water. I think i will bring a small box/bowl for sweaty next time as well as some ‘treats’.
Here is setup video, apologies for the windy noise, goes with the area and using a phone. My bag tried to make an escape as well, but i caught it ok 🙂
The other reason i come to HH is that it has enough hills and a decent length walk to give me some decent exercise, i don’t mind saying my knees and legs really feel it, but I’m glad to push myself that little bit and am rewarded with some great views and operating conditions.
We reached the far-end of HH (from the car park perspective) and I set about checking the results of the SSTV` broadcasts I had made, unusually I couldn’t see any at all ! Not even static.
I packed the Kenwood equipment away and kept the UV5R in my pocket for any simplex contacts. I called CQ on 2m (145.500) and had a great QSO with G3TOI who was working thu his great 2M VHF home-brew antenna. We had made contact before but when i was at home on the IC-705 and Diamond X-30, it was great to make a simplex contact on 5W /P.
Coming home it was clear what had occurred ! I must of knocked the transceiver when leaving and it was set to 144.375 for receive – doh ! Anyhow, glad it was a simple issue rather than anything untoward.
I headed back out in the afternoon as XYL was at a training course, which gave me 2 hours to do some local tests. I headed out to West Howe and made a good contact back to the QTH
Whilst not P5 quality, i can at least see the picture and where I am, so I’d say that was pretty good on 5W and about 2-3 miles from the QTH.
I then headed off to Poole Harbour, sadly (and predictably) no SSTV contacts, i think 5W and the dip is asking a bit too much, however i did have a great QSO via the GB3IW repeater on the UV-5R
Having driven around west of Poole to higher ground, i could still not make contacts, it was interesting trying tho. In some locations i could still make out the GB3IW repeater as well, and this well in-land. My first good retest was at the Kwik-Fit at Bear Cross.
The image came out pretty well from about 2.2 miles away.
I then continued driving towards Hurn and the final test location of Ringwood.
The results from Hurn are very good, a P5 image quality from about 2-3 miles away. Heading to Ringwood did get a receive, but only static in terms of the picture. As I know where it was taken I can make out features, but with no call sign and clear image, its not useful as a radio amateur.
Results 2nd time out with the TH-07 and UV-5R was much better than in the morning now that the IC-705 was in tune to the /P transmit frequency. Optimal results seem to be around 2-3 miles currently based on the reception of images.
I think the best/quickest upgrade will be swapping out the TH-07 stock rubber duck antenna and returning to the locations where I had static to see if there is any improvement in reception from the QTH.
So aside amateur radio, my other ‘interests’ is model railways. My fellow rail enthusiast are building this small layout.
Whilst that hasn’t been taking all of my time, it has taken a fair chunk in trying to find all my N-Gauge track and equipment. I have how ever been very busy in and around the shack !
I have got the VC-H1 working. Getting all the cables from around the world (Korea, Portugal, USA) was quite an adventure and took a fair amount of ‘google-fu’ to source. I have a number of videos, but this one is probably of the most interest where I done a field test and the results.
The broadcasts from the park resulted in complete susses of received images from my QTH about 1 mile away.
I was using a Baofeng with 5W and other tests around IO90BS really showed how the height/hills in the town effected the reception. I think my best chances for long-distance are away from the SE direction where I am behind a steep hill. I will spend some time and do some VHF reception modelling in the coming weeks.
So with the 2nd year of my Part-Time MSc coming up time was limited to get the ‘shack’ (aka Home office) into some semblance of tidy. Getting a Radio Shack tidy isn’t just making it ‘look’ tidy, its about getting RF right, every thing that requires ferrietes to have them and good cable management, all whilst be useable, manageable and allowing for further development of other projects.
I started outside and installed good coax, as well as a general tidy up around the antennas. I then installed a thru-window panel, allowing the feed lines to be tidy into the shack. From there I took out all the transceivers, receivers and other radio devices. The bulk of the work was done over the weekend as it took a fair amount of time.
As you can see from ‘Day 1’ there was allot to do just to things in place.
I’m now have installed the transceivers onto the bonding and am looking forward to test out the bonding/grounding results.
My next step will be to get my Windows computer re-installed with the necessary chokes and filters to operate well with the computer with no effects from RFI. When that is installed I should have a good idea of how to tidy the cables best as described in the Grounding and Bonding book.
With re-opening of the Poole Amateur Radio Society and enjoying regular on Thursday evenings, I’m getting more out of my radio and understand them than ever. Its great to have good and productive conversations with fellow hams, although the conversation sometimes does drift to non-radio activities, I have been grateful to receive several courgettes which XYL Monica made into a lovely meal for me !
The club is having a field day event away from the QRM of the urban environment. I’ve very excited to be going with my IC-705 and Alexloop ham-pack. I got a new ‘mast’ for the antenna, as you can see here.
Results are really encouraging !
With all the equipment that will be required for the field day I got a hand cart. Sweetly and I had a great time testing it out.
So I’ve been super busy, but very happy with all with all the amateur radio activities. It will be harder after September to spend weekends like this as I start my MSc Computing Research year in earnest, but undoubtedly the model trains and amateur radio will make a welcome break when time allows me to do so.
Having got some much needed help in the evening after work, my friend and I erected the 40ft mast. This went pretty well between the two of us, and resulted in a nice vertical mast.
As this was done after work on a Friday evening, we headed in for a lovely meal prepared by XYL Monica.
The next day the weather was unusually good and a day of productive antenna erection could commence ! Having guyed the mast the previous evening, my intention was to get the 80/40m dipole attached to the top with the feedline going up the mast. However, after several attempts I was getting this result.
The tilt base from Barenco really came into its own, doing this any other way would of been difficult, not to say incredibly frustrating boarding on insanity.
After several breaks to contemplate a solution I figured on using the hardware I had but changing the antenna. Thankfully I have a UK Antenna 80m end fed in storage, so I lowered the bent mast to a more sturdy but decent height and used another of the fibreglass poles I had. Feeding the end fed thru this I was able to get it a good height and not as intrusive as when i had two fibre glass poles going into the front garden. I ended up with a ‘sloping L’ configuration rotated 90 degrees from the feed point.
The above video makes this much clearer and you can see the height of the initial mast and fibreglass pole which support the 80m wire.
The SWR results across 80m are impressive and I attached to my IC-705 to test, the reception was fantastic.
The multi band was resonant on every frequency stated, so I will be really looking forward to trying this antenna out on a more frequent basis
40m gave impressive S.W.R. readings as well, I am only planning to use QRP levels, with the occasionally 50W from the TS620S. I am very excited to get this antenna into the Kenwood Ts690S as its a super-het receiver with many filters in it. Thats not to say the IC-7300 wont be the main transceiver any more, but will be fun to see the difference between the two.
So what a busy weekend ! Having been to Poole Radio club this week and catching up with an fellow member received the necessary advice on how to best install my 80m/40m dipole in terms of location in my QTH.
I then set about building the mast to get the dipole up, its a series of videos, so i put them here in order.
So TL/DR i didnt make all the progress I wanted, having taken care of my health and not getting too tired, i have ordered a new tilt base for the 33ft mast.
The Barenco looks a good bit of piece for the price, if it allows me to tilt a 33ft mast up with ease, worth every penny ! For sure there will be a decent video and review when its installed.
With that the Poole Radio Society on 2M I set about getting my 2M equipment setup. I tried to use the Retevis RT90 but wasnt having much luck with programming and operating it. I got the RT90 as its a good DMR radio and works with my Pi hotspot, but for monday i just needed something simple to use for the 2M net, so i pulled my IC-2200H out and done a factory rest on it.
I was soon on the air with my Yagi and making a great local contact. I couldnt reach the 3rd contact in the QSO on the Isle Of Wight, so over night considered how I would best address this for the monday night net.
I was really impressed that i got the antenna up in less than ideal weather (rain, wind) and had positive S.W.R. readings
I then set about calling CQ on the 2m calling frequency of 145.500 and was able to make a number of contacts thruout the day.
I was really pleased that I was making and having really good conversations with seasoned fellow hams in the area, especially another member of Poole Amateur Radio Society remembered me which was great !
Feeling ambitious, i then set about looking for repeaters. Our local repeater is no-more for at least the short term and no real indication of if/when GB3PBR will return. GB3JB appeared to be just in reach, and i setup the 2200H with the respective frequencies and tones to access it, sure enough I was rewarded with the ‘pips’ that I could reach the repeater !
I monitored thruout the day and enjoyed several really good QSO’s via the repeater, which varied to just down the road (ended up with a simplex conversation off the repeater) to many miles away beyond Dorchester !
I continued to add a choke filter and Y-split to the 2200H so i can use the Yagi and J-Pole should I so wish to.
It has been an excellent weekend on the radio, the shack still isnt as tidy as I would like it, but its getting plenty of QSO and 2m action thats for sure ! I’m looking forward to next week and progressing the 40m/80m dipole some more, it will be excellent to be back on both frequencies again.
Many thanks for all of those that had telephony QSO’s with me this weekend and setting up/checking and giving me loads of info about 2 meter operation in the locality, it really has been great to have a ‘rag chew’ with local operators again.
Despite several operators infringing on the SSTV calling frequency of 14.230 and poor conditions I wasnt put off calling CQ. Whilst I didnt get a response, i was amazed to see that I was received at about a P3/P2 clarity by VE1DBM.
I’ve had several great QSO’ s on SSTV around Europe, I’m really happy with getting on with this ‘new to me’ method of making contacts. I particularly enjoy making new photos and sending them out. I have received some, which I though a little risky in terms of nudity, but still good quality pictures and well received by the Wellbrook Antenna in poor conditions.
I’m getting my 2m transceiver setup over the weekend, and will try and connect it back up to the computer, i’d love to try SSTV on 2M with a Yagi !
I have a few more write ups to do on learning, local nets, but that will be later in the week.
Having owned the IC-705 for quite some months this was my first time to take it portable. With the weather looking slightly dodgy our group of friends headed to Boulderwood in the New Forest.
Our risk taking with the weather was rewarded with a fantastic, albeit slightly cooler than of late, evening in the New Forest.
It was great to go with a friend as although the setup was minimal a helping hand was greatly appreciated. I attached my Alexloop Ham Pack antenna to my Buddipole mast with a bungee which done an excellent job of keeping it secure
I brought along a couple of fold up tables, one for the ladies ot have their pic-nic on the other for me to setup my radio. I started with just the IC-705 first and tuned to 20m. The quality of the signals away from the QRM of my QTH was simply amazing.
I did try to reply to the CQ calls, but couldnt get a response this time, but was nethertheless glad to just be trying.
Operating the the Alexloop Ham pack was everything it should be, really easy to tune into the frequency. I was getting SWR of 1.3 to 2 on all the frequencies i tuned. I dare say I could get better as I get more expericned with it, but the gauge on it is fantastic.
As seen in the picture above the LED on the tuning unit shows the power/matching of the antenna to the transceiver. I also used the SWR meter on the IC705. I did bring along my rigexpert (HF) but didnt need it in the end.
Having run 5W on the internal batttery, i then switched to a Lifo battery and got the full 10W portable. My connections to the battery need improvement, but are functional.
I was able to test FT8, and received plenty of signals from around the world. I explained to my friend how FT8 works and our signals on PSKReporter. It was amazing how far we was getting out on 10W and the Alexloop !
I was unable to make a contact, but I was still gald to be getting out. I need to learn how to adjust the volume control on my linux laptop, as the signal was overloading, i suspect i missed some DX/RX opputnities.
Next we tried WSPR – with the portable battery it was no problem to keep going. I checked the database and my own site and could see that we was getting out nicely, albeit with 10W which is probably the most power I have ever used on WSPR.
I must rememer to update my callsign for Mobile operation next time as I only changed it later in WSJT-X.
After digital modes and with the sun / grey line coming in I made one more try on telephony just calling CQ, but alas no responses. I dont feel disappointed, i had limited time and wanted to make sure we got back home all feeling well and having an enjoyable evening, so packed up. Again having a friend help was great, everything was put away with no damage and easily into my camper van.
This was a great first experience of being portable. I really enjoyed it and am sure to keep on trying and will probably make Boudlerwood my goto place. If you ever see me there, dont be shy and am always happy to talk to people who are interested.
This has really added so much more to this already amazing hobby. I can thorougly recommend portable operation !
Have had a great weekend on SSTV on 20m. Thunderstorms are incoming to QTH in IO90BS so have taken the antenna down for now, but will be back once they pass.
I’ve been able to setup an automated upload. The site is here and can also be found on the tabs of the main site. I’ve also subscribed to World SSTV cams, so other amateur radio users can see their reception at my site easily as well.
I’ll take you thru how I setup the Windows and Linux side.
On the Windows host I download and installed KE5RS FTP Widget which is available free with registration info of call/sign location. Run the setup and let it install in the default locations.
The next step on the windows host is to create the local SSTV directory – this is in *addition* to the SSTV images MMSSTV uses.
I opened a command prompt (Start / Run / CMD) and typed the following
I created a shortcut to the desktop for FTP Widget. This is useful as I found running it as administrator overcome any file permissions issues on the local side. This probably due to the mechanism and file permission settings that MMSTV uses to duplicate the files, running as administrator fixed this.
I then run as administrator from the desktop.
Now if you have not used FTP in the past the cocent of local and remote paths will be new, and each FTP client will have its own interpretation of how to set it. Usually the remote system is a Linux/Unix system and the actual full remote path is typically /home/sstvimagesusename/images but the FTP Widget takes the login from the FTP Server and uses the short path name, in this case images.
You’ll need to set the local drive to the one created in the DOS prompt earlier. In image name properties, only change the name if you really must, this is important as the crude template i will provide below depends on the filenames matching. You’ll also want to keep the Image history to what ever you iike, by default its 3, I upped it to 12 as this gives a better log of the images.
On the Linux side I’m using vsftpd. I dont mind saying that running FTP in 2021 is slightly unusual, most file transfers are done over SSH / SFTP more recently, but FTP still has its purposes.
I would suggest running vsftpd as it has options for TLS/SSL as well as chrooting. ‘chrooting’ is a method of ‘jailing’ a user to their own location, so in the worst case the credentials are discovered, the only space they can easily access is that of their own home directory, not the ntire OS filesystem (old FTPs that allowed system access could easily be used to accessing /var/log/ and from there discovering other usernames and ‘brute forcing’ the credentials).
Here is the full example vfstpd.conf , you dont need all of this, but from the default you can see the deltas.
# Example config file /etc/vsftpd.conf
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.

Be sure to keep a log of the password, of course you can always reset it, but it makes setting the FTP Widget properties easier.
With the Unix side complete, its time to finish off the settings for the FTP Widget and SSTV.
Follow the settings given above, putting in your FTP address, either the hostname or IP address. i.e. myftpserver.bob52.com, <n>.<n>.<n>.<n>. You don’t ned to put in the URI ( ftp:// ) .
The next step is to configure MMSTV to copy the received files into the FTP SSTVPics directory.
In SSTV goto the History tab and right click the image, select ‘auto copy to another folder’ and assign the folder name to the SSTV c:\sstvimages directory.
With that your received files will now not only be stored locally, they will be automatically FTP’d to your webserver ! If everything goes well, you’ll end up with a page whereby other SSTV users can see how their images are being received and a nice catalogue of recent images for yourself.
Recently I started to experiment with SSTV (again) on my IC7300 and Windows desktop.
I’ve not been able to get it to work with the band select, but the audio in, out and importantly PTT fine. I saved the main SSTV calling frequency to my IC7300 (14.2300 USB) and just recall that when i want to use SSTV.
I’ve learned to use, but not to rely on, other KiwiSDRs and other sites that scan SSTV images. Most of the time I am seeing one side of the QSO on the remote sites, a good example of this is the slowscan tv site in the Netherlands.
The conditions have been pretty bad lately, but once in a while I get a really good QSO via SSTV, an example from today below with IV3VBM. I’m using 50W into a 6BTV with conditions being reported as ‘poor’
I am really enjoying SSTV – during the day and overnight I can leave MMSSTV running to receive great pictures, and also look back to see how the propagation has varied. I was amazed to receive these transmissions from the US last night !
As you can see the propergation is clear to see as the quality of the pictures vary.
I’m now working out how to automate the upload and ‘most recent’ pictures to the hamradio website, it shouldnt take me long, but as every life is keeping me very busy !
I hope this encourages other users to try out SSTV, its great way of having a digital QSO with personalized content, so why not give it a go.
Where has the year gone, or more accurately where did June go ? Well, having been busy with work, uni and mentoring the month flew by. WIth bad weather alot of the weekends it meant I couldnt get alot of what I wanted to do done, and the time I had was limited. The good news is that alot of my University work for 2020-21 year is complete, I’m just waiting for grades to be finalized. I’ve changed jobs and am glad to say my new role is more suited to me, so Im really enjoying work. I’ve also had a great time mentoring undergrads the past few months, but has made me very busy, but very rewarding – but heres the good news – this weekend I got a number of things on my ‘ham radio’ to-do list done.
Firstly, I got my IC-705 working in the garden on the Alex-Loop ham-pack. It went really well, although setup wasnt as good as I thought it should be. I’ll do a longer more in-depth write up, but needless to say initial operating was fun and exciting.
Recently and friend and I mowed the garden, as I had told our gardener to not worry about it for the moment due to the movement of tents and radio equipment out. With all the rain and sunshine the grass grew at a proflific rate ! I first borrowed a friends lawnmower, then got a cheap electric one from amazon that would do the job. I’m glad to say that having mown the antenna area with all the radials down the majority of the radials have stayed down.
I will continue to mow the grass and keep it short, then look at adding more radials with better wire-pins (I have been using plastic ones). I still have some more work to do on the 6BTV to add 17M to it, but hopefully the weather will hold at the weekend, in the mean time I have been enjoying FT8 and SWL, making interesting contacts and getting ever closer to the DX100 award.
