GB3BN net 8pm 26th MARCH – A Summary – thankyou!

On the evening of what should have been the spring junk sale 2020, postponed due to COVID-19, we had a net on GB3BN with 23 stations joining. Now, more than ever, communication is important . We did that in spades.

I thoroughly enjoyed running the net. It was fantastic to combine getting on the radio and having a club meeting. Looking back, we really did that using the technology we love. At 8pm, I didn’t know that would happen. All I had was a beer and the radio by my side. By 10:30pm I had a list of 22 callsigns (with ticks against them, finally, to indicate signout) and it really felt like the end of a normal club meeting, or even better because everyone took part and contributed. This virus will not stop us.

Operating procedures were first class. Everyone. No exception. New M7 operators/callsigns? Flawless.

Because it was so productive, I thought I’d try and capture a few points.

Firstly, it was wonderful to be able to collectively say THANKYOU to our magnificent NHS together, on air, using BN’s huge coverage area.


  • In these uncertain times, this net is a place where we can all gather on 2nd and 4th Thursdays where we would have had a face to face club meeting. To ‘check in’ if you like.
  • Following on from the BATC’s support for online meetings and their offer of support for clubs, it is clear they are something RADARC needs to pursue. In particular, a number of members enjoyed Noel G8GTZ’s QO100 talk.
  • Lots of practical tips for surviving the ‘lockdown’.
  • Finding out about other nets (eg. G1RAF has a net on GB3TU 433.225MHz: 12:00 and 19:00 daily).
  • Discussion about new conferencing technologies: eg. zoom, discord.
  • Propagation news: HF, VHF. There are some signs Sporadic E is starting on the high HF bands and 50Mhz. The Poldhu net on 80m was in fine fettle.
  • Virtual sharing of beer and biscuits (Jammie Dodgers no less) in the finest Reading tradition. (There should be bulbs in there also – gardening did feature).
  • Updates on construction projects – reports of exploding tantalum capacitors.
  • The trials of home working.
  • Clarification on how the local repeaters work with CTCSS. You get a ‘T’ in morse if you’re running CTCSS, ‘K’ otherwise. Soon, I think, you’ll need to run CTCSS. see for details.
  • Our ‘YouTube’ channel with videos of previous talks (thanks to James 2E0JPM) is
  • Loads more. If I’ve missed anything you would like included here then please let me know.

Thankyou for a special evening.

Apologies for getting any callsigns wrong. Now you can see why. The raw material for this post.



The RSGB has basic information on using repeaters here:-

Accessing repeaters is detailed here:-

Table 1 below shows the closest repeaters to where the club meets. If you live elsewhere you can go to and enter your postcode to find out your grid location. Then go to and enter your grid location and click on [km] to filter by distance.

There is a useful app called ‘RepeaterBook’ for Android and Apple devices which uses your location and shows the nearest repeaters to you of the selected type.

One thing which has caught me out is that new repeaters are required to support CTCSS however they often also support the 1750Hz tone burst. When CTCSS is used to access them then they are also required to output CTCSS. The mistake that I made was configuring the radio with the CTCSS tone for send/receive. I was missing some transmissions and the radio was indicating a CTCSS mismatch. This might have just been the the regular beacon they transmit but it might have been someone talking which used the tone burst to access. Switching my Yaesu from ‘T SQL’ to ‘T ENC’ resolved this issue.

Logging & QSL

I use for looking up callsigns as it seems very popular and it is nice to see a bit of information about the person you are speaking to in addition to being an additional check you have recorded their callsign correctly.
If you sign up you should be able to get someone else to add your callsign to the database. If that doesn’t seem to work or you prefer you can go onto their forum and provide basic information and someone there will add it for you. It took a couple of days for someone to update my callsign so that it was associated with myself correctly. Once it is all setup you can update some information about yourself and use the online logbook.
If you prefer windows software then I have played with ‘log4om’ which seems pretty good. If you want it to automatically post to then you need to subscribe to at least the xml logbook package which is around $30/year. Personally I just use but if you are using HF and have a link to the computer so log4of can read the radio settings and are making a few contacts then I can certainly see the benefit in it.

Although using the logbook you can request confirmation you don’t get any form of QSL card. The RSGB offers a bureau service ( but a lot of people seem to use an electronic version like Basic access is free but you can pay for various additions such as bronze membership which enables you to upload your own custom card design plus additional benefits.

Tom M0LTE Suggested
“You mention logging, which reminded me – for anyone interested in logging, might I also suggest Cloudlog, a modern web app fit for this decade, which has just been launched as an inexpensive subscription service (previously your only option was to install it on a webserver of your own – you can still do that for free but it’s hardly worth the hassle for £4/month).”

Other Links

There are various web based SDR’s that you can use to listen on different bands at various points around the world. is a very good list and the Farnham one can be accessed at is a system where you can use a PC or an app on a mobile phone to link to other Echolink devices. You do need to upload your Ofcom certificate to get the account validated but I found this was very quick. Other devices can be other users, groups or even repeaters.

Junk Sale (26th March) postponed

Dear Members,

For reasons I am sure you can guess, we have decided to postpone the junk sale scheduled for the 26th March. As you know the room is always packed, and with various things changing hands it would prevent a high risk of spreading the virus. We are sorry about this and I myself am disappointed, but, we are hoping to be able to reschedule it later in the early summer.
Unfortunately the lectures planned for April will also be postponed for similar reasons, but again we hope to run the same lectures later in the year or early next year.
As we are radio amateurs, we hope to make use of this to stay in contact and socialise over the air waves, so we will be announcing at net to take place at the time when we would usually have a  ‘pass out’ so at least we can still chew rag!

We will send out regular emails with any further news.

Take care, and good health to all of you, do keep in touch.
