Stuart G4WCP – Taplin Centre January 28th 2015


Stuart G4WCP opening the evening. An enthusiastic digital mode op!















I had been in contact with Stuart for some weeks prior to the talk and it became quite clear early on that he is not only enthusiastic and knowledgeable about amateur digital modes he is also a generous and kind fellow as well.

We spoke at considerable length prior to the meet and covered various topics on the digital modes and antennas. Stuart (G4WCP) uses a non-resonant T2FD at his QTH in Brighton following inspiration taken from John Heys (G3BDQ), his teacher and mentor, many years ago. It probably comes as no surprise then that I picked up quite a lot of useful info about the various digital data modes, some of which I had never heard of before and I considered myself, quite wrongly, to know a fair bit about most things digi .. at least until Stuart chipped in with plenty of responses to my questions and offered various items of advice.

A couple of weeks prior to Stuart’s presentation at the Taplin Centre I was concerned by the possibility that the recent bad weather may have taken its toll on the club antenna again. As unlikely as this was given the recently improved re-installation of the doublet last year by Phil (G3MGQ) and Antony (G4CUS), I felt as though I could not leave it to chance without checking first. Fortunately, Leon (G1HSM) very kindly agreed to pay the site a visit for a visual inspection which revealed that everything looked in order and the evening was set to go ahead as planned.

It was a pleasure to meet Stuart for the first time having only communicated with him previously via email, and he certainly came well prepared with a Yaesu 817/LDG Tuner/Signalink ‘stack’, a tiny 8 inch tall HF setup which must be a dream to use in the field or while on QRP ops in a small space at home. Sadly, due to reasons beyond our control at the end of the PowerPoint presentation, and despite the best efforts of Phil (G3MGQ) and Paul (M6PWD), who quick-fixed a cable-tie to a PL coupler in order to hook up the balanced feeder, a source of EMI looked likely to blame as Stuart’s mouse sadly locked up intermittently while connected to the TV making the final hands-on demonstration a no-go.

Improvised balun devised by Martin, G0DCG, who helped Stuart get hooked up in a jiffy. Phil G3MGQ and Paul M6PWD also quickly assisted with the coupler fix.


















Despite the sudden onset of EMI gremlins, Stuart persevered and managed to show us his digital mode setup on a laptop at the end of the evening but not before he gave his excellent talk and PowerPoint presentation which provided a useful look at his views on the subject in this very popular segment of amateur radio operating.

During the evening Stuart covered many digital modes including the JT’s, Opera, PSK, and one of his favourites, WSPR (Whisper) meaning “Weak Signal Propagation Reporter”. This is an ultra narrow-band digital mode occupying just 6Hz of bandwidth and features lossless compression using continuous phase 4-FSK modulation. One remarkable feature thanks to WSPR’s inherent efficiency is that it is capable of decoding signals with a S/N as low as -28 dB with 2500 Hz bandwidth making it more than adequately equipped for weak signal work. WSPR was originally written and released by Joe Taylor, K1JT in 2008 and has since become open source software (free to use and modify) and gained a strong following thanks to its efficiency in sending communications in the worst conditions possible, namely the operators call sign, 4 digit locator and dBm.

Personally speaking I used PSK for some time when I first started getting my feet wet with digital modes, and found it reasonably useful for discovering propagation information using the PSKreporter website. WSPR has a similar web based system (free registration required) which can be found at where stations that are connected to the Internet can send their reception reports directly to the site so that real-time propagation observations can be conducted quickly and easily, making the process of understanding weak signal propagation considerably easier.

Stuart also spoke about the controversial Winlink/Winmor system which is a method of sending email via RF. Stuart introduced this to me recently and often fires off email using HB9AK on 10.144.400 though it should be noted that the system is only legally operable by licenced amateurs should you happen to be interested in giving it a try. Winlink is a very valuable system in times of emergency allowing text communication to be sent via RF to the Internet and onward to its destination from any location on the planet where you are able to hear one of the many Winlink ‘email gateways’ such as the popular HB9AK which is located in Berne.

I have used Winlink using the free RMS Express software to send email and it does work very well indeed.

To Stuart’s credit for giving a great talk under the circumstances without a live demo, and everyone present for their assistance, I extend my thanks to all. It was an interesting evening listening to someone both passionate and knowledgeable about digital modes, and sincerely hope that at some point in the future Stuart will return to give us another insightful talk at the club.

Update: Stuart has since been in touch and is keen to operate G6HH using digi-modes from the club in the future and provide further insights into the practical side of digital mode operating. Something to look out for!

G3MGQ’s Month on the Air February 2015

GB3EB goes offline due to fire at site

logo_rilgesNews came through via various sources over the last couple of days including a quick report from Paul M6PWD who spoke to Gordon (M3HXY) on GB3HE earlier today.

Sadly, a fire broke out at the St. Lukes Church site where GB3EB is located in Eastbourne and as such the repeater will obviously be offline until repairs and further arrangements are made to re-instate the repeater.

According to Dave G8PUO at RILGES who run the repeater GB3EB will go off-air Saturday 17th January and will also sadly mean that the planned installation of the new D-Star repeater GB7ES will be put on hold until the repair work at the Church has been completed in a few months time.

The repeater hardware itself is quite intact though will of course have to be removed for inspection and testing. Initial time-frames for the building repair works to be completed is expected to be at least three months.

Dave already has discussion underway with regards to the options available for the repeaters and has promised an update as soon as a route forward for them is found.

Best wishes go to Dave and the working party on Saturday who look as though they have quite a tricky job on their hands.

Stuart G4WCP to give talk on Digital Amateur Radio

One of the clubs Brighton based members, Stuart (G4WCP) is going to give the club an interesting talk on the subject of “Personal Aspects of Digital Amateur Radio” on the 28th January 2015 at the  Taplin Centre. Doors will be opening at 7.30pm and should prove to be both an interesting and education evening as Stuart has been an avid digital radio operator for some years, operating QRP from his Brighton-based QTH using a selection of antennas including a 25m sloper T2FD.

According to Stuart the evening will also have some ‘hands-on’ for members and will no doubt be an enjoyable evening. See you there!

Update:  Read the report for Stuarts fine presentation on Digital Amateur Radio.

New Licences – Regional Secondary Locator in Callsign Error

As advised in the Licensing Update in the January 2015 issue of Vital Spark, new Licences are now being issued by Ofcom with those changes incorporated in the Licence Document. However, by error, some of the Full & Foundation Licences recently issued to stations whose main address is in England show the Regional Secondary Locator “E” in their callsign.

Ofcom have now confirmed this to be a mistake –your callsign is unchanged. The use of the other RSL’s remains optional, with only Intermediate Licences including the RSL “E” for England their callsign. (see
