Listen to radio amateurs without a radio!
Thanks to the internet, it’s possible to listen on amateur radio frequencies without a special short wave receiver.
There are many WebSDR (Software-Defined Radio) receivers connected to the internet, allowing multiple users to listen simultaneously.
A list of WebSDR receivers and links to them is at http://www.websdr.org/
To use WebSDR…
- Navigate to a receiver like Hack Green, Cheshire (one of the closest WebSDRs to Birmingham) or KFS WebSDR in California (where you can listen in to the US amateurs).
- Once on a WebSDR site, enable ‘allow keyboard’, which permits you to tune the receiver using mouse wheel or keyboard arrows.
- You may have to enable audio settings on your browser – see the advice on each webSDR site; eg for listening to Hack Green using Chrome: Click the Lock in the address bar of your Chrome browser. Click Site Settings. Under Sound, select Allow.
- Select the band you want to listen on – you will find most stations on 80, 40 and 20 meters, in the frequency ranges in the table below.
- When listening on 80 and 40 meters, select LSB (lower side band); when listening on 20 meters, select USB (upper side band).
- Once you hear a station, it may sound like ‘Donald Duck’ – tune slowly and the voices will become clear
- Once you become proficient at tuning in stations, try some of the other receiver functions – e.g. narrow IF bandwidth and IF passband can be used to reduce interference.
Over the next few months, you can expect the following radio conditions:
| Amateur band
(meters) |
For SSB (voice) tune these frequencies and select LSB or USB as indicated | Expected coverage if listening to Hack Green
(More detail on propogation predictions here)
|
| 80m | 3700-3800 LSB | Daytime – UK; Evening – UK and continental Europe |
| 40m | 7100-7200 LSB | Daytime – continental Europe (sometimes UK); Evening – Europe, and occasionally further afield |
| 20m | 14150-14300 USB | Daytime – Europe; Evening – Europe and often further afield |
CALL SIGNS
You can identify the countries from which stations are operating by comparing their call sign prefix (the first one or two letters/numbers) with those on the list of international call sign prefixes e.g. the Wythall Radio Club call sign is G4WAC – G means the station is in England.
Q CODES AND OTHER SHORTHAND YOU MAY HEAR
You may hear the following…
CQ, CQ – I am calling for a contact; please reply to me
DX – long distance (normally, outside the operator’s continent)
QRZ? – is anyone there?
QTH – location of the station
QRM – interference on the signal
QSB – fading on the signal
QSL – confirmation of the contact or information passed
73s – best wishes and goodbye
GAINING AN AMATEUR RADIO LICENCE
The ‘Foundation licence’ is not difficult to obtain. There is some simple electronics and radio operating to study. You can find details of the licence levels and courses on the Wythall Radio Club web site and there is more information at the RSGB.


Visitors welcome at Wythall Radio Club’s famous ‘Plug and Play’ event on Saturday 9th Sept. between 10 and 3.
You’ll see vehicles, antenna masts and flags – that’s where we are.
The open evening is on Tuesday 5th Sept. from 8-9pm in the Darts Room, on the ground floor of Wythall House. Follow the signs.



It’s a commonly used idea in NFD- to have a longer antenna overnight for the low bands and shorten it to make the antenna more efficient during the day on the higher bands. For QRP work my junk box phono connectors will hopefully suffice” 









He helped out at all of the club ham rallies and was often to be found providing sustenance at club portable events such as field days, plug and play, special event stations and the summer BBQs. The club was able to show Jim how much we appreciated his enthusiasm for club events by naming a trophy after him last year. He was also very supportive through some difficult times at the club. Jim’s involvement with radio started in the CB days of the 1980’s and Jim always had the odd CB radio around although I don’t believe he used it very often.

Practising with this key I found I preferred its feel to my Hi-Mound HK702 key. Perhaps I now had the right gear to do something about my long held ambition. Being of an older generation I have a real empathy with real knobs and switches, touch screens and the endless menu options of modern rigs has just never appealed to me. Fat arthritic fingers have never been best tools to use on touch screens.
Having only one antenna and no wish to erect a second one, the problem to be solved now was how to connect a second radio up to it. At first I looked for a coaxial transfer switch as shown in the schematic below. As the switch is turned through 90 degrees , Tx 1 port is disconnected from the antenna port and connected to a dummy load port. At the same time Tx 2 port is disconnected from the dummy load port and connected to the antenna port: foolproof and ensures each transmitter is connected to an antenna or a dummy load, thus avoiding transmitting into an open circuit. Such transfer switches are common in commercial broadcasting or communication systems but are very expensive, so that wasn’t an option.
Looking through my junk boxes I found a couple of coaxial switches which might provide a cheap solution. One was a 4 way coaxial switch and the other a three way coaxial switch (see PHOTO below)

Beaver Scouts from Wythall chatted with radio amateurs on the west coast of the USA during their communications evening.
The QSOs were hosted by Les 2E0LRV from Wythall Radio Club (photo left). He used a Yeasu FT8800 mobile radio with a patch lead as an antenna into an All Star node tethered to his mobile phone, using the phone data to connect to the internet.
