an introduction to G6CSY
 

Thank you Mr. Marconi...

My interest in Amateur Radio first started when I was at school. After building a low power two-valve medium-wave A.M. transmitter, I started to listen to the Short Wave bands at home. At first I only heard the very high power stations that came mainly from the Communist countries. Especially loud were Radio Moscow, Radio Havana and Radio Prague. Even though they were some of the strongest signals that could be heard, the "Russian woodpecker" , an over-the-horizon radar system, always powered its way over the top of everything, moving it's way up and down the bands as atmospheric conditions caused it's operating frequency to vary.

With help from reference books in the local library I improved the aerial system I had by using a longer wire and then taking the time to match it to the Radio Shack receiver being used by me at the time. I now started to hear Amateur Radio stations as well. The strongest signals I could hear on the HF bands were from the station of G3VLX in Petts Wood, operated by Deryck Buckley [sadly deceased April 2007]. I turned up on his doorstep on Saturday morning and was warmly welcomed in to his shack. It was through his enthusiasm that I ended up becoming a member of the Cray Valley Radio Society [CVRS] through the 1970's and 80's.

 

It was a CVRS club member who improved my listening station by donating a BC-348 receiver [a W.W. II radio from a B-17 bomber] as well as a homebrew power supply.

Taking the test

Through all this listening my interest grew, and in 1980 I ended up joining the national society, the Radio Society of Great Britain [RSGB], where I got my short wave listening [SWL] 'callsign' of RS44984. I then attended evening classes in 1981 and eventually got my Class 'B' Amateur Radio license, after passing both my of my City & Guild Amateur Radio examinations. I quickly got on the air with a crystal controlled Kenwood TR-2300 2m transceiver.

 

Two days after getting my license I was 'stopped by the Police'. I had set up a portable station in a field, and a passing dog-walker reported my 'suspicious activities' to the Police as 'a spy or something using a radio'! The Police Constable who arrived and investigated 'my spying activities' went away with a smile after wishing me good luck with the hobby for the future.

Although only on the VHF bands with my Class B license at the time, as I had not done the Morse code test and so was prohibited from operating on the short wave bands, I actively listened on the H.F. bands. I could have taken a 12 w.p.m. Morse test and changed to an G4 callsign (a Class 'A' license), but I never seemed to have the time. Everything changed in the middle of 2003 though, when the Radio Authority announced that the Morse code requirement for operating on H.F. was no longer required.

So, as from September 2003, I started to be active on the H.F. bands as well. Over the following months, I expanded my station's abilities by upgrading to a modern H.F. transceiver, an Icom IC-7400.

 

 

As well as the H.F. bands, this gets me access to the 6m/50MHz and 2m/144MHz bands. The antennas for these bands are on a tilt-over lattice mast that can raise up to some 15m when needed. Here, at about 2/3rds raised, the stub mast and rotator cage is supporting a 5-ele Tonna [for 6m] and a 9-ele Tonna [for 2m].



 

At the same time I had to replace the much corroded vertical antenna used for H.F. listening, with something more suitable for transmitting; a 10m-40m Hy-Gain AV-14AVQ with an MK80 attachment for 80m coverage.

 


To get on to the WARC bands of 12m, 17m and 24m, I have added a 'polymorph wire'. Depending on the weather conditions and the height of the mast, this wire antenna varies in it's layout. At the moment it is a '8m vertical > 10m horizontal > 1m horizontal >4m horizontal > 4m end-loaded sloper' antenna. But whatever 'kit' you have in your 'shack', it all depends on the band conditions:


These days

I am now QRV most weekends on the H.F. Bands, and on the 6m/2m bands if there is a contest taking place. During the 'magic season', I spend my mornings on the 6m band, looking for Sporadic-E contacts on CW and SSB At the moment I try to have a contact or two every weekday morning on 20m using JT65A mode. If the band conditions improve then I'll try 15m or even 10m as well. If no one is around I'll switch to one of the Phase Shift Keying [PSK] modes, such as BPSK31, BPSK63 or even QPSK.

 

My station activity, by band, since first licensed shows that 20m and 40m provide for the bulk of my activity. Hopefully as the Solar Cycle builds, my activity will increase on 15m and 10m.

 


For the first few years of my activity as G6CSY, I was confined to phone modes SSB and FM Since the availability of home computers and specialist mode software, my activity has now increased dramatically on RTTY and PSK.
 

 

As for propagation methods, the majority of contacts on HF are via the F2 layer in the atmosphere. The 6m contacts are mostly via Sporadic-E, with the 2m contacts via Tropospheric propagation.

 

Want a sked?

If you want to have a QSO on JT65A, BPSK, QPSK or something more exotic, please send me an e-mail to the address below, or take a listen around dial frequency 14.076MHz or 14.070MHz USB most weekday mornings between 0800-0900 GMT.
