Ham Member Lookups: 2679


I was first licensed as G8HRJ in 1973. I took the Morse test in 1975 to get the G4 ticket. I didn't operate much for several years because I wasn't settled in one place long enough. In 1989 I bought my present house complete with garden and tall trees. Within a year I had some reasonable antennas up and made full use of them, on HF and VHF. For a while I ran a 24/365 AX.25 packet node with ports on 70, 144 and 432 MHz using the callsign GB7YA.

In 1994 I was introduced by a fellow ham to a thing called 'the Internet'. He was into TCP/IP networking and was using this amazing thing called Linux and a dial-up internet connection. I was instantly hooked and for the next 20 years that became my new technical hobby. I didn't transmit a single cycle of RF after 1995 for nearly two decades.

Fast forward 20 years, and the Internet has in my opinion become a bit boring. It's a utility and it just works.

I started to take an interest in the radio again in 2014, discovering some fascinating things that had arrived while I wasn't looking. 5 MHz, SDR, WebSDR, NEC modelling and LoTW to name a few. I tentatively dusted off my old TS-450S, replaced a dud electrolytic, threw a bell-wire doublet up and started to listen and gradually it all started to come back.

I now run an Elecraft K-line: K3S transceiver, P3 panadaptor with SVGA option and external HD monitor, KPA500 amplifier and KAT500 ATU.

The microphone is an Electro-Voice RE27N/D - far too good for amateur radio! I originally bought it for music recording.

My HF antenna is a simple doublet, 26.5 metres long and 12m above ground, oriented north-south. There's about 10m of 300-ohm slotted ribbon line hanging vertically down, a 1:1 ferrite choke balun and 50-ohm feeder in an underground duct to the shack and the KAT500.

Next projects are to get a small Yagi up for 50 MHz, and to build a remote relay box to switch the doublet to a 'T' driven against earth for 1.8 MHz.

I use a mixture of SSB and data modes: mainly JT65, JT9 and MSK144 at the moment. I've no interest in CW. This is 2017, not 1917, and I'm an engineer not a museum curator!
