Virtual Amateur Radio

I have to confess, I have not tried "virtual" ham radio for many years. It is a poor substitute for the real thing. Even with my poor voice these days, the real thing offers so much more. Nonetheless, it will appeal to some, especially when HF conditions are poor.  I expect this will become more popular in the next few years. As it name implies, virtual ham radio uses the internet rather than the ionosphere as the medium of "propagation". If all you want is to chat, this may be for you.

Low storm risk in the UK

With the nearest storms being in Austria, I think I can safely "play radios" today.
 Just I case, I'll keep and eye on the maps.

Where I was born - NOT amateur radio

The picture shows where I was born in Devon, UK when a nursing home after WW2. The film "Sense and Sensibility" was, in part, filmed on the Flete estate. This is Flete House. These days they are posh retirement flats.

Not much Es on 6m JT65 yet

I have been on 6m JT65 for some time. No Es seen yet today on 6m, although I am supposed to have spotted a station in Indonesia on 6m, which I do not believe. This suggests the pirate is in the UK. Sad.

UPDATE 1045z: Some Es with my 1W ERP 6m JT65 being spotted in Finland.

Sunspots and 10m - Friday June 23rd 2017

Solar flux is 74 today and the sunspot number 23. A=6 and K=1. 10m? Expect Es but F layer N-S is more doubtful on 10m.

ICOM IC703

Until I sold mine to a local fellow ham several years ago, I used this rig most days. They are hard to find now, and I am not surprised. In many ways I regret selling mine, but it went to good home and is well used.

Sadly, there is no real equivalent QRP rig outside of Japan. The IC7300 is probably the nearest, modern rig, but the 10W version is only available in Japan. If the 10W version was available in the UK, I would buy one, as I suspect would many.

The IC703 is a 10W 160m-6m multi-mode transceiver with an auto-ATU. It has a good DSP filter. Altogether a good, solid radio.

VLF transmitters

Recently I had an email asking me if stereo amps (100W) would make a suitable VLF TX. The short answer is "yes", although these are designed for a low impedance load, so would require a suitable matching transformer. I have not tried one.

Storm gone, so back on 6m JT65

The storm has passed through, so I have returned to 6m JT65 transceive (1W ERP). I tried replying to a few CQ calls, without success, so I am currently in beacon mode sending "B G3XBM JO02". Best report is from CT2IWW (1382km). There seems less Es about at the moment.

UPDATE 2038z: As well as spots of OX3LX (2570km) which I do believe, I also (supposedly) spotted another Indonesian station, which I do not believe: I am convinced this is a pirate somewhere in Europe. Unless proved otherwise, I am dismissing these latter spots.
