Having been off work today with a stupid cold, I’d been doing a little reading around. I was enthused reading Roger G3XBM’s ever-interesting blog about the experiments that he is making at optical frequencies with 481THz experiments using LEDs. I remembered I’d had a QSO with Gordon G8PNN last year when he mentioned these experiments. Fascinating stuff!

What intrigued me is that these experiments have been going on for a while and that Australian amateurs have quite a history of experimentation in the field. I found and enjoyed ‘Optical Communication for the Amateur’ written by Chris Long in 1979 and later revised. Back in the UK, Eddie G0EHV has an interesting page on the optical experiments in the North East of England.

I wondered whether Dave WW2R/G4FRE had done any optical experiments. It turns out that he hasn’t, but his website contains details of some fascinating ‘First’ UK QSOs on 134GHz and 142GHz which I think you will also find fascinating.

Oh and the picture? I took it off Dave’s website (Dave, I hope you don’t mind!). It shows a very youthful G4VXE in the middle (doing nothing, apparently), Kelvin GW4TTU to the left and Dave G4FRE on the right. We were on Mynydd Maen in South Wales preparing for a microwave contest. I’m guessing 1986 or 1987.

It’s not often I hit some DX but WSPR helps me out quite a lot. Here’s a screenshot from my latest 1w big gun escapade

1w into Hustler 6-BTV

Whilst some might say that lifes too short for QRP. Newly licenced hams take note. 1w into a lossy vertical in a bad location doesn’t mean you’re stuck with QSO’s as far as the end of the street.

All this was achieved with a modest transceiver (IC-7000) and a modest antenna (Hustler 6-BTV with a few radials). The lesson here is that DX isn’t just for those with limitless pockets of cash, elevated QTH’s and antenna systems that can rival your nearest broadcaster. You just might not be talking to the other station!

In a world first, or maybe just podcast first, the guys throw caution to the wind and actually product an episode with some real Linux and ham radio content. We know it’s shocking, but sometimes–just sometimes–a miracle happens and you get the belly laughs along with something to stimulate your gray matter. We can’t promise this will happen in the future, but this time you’re safe.

On the Linux side, Richard found an article on the ARRL Web site which leads to a discussion of OpenOffice (Libre Office) and Scribus, two excellent document preparation suites. On the ham radio side, Russ discusses some useful Android applications which might be helpful to those operators who want to use their devices for logging, CW training, PSK31 digital mode communications and more.

Thank you for all the donations to the Hamvention fund. Russ hopes to see as many folks as possible during his time at the show. LHS will be in the North Hall, booth 131.

While at NAB, George of  AmateurLogic.TV  interviewed me. We had a great time talking about many ham radio topics. It is always fun to meet up with George.

Today is my 59th birthday. I opened my inbox to find several greetings messages from various websites and forums. Ah, you’re never without a friend in cyberspace!

Olga and I are not planning any special celebration today, though Olga is such a great cook that I prefer eating in anyway. I’m still off wine, despite still having a cupboard full of the stuff from when I was a member of a mail order wine club. At the moment I have enough trouble staying upright when sober. Surprisingly, I really don’t miss it (wine, I mean, not staying upright.)

But today deserves celebration as the birthday doctors told me I’d have a slim chance of seeing. Pah! Doctors! What do they know anyway?

There’s no reason why you, my loyal readers, can’t have a drink on my behalf, though. So here’s hoping I’ll still be hamming, blogging and beating the bugger in 365 days time, and many more days after that.

Thanks for all your support, and for reading my blog.

And the winner of 500 free full-color QSL cards is…
