[450] Very Strong 70cm Beacon

Thu Dec 20 16:42:02 EST 2012

I am bidding on one. I will definitely have one soon. Plan is to get it
working on VHF and up and see how it plays, then add the MF/HF converter.

Yup I ordered one of those earlier too. Huzzah to 2mhz band scopes.

Do an ebay search for e4000 and take your pick.

This is good stuff. The brain, as well as the body requires exercise and
stimulation of the intellectual type. As the body turns to mush without
exercise, so too does the brain. Anyway we need more technical discussions
and talk of glow in the dark radios (reference to recent DX60 etc.
discussions).

So when does the HF AM net start??? I don't have an HR10, so I use either
the FT950 or Icom 726 for the receive. DX60/HR10B for transmit.

I am also thinking about an SDR using one of those USB dongles. Anyone else
explored this to the point of a working model?

Alright, Alright.....suddenly there is WAY too much technical stuff going on
here for us appliance operators!

Good show, Herr Foege!

Merry Holidays to all....guess we won't be getting together before Xmas, but
maybe before the New Year?

Peace and Love to all......and Woody, are you still alive?!

Ok. I did actually manage to figure out a way to get one of those software
decoders to decode a WAV file. I guess I just didn't look hard enough
before.

The text follows:

k1iig/b fn31ln

It's loud as hell on 432.200 MHz and only on a teeny tiny little whip going
into my SDR.

Apparently the guy has got it going into a wheel (?) antenna up @ 450 ft.
Now I'm not sure if this is AGL or above sea level...

He has got the oscillator for the CW beacon phase locked to some kind of
standard. And what's really funny is, I can hear the same beacon on 61 Mhz
or so at much reduced SNR. Now, I wonder if this is just some kind of mixing
artifact from the SDR or I'm actually hearing his reference signal that he
might be transverting to different frequencies. He did say he wants to get
up a Ghz beacon soon.

Now I'm interested...doing a little radio detective work so to say. I'm sure
you all hear him loud and clear on 432.200 Mhz, but is anyone hearing
anything around 60-62 Mhz that is the exact same beacon CW string??

I'm going to contact him and ask him for some details of his beacon setup.
If it turns out he has a 60 Mhz phase locked signal somewhere that he is
converting up or down to do his beacon...then I'm going to be laughing my
ass off that I can hear it so far away, and I think he'd have to know about
it.

Anyway...thought I'd ask for some help from the crew in determining what's
going on there...

Cheers,

John

I don't know. I'm working on learning CW though...and I can't find a decent
decoder that decodes WAV files...it's all live decoding software...bummer

what does the cw say?

There is a very, very, very strong signal on 70cm @ 432.20 CW

Sounds like a beacon...anyone know anything about it?
