[450] Very Strong 70cm Beacon

[George Andrews]

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
