[NLRS] Beacon Doppler

[Mike King - KM0T]

Hi guys, was messing around in the shack with my 10 and 24 GHz beacons 
pointed out the basement window.  I have been using these for frequency 
coordination since they are run off a locked source.

Anyway, I looked up at the 24 GHz beacon signal on the SDR-1000 and saw two 
peaks....huh?  Tuned on the nice narrow one...the beacon - solid cw 
tone....and then the wide one up a 1 KHz or so...it was wide and raspey.

It was a reflection of my beacon signal, dopper shifted back to the 
Gridinator (24 GHz tower setup)....very cool.  I turned the antennas a bit 
in az and elevation to peak it up.  I then recorded some of the signal with 
the SDR-1000.

Then I checked 10 GHz, it was the same, but about half the distance away 
from the narrow local beacon cw signal, which is about right.

Looked outside and it was snowing like crazy...wet big flakes and coming 
down good, windy too.  The antennas and beacons were pretty much pointed in 
the direction that the big wet snow was coming from.

Perhaps I can play the file at Aurora 06 for you all.

The beacon on 24 GHz is very low power 5 to 7 dbm, the 10 GHz about 10 to 12 
dbm.

Just a neat observation....

73 and good luck in the storm...
