[Elecraft] OT-P3 capture of a 17M intruder

[Tom H Childers]

I sent CODAR a message and a screen capture from the P3 yesterday.

The president of the company said the signature of the RF signal was
not from their radar.  He was very helpful, saying that if I could
send him a recording of it he might be able to help find out what it
is.

If he returns this morning 1450Z or so I'll record the audio. I  do not believe it is CODAR.  More ears would be useful :)
