The KRSN DX test is on!
American Broadcast DXers (http://abdx.org/) announces a DX test for
KRSN 1490 kHz, Los Alamos NM.
The DX test is scheduled for early Saturday and Sunday mornings, Jan
21 and 22 at midnight Mountain time.

Just a reminder about the KRSN DX test coming up this weekend:
KRSN Los Alamos, NM 1490 kHz
The DX test is scheduled for early Saturday and Sunday mornings, Jan
21 and 22 at midnight Mountain time. (0700 UTC)
The test will run for 10 minutes each time.
Included are sweep tones, 20 WPM Morse
Do far we've had verifiable reports from CA, AZ, CO, NE and OK. A
couple of listeners used the remote tuner in Grand Junction CO.
QSL cards will be sent soon.
Here's a spectrogram of the sweep tone used on the KRSN test, as heard
in northern Colorado
It's 47 CFR 73.72
