AA5CK via QRSS
Yesterday, I recorded a couple of hours of signals off of 30m, and ran them through my homegrown spectrogram code for fun. I found the following FSK CW signal (click on it to get it larger):
(The blank regions are the two minute intervals where I am sending a WSPR beacon message.)
With a bit of work, I identified the call, and exchanged email with Ted, AA5CK, who verified that it was his signal. He was operating from grid EM05eh with a power of 50mw into a vertical antenna. From my QTH in CM87ux, that works out to about 1250 miles. Very nice!
