Dear Andy, LF Group,Oddly enough, at the time your e-mail arrived, I noticed on the WSPR display that your signal frequency had jumped from 503869 to 503883 Hz. It stayed there for 2 frames (1838, 1840utc) and during that time it did not decode. After that, it reverted to normal frequency, and decoded normally. The other signals on the spectrogram behaved normally during this time, so I'm sure this was nothing to do with the receiver here.

However, he only manages a decode about one time in 10, randomly. Thefrequency is usually reported as ....855 instead of the ...870 it should be, although once in a while, it reports 870 and gives a proper decode. So itlooks as if he may have some sort of intermitetnt fault that affects sampling rate. |
