Hi there ...
Yesterday night (03:00 UTC more or less) some new signals on 21.1. There´s
two files, one of them is the 3rd audio sample of the morse transmition (may
26th) at http://py.qsl.br/fskmorse3.mp3 .
The second one (http://py.qsl.br/21_1K0001.jpg) is the Spectran snapshot of
another ongoing test at this frequency. There is 5 carriers, the 3rd one at
21.1KHz (700Hz). Too much man made noise yesterday but it´s clear the signal
at 700Hz (21.1KHz), signal above is 21.4KHz and below is 20.9KHz.
Some moments after this "burst", started an 83Hz shift FSK (???) emission
Active from "DC" to 24GHz
