QCX WSPR transmit - not clean output

Victor Nagoryanskii
 

Hello,

I've noticed that sometimes I receive two or even three WSPR spots from the same station in the same time slot (see wspr_reports.png).

In order to troubleshoot this I started to receive my own WSPR transmission using IC7300 and the latest WSJT-X software and indeed spectrum looks not so nice. Please see attached screenshots from the radio and WSJT-X software.

QCX power output is about 2 watts, and the pattern is? the same for 40 and 20 meter versions of the kit.

My question is this a known behavior? Does somebody else noticed this?

Cheers,
Victor, PA8MM
