R2BM now calling in FST4.

Tonight, both DL0AO and DF6NM received two FW15-traces, starting 20:00 and 20:30,  obviously from RA6A. Strangely, the decoder displayed the correct locator, power etc, but istead of the callsign only "00" (zero zero):

250612 2000 0 -38 0.4 0.137542 00 KN96 20 0 15
250612 2030 0 -27 -0.1 0.137542 00 KN96 20 0 15

WSPRnet did not report these two spots.

Hi Alex RN3AUS,

I looked on your nice new "birdhouse" grabber, and listened to one of the hourly wav recordings. Interestingly, DCF39 is on 1850 Hz, and HGA on 1550 Hz with inverted FSK. It looks like you are using an IQ-receiver, centered on 136.98 kHz? Also the frequency scale of the Eu-slot around 136.173 kHz is upside down. If you want, you can invert it by ticking the "LSB mirror" option in Spectrum display settings - part 2.

I hope that I will be able to leave a trace one day.

Clear signals on DL0AO.
