Re: LOTW showing “cross” band contacts


When logging FT4/FT8 contacts that originated from UDP messages, a single frequency is part of the message. It is the radio VFO frequency plus the transmit audio. This is logged as the ADIF FREQ field. How does Logger32 calculate the ADIF FREQ_RX field? The UDP Status messages tell the audio offset of each station it decodes. So, the station being logged was transmitting on the frequency (as shown in the Logbook Entry Window) plus the audio offset as shown in the UDP BandMap. This is logged as the ADIF FREQ field. Or something like that ... SeventyThree(s).

I also had the issue. But it was operator error.


WSJT you never changed the frequency in the program.  Mine was a 60m contact and I had 6m on wsjt. That’s why it di the cross band.

Hi Dale.


Please check section 38.10 of the User Manual for me.  Does that help?  I don’t use SO2R so haven’t had the chance to test the details.  Corrections & comments welcome.

On a recent manual upload (from Logger 32 to LOTW) many Qs in LOTW showed the band as “cross”…which they were not. Everything in Logger looks fine and all the Qs were made with WSJT X.  Upon looking at these Qs in LOTW, they showed the “receive” freq as the  freq. of my second rig ( always set to 2 meters).  I’m not sure what caused this nor how to fix it. Help appreciated.
