Hello,

for the FDM-DUO use menu 85.

For FDM-S1 and FDM-S2, use the SW2 software, right click on the spectrum/waterfall and choose "Frequency Calibration", then "Reset Offset".



Regards,

Vianney

I am very frustrated as my Elad FDM-SW2 are way way out of calibration by some reason. We are not talking Hz, but moremany kHz on mediumwave and shortwave.

What can I do to reset the whole set to factory default settings - including calibration frequency?

I am not too familiar with SDR-radio and after nightmares ready to give up everything, so this is my last option.

Yes, I have already looked at other topics in this group, but without getting the right answer.

Best regards
