Got my QMX on Monday March 10th. Did 2 QSO's 20m.
CQ'ing again on tuesday - no rx at all. Transmit is fine to me.
1 - board revision: Rev3 so Hans told me - got it assembled from QRP-Labs and do not open it.
2 - Bands: low, 80-20 m
3 - build supply voltage: 12 V
4 - FW version: 1_00_017
5 - modifications: none
I am slightly frustrated...
cheers - Raimund
