It's great that EU LF activity is picking up again. Last weekend I noted the following stations - DK4U DK7SU DL2HRE F6BWO G3KEV M0FMT OK2BVG PA3CPM PA3FNY PA4VHF and S57A (all good strengths) Today I
I'll be putting out a few CQ calls, straight CW, on Sunday from about 0900 GMT 136. 50 kHz. If there are no takers I'll send some ' test ' transmissions - QRSS1 - on 136. 92 kHz. 73 Chris G3XIZ The
