Heelo Lowfers,

Dave, G3YXM and I just completed the first PSK31 between the England and
Germany on 137.450 kHz. Despite the fact that Dave's signal was nearly
burried in the noise, the G3PLX software decoded his signal so that I could
give him 439 as a report. I received 339 by him. In his first over I had
some difficulties to tune onto his signal because my MV62 synthesizer has a
step resolution of 10 Hz with a kind of RIT-control allowing 0-10 Hz to be
adjusted. A PSK31 signal must be tuned to an accuracy of a few Hertz only,
so this is really a challange. The PSK31 software has a build-in AFC, but
with the low signal levels on LF it has difficulties to tune in onto the

Dave, thank you for this nice QSO!

Best 73
