For me it is DHO38 and HWU. I think that 70 dB should be fine. No problem for a standard soundcard. > Will strong > sferics be a problem [...]? From my observations i can say that the sferics amplitude has ever been lower than the strongest MSK transmitter. It may be 30 dB above the noise of a quiet day but not 100 dB or so. 73, Stefan
