Edgar seems to have no problem switching between qrss60/120. I tried Stefan's settings but still no sigs on the screen. The monitor scope is showing a nice little green line with some random noise for QRSS60 and 120. It seems the signal is getting in but being lost by the computer/sound card for QRSS120. Perhaps try another computer? 73 & TNX Joe VO1NA On Mon, 25 May 2015, wolf_dl4yhf wrote: > Hello Joe, > > I will check the QRSS120 configuration soon, maybe I had copied the settings > from a computer where the input level (soundcard) was rather high, and the > signal in your case is much weaker. > When turning on the "input monitor" (scope-like gadget), does it show a flat > green line, or a noisy-looking waveform ? > > Flat line -> not good (wasting dynamic range of the soundcard's A/D > converter) > Green waveform -> ok > Red waveform -> not good (not much headroom before clipping) > > Details: http://www.qsl.net/dl4yhf/speclab/circuits.htm#monitor > > Cheers, > Wolf DL4YHF . > > > Am 24.05.2015 15:01, schrieb jcraig@mun.ca: >> >> Dear Group, >> >> A QRSS60 detection at 5.2 km is the best DX for yours truly to date. >> Although there was a detection at 7 km, this was probably via conduction >> from a nearby mains line.
