Hi Joe, VLF,

Same problem at RC4HAA. They put their grabber online at
http://136.su/grabber/ and granted remote acces to their PC. The PPS
looks like in the attachment. Looks like a C is shorting the pulse.
However there should be no C in the circuit.
Has someone an idea? Does it happen on some soundcard types? Maybe a
large C like 1000uF would help?

73, Stefan
