[Orion] USING ORION'S RECEIVER

[BarryG]

 Thanks for preparing the document and sharing this info Sinisa.  The 15dB fall-off for AGC Threshold setting is more than I was using and I look forward to experimenting with your guidelines.  I think the info should certainly help new Orion users get their receivers sounding much better.  I found soundcard spectral analysis much better than using the S meter for judging the 15dB decrease you recommend.  The suggestion to use the soundcard to center the narrow cw filters is also an excellent one. FWIW, the sensitivity adjustment you suggest for my Orion works out to simply rx preamp off for me, which is how I had been using it. It was refreshing to see you also feel that narrow cw filters are not necessarily the solution to pulling out weak cw signals on uncrowded bands, despite what K6SE and others insist. 73,Barry N1EU--- On Fri 02/27, Sinisa Hristov < shristov at ptt.yu > wrote:From: Sinisa Hristov [mailto: shristov at ptt.yu]To: Cc: orion at contesting.comDate: Fri, 27 Feb
