Rein, I'm using the SignaLink USB and the audio is showing to be only about half scale on the program, I have been checking today and it has not happen only that one time on 20m. So I will keep an eye on it.

If you use gain in terms of obtaining a better noise figure on receiving, I do not believe you have to worry about that kind of gain, It might be that you have perhaps too much gain in your audio section ( going into sound card and via sound card into DSP decoding operations.) So It would be interesting if you had a signal that would always show the double decoding and then to be able to make changes in your receiving chain and see whether those changes had any effects. 73 Rein W6SZ -----Original Message----- >From: Russell Blair <russell_blai...@yahoo.com> >Sent: Jul 9, 2010 9:58 AM >To: digitalradio@yahoogroups.com >Subject: Re: [digitalradio] JT65-HF on 14076 > >Yes Rein I understand, this was one station but with two signals that started >and end at the same time and one decode, I'm running jt65-hf with multi-decode >checked and had the gain all the way up, because I need it on 17m, I have cut >the gain back and keeping a check to see if it happens again. > > >73 Russ NC5O > 1- Whoever said nothing is impossible never tried slamming a revolving door! >2- A government big enough to give you everything you want, is strong enough >to >take everything you have. > >- Gerald Ford > > >" IN GOD WE TRUST " > > >Russell Blair (NC5O) >Skype-Russell.Blair >Hell Field #300 >DRCC #55 >30m Dig-group #693 > > > > >________________________________ >From: "rein...@ix.netcom.com" <rein...@ix.netcom.com> >To: digitalradio@yahoogroups.com >Sent: Fri, July 9, 2010 8:48:38 AM >Subject: Re: [digitalradio] JT65-HF on 14076 > > > >Hi Russell, > >OK.
