Re: [digitalradio] JT65-HF on 14076
Hi Russell, OK. I do not know whether you are active with WSPR,, but there I have also seen at times multiple decodes. One station call, same time ,different indicated frequencies and S/N's I have not seen it recently and in those cases is was not due to overloading on my side ( receiver ) but something ( distortion ) that was produced on the transmitter side ( it happened every time the station made a transmission ) Never really looked further because of certain sensitivity issues that could arise asking questions. I think one should always try to prevent overdriving the transmitter and if detection is done using FFT's, distortion becomes even a bigger no no. 73 Rein W6SZ -Original Message- From: Russell Blair russell_blai...@yahoo.com Sent: Jul 9, 2010 8:20 AM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] JT65-HF on 14076 Tnx Rein, I'm going to keep an eye this and see if it happens agian, that was the first time I saw it.

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.

Re: [digitalradio] JT65-HF on 14076
HI Russell, There is gain and gain. 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.
