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.

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. > >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: Thu, July 8, 2010 11:37:12 PM >Subject: Re: [digitalradio] JT65-HF on 14076 > > > >This is probably a case of the transmitting station over driving >(too much audio drive into transmitter ) > >Or perhaps the transmitting station is over loading your receiver. > >I have no idea whether you should get 2 decodes or not in this situation or >mot >. > >In just straight WSJT65A I have often seen decoded signals with very >different S/N ratio's indicated, such as + 6 and - 25 dB. > >73 Rein W6SZ > >-----Original Message----- >>From: Russell Blair <russell_blai...@yahoo.com> >>Sent: Jul 9, 2010 1:23 AM >>To: Digital Radio <digitalradio@yahoogroups.com> >>Subject: [digitalradio] JT65-HF on 14076 >> >>I am seeing 2 Images of N4CE one at -554 and Distorded and the other at +175 >>witch lookes fine but I'm only getting one decode.
