Dennis, Yes, that's correct. Only messages hound receives especially Tx3 i.e. "OH3MA ZL9FOX -20" (that is just a normal message) initiates frequency moves.
If you mean by R-report e.g. R-15, then that station was *not* a fox at all. The only messages fox can send are Tx6 i.e. CQ, Tx3 i.e. a report -13 and TX5 either RR73 or combined RR73 plus a report to another station. You may study https://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf for further details. There is a derivate program that uses the combined "RR73; NE6I <ZL9FOX> -2" type messages and multiple carriers. That program can even be used on standard frequencies and on both timeslots although not recommended. Hound protocol has a lot of problems with it. Stations using it should be worked using normal FT8 mode. If that is the case and the R-report means what I said above, then on the reception of an R-report e.g. R-5 you should have sent RR73 or RRR, hi. 73, Reino OH3mA ----- Original message ----- Thanks, Reino, Are the moves by the hound all initiated at the hound end based on what it receives from the fox? In other words, the fox does not "tell" the hound to move below 1000 Hz, correct? All.txt is showing the fox responding with R-report for a couple of sequences but does not show me responding with a report for some reason, though I definitely did. This happened on two attempts to work him. Very strange. On the third attempt to work him, it does show the proper exchange, namely fox sending R-report, me sending R-report and then the fox sending RR73. --Dennis NE6I -----Original Message----- From: Reino Talarmo via wsjt-devel <wsjt-devel@lists.sourceforge.net> Sent: Wednesday, December 7, 2022 9:26 PM To: 'WSJT software development' <wsjt-devel@lists.sourceforge.net> Cc: Reino Talarmo <reino.tala...@kolumbus.fi> Subject: Re: [wsjt-devel] v2.6.0-rc5 F/H Issue >The third time this happened, the fox did respond to me with RR73 but I wonder >what happened there?

Hi Dennis, I don't know what actually happened, but the frequency movements are controlled at the hound station based on the received message sequence. Fox has no capability to move hounds as there is no frequency control in any of the message fox is sending. Hound should move to fox frequency for sending the R+rpt after receiving report from fox. If the hound needs to repeat R+rpt, then it would by its own move either 300 Hz up or down. So the first movement is initiated by reception of the report from fox. By the way the frequency movements as such are not mandatory for the F/H QSO as such. They only provide a higher probability for less QRM. Well there are still stations that call fox on the fox frequency and cause the QRM! In addition Fox will not answer to those stations by design! A careful study of the ALL.txt record may help to understand what happened. 73, Reino OH3mA _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
