I was able to narrow down the problem. It is related to SYNC DATA (CONFIG:SYNC DT) which forces the same crystal filter to be used for both RX and TX. As long as SYNC DATA is OFF everything works as expected.
If SYNC DATA is ON: (1) Toggling between SHIFT/WIDTH and LO/HI CUT is inhibited (2) SHIFT control is inactive (3) LO CUT and HI CUT both act as WIDTH control Am not sure if these limitations are a logical consequence of SYNC DATA ON or an unwanted side-effect. 73, Markus HB9BRJ -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-SHIFT-WIDTH-in-DATA-A-mode-tp7601016p7601025.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
