Got a great tip from Elecraft support on this one, which I'll relate here for the next person who is searching for K3/K3S "T>R Latency measurement timeout" on Google or the list when operating with Winlink.
The answer is to assign CONFIG:SYNC DT to a PF button (I used PF1) and then enable it when in DATA mode. This cuts the TX/RX latency *substantially* and entirely eliminates the 60ms of artifacts I was seeing during switching (the slow ramp and the 40ms drop-out). Presumably those artifacts were the result of switching filters. T>R latency on my laptop now varies anywhere from 60-130ms, and I'm sure some of that is just variance in processing in Winlink itself. The important thing is that the measure no longer times out, and the latency is in the ballpark where it needs to be for the mode to work well. The moral of the story is that if you're using a DATA mode that relies on quick switching from transmit to receive, assign Sync DT to a button and engage it when working with that mode. Kudos to Gary at Elecraft!

Belief in something doesn't make it real. And if you have to lie to support a position, that position is not worth supporting. ______________________________________________________________ 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
