Hi Jim, First, in my experience 8msec delay is THE ONLY point if we speak about TX delay. Any setting above 8 msec makes CW choppy. This subject was discussed here some time ago. It has been checked here on 4 different K3s and they are all the same.
Second, I do not insist on anything. I have just expressed my wish to have configurable TX delay in highly configurable K3. Having said that, I am afraid your statistics is not applicable to the majority of SO2R stations that I know and practically all the MS stations that I know. Even most of the SO1R stations here prefer using PTT in the contests. Actually I am really curious what percentage of contest stations use break in regularly in the contests. That might be a good question for a poll in "cq contest" reflector. 73, Igor UA9CDC >> I had to build small circuit that makes use of inhibit signal in my >> K3 to extend rigid 8 ms built into K3 although it would be more >> logical to have programmable TX delay built into the transceiver. > > Hi Igor, > > First, I suspect we may have a language problem.
