I don't need a fix for this because mine is working now, but I thought I'd pass along what I did to correct my problem in case anyone else was having similar issues. Please don't send me an email to tell me I was an idiot and I should have known this, or to read this/that post. I just wanted to pass this along to possibly help someone else out. I have a K3 that connects to a MicroHam band-decoder and a Palstar AT-Auto tuner with a split RS-232 cable. The band-decoder also drives my remote antenna switches for "one-click-and-everything-is-set" for operation. I have a computer background and this set-up was completed about 2 years ago and has performed well at 4800 baud. When I put the P3 in the mix, the RS-232 communications between the devices started mis-behaving. The band-decoder would not know what band it was one and the AT-Auto tuner would start trying to tune for the wrong band. The K3 would change from 4800 to 38400 baud. I know the P3 and the K3 communicate at 38400, but I thought (and maybe I was wrong) that the K3, the accessories and the (output) RS-232 settings on the P3, should all be set at 4800 and everything should work. If I turned off the P3(but left it in line) everything would pass through and work properly at 4800. the K3 and P3 are at current/latest Firmware revisions.
Anyway, Saturday, I set everything (K3, P3, Band-decoder, PC serial port and AT-Auto Tuner) to 38400 and everything is playing nicely and switching properly. Hopefully this may help someone with extra RS-232 gadgets like me. 73, Tad, WF4W "What a long, strange trip it's been" The Grateful Dead Truckin' ______________________________________________________________ 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
