Hi EdI just solved a similar problem with my K3 (s/n 1900 plus all K3 upgrades) setting up WSJTx after Windows 10 update and having to renumber COM ports that use FTDI chip USB adapters. I could not set my usual config for CAT and PTT (using CAT) and got a PTT ERR on the K3 which would go into TX but without power on WSJTx boot up. Just pushing TEST on and then off reset the K3IO and I was off to the races. This is in the original K3 manual, page 19 I think.
Found on a previous post after search PTT ERR. In the K3 Manual: " If a PC or other device asserts RTS or DTR DIGOUT 1 while you're in the PTT-KEY menu entry, the K3 will enter TEST mode as a precaution. Page 19 In the tables below, 0 = 0 VDC, and 1 = device Normally, when the K3 is turned on, a 5-VDC logic supply voltage. signal appears on ACC pin 7 (K3 ON)." I thought my K3IO was toast as WSJTx software and FTDI serial USB adapters all worked fine with my FT-1000mp. This was caused by adjusting the K3 MENU and CONFIG setting while changing things on WSTJx at the same time.....must have been in panic mode. Hi. Hope this helps.73Jeff VE3CV ______________________________________________________________ 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
