[Elecraft] KIO3 Digital Board Failed and WSJTx transmit issues

[Jeff Wilson]

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
