Re: [Elecraft] K3: KIO3 dgital board failed (I think)
I had exactly that same problem, Ed, and I also first thought it was the USB/RS232 cable (which it wasn't). I also do not need the direct USB connectivity, or the associated internal sound card. Luckily, I was able to buy replacement boards from someone who had done the upgrade to the KIO3B for another ham and still had the old boards, one of which ... the audio board ... was itself bad but at least the RS232 board was good. Problem fixed. In my case, the KIO3A apparently was damaged by a line transient that came in via the laptop that was connected to the USB/RS232 line. Most everything was disconnected at the time, but that line wasn't. I had sent an email to Elecraft technical support when I first had the problem, asking whether or not they had replacement boards or whether they could fix the KIO3A. The tech didn't bother to answer either of those questions and simply replied with a rather curt "just upgrade to the KIO3B ... you'll be happier". Somebody could probably make a small business gathering various older K3/K3s boards from folks who had done various upgrades in order to service users like us who can't get help anymore from Elecraft. 73, Dave AB7E On 9/14/2020 1:43 PM, Edward R Cole wrote: My K3 SN 4340 bought in 2010 apparently has a failure in the RS232 I/F.

Oh yes. And the only way out is to upgrade the whole system. Or look for used items here.

[Elecraft] K3: KIO3 dgital board failed (I think)
My K3 SN 4340 bought in 2010 apparently has a failure in the RS232 I/F.
