[Elecraft] K3 Dead MCU Load

[N8XPQ]

Tom,

I am curious how you are communicating with your K3. Are you using a
USB/serial converter? Make sure you don't have anything else in the chain of
communication, then try it again. I had a similar problem in the past. Also,
if you are use a USB converter, make sure the drivers are up to date. Feel
free to contact me off the list for further q's. my call @charter.net

Best of luck,

Mike N8XPQ
