[Elecraft] K3 MCU LD

[Josep Torres]

Hi guys,

New to this list. Been suggested by a fellow ham.

I have a K3 that get stuck while trying a firmware/software update.
Problem is that seems to be no communication between the PC (WIN7) and the K3 as I get a message of “K3 is not responding”.

I use a Serial to USB cable and have been told that not all cables work. This morning I will try to buy another one and try again. If this doesn’t recover’s the K3 from MCU stuck, I will have to sent it to Italy to Official Service to get recovered from them. Of course this is the most expensive solution, but the only way I see to get it back to life.
So, what do you recommend for such a cable so PC and K3 can communicate.?

Thanks,


73,

Josep
