[Elecraft] k3 no control

[Don Wilhelm]

Joe,

Does the display show MCU LD and the red TX LED blinking?
If so, you need to follow the steps to "Force a Firmware Download" 
listed in the K3 Utility HELP file, or refer to the same instructions in 
the manual.

Get rid of that Prolific USB to Serial adapter and get one with the FTDI 
chipset - preferably the current KUSB.

Any how I did not realize that the USB to serial cable that came with the radio would no longer work because of outdated drivers. I had tried to down load drivers for the old prolific chip set serial adapter cable I don’t know if I got a bad driver or what happened because I did not realize anything was wrong until hours later. Anyhow I was never able to connect to the radio as far as I could tell. I never got a successful connection test it brought up the available current firmware versions but never displayed what was in the radio or I guess mean gave current to the radio. So when I found out from tech support that cable set would not work and I needed there new one. They said they would send it to me two weeks ago. I guess there no doing much of anything there in CA. but thought that was it for the time being.

Even the power button would not turn it off. I turned it off and back on. I did it multiple time leave differ time frames between the two. So I take it that the firmware is gone. And at this point I am just hoping I can get it loaded back up when ever I get the new cable. Thank you very much for any advice in advance.
