[Elecraft] help - firmware hangup

[Robert G. Strickland]

Thanks to all for replying.

Several things... the radio doesn't respond to the PWR switch; it keeps 
blinking TX and MDU LD. The only way to cycle on/off is via the power 
supply.  I installed a Belkin usb-serial adapter which has worked fine 
in the past. I disconnected the microHAM interface and ran a K2 serial 
cable direct from the adapter to the radio [I have read here that the K2 
cable will work, and I have used it with the K3 previously, before 
getting the microHAM interface]. I restarted the computer, closed 
programs, etc. I get the same problem: no comm between computer and 
radio. It seems that the radio's ability to communicate with anything 
has been somehow corrupted. There's no way that I can force any software 
loading without a connection. Still stumped.
