[Elecraft] K3 Receiver Failure on Curacao

[jkhooper at rockisland.com]

Jeff, 

The K3 Manual describes a process to force a firmware download if "you accidentally load an old or incompatible firmware version and find the K3 unresponsive", and you might try that.   Page 45 of the manual which you could download from the Elecraft web site.  

1. Unplug from the power supply and wait 5 seconds 
2. Plug back in 
3. HOLD the K3s power switch in and after about 10 seconds you'll see the TX LED flash
4. Load the correct firmware version 

73,

All:
 
Here on Curacao, one of the members' K3 stopped receiving abruptly this morning, after he had called a couple of times and while he was just listening. He said it sounded like someone disconnected the antenna. 
 
Neither the Main nor Subreceiver are hearing signals. Using Antenna 1, Antenna 2, or RX antenna inputs makes no difference. 
 
The P3 display reflects changing the changing frequency (in digits, at top) with the VFOs, but the noise pattern displayed does not change. 
 
We've eliminated everything outside of the radio in the RF path as a cause. He went through the troubleshooting section of the manual. No Joy. 
 
This radio was carried down for the contest, and has only been here for 2 weeks in our air-conditioned shack. No danger of salt air contamination, which over time has "bad effects" on radios here!
 
Is there a "reset defaults" command to return the radio to a known pristine state, lest some parameter have been changed inadvertently? He reportedly needed such a command for his P3 before travelling to Curacao last week. 
 
Thanks for any guidence. He'd rather not pack it up for travel back to the States yet! 
 
(BTW, the PJ2T Multi-Multi operation this past weekend in CQWW CW was an all-K3 affair, with five stations. No failures, no problems, and the largest CQWW CW score ever for us! We appear to be second or third Worldwide Multi-Multi.)
