[Elecraft] K3 13.8 VDC power

[WILLIS COOKE via Elecraft]

I have noted that if you remove power it does not give the processor time to save the last frequency and other settings that it automatically saves (operating conditions).  I had this happen with a defective power supply and a few times when the power was automatically removed.  My dog likes to sleep under the operating desk.  Lately he has been picking on my cable modem and router. Willis 'Cookie' Cooke, TDXS DX Chairman K5EWJ & Trustee N5BPS, USS Cavalla, USS Stewart

It IS possible to send the K3 off to never-never land by removing the 12 volt 
input before
shutting the radio off with the power switch. I've had it happen whilst mucking 
around
behind my desk and accidentally pulling out the Anderson power-pole connector.

If you've saved the settings using the K3 utility, you can reset everything 
using the
procedure on page 63 of the K3 manual. NOTE: This did not work with my rotor
control plugged into the ACC socket! If you didn't save the parameters, you will
have to manually reset everything! SAVE!
