[Elecraft] K3 ERR KEY/PTT Problem

[Andy Faber]

Wayne, Eric and Gang,
I am planning to take my K3 to Aruba Tuesday night, but in testing it out on 
phone just now, I started getting ERR KEY messages, which change to ERR PTT 
if PTT is asserted.  The radio seems to receive ok but won't transmit.  The 
menus also don't appear.
  The manual says this is due to asserting key or ptt line in power up, but 
it happened when the radio was already on.
  Not sure of the firmware I'm using (can't communicate with the radio) but 
I think it's 3.83 and 2.54. The radio is Ser. 076.
  Any thoughts? Need to fix this quickly for WPX, or I'll have to go back to 
using our Pro2 (ugh!)
