[Elecraft] K3 radio no receive no transmit

[Don Wilhelm]

John,

Don't forget to check the connections on the outside of the K3 as well.  
A loose PL-259 connector could cause that same behavior.
PL-259s need to be tightened finger tight, and then given just a little 
bit more tightening with pliers to assure a good connection to the coax 
braid.
