[Elecraft] HI SIG Error on K3

[Don Wilhelm]

Do you have *anything* connected to the RX ANT or the unused TX antenna 
jack?

The K3 is "thinking" it sees a high RF level on the receive input.
Remove everything from the K3 except the power and see if you still have 
the problem.  The reconnect each cable one at a time and test again. 
Observe when it re-appears.

If you find that you still get the indication with nothing but the K3 
power cable connected, contact K3support.

Do you have a nearby broadcast station?  RF from that station could be 
getting into your K3.

With a HI SIG, the K3 will automatically turn off the preamp and turn on 
the ATT - that part is normal.
