[Elecraft] K3 Serial Cable to PC

[Paul Kirley]

Your original problem (VOX=OFF and beep) could have been caused by
key-down at power-up.  

Check and/or disconnect your keying lines.  The K3 may then start OK.

If you key via the RS-232 port, you may have a computer or cable problem.
But you can't be sure until the K3 is unkeyed.

73, Paul W8TM

>   After a 10 days trip i turned on my K3 and it was "blocked". 
No buttons working, no rx, nothing. Only the displays were working,
 on the lcd the msg: VOX=OFF and a continuous beep.
