[Elecraft] K2 Antenna Questions

[Guy Olinger K2AV]

The DB9 connection **IS NOT RS232** on K2. Three of the pins **ONLY** carry
the main RS232 but they need to be picked off with a special cable. This is
in the manual which you can download from the Elecraft site.

** DO NOT CONNECT YOUR PC AND K2 WITH A REGULAR SERIAL CABLE **

You can cause damage in both units.

Haven't seen this warning on the reflector in a while. The other six pins
connect to an externally housed 100 watt amp and/or 100 watt antenna tuner,
and carry proprietary signals and voltages that have nothing to do with
RS232.

I have a battery K2/10 with the 100 w amp and tuner in an EC2 enclosure.
Very slick. Uses the Y cable in the manual to control the stuff in the EC2
box and talk to the PC from the non-standard DB9 which is not RS232.

Good luck with your K2 and 73, Guy K2AV
