KIO2, KPA100 - is SWR value available via RS232?

[ub5_073_oleg]

Thinking about remoting my K2 (currently QRP with KAT2, one
day with KPA100) via TCP/IP (e.g. with Ham Radio Deluxe), I
would like to know if SWR value is available via
- KIO2 serial interface?
- KPA100 built-in serial interface?

or do I need some external device like W1?

I am going to use an external non-automatic tuner, that's
why I need a monitoring of SWR - via PC because of remoting.

I'm not sure this will help for your situation, but you could determine the SWR with CAT commands. The K2 will display SWR when in TUNE. So sending SW20;  to enter TUNE and then sending a DS; command to read the VFO A display will give you the current displayed SWR.

David, thanks for your reply!

I gave it a try in a terminal program.

After connection at 4800 baud,
DS;  returns the frequency
SW20;  enters tune mode (I changed the tune mode to CALS to
have enoogh time for the following command)
DS;  returns a "?", although I see the SWR on K2's LCD

Am I doing something wrong? My firmware is 2.04P  1.09

Hmmm. DS; may not work during transmit on the K2. My K2 is not hooked up, so I cannot test. Could someone please confirm whether DS; works during transmit on the K2. If not, this method will not work. :(
