I have a K3+RRC setup at my remote site which I use both locally and remotely.
Don't use "VGA" cables of any kind for any purpose other than connecting a VGA monitor directly to a computer! Use only full 15-pin cables, connectors and adapters except for the documented "interrupter" that some folks need when using external sequencers. I have a daisy chain of verified 15 pin Y adapters hanging on (for dear life) to the K3 ACC connector. It's a very delicate mechanical monstrosity but so long as I don't wiggle anything back there it does hold together and it works. They feed the KPA500/KAT500, a pair of band decoders, and some other stuff. The band decoders drive a pair of bandpass filters and a jury-rigged diode matrix for antenna switching via a Six Pak. (The pairs of things are because it's an SO2R station when I operate locally and I get my choice of two amps when operating remotely.) I switch the K3 9-pin RS232 connector with a two position rotary switch designed for serial ports. These switches are readily available from surplus stores and on-line. In the "Local" position, the K3 connects to the P3 which connects to the logging computer. In the "Remote" position, the K3 connects to the RRC. I also have a SteppIR controller eavesdropping on the serial communication on the radio side of the switch (center, switched port). I put it into General (frequency tracking) mode when I leave the house. I switch it to Ham mode and change bands manually when I'm in the shack. This arrangement works fine for the serial port except for extraneous clicks in the SteppIR controller when in General mode which I'm yet to understand fully. I think there is a significant amount of extraneous frequency and mode reporting on the K3 serial port. I can't hear it when I'm 200 miles away, so it doesn't bother me except for the possibility of wear and tear on the relays. I parallel the PTT and Key lines from the local external keyer and the RRC. I parallel the local mic with the mic output of the RRC. I use the PHONES jack on the KIO3 for local audio out and the SPEAKER jack for the RRC audio in. I have to remember to keep SPKR+PHONES set to ON for this. I run AFSK into Line In for local RTTY and so far haven't used RTTY remotely, but others do that, too. I can receive RTTY locally via K3 Line Out or remotely by feeding RRC speaker audio into a sound card at the control site. There's more switching and control logic and support software in there but it's not relevant to what you seem to be trying to do. It's complicated and the journey to get it all working was at least as intriguing as operating the thing. Keep at it. 73, /Rick N6XI On Fri, Jul 31, 2015 at 3:34 PM, RUSSELL J.
