Hello to all, I'm at the stage of inserting my K2 into the VHF setup. I've been using a Ten-Tec Paragon for the last 18 years as the IF stage for my 2 mtr station. The Ten-Tec has two connectors at the back (RCA?) with the function "TX-OUT" and "TX-EN". In normal standalone operation a bridge is plugged in. When using amps, and in my case a XVRT - PA - HF Relay, the TX-OUT is a request for transmit (initiated by the internal combination of the PTT, key(er) or tune button. I use this signal in my sequencer to sequentially switch the final HF-relay - switch the PA in TX mode - and switch the XVRT in TX mode after a defined time delay. When this procedure is accomplished I give an enable (TX-EN) signal to the Ten-Tec to switch over in TX mode. This procedure enables absolute power-free switching. (I never blew any relays, amps and preamps in the last 18 years of intensive use). To make use of my sequencer again, I was looking for this function in the K2. Unfortunately I could not find this closed loop procedure.
Of course I can short circuit the "XVRT-OUT" plug (after a 10 dB pad) from the K60XV module to prevent RF injection into my XVRT. I just don't like this type of solution. I saw an RX 8V signal on the DB9 / RS232 connector (included in the KPA100 option, which I bought but not installed yet), but this signal is not the one I can use as described in my above story. Is there anyone out there who made some changes in the K2 which gives similar sequence procedures as with the Ten-Tec? Thanks in advance.
