My newly acquired 30 year old amp comes with QSK. As there was a different relay than came stock I have to assume the circuitry may have been altered in the past. I have no way to know this.
After two weeks of normal amp behavior I found the T/R vacuum relay had locked in the transmit position. A gentle tap on the NO terminal released it and function is back to normal. Mostly normal as I do find the ALC idiot light is no longer illuminating and the grid metering response appears attenuated but the amplifier puts out full power with absolutely no difficulty in that 35W drive gives 1500 out to the LP-100A watt meter. My question for here is; if the amp is not properly sequencing with the K3, what setting can I change within the K3 to provide more time for the amp's relays to close before the K3 transmits? I remember there was a feature to allow ms changes for QSK in the K3. How do I find that option? And should I decrease the MS time in the K3 or increase it to let the perhaps relay in the amp have time to close first to avoid hot switching?
