For QRSS modes one could use a transistor switch to key the
output. That is how I keyed the output of a DDS synthesizer on
500-KHz for driving my 100w 600m xmtr. Of course the K3 does all
modes on 500-KHz at 0 dBm and that is what I currently use as driver.
You'd need a PIC thingy to do the keying too, though. QRSS isn't only done using on/off keying, it can be done using 5Hz shift FSK.
