Most are ground triggered, but not all.  Check before you buy!  I am having good results from an AD5X QSK kit on my Dentron Clipperton L that puts out about 600 watts.  I am not sure that it would switch a more powerful amp, but if you are now at 10 watts, you will probably find a 600 watt or less amplifier sufficient.  However, 10 watts is not enough drive for most amps, so check the drive required before you buy.  I get about 30 or 40 watts out of the 4-572Bs on 10 meters with 10 watts of drive.  Many amps will require less drive than the Clipperton L, so check.

The recent thread on a possible new Elecraft Amp has made me ponder
about TR switching circuits to an external amp from the 10-watt K2.

I'm guessing that for QSK operation, one has to have a TR relay with a
fast transition speed.  And on top of that, the relay contact ratings
would have to handle the expected output wattage.

I've never used an external amp....are they all GROUND triggered for TR
switching?

Thanks
