Fred, Elecraft has the KPA100 which offers automatic bandswitching and a lot of other features. It can be driven by the barebones K2 quite nicely.
Add an EC2 enclosure and you can have the KPA100 external and still with all the function of the inboard unit - your basic K2 will still be ready to 'grab and go' as a QRP transceiver. Pricewise - yes, it may seem like a lot in one 'ball of wax', but if you price the components to build any external amplifier and include the enclosure and other hardware, I believe the KPA100 price will be on a par with others. OTOH, you may wish to wait until Dec 15 when the restrictions on external amplifiers that can be driven with less than 50 watts is lifted and see what appears on the market. But I would bet that none of them will have the operating conveinence of the K2/KPA100 combination - not to mention the addition of the automatic tuner the KAT100 if one does not have resonant antennas for every band. 73, Don W3FPR > -----Original Message----- > > Are there any 50 or 100 watt external amplifiers, > that a barebone QRP K2 can drive?
