[Elecraft] KX3 2m external amplifier

[Mel Farrer]

Any of the older ones rated at less than 10 watt in and a linear version not Class C will be fine.  I have used the KLM, Mirage and TPL units with success on two meters with various rigs both FM and SSB.  There are quite a few on the used market, just make sure it still works as advertised for rated output.  

Good luck.
