[Elecraft] Is it possible to connect a amp to the K2

[Douglas Westover]

I use my K2/100 to drive an ALS-600 with the QSK-5 T/R box
and I can't say enough good things about the QSK-5. It's a
little pricey but it certainly does a great job and coupled with
the no-tune solid state amp its a nifty combo.

No affiliation with Ameritron, etc., etc.
