[Elecraft] AF1 filter

[Gary D Krause]

Thanks for the input, Terry!  I operate mainly CW also but, I also operate SSB 
a little.  I have an Autek Q1-FA audio filter and it works fine but, the K2 
doesn't have enough mojo for my external speaker.  I noticed that the AF1 has 
a built in amp so I'm hoping that will work.

Gary, N7HTS
