[Elecraft] Re： K2 S/N 05143 is on the air!

Mon Apr 12 10:44:17 EDT 2010

I ordered a KAF2 because I prefer the sound of an analog filter the digital, on CW I find it gives it a funny tone, almost a "twerp" sound, and I do not like what it does to the voices on SSB.  So I went with a normal KAF2 filter system.  I have a DSP filter on my normal rig, and dislike the sound "effects" it produces to people and CW, sound like they are speaking inside a barrel or tube.  But then I am partial to my older Tube rigs that I have restored, to me no better sound on voice then one of those guys..

If you have already had a big linear, you don't even need KPA100.  The barefoot K2 can drive my ICPW1 to 350 watts.  Of course, there are other linears much cheaper than ICPW1.

KAF2 is much cheaper especially in the second hand market.  KAF2 gives you effective filtering for CW at much lower price.  Again, it is some what a personal preference.

I worked a bunch of stations in Florida and W1T off the coast of Maine.  I live in Nebraska.  The K2 has good ears!  Antenna is a 14' vertical with 43 radials.  Mic is a Heil GM-5.

Actually, I'm quite happy with the QRP and I want the Serial port on the K100 more than anything so I can run PSK.  The K100 came with the kit, so I might as well put it to work.
