[Elecraft] K2 v K3

[Gary D Krause]

Hi Bill,

That's a good point.  I guess I didn't really think about that since I've 
rarely noticed it.  Both of my other HF rigs are from the 80's and my K2 #6113 
is the newest that I have.  I'm use to fighting QRM. Hi! Hi!  To me, the K2 is 
way better than my other rigs.  Now it makes me wonder what I'm missing or 
perhaps I should say, not missing, when it comes to QRM.  I love to work weak 
signals and QRP.  I did own Ten Tec rig with DSP for a short time and then 
sold it before buying my K2.  I didn't like the DSP.  If I had a radio that 
made it easier, I might get bored with ham radio.

I keep looking at the K3 but, that little voice inside keeps telling me to 
wait.  I'm not sure why.  I'm widowed, I have not children, I can afford it, 
and if my xyl were still here, she would tell me to get it.  I think I've 
become my own worse enemy! Hi!

Gary, N7HTS
