[Elecraft] KPA500 question

Slava,

I have the KPA-500 and an AL-1200 amp.

The KPA-500 is used most of the time.  When your working dx all you want 
to do is get through one time.  The KPA-500 does that perfectly for me.  
Its so easy to bounce around from band to band chasing dx with the 
K3/P3/KAT-500/KPA-500 combo as compared to using the AL-1200 which 
requires re-tuning on every band change.

On the flip side if you like to contest 1500 watts probably helps in 
that you want to be the first call through to a dx station so you can 
move on to the next qso, quickly.

If I didn't enjoy contesting I would sell my AL-1200.  However, I am 
seriously considering selling my AL-1200 and getting a 2nd 
KAT-500/KPA-500 to go with my 2nd K3 I just purchased.  From a pure 
control stand point for SO2R a pair of K3/KAT-500/KPA-500's would make 
things very smooth and easy.  Just sit there and operate.

Of course if power is real important and $'s are not an issue an Acom 
2000a, Alpha 9500 or SPE 2k-FA would be the ticket.
