[CQ-Contest] Elecraft KPA 1500 vs.OM 2000A

[Jeff Clarke]

Bill,

I know a little about the KPA1500 since K4BAI bought one this past 
summer. His worked fine until about a week ago when it started putting 
out 1/2 power - around 700 watts. I posted a message on the Elecraft 
reflector and this has happened to others. Apparently one of the power 
transistors might be blown. I'm a little puzzled by this because I 
though the protection circuit should prevent this from happening. Anyway 
he is going to have to send it the Elecraft for repair. Luckily it's 
still under warranty.  I've also heard some people complain that the fan 
noise from the outboard power supply is loud.

I've also used an OM 2000A from both WW4LL and at the remote station at 
PJ4G in Bonaire. It seems to be a good amp and we've haven't had any 
problems with it.

Jeff

I really don't care if the amp "matches" the K3S in looks.  Like most of you guys I'm concerned about performance.  Both rigs are equal in price.
