I'm doing a poll on HF Amps 

I would like to know which HF amp you are using and if it is CAT controlled.

Let me know!

I use the Expert 1.3K-FA amp with the 6500 and CAT control. It is great with FAST solid state operation.  You're on the air with the amp in 10 seconds. I also use an Acom 2000A not CAT control used primarily for contesting.

Flex 6600 with Elecraft KPA1500.

CAT controlled, no special software required. Uses Elecraft USB cable for CAT input from back of Flex 6600 to KPA1500. 

If you op CW, Full QSK, very fast, no TX Delay required, and no relays. 2800 watts of LDMOS devices. Internal auto tuner.

Bill - Can you share how you have them all connected?  I currently have the same setup, but not the KAT-500 which I'm thinking of purchasing.  Thanks.
