KPA1500 AND THE 403A 1A2R

[Richard Zalewski]

Just wondering if anyone is using the 1A2R from 4O3A with their KPA 1500.
Seems like a great solution for my Flex6600M and KPA1500 combo.

I think the biggest obstacle would be switching the band data to the  
KPA-1500. If you operate 2BSIQ it really pushes the amp duty cycle,  
especially on RTTY. The Flex amp is already set up for this.

Excellent point on the band data issue John.  I was holding out for the
Flex amp but no tuner is an issue for me with my low band antennas.  If
they ever put the tuner in the amp I will consider it.  Will have to study
the band data issue.

I don’t specifically use the 4O3A switch, but I do have single amp SO2R using a KPA1500 and two K3s.  I’m using a MK2R to generate the band data with a set of 4 TopTen A-B switches to handle the RF switching.  An Arduino handles the AuxBus messages between the amp and the radios.



The amp does make a bit of fan noise on RTTY when dual CQing, but otherwise works just fine.  I have the amp in a closet so the noise is not a concern.
