[Elecraft] KPA1500 AND THE 403A 1A2R

[Ken K6MR]

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.

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.

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.
