[Elecraft] KPA-1500/FlexRadio 6400

[Dave]

Let me rephrase. 

It needs frequency CAT data if you do not want to transmit into a high SWR or wrong band filters, even for a few milliseconds. 

I would rather have my station preset the amp to the proper band filters and tuner L & C before transmitting ANY RF into it. 

This way if I see something on another band or frequency ai want to work ai QSY and call CQ. 

If CAT is available I would much rather use it than depend on RF detection.  I have had the three watt resistor on the KPA1500 heat up and fall off the board rendering the internal frequency counter useless. It took out one of the LDMOS devices.
