By this I mean transmit (full transceive as the RX works fine there) at the low milliwatt level out of the transverter port where it would be amplified and filtered. This Class A signal does not go thru the driver and final circuits.

Carl,
Not sure of the topology of those radios, as I don't have one.
However, the TS440, of which I'm very familiar with, you have two places to make sure you're general coverage covers //everything//.
Their is the diode you must clip for MARS/CAP as well as a pin on the microprocessor that is programmed.
I was able to lift that pin and enable TX in the AM broadcast band and below.
It's been //years// since I did that mod. I'd have to go to the service manual since the radio is packed up in the C-Train now.
However, it IS possible to get the older kenwoods of the TS440 / TS940 era to TX outside the stanndard MARS/CAP regions.
Since the 440S didn't have a transverter port, I dunno about that. The 440S would drop power fairly quick when it came to going to the AM broadcast band. I believe the most I was able to get at 800 khz was about 20 watts, peak.
Hope that helps. I was able to find the pin to lift and reprogram via the service manual.
