basically want the rated output or actual average output for the mrf 422. looking at the klv model being solid state with 2 mrf 422 transistors in it and was curious what this box really does on average. so any help appreciated.

I got a KLV550 and its got 2-sd1407 pills they're rated at 100 watts with 2.5 watts drive,typically only 80% of output.They easily put out 300 watts with 5 watts deadkey in so watch that swing,and in excess of 400 with 15 watts SSB on position 6.Those mrf422s are 150 watts with 15 watts in,much much more rugged.

motorola is getting out of the hf RFtransistor business,they're more into uhf and microwave.RFPARTS hassome but they are EXpensive,the 1407s are over 50bucks a piece,they test their transistors at 80% usually, so 100 is 80%,125 is 100%.
