Hi Bill, Flex did it right and understands AM! When in AM 100% modulation peaks is 4 times the carrier or twice the voltage and current on scope with symmetrical modulation. So it is simple, if you had a 200 watt final you could go up to 50 watts of carrier and modulate it 100% with a 200 watt PA. If you had a 100 watt final and ran it at 100 watts you will have no headroom for the modulation, you would need a PA of at least 400 watts, that is symmetrical modulation only!

Now, I have deliberately set my swr way up high yet the meter tells me it is fine. IT IS NOT. Good thing I have an swr meter on my external tuner and my Amp meter and my sit alone meter. Second, In the set up program it has set my AM carrier for 25 watts yet the Manual has it has 100 watts. Anyone know why? AM is my mode of choice. I do not care how much space it takes, it is the Greatest Mode. lol Thanks Bill _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/ _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
