looking at radios, I see many different values for the output power; some hand helds have 1.5W CW (morse code?) and 5.0W PEP (max power possible?) while the Bendix-Kings have 16W minimum. Is it possible to increase that 5.0W to something bigger (amplifier inline with the antenna, or larger antenna?), and what kind of range would that give you? speaking of which, I'm looking at this handheld: http://www.aircraftspruce.com/catalog/avpages/icom_a24.php and how good does it look? I'm liking the built in NAV radio, so I don't have to use a GPS as well. edit- what about having a connector to an antenna mounted on the plane somewhere, would that help with the transmission distance? and what about the fact that it is like two radios in one, is the antenna on it just for the COM frequencies, or does it do both sets of frequency?
