[BC] 1 kW AM transmitters, old or new solid state

KRSN in Los Alamos had nursed along a used MW1 for years, always fighting failing modules, and the new owners (local couple from unrelated professions) plunked down the money for a Harris DAX-1, tiny little PWM transmitter that it is. They have only had one problem due to early on failure, and it has run for several years without stop. It would trip off sometimes on high modulation peaks due to the crappy match, so they backed off the modulation and it is solid. They keep the limping MW1 for a backup, but it hasn't seen power since the DAX moved into the bottom of the audio rack beside it. I know the folks are very happy with their decision, as the transmitter is no longer their weak link.
