I think the recent answer about ACSB Amplitude Compandered Side Band missed one point. As far as I can tell, a pilot carrier is transmitted in ACSB. This makes receiver afc/lockon possible - which would seem to be needed at UHF (no tuning dial, wide temperature range). Thus reception on a ham receiver might turn up "poor carrier suppresion" (or a whistle if the pilot has been chosen above the intended audio range). Bob Carpenter, W3OTC
