Just spent quite a bit of time looking over the past 3 years of
archives on the AL-1200
They indicate:
1)40/80 RTTY operation at near full power burns up tank circuit
components
2)10 meter efficiency is poor with little chance of getting full
output
3)Parasitic oscillation problems haven't been solved
4)Noise from fan intolerably loud
5)WARC bands are a compromise because of tuned input circuitry. One
has to mistune it to get both WARC and adjacient non-WARC bands.
Is this info still valid? If it is, it says manufacturer's apparently
never test their
products. I don't understand why anybody would buy this unit.
There doesn't appear to be any currently made amp out there that is
instant on, quiet, stable, WARC band friendly with 1.5CCS output
