hi Don, Merv,
thank you for testing with your HC-5 element!
yes I am using the latest Beta firmware. I use comp 20 and mic gain 20.
when I push mic gain up to 60, I get a little more ALC reading, but never
over 7 bars, but not more output. VCE gain is set to 2.0, I have the feeling
that my voice sounds more natural when I don't drive MIC GAIN over 25.
(in monitor). My LP100 wattmeter shows peaks with 100 W out with this
setting. (same as CW) From this point of view all seems o.k. Do you have
any official statement from Elecraft regarding the ALC reading?
