It may be "fried" but I seriously doubt it. I was able to work into VK this
morning on 40m
with JT65 and I am now getting 30 - 50 watts output.
The fault may be in the amount of signal WINDOWS 8 is allowing to come out of
the laptop.
I am trying to find if there is some level that is pulled down but everything I
see is at 100%
So far so good. I don't want to get 100 watts out and I think that I probably
don't want any
ALC action while running digital modes. The speech processor actually helps
alittle in my
case.
