Greetings All,
I've recently been introduced to the world of 80 meters via my new 40/80
meter dipole and was astounded to find out how many hams are using
Flex-Radios. Last night I was listening to a conversation among several
Flexers trying to help new Flexer set his RF gain. He complained that it
didn't work like his RF gain on his other radios as he was expecting the
Panadapter display to show a uniform decrease or increase in signals as he
adjusted the control.
The last time I asked a question about the RF Gain and AGC I was referred to
a whitepaper on the subject that was quite deep. As I listened to the
Flexers struggling to explain the difference they kept stressing that the
"Flex RF gain is digital and that's why it's different, don't expect it to
work like your analog RF gain". While that is sort of true it doesn't really
explain what is going on. I use my RF gain to get rid of the loud noise
level on 80 meters without affecting the volume of the stronger stations and
it works superbly.
I was hoping someone could shed some light on the subject so that the next
time this comes up I could explain it to everyone's satisfaction.
