[Flexradio] Preamp and VAC on F-1500 and F-5000

Hello Tim While I thank you for the tip regarding using the AGC-T control instead of the NR, I am a bit dismayed that this implies the NR function is basically not worth using. When NR is needed most is not on strong signals but weak ones. Turning back the AGC-T control will reduce the
