This is typical of HF receivers from years past-- meter indicates increasing AGC as you reduce the RF gain; only stronger signals will flicker above the meter's reduced sensitivity indication.
Supposedly this could be changed in a SDR radio. Some have requested that the meter not respond in this traditional fashion, but instead always measure the signal levels "at the antenna terminals" regardless of the RF Gain setting. Your meter reading may also be affected by attenuator and preamp settings (ATT and PRE), but there is a config option in the K3 to ignore their effects. However, this 'absolute' setting is still subject to the RF Gaiin control effect that you noted. 73, Drew AF2Z On Fri, 04 Apr 2014 21:24:15 -0700, you wrote: >Ive just completed building my K3/10 (S/N 8115)!!!
