The narrowest filter settings (50 Hz and 100 Hz) are actually steeper than this, and the IIR filters (menu selection) are different, too.
I see all sorts of notes in this thread about S Meter readings. Much easier to turn AGC off and use the dB metering function in the radio. Of course, I admit to bias... 73, Lyle KK7P On Mon, Nov 16, 2015 at 8:38 PM, Dave Hachadorian <[email protected]> wrote: > Is the reference to the DSP filter system or the roofing filter >> system? >> > > It is all about the DSP system.
