[Kenwood] Re: TS-940 missing Resistor 152 on IF Board, anyone know why and What is the correct FET direction?

[Garey Barrell]

Jeff -

I just took a look at the schematic that I have for the 940.  I finally 
located R152 (boy, their component designators are all over the map!)

It looks like R152 is there to approximately double the "Fast" AGC 
release time when the AM mode is selected.  Perhaps Kenwood decided that 
the "Fast" time constant was better for AM after all, (my preference) 
and deleted the resistor to disable this function.
