craig l232 agc overload
Posted: 05 Jul 2018, 00:59
this is starting to wear me out
normal to weak sigs the radio rx great
get a strong signal and its worse than anything i have heard
pc-582 mainboard schematic included
agc voltage @ d4 cathode 2.47 rising in overload state to 4v+
d16,d17 getting voltage same as above
r42 tested 4.7k good
d16-d19 removed and checked 1n6263 fitted in replace no change so std ones put back.
changed r42 to 15k and its got 30% better but if i go much higher tx goes funny.
any one?
thanks
