Hello everyone.
I've got a problem with my Realistic TRC 453 (simillar to Uniden PC-122 Radio).
It has no modulation on AM mode (carrier only), but on SSB mode everything is allright and modulated.
So I am asking you. How I can fix it up?
Driver, and PA transistors are OK.
I picked a new capacitor 47uF near to the NE612 modulator and trying to resolder the area around.
Turning the VR of AM mod changes nothing.
:headbang
Any ideas?
73!
