Another 48-482
#18

If your FM stations are coming in at the right places on the dial, then the oscillator is probably right on, so you don't want to screw with that trimmer. If not, then you can use that station to tune the trimmer until it comes in where it should. You will also need to adjust the RF sections for maximum volume. You can also peak the IF using the jumper on the FM-1000 socket, and a regular signal generator. I suggest using a good digital receiver to double check the signal generator output. For FM it should be 910 KC. This uses the other trimmer screw on the IF can, so BE CAREFUL of that or you'll screw up the AM and SW. Look at the picture to make sure you are using the right trimmer on the IF, as well as the ones on the tuning condenser. Good luck.
