[R-390] How to remove RF module?

[Bob Camp]

Hi

Rather than pulling the RF deck (which just creates it’s own issues), inject a 455 KHz signal 
into the IF first. The signal does not have to be anything fancy. Your description sounds more like a 
dead IF than RF. If the IF is ok, you can inject signals into grids in the RF deck without pulling
it.

No signals or calibrator on any band so far. I guess I will get out my ganeral coverage receiver and see if I can hear the crystal oscillator or the PTO. I did download the Y2K manual so have some good reference material.I don't see how the rf module comes out. I do see a couple of screws toward the back but not the others...yet.
