[Motorola] M9658 transistor information needed

[n_griggs at bellsouth.net]

This is a UHF unit.  448.7 Rx.  The repeater was working then just stopped.   Several people have worked on this unit before I got my hands on it and finally got it on the air - before it quit.  It worked for 3 months then stopped.  My first hunch was correct in that it was not receiving on frequency since this is where the unit has had problems before.
