Easiest is to just make a small loop of wire at the input cable to the counter and hold it near the CAR OSC tube in the right rear corner of the TR-4C. Set it to 9.0000 MHz, but the final adjustment is made by "centering" the oscillator between the two sideband filters, i.e., adjusting the trimmer carefully while switching back and forth with the sideband switch. You should be able to find a point where the hissing noise is the same "pitch" when switching back and forth.
