RMV60B no transmitt

Post by redbird »

I need some help on a RMV60B, A model. Mic PTT keys the TX symbol on the
display and a low level transmitt signal, but does not key the PA. The
problem seems to be the transmitt enable line. I can jump pin 6 of J701 to
pin 3 of HY701 and PA keys every time. With the jumper in, I plug in
the programmer and radio does not go into program mode. Another problem is
no PL encode or decode with or without the jumper. Mic hangup grounded causes scan but does mute receiver for tone decode. I am thinking U210 microprocessor on front panel of radio because it enables transmitt and controls tones. What do you think?

Redbird,

It seems as though I answered this one offline somewhere. Did you check the programming and VCO volts?
