I just bought a Malaysian cobra 148gtl. It is dead keying 5 watt but no modulation. Any ideas where I should start trouble shooting at?

I have changed the mic, turned the mic gain up and down, check the modulation on both am and ssb, no modulation on am, nothing at all on ssb. I did try the pa, I had audio using the pa. This radio seems to be stock.

Check the wires on the mic jack and mode/pa switches, may have a bad solder joint.
