You may have a large voltage drop from the power supply, check your voltage right at the 6700 at various power levels.. PS could be problem but more likely the 12 volt supply cable connectors.

If You put more than 25 watts into your amp, then the voltage should be ok. RF feedback might be causing the problem. Try putting ferrite cores on all cables. RF can get into everything....and sometimes a minor change causes RF to get into places that you would least expect.

I would suggest test it into a dummy load and see if you get the same results, just to eliminate the
possibilities of rfi,

These are all good suggestions. I would do the transmit into a dummy load first to rule out an RFI issue. This could be a bad coax jumper or common mode currents on the coax form an unbalanced antenna.

I had the same problem with a 6300, the fan in the transceiver quit working!
