The mod for gen/cov tx for the IC-735 involves removing D33 and D34 from the PLL unit board. You'll have to lift the PA module up to do this and locate the diodes close to J22 Remote control terminal and simply snip one end of each. If you are not sure then be noted the diodes D33, D34 are on the top of the IC8 chip which is on the top of the backup battery cell.(On the right side from this battery is big IC9 microprocessor) Very simple, but it's amazing just how many screws need removing in the process!
