If you leave the mounting screws loose it should swing pretty good for ya...

Hmmm; this is a tough question for me. The 929 looks like the same chassis/board as the 959, but an AM only version.

If this is true; then unsolder just the one end of R266 that connects to D103 and C233. Then solder the 'banded' end of a 1N4001 diode into the empty hole where that resistor's end was unsoldered - and then solder the other end of that 1N4001 diode to the end of that same lifted R266 resistor end that you pulled up off the board.

But this info MUST be VETTED - FIRST.

Maybe loosecannon or another radio guru can verify or correct this info as correct first. Oldtimer, I would stay tuned and come back to this thread to see if/when this correction/verification comes through. Don't act on the info I gave until/unless it is a sure thing!!!

This should lower your dead key watts, as this is the NPC/RC mod. Only if that info is correct. But if it doesn't lower it to where you need after you turn your RF Power Output knob all of the way down; then VR18 is the one you want to adjust to get 1 watt dead key. Make certain that your mic gain is turned all of the way down first when adjusting VR18.

Robb I tried this but it wont lower anymore than 3 watts ???????????????

I have a In4004 instead of a In4001. Would that work ?
Thanks

First of all, don't do ANY mod until someone can verify that my mod is correct for that radio in particular. Loosecannon or a few others can do that when they read this post.

The 1N4001 is the one to use; the 1N4004 isn't the right part. The 1N4001 cost about $.05/$.25 or so; even Radio Shack carries them if I'm not mistaken.
