Has anybody done this mod? Pro-2006 s-meter ?

Parts:
10Kohm 1/8w resistor, 0.1 uf capacitor

Locate D33 on the linear PCB. Solder in the 10K resistor to the ANODE
of this diode. Note this is not the same as TP2. Connect a wire from
the free end of this resistor to a rear panel jack (RCA). Solder the
0.1uf capacitor from the jack's center terminal to ground. Output on
this jack follows the AGC voltage. Negative for no signal, goes
positive when a signal is present, increasing with signal strength. A
1Volt full scale panel meter makes a good "S" meter

has anyone tried to do this particular mod to the 2006?I am curious as
to if it worked and how well.The mod says to hook the resistor up to
the RCA jack but where,in the center or on the lug that's off to the
side.that comes off the jack?am wondering if the 9 volt battery ground
would be sufficient,I tried it myself but I get a steady signal on the
meter and sometimes it goes up when it "hits" but the stronger signals
go backwards??if that ground is wrong can anyone tell me where would
be the best place to ground the capacitor? also it states D33 is not
the same as TP2,is D33 actually on the bottom of the pc board or ??any
help appreciated from an "expert" that has done this mod to thier own
2006!!

Thanks in Advance,Tom

Hey Tom,
I haven't posted to this group before, but I have done this mod.

First off, I made mine completly internal, with a variable resistor
not just for calibration, but for signal tracking. Anyway, it's been
awhile, but I do remember that when I first did it I had the same
problem as you, the stronger signals go backwards. To fix that just
reverse to wires going to the meter. As for your ground, I just solder
my ground lead straight to the metal chassis, and haven't had a
problem yet. As to the last part about D33 and TP2 its been so long
since I've had my 2006 apart that I can't remember. When I have a
chance to pull it apart I'll let you know.
