How does one remove the antenna/ground connector from a Saber? (the one that is part of the accy connector)
I have a Saber I that I believe to be good with the exception that that piece is missing and I have several other radios that I know to be bad that I would like to scavenge the part from but, my service manual doesn't show the procedure to remove/replace that assembly.
Thanks,
John

Saber Accessory Ground removal
John,
If you disassemble the saber down to having the rear side of the Main Board exposed you should see a flat Gold "U" shaped piece of metal extending below where the "Round Accessory Coaxial Connector" is located. This is where the Public Safety Mic or Service cable would plug/screw in. The RF ground transfers from this Gold strip to the Frame / PC Board through the Cover screw.
If your "Gold Piece" is missing I would suggest removing the main board to get access to that area. This of course involves removing all screws,modules and plugs attached to the main board. Even then you will be trying to install the gold "C" clip flat strip into a recessed area and the strip can bend easily which is bad news. I use a pair of small needle nose to assist in seating the clip. It is somewhat tricky to guide it back in as the gold strip is somewhat flimsy and the fit is a tight locking "C" which engages (snaps) into the raised round portion of the Coaxial Plug. Make sure you fully seat (press in from the rear) the coaxial plug as it may have worked its way out a bit. It just fits loosely in the plastic and the clip actually does all the securing.
Be prepared to lightly rebend the strip if it gets bent out of shape. Also if the part is used be sure it has enough curve to actually catch when reseating it. You may need to put a gentle bend inward on the "C" to make sure it actually has a small enough diameter to grip.
There is one other way to install this part and it would involve further disassembly (removing the knobs ergo switch etc) which is bad news.
Give the above a try and see what happens.
Also on a further note while you have the Main Board removed be sure and check the springy piece which seats against the threaded silver portion that the antenna screws into. These have been known to bend inward away from the nut and give less than proper contact.
I also sometimes clean up the silver surface of the antenna nut just to make sure there is good contact there. Dirt and Moisture may have gotten into these areas especially if the radio has been apart and lying around.
Good Luck!

OK. The gold "foil" piece that comes down from the coaxial plug is there. I need to know how to get the coaxial plug out of one of my "dead" sabers so I can put it in this saber that TX/RX fine. The only problem with this radio (besides the fact that it's not a securenet saber) is I can't view/change the codeplug or use it in an SVA until I get that coaxial plug in place because that's where the programming cable gets its ground and the SVA issue is obviousl.

OK...further info.
I disassembled one here and there is an "O"ring under the coaxial plug that in effect helps hold tension on the gold "C" clip.
I pulled the gold strip in an inward direction (unseated it) and that free'ed up the coaxial plug. I was able to get an exacto razor knife under the edge where it's flat and gently prised up on it. Comes right out.
Reinstallation of the Coaxial plug required a constant force inward on it to allow the "O" ring to seat while the gold strip is reinstalled.
I think you are 100% right about the coaxial plug being the gnd provider in the programming process. Never had one of those problems here though.
I have a problem now with programming my System Sabers in that I don't have a accessory cable voltage bias setup to tell the Saber to redirect the RF to the service cable(homemade of course). I need to add this feature so I don't get the beep-boop when attempting to make Power or Freq adjustments.
If I can find a factory Moto Saber programming cable at the right price I may just buy one of those so I can do a full checkout.
Good Luck again and let us know what you find
