I have now been able to identify the part I mentioned was soldered between the center pin of the
SO-239 antenna connecter and ground lug on the VX-2200. It was not on the parts list or in the
schematic diagrams in the service manual. Apparently Vertex added it recently.
It is a Mitsubishi Surge Absorber. Vertex part number is: Q9000375. From what I have found on
the net, and its color code bands, Red, Grey, Grey, Mitsubishi's number is DSP201M-S00B.
Seems all the UHF VX-2200's I have seen have this surge absorber installed. I have also seen it on a
few VHF VX-2200's which are a few years old. Maybe the latest VHF radios have it now as well.
Thanks to a Vertex dealer for getting the ID from Vertex Engineering.
