Hi Group, Before I retired, the two-way shop I worked for would get Stabilant 22 from our local NAPA store. It came in a kit (cardboard tube) with a bottle of Stabilant 22 and swabs. I'm not sure if it was diluted or not. The price 10 years ago was about $38. We used it on full duplex 800 MHz Johnson radios on the synthesizer shield cover to stop the desense. Worth every penny, and it cure an ongoing problem with the Johnsons before we read an article in MRT magazine.

Tom, Motorola does not now, and never has, recommended DeOxit or any other contact enhancer "gunk" besides Stabilant 22. Up until just a few years ago, Motorola specified Stabilant 22A, under part number 1180369E78, which is a mixture of pure Stabilant 22 and isopropyl alcohol. Today, Motorola sells a kit under part number 1180384V93 which comprises a 5 ml bottle of pure Stabilant 22, an empty 15 ml bottle, and some tiny swabs. The user then puts 2.5 ml of the Stabilant 22 into the 15 ml bottle and adds 10 ml of 99% isopropanol to make a working solution of Stabilant 22A, or adds 10 ml of pure ethanol to make a working solution of Stabilant 22E. Either solution is extremely effective if applied wet to clean connectors immediately before mating. It is also effective in curing intermittent contacts in card-edge connectors in PCs and electronic instruments. The alcohol solvent is essential for the product to work; undiluted Stabilant 22 is ineffective. Drug-store isopropyl alcohol, aka rubbing alcohol, should not be used since it is diluted with water and will interfere with Stabilant's action. The 1180384V93 kit is sold by Motorola Parts for about $47, but is sufficient to last for years. 73, Eric Lemmon WB6FLY
