thinking of selling off my systems...just don't have the 'oomph' to keep them up, and the micor is a constant source of headaches (add-in squelch board just goes brain dead and cuts out; sometimes the t/r relay will not activate, even when activating the PTT pin on the external interface...thumping the center board usually brings it back...it has a rushing noise on rf repeat, sounds like a 'woosh' when the machine keys up...). Just running out of patience, and, to be honest, the whining of users. Get enough of that from the XYL and work colleagues. So, what I have is: 1 220MHz Micor repeater conversion running at 10W 1 TE Systems 220 mhz 120w mobile amp (running at 50% power...NEVER gets hot) 1 6 can duplexer (Decibel products)...don't know the model, tuned to freqs 1 6 can Angle Linear duplexer w/2 can rcv preselector and PHEMT preamp, tuned to freqs. 1 Tram 1494 antenna cut to xmt freq. 5 DMK dongles w/usb cables 100' LDF4-50A Heliax divided into a 25' and a 75' section, with andrews N males on both ends 1 N-N polyphaser 1 900 mhz maxtrac conversion to 902 Rcv 1 900 mhz spectra conversion to 927 xmt As a package, now..the angle linear duplexer is sitting in CA at the factory....and can tell you that it is 1) not cheap, and 2) is the best that's out there. But, only asking the invoice price on that part. Offers...??? Systems are located in between NY and PHL. Pick-up only. You
1) Remove all the boards, including the cards in the control shelf. 2) Spray all MICOR board connector pins with the recommended suite of Caig Labs "DeOxit" sprays, one to clean, the other to protect. http://www.caig.com/ 3) Re-insert boards. 4) Be happy. Bote

I like Caig DeOxit.....but there is some evidence that is does not age well. I recently re-build a Micor that was cleaned about 15 years ago with what was reported to be Caig DeOxit. The pins had a "gunk" buildup that was non-conductive, and I posted about that and got several replies back that they have seen De-Oxit do that over a long period of time. Thats pretty non-scientific research but it's what feedback and expierence I got at the time... After cleaning all that off the pins (which took some time) I then treated the pins with Stabilant22, which I am told is the only motorola approved pin treatment. You can find it online, its a little pricy but so far has worked well. A little goes a long way, its mixed with a 99% isoprobyal alcohol (sorry for the spelling). But I agree whole-heartedly with Bote, clean it, tune it and it will live another 20 years and outperform much of the new stuff, not to mention you can usually find all the replacement parts you need surplus for little or no money.

Insert 3.5: Replace PTT relay on mobile system board, preferably with a solid-state device. As far as users whining, offer to refund their dues, that usually shuts them up ;-) --- Jeff WN3A

The way of the world. Thanks, guys, for your suggestions...taken them to heart, and am working on it as we speak. It ain't gonna get the best of me (he said, with a demonic look in his eyes....). -- Bryan WB0YLE In this world, you must be oh so smart or oh so pleasant. Well, for years I was smart. I recommend pleasant. You may quote me.
