The mods to allow the receiver cards to accept a more common level of COR voltage are straightforward, take less time, and probably cost less than building up outboard logic level converters.

I really like them. They just work. Very easy to interface to, and the voting seems much better than most of the others. I know of a large system that still has a Moto Spectra-Tac on it, and he had

I have a few sites doing this. As long as the frequencies are CLOSE enough. They have to be close enough that the passes and the notches are wide enough to cover both pairs. Use a single 4 cavity or 6

Now that's been several years since they closed their doors anyone heard if the "files" were kept?? My dream (yea, I know) is some of the ex employees got together to start up a new company that

Lots of SMDs on the (OEM) board so you may need a wave machine or lots of pacience, LOL.? But ye,s it would be nice to start it up again. Same goes for the Doug Hall voter. -- - Regards, Karl

You are correct, Jim.??? I still should get my hands on a GE shelf (with the cards, ot course) and dig into it. I'm a documenation guy so I might even do a paper on it. -- - Regards, Karl Shoemaker

1600Hz for a SpectraTAC? That's definitely an SP thing. They have the option to jumper for 1950 or 2175Hz, but 1600 sounds like some SP thing. Maybe for older RCA voters? I'm pretty sure I've still

With as inexpensive as it is to get PC boards made, perhaps you could ask him for the appropriate PCB files and have your own made. Chris -- Chris Baldwin, CETSr. (KF6AJM) Trustee - MetroNET Cal.

Joe it might be easy to disable those tones.? For the SpecTac receivers I have on the 20 repeater they work very well with the SNV-12. Someone posted to purchase the older used ones.? Anyone have a

Larry, I even kept a box of tubes for stuff like that. Years ago Ray Kresick ran a "tube bank". I have not idea what happened to it. -- - Regards, Karl Shoemaker To contact me, please visit SRG's web

I'd like to see the schematic drawing or a least a block diagram of you folk's design as I'm open to new ideas and ways to do it. What a Team :) -- - Regards, Karl Shoemaker To contact me, please

I have a DB4060WOC-B VHF and a Telewave UHF BPBR duplexer for sale. PM at this email or wb5itt at att.net if interested. Chris WB5ITT

New, never installed, local club bought it 10 years ago, and project never got off the ground. no box, but new, from the factory. Includes the rack mount enclosure, DR-1000 DVR, DL-1000C audio delay

What modes for narrowband I have one new in box I would like to use. Unfortunately the builder stopped making them when he ran out of circuit boards. I did try and buy some more in 2011, and that was

Karl I guess you missed that the RS50 fried, quite badly and no amount fusing would prevent being blown. The county now has commercial surge protection on the mains, When I was still working, another

The only problem that I can remember with interfacing the SpectraTac receiver to the SNV-12 voter was the status tone. The SpectraTac sent out a 1600 pilot tone and the voter was expecting something

Sounds pretty bullet proof. You can't knock those old Micor receivers. -- The Real RFI-EMI-GUY

Definitely an interesting device. Would be helpful if schematic service manuals were on line.? It got to be a bidding war so I backed out when it looked like it might well exceed the price of a new

I helped to build a few JPS SNV-12 voter systems years ago.? We used Motorola Spectra TAC Receivers (narrow banded, Comm Spec filters, don't ask not my decision) and it worked well.? It took a
