The Quantar wildcard functions are software defined in the station's programming. Inputs and outputs [hardware I/O] can be part of what you create in the wildcard programming. These inputs and outputs are supported by hardware on the station's wireline interface board. There are two types of wireline boards, 4- wire and 8-wire. The 4-wire board supports the basic wildcard mode and the 8-wire board supports the enhanced mode. There are also different board revisions. Early boards have EPROM based firmware. Newer boards have flash memory and support firmware download. Ideally, if you are retrofitting a wireline board into an existing station, the firmware versions should align. Bro-Comm has some Quantar wireline boards listed on ebay. --- - --- In Repeater-Builder@yahoogroups.com, Paul Metzger paulmetzger@ wrote: Hello all, Might any of you be willing to part with a Quantar *WILDCARD* board?

[Repeater-Builder] M7716 supplier needed
Hello everyone! I am in the process of building a repeater system for the National Boy Scout Radio Station in Dallas, and the audio board calls for a M7716 Micor squelch chip. Since our organization works off of donations mainly, I have to work with what I have. I haven't been able to find it anywhere these days, and was wondering if anyone had one (two ideally, one for a backup), that they would be willing to part with, or, perhaps someone that has an old stock of them? Any help is appreciated. 73, Eric

[Repeater-Builder] Re: In Need Of A Quantar Wild Card Board
Quantar 101: Introduction to Wildcard programming. If you are going to attempt to utilize Quantar wildcard functions you must first arm yourself with the necessary manuals. A good starting point is the Station Instruction Manual, 6881095E05. There are two sections in this manual that are of particular interest. In the section behind the Station Backplane tab you will find the pinouts of the connectors. Connector 14 [6809/MRTI - 25 pin] can be used for many things such as a phone patch, link radio, or external controller. Connector 17 is the big one, 50 pins, and has duplicates of the wire line connections [RX and TX audio] as well as the I/O's. Wildcard I/O's are part of the I/O's on this connector and include transistor buffered inputs and outputs, opto-isolated inputs and relay contact outputs. The circuitry for these wildcard I/O's exists on the wireline interface board, hence you must have a wireline board in the station if you want to use wildcard functions. The 4-wire wireline contains enough I/O's to support the Basic wildcard functionality. The 8-wire board supports more I/O's and the Enhanced wildcard functionality. It should be noted that very early station firmware [e.g. circa 1995] does not support wildcard. Some of the I/O's are dedicated; most are 'soft' - their functions being determined by station programming. Some of the programmable I/O's are assigned predetermined functions such as RD Stat [essentially COR] and external PTT in the default station codeplug [default = as shipped for conventional operation] These default functions are described in the System Applications section of the instruction manual. You should study this section thoroughly as a starting point to understanding how to use the station's I/O and wildcard capabilities. This section also gives some examples of how to make changes to the wildcard programming. Beyond that you will need the Quantar RSS User's Guide, 6881085E35. This is where you will find an explanation of how to set up the wildcard programming. Wildcard programming involves the creation of State / Action Tables States can be driven by input pins. There are also many internal station states such as CUR CHN, RX PL DETECT, or MCS USER. Likewise, Actions can control an output or they can be such station controls as CHN, MUTE TX, or REPEATER KNOCKDOWN Essentially the Quantar wildcard programming is a sort of internal computer language capable of Boolean operations. Very powerful. If you understand computer programming even a little, it's easy to make the Quantar stand up and do tricks. If not - well the whole wildcard thing will be very confusing. The state / action tables are where the functions of the inputs and outputs are detemined. For example, the default EXT PTT table configures a certain input pin. The action for the active state of that pin is defined as key from WL and the inaction is defined as dekey from WL Input and output pins can be configured individually or in groups [where pins are assigned binary weighted bits]. Event flags can be set and reset to allow passing status from one table to another, etc. What you can accomplish with the Quantar wildcard programming is pretty much limited only by your immagination --- In Repeater-Builder@yahoogroups.com, Brian [EMAIL PROTECTED] wrote: Which connector is used?

Re: [Repeater-Builder] M7716 supplier needed
Moto used two or three different numbers for the Micor squelch chip, all of which are interchangeable. You can salvage a chip off any audio-squelch board (but I wish you'd do the cannibalization to a mobile board as the base station and repeater boards are not as common). See http://www.repeater-builder.com/rbtip/micor-index.html http://www.repeater-builder.com/rbtip/micorsquelch.html And you can use a complete Micor audio-squelch board intact - just provide a source of 9.6v (but it will work just fine on anything from 9 to 10v, as long as it is stable and clean), discriminator audio, and a pair of 25K pots (I've used 50K pots, a much more common value, with no problems). I've seen complete tested boards for $5 on eBay. Note that the PL decoder plugs on to the audio-squelch board. Mike WA6ILQ At 03:48 PM 09/10/07, you wrote: Hello everyone!

[Repeater-Builder] Micor crystals
Hi Folks, Wanting to order crystals for my Micor repeater from ICM, but unfortunately my work schedule and their operating hours is not jiving. I see they have some online stuff, but just not sure what I need to fill out. I found this page, http://icmfg.com/order_tcxos.html but not sure if that is what I need nor what to fill out here.

RE: [Repeater-Builder] Micor crystals
Robert, What I have done in the past is send in my old elements with a letter detailing what it was I needed to have done. (i.e. re-crystal and fully compensate) When they came back they were exactly what I needed... If I remember correctly, cost was about $55 for each element.

We are running a arcom 210 controller thanks in advance and 73's VE6IVN Ivan But for discussion's sake, I'm wondering what you found wrong with them, Mike. I didn't build it, but one of our club's early 440 repeaters (a LONG time ago) was a pair of Tait mobiles, and it ran fine for something like 3-5 years. The radios are still in their custom rack panel downstairs in the club's storage area... my basement, and I've used them with a duplexer for a quick-and-dirty full-duplex UHF link two years ago, and then shelved them again. They're tanks... and just keep running. Someone before my time tapped them for PTT/COS and put a little board they made in them to amplify and de-emphasize discriminator audio they tapped and installed into those DB-9 holes I mentioned to Ivan. The only bummer is that they tapped a real COS and it's not muted/gated audio, but that's fixable if I ever need them again for another mini-project. I had a couple of the LTR 220 MHz mobiles without the accessory DB-9 connector and accidentally blew a chip hunting for a CTCSS-follow line in one of them... oops. Probe slipped. I had figured out how to program them for ham 220, using the LTR channel ID's, well at least the receiver of one and the transmitter of another, and was going to hook them up to a 220 antenna for a poor- man's 220 repeater (not for the club, just a backyard project). Anyway, never had any problems with the four of them that are floating around here other than blowing that one up. And that was my own fault. Wondering what you ran into. Mobiles are never good repeaters, but... these mobiles work just fine... -- Nate Duehr, WY0X [EMAIL PROTECTED]
