Re: [Repeater-Builder] gm300 with cat200 controller
Dan - Go www.batlabs.com They have info on the pinouts of the 16 pin accy. connector. You need ground from both, of course, Flat audio and COR from receiver, and PTT and TX audio to the transmitter. You may also need a pull-up resistor on the COS line, about 2.5K ohms. Manual for the Cat 200 is at www.catauto.com. It will specify pinout of the connector for hookup. As another poster said, these are NOT rated for high duty cycle, and should be run at about 50% power out on the transmitter. PL is almost always necessary, unless you live way out in the boonies. PL can be programmed into the radios, eliminating having to buy a tone board. I'm sure these radios are not the BEST, but they'll work, and work well. Don't scrimpon the antenna, feedline, or duplexer, though. Read the articles at www.repeater-builder.com 73 Chas, KB3CEZ > Okay guys.

Re: [Repeater-Builder] gm300 with cat200 controller
As someone else already posted, Zone 1, channel 1, is the repeater enable/disable command. If the controller is set for default operation, the command 100110 will turn this channel off, and it won't repeat until you turn it back on with the command 100111. That's about the only command you really need to memorize. If you set the receiver to require PL or DPL, that will keep most of the foolish users off when you're not able to listen. In practice, you'll get very tired of turning the repeater on and off. Get more people interested in it and they too can be control operators. Eventually you'll just leave it on all the time (like 99.999% of all the other repeaters in the world). I have three of these controllers, and two are running with MaxTrac/Radius radios, all via the front panel RJ45 MIC jack. I added a COR circuit (one transistor, one resistor) inside the receive radios which comes out on pin 1 of the MIC jack; that simplifies the wiring considerably as you don't need the accessory jack at all. The wiring is very straight forward. Remember that the GM300, like all of Motorola's mobile radios, is not meant to operate continuously as a repeater transmitter, so don't run it at full output power and definitely add a high volume fan blowing on the heatsink.

Re: [Repeater-Builder] gm300 with cat200 controller
A quick check of the manual online shows zone 1 channel one to be "repeater transmit" What this means (in cat-speak) is that by toggling this "channel" back and forth, you can internally make or break the PTT connection between the repeater and transmitter. That's what you are looking for. 73 Mike KA4MKG Jim B. wrote: > Mike Mullarkey wrote: > >>Dan, >> >>If you are purchasing a controller use the Link Communications controllers. >>RLC-1 or even a RLC-4 is the way I would go. >> >>Mike > > > Well, let's not get into this-vs-that... > > In answer to Dan's question, I have not seen a made-for-amateur > controller that _doesn't_ have a repeat disable function of some sort. > It might be called several things, including transmit disable, path > disable, or other things.

In answer to Dan's question, I have not seen a made-for-amateur controller that _doesn't_ have a repeat disable function of some sort. It might be called several things, including transmit disable, path disable, or other things. But it's there somewhere. That, identification, and a time-out timer are the reasons for having a controller in the first place. In that order. -- Jim Barbour WD8CHL Yahoo!

RE: [Repeater-Builder] gm300 with cat200 controller
Dan, If you are purchasing a controller use the Link Communications controllers. RLC-1 or even a RLC-4 is the way I would go.

This is my first repeater project ever. I am not sure if I have chosen the right equipment or not, but here goes nothing. I have two Moto GM300 UHF radios that I want to use for the repeater. I have been looking at the CAT200 controller for the repeater. I have not found any information on the CAT as far as DTMF knockdown. I want to be able to shut down the repeater from my HT while away from the repeater in order to stay in compliance with FCC in the event that some jackass gets on the machine and starts showing his level of education with language. Anyone have any ideas on the pin connection and if the CAT200 can shutdown the repeater? Thanks for everything guys. Dan Yahoo! Groups Links Yahoo!
