[Repeater-Builder] Re: Motorola MICOR Receiver enclosure questions
Larry, According to my VHF PURC5000 manual the connections are: Pin 1 - Gnd Pin 2 - Rcvd Audio Pin 3 - PL/DPL Disable Pin 4 - nc Pin 5 - A+ Pin 6-10 - nc The mating connector is J2400 on the Control Board. I have not opened up my UHF receiver to check and see how the pinouts line up. I would be surprised if they were different. 73, and hope to see you in Rickreall for Swaptober Fest.

RE: [Repeater-Builder] coax length
Collin, I found a nice commercial-quality load (the type that looks like a big heat-sink) on the e-place quite cheap. I'm really happy with it.

[Repeater-Builder] ROIP interfaces
Hello Group, I am looking for options for ROIP interfaces that can be interfaced to base stations. I am aware of the major brands such as Omnitronics, Telex/Vega, CSI and Raytheon/JPS. Are there any other vendors out there that do a decent stand alone ROIP interface unit at a reasonable price? We are OEM suppliers and are looking for possibly two tiers of unit, one that can provide regenerated CTCSS (High end tier) and a more basic unit for possible trigger base applications that we can integrate into our own systems.

I have been wrong many times in the past. Thanks, Collin Most of the non inductive resistors are only that way around audio frequencies. At RF they turn very reactive. You need a dummy load that is RF rated. If you don't run too much power for the coax to handle it, 100 feet of rg58 and the cantenna would make a good dummy load for 140 MHz and up. The losser the coax is (but good coax) the better the dummy load it will be. If you have around 400 to 500 feet of rg58 you can just short the end and have a better match than most commercial dummy loads at 140 MHz and up. Some of the good dummy loads are made similar to the Heath-kit but the 'shielding tube' is formed to be a better match to 50 ohms. Sometimes it is not a straight pipe,but it is curved so it will match 50 ohms over a broad range of frequencies.

[Repeater-Builder] Re: Motorola MICOR Receiver enclosure questions
Larry, I do not have the manual that specifically covers the optional link receiver chassis, which is what we both have. I was using the pinout off the the opposite end of the cable where it connects into the station. There is no reference that I have found any reference to a COS input signal. It appears that the system is expecting idle tone to be present, much like the spectra-trac voting system. We may need to find the manual for the link receiver option, to find out everything the other gentleman was saying about the differences in the audio/squelch boards between bands. I think between us with our previous Micor experience, we can find the appropriate COS and PL detect signals on the A/S board. We may have to do a little digging and use something like a CD-4001 or CD-4011 cmos gate to buffer the signals to prevent loading, but that is not a huge problem or showstopper. Lots of room inside that chassis to work with. I am also inclined to use something like a DB-9 or a round hole mount Cinch style multi-pin connector instead of the ribbon cable. I know Motorola used the ribbon cables for a lot of their cabling in the newer stations, but I still prefer using shielded cable for interconnections. Joe

As I recall, the DTMF must be entered on the repeater port on the NHRC-4 and there is no command possible from the link port.

[Repeater-Builder] Community Tone board question
I think I know the answer to this but I am going to confirm it. The community tone board only filters out what talk group you don't want to hear. And it won't let you if you have multiple groups on the same pair talk over each other. Am I correct on this? The reason I ask is that we have several groups that want to be on the same pair but want different PL's but the machine wont let two people with different pairs talk at the same time if I am not mistaken. We only have one pair for this site (VHF) and they want several talk groups for grounds, maintenance, banquets, housekeeping, ad the front desk. Let me know of I am right on this or if I am being crazy. Thanks Peter
Re: [Repeater-Builder] Community Tone board question
Hi Peter, The tone panel's function is to let each group hear their own users, but it doesn't prevent someone from stepping on someone else when the repeater squelch is already open (as it is when a valid user is talking). Most radios have an activity light that will indicate if the channel is in use. Motorola (and probably other) mobiles usually go into monitor when the mic is taken off-hook, so anyone already using the repeater would be heard. I guess you'd say the panel is a traffic cop but it won't keep someone from running the light. Hope that made sense.

[Repeater-Builder] Re: Community Tone board question
Peter, I will take a stab at this and some of the others can jump in and help out also. Yes, you are correct in your assumption as to how a community repeater works. It is a single channel repeater with the ability to have different user groups that each have their own PL or DPL Tone. The repeater can only handle one conversation or user group at a time. Typically the mobile radios had a wire connected to either the hang up button on the microphone or they used a hang-up box that contained a switch inside it. The way this worked was when the microphone was hung up in the holder, the radio was in PL mode and you could only hear conversations from your group. When the microphone was picked up or taken off hook to make a call, the radio was then changed to carrier squelch mode and you could hear if the repeater was in use by another group, or was available for use by you and your group. If it was busy, you just waited your turn and if it was clear, you were good to go. It was not uncommon to have 6-8 or more different user groups on a single community repeater.
