Re: [Repeater-Builder] Remote Receiver site
We are using Motorola CDM-750's for our sites. Mount both radios to a 1U 19 rack shelf, and using a 4 hole saw, cut a hole below the TX radio and mount a 4 Dayton 24vdc fan, they run forever! We simply use the Motorola R.I.C.K. for our controller so to speak. Simple and reliable. With the flexibility of the CDM's, we program them for ignitiion sense on/of switch so they come back on automatically after a power outage. We can also use the controller at the central site to turn off the requirement for PL at all remote sites with one simple command. Simply program one pin for PL CSQ Detect on the receive radio. Program your radio for PL tone receive only, then leave the radio in monitor mode (yes, if you lose power it will come back up in monitor mode). This way the site hears all traffic, PL or no PL. Then, program the TX radio so that a pin controls the PL encode and feed the PL CSQ detect into the PL encode control pin. The link radio will TX a PL if a PL is received, and will not if none is received. Back at the site, program your receive radios the same way as your receive radio at the site. Then you can feed your CSQ PL detects from your sites into an or logic switch so that if it receives a PL from any site, it sends a single PL to the controller. We ended up using the 420.xxx and 425.xxx link frequencies, though, to try to alleviate any interference. The CDM radios (if you get the right one) will do 403-470 MHz without a problem, no mods needed. So far we've been using these for about 4 years with no problems whatsoever.

Re: [Repeater-Builder] Remote Receiver site
GE MVPs are the best answer I've found hands down. Swap a VHF RX in a UHF frame. You can use a MastrII or ExecII for the TX site and it's all very neat. Even cooler - MastrII RX and TX's convert to 220 pretty easily. While the conversion is not for the faint of heart, 220 links are cool.

[Repeater-Builder] Remote Receiver
Thanks to you all for good advice. The project is to have a VHF receiver (remote receiver), a UHF link transmitter, a UHF link receiver (at the base repeater site), and probably a voter. All of this is in ham bands. I am getting the idea that good choices for the radios would be MaxTrac, Radius, or GM300 radios. These are available for about $200. I am reluctant to include SpectraTAC because it seems to come in a bunch of modules, and I don't understand which ones I would need, and I suspect that when the pieces are ll included, it would be more expensive than the other radios. Questions: a) Are there specific radio models to avoid? b) Are there specific radio models that are particularly good for my application (easy to interface, easy to program, good performance, etc.)? c) Is there different specific Radio Service Software for each model radio? Are these DOS programs that require a native DOS machine? d) I see some Midland VHF (71-3051B and 3032B) and UHF (71-5051B and 5052B). How do these compare with the Motorola radios? Your opinions and experience will be much appreciated. Thank you. John
Re: [Repeater-Builder] Remote Receiver
I like the GM300 16 channel the best. Some of the other Radius and Motorola radios that look the same have a 5 pin accessory connector with less flexibility. Likewise the 16 channel GM300 has more programability on the 16 pin accessory connector than the 8 channel. Now, the 8 channel is a lot cheaper usually, and probably would do anything you need. I stockpile radios in advance of a project, so have stuck to the 16 ch to make sure I can do whatever I need to with them. I've bought about a dozen GM300 16ch UHF on Ebay in the last year at anywhere from $80 to $140 -- one need an IF chip replaced ($20) and that was the only problem with any of them. I MUCH prefer the 10W version, which is often cheaper but harder to find. I almost never use a GM300 in an application that uses more than 10W and they run nice and continuously at 2.5W for a link transmitter as well. The GM300 does use DOS-based RSS that will run under windows, but it can take 10 minutes to read or write a codeplug and sometimes things fail... I avoid that. I just boot my shack PC - a Celeron 2.6GHz machine off of a FreeDOS live CD and run the RSS off of a small FAT16 partition I keep on the PC's only HDD. Models to avoid -- use the info on repeater-builder and Batlabs. Don't accidentally get a GM300 that's narrow-band (unless that's what you want -- never know an ham to want that), and watch the 45W units if you're going to use the transmitter. If you need 5W, get a 10W radio, don't crank down a 45W On Apr 23, 2009, at 1:42 PM, John Transue wrote: Thanks to you all for good advice.

All sites will use the same PL for repeater access, so I'll end up with wide-area coverage (or, in my case, HT access county-wide) with minimal expense, and it is LID-proof for the users. If you are using reed type decoders there is a trick to allow you to wire two reeds into it and get an ORd action. That would let you advertise, for example, 100Hz (the voted tone), yet have 146 for testing one site, 131 for another, etc. Mike WA6ILQ

My first triple receiver repeater used a relay race voter (the first squelch to open locked out the others). After we taught ourselves that a race voter wasn't practical we used a poor-mans voter - we used 100hz for the receiver that was at the transmitter site, 127 for the west receiver and 131 for the east receiver. Later on we got a real voter. I have a UHF Mastr II. I guess one approach would be to swap out the receiver for a VHF receiver and use the UHF as the link. One of you has done this with good result. If you have a line of sight situation you don't need much power. A 5w MVP feeding a beam will talk across town just fine... How long is the link? You might get away with the 1/4 watt Mastr II exciter and beams on both ends. And if you know someone with a welder you can make the beams. See http://www.repeater-builder.com/antenna/420-welded-yagi.pdf I also have an ACC RC-85 controller. I could use this with a VHF RX, a UHF TX, and have a UHF RX at the base. Waste of a good controller. Use a NHRC4 kit. Does the link TX have to identify (amateur service)? I believe it does have to. Is there a way to avoid having extra IDs when the link is active? Well, I guess once every ten minutes isn't much of a problem. 35 years ago Cactus handled that problem. They do the ID at 1064hz (so it won't affect any downstream DTMF decoders) and notch it out at the receive end using an audio notch filter.

I think I like the flat audio on the remote better, but that makes it CSQ, so I keep the squelch a bit tighter AND it's not a a colo-site, so the RF noise around it is residential. Thanks for sharing your configuration.

[Repeater-Builder] Remote receiver suicide control
I am also working toward a multiple receiver voted system and have a question.

It could probably be used for what you want. There are other DTMF decoder units around also. For my application I'm wondering about how to interface the DTMF decoder output to permanently kill power to a site. I'm thinking I want to have it do something like deliberately blow a fuse... but maybe there are better ways to handle it. Paul N1BUG Yahoo!

Re: [Repeater-Builder] Remote receiver suicide control
Paul, A mechanical latching relay uses no power except when changing state, and could be used to drop the power to the whole package.

Mike, Paul, Mike, Martin, and others... Thanks for the ideas. I will try out a couple of them and then make a decision on exactly what method to go with. I had not thought of using a latching relay.

It can be used for a quick and dirty voter. One problem is when both receivers are picking up the signal and the primary receiver is not as full quietning as the other receiver. You get a lot of noise from that receiver where it would be clear audio from the second receiver. This can be helped by setting the squelch tighter or by using differant subaudio tones for the differant receivers.
Re: [Repeater-Builder] Remote Receiver
I used to play PL tricks, priority tricks, etc... FINALLY bought a voter. Now I'd never go back. Of course, what I'm about to say is more pronounced at UHF than VHF, but I've found all kinds of areas where slightly weak picket fencing etc. has magically cured itself with a proper voter in place. I'm sold -- but it does cost money to do this, and I understand financial constraints. Another plug for the programable radios I'm using -- the R1225 has a built-in controller that works great for the link. I've set it to not encode PL when IDing and to suspend the ID on COR. For anyone about to ask the hard questions about using it as a link, yes true zero hang- time on that unit.

RE: [Repeater-Builder] Remote Receiver
John, Tom is right, and this is a quick and easy way to add a single-site remote RX. But like he said, your users will need to be aware of where they are (physically) in the repeater coverage in order to access the proper receiver. I do know of some systems that don't use a voter - the remote receivers are located at the edges of regular coverage, so the effects of heterodyne is minimal. I guess it all depends on how much engineering effort you want to expend on the system, and maintenance you wish to perform once in operation. A voting receiver system is (IMHO) top shelf, but it does require more engineering and maintenance. The benefits are that it is totally transparent to the end users. The cost of a voting system really starts to show based upon the way it is linked back to the main site. RF is the least expensive, but for the typical amateur repeater system, you'll need dedicated link radios and antennas at each remote site, plus the added receivers and antennas at the main site. (I like the one suggestion of making a GE radio into a cross-band repeater, receiving on the repeater freq and transmitting out on a different band.) Some guys are starting to use VoIP for links (discussed earlier on this list)... or the next step up is dedicated T-1 landlines, which have recurring monthly costs associated. For the system I am building (my 440 machine), the county radio system is allowing me to use up to 3 voice channels on of their microwave backbone at no cost to me. So all I need to acquire/install/maintain are the receiver units at all the various sites, and the voter/comparator at the main site. All sites will use the same PL for repeater access, so I'll end up with wide-area coverage (or, in my case, HT access county-wide) with minimal expense, and it is LID-proof for the users. Like Lance said, receiver shelf units are in the $100 range, and the comparator shelf goes for about the same price or maybe a touch more. SQMs (Signal Quality Module) for each receiver (for the comparator shelf) are going for about $40 each, and the necessary manuals can be found as well... I just wish I could work out the same linking arrangement for my 900 machine... but it is not sited at the same tower. ;-p Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com On Behalf Of TGundo 2003 Many systems will use a different PL for different receive sites to get around the need for a voter.

Re: [Repeater-Builder] Remote Receiver
John, I've just started this. I have one remote package out now, and another on the way. I'm using Motorola R1225 and GM300 radios for everything. I'm in the 70cm band, so I use the R1225 as a main repeater exciter and receiver, and the R1225 as a remote receiver/link transmitter. The link receivers are the GM300. The GM300s and the R1225s match pretty well. I've had zero complaints with these radios, which seems remarkable since I have been running micors, mitreks and MSR2000s for years. As for a voter, I could not get DHE to sell me one of theirs after several months, so I bought an LDG. The LDG's voting portion works amazingly well to me despite cautions about it. I was a little less that enthusiastic with some of it's interface logic -- a good product, but could have used another revision to file some rough edges off. I would have no hesitations using it again. In testing mode, we've left the hysteresis at 0dB and literally cannot hear it switching between receivers on the repeater output. Best of luck on the project.

I would appreciate any advice you can offer regarding equipment and anything I should be looking for or avoiding. There is no set budget yet, but I expect it will not support new Motorola equipment. We do not have a frequency coordinated for the link, but will do that when I know what band we want to use. I assume your remote receiver installation will consist of a 2 meter RX TX on some higher band. Assuming the link band is 440, one approach would be a duplexed UHF GE Mastr II, Exec II or MVP with the RX swapped out for a VHF RX. Then build a simple zero hang-time COR circuit audio interface. If you need control ID then you can go with one of the NHRC controllers that fit inside the above radios. My favorite of the bunch is the NHRC micro because it can easily fit inside any of them without displacing the stock CTCSS board, which IMO is a decoder worthy of not being replaced even if it means you have to add a separate encoder since they don't (easily) simultaneously encode decode. Add a dual band antenna, crossband diplexer power supply your remote RX installation is complete. Bob NO6B
[Repeater-Builder] Remote Receiver PL
I'm in the early feasibility stage of moving an OEM repeater from single-site to multiple receivers and a central control/transmitter. The receivers will probably be linked to the control/transmitter site via microwave POTS quality audio channels; NO direct DC control. One fairly critical requirement that has me concerned is the need to be able to selectively disable remote receiver PL from the control site. Without a back channel (I'm not sure there is one so I'm planning worst case) to permit the control site to send a PL disable signal to the remote(s). It is also unlikely that the link will pass most (any?) PL tones. So... how might one best carry a PL detect signal along with the remote receiver audio? Restated; PL detection but NOT PL squelch control in the remote. PL detect signal (expressed as an audio tone?) sent to central site along with remote receiver audio. Central site selectively passes remote audio based on presence of PL signal to the voter. Is there an accepted / commercial solution or will this become a project?

Re: [Repeater-Builder] Remote Receiver PL
I agree with Phil, use the PL decoder at the voter. Your remote receiver set-up *should* have enough audio bandwidth to properly pass the PL tone from the users set into the linkback receiver. Doing it this way allows for local control of the PL decoders which means you can select which receiver sites you want in PL.

Re: [Repeater-Builder] Remote receiver
We also use the ID-8 from Comm-Spec on some of our off site receivers and it works very well for us! 73 Russ, W3CH - Original Message - From: Rod Lane [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Monday, November 29, 2004 1:03 AM Subject: RE: [Repeater-Builder] Remote receiver Check out the CommSpec ID-8. It has an inhibit line that you could feed from COR so it won't ID during a signal into the receiver. You'll need to drop the PL encode during ID. Good Luck.
