[Repeater-Builder] Need Maxar/Moxy power connector
Howdy all, I need to find a handful of power connectors for some old Maxar/Maxar- 80/Moxy radios, the ones that have the two larger (0.093 Molex) pins for power and then use smaller (0.062 Molex) pins for the other fifteen test set connections.

[Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups
Getting ready to purchase a TXRX dups for my UHF repeater. Repeater will be running about 100watts into the dup.s. Will be buying new. Suggestions on model numbers to look for? Is the TX/RX brand what I need to be looking at (for the best BP/BR dup.s)? Currently running the Moto series 1500 (BP/BR). Thanks, Robert KD4YDC

RE: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups
Robert, I would have to agree with Chuck, the TXRX brand is hard to beat. Now you want isolation, Just keep in mind that the noise floor is rising and what you purchase today will not be the same as if you purchase it in five years. Bigger is always better and at sites today you can't go wrong with going over kill on the filtering. If you get the standard 4 cavity BPBR duplexer. You can have them add a extra band pass to both the TX RX side for some extra out of band protection. When you get the duplexer add a TX isolator if your repeater does not have one built in like the Motorola MTR2000. Anymore us hams need to keep our stuff cleaner than the commercial guys. For the most part a lot of us do so but there are a few that really skimp and make it hard for the rest of us when dealing with sites. If you decide to go with Sinclair here is one on EBay that looks new and will perform as good or better than the TXRX and is just an option/comparison in duplexers. http://cgi.ebay.com/Sinclair-Q3220C-UHF-BpBr-Repeater-Duplexer-Combiner_W0QQ itemZ280251348599QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l11 16 Happy Holidays, Mike Colorado Telecom, L.L.C Mike Mullarkey 6886 Sage Ave Firestone, Co 80504 303-954-9695 Home 303-954-9693 Home Office Fax 303-718-8052 Cellular _ From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of georgiaskywarn Sent: Saturday, November 29, 2008 6:59 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups Getting ready to purchase a TXRX dups for my UHF repeater.

Re: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups
Robert, There is nothing wrong with the T-1504 series duplexer if it if properly tuned and adjusted, and unless you have money to throw away to bolster our sagging economy you arn't going to accomplish a lot in the process. I just retuned a set of 1504A's the other day for 443/448.325 and got 80 DB of isolation from each side, with an insertion loss less then 1.5 DB. Interconnect cables are easy to make for the 1504's and the service manual indicates the proper length of each cable for the freq. range you want to tune to. It's a lot easier and less expensive to add additional cans for greater isolation or filtering to the duplexer you have then puchase a brand new duplexer. Let me know if you need some help with this and I'll see if I can work something out with you about getting together after the Holidays. Doug (in Jasper, Ga.)

RE: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups
Robert, Motorola sold a gazillion 100 watt UHF Micor repeater stations equipped with the T-1500 series duplexers, and many of them are still working just fine today. I'm curious: What is prompting you to replace your existing duplexer? Is your repeater an original Micor, or some other brand? I ask these questions because I don't see the justification to spend nearly two thousand bucks, if no real improvement results. One option you might explore is the addition of a bandpass-only cavity on each side of your existing duplexer, or at least one on the transmit side to clean up any sideband noise from the PA. Some aftermarket PAs are remarkably trashy, and a bandpass cavity can do wonders to improve the station operation- especially if receiver desensing is being caused by transmitter noise that falls on the receive frequency. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of georgiaskywarn Sent: Saturday, November 29, 2008 5:59 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups Getting ready to purchase a TXRX dups for my UHF repeater.

[Repeater-Builder] How to set up a basic crossband repeater system in Public Service
My local Community Emergency Response Team (CERT) has recently obtained a UHF repeater (ICOM CY-F221S). It has two ICOM F221S radios linked together in a nice rack mount box. It has also been set up with a remote mic and speaker off of the outputs on the chassis back panel. The CERT group is licensed for the UHF repeater frequencies and they are in the public service band. They also have a simplex VHF frequency in the PS band (old police frequency) licensed. They have a number of Motorola HT radios (CP200) that operate on the simplex VHF frequency. They are looking at obtaining additional UHF HT radios in the future but would like to be able to use the equipment they have if they can get it to work together. I am familiar enough with electronics to be able to follow directions, but not enough to design anything beyond a basic switch box. I am a network engineer professionally so I am pretty well versed in those areas, and understand logic control pretty well. I am a technician class ham, but don't know a lot about RF as I have not had that much experience in it. I would like to accomplish the following and would love to receive some guidance from someone who has the knowledge to instruct me: I would like to set up a cross band link for them from the UHF repeater, to a VHF radio: This would allow someone on the UHF side to transmit to the repeater, and also cross-band repeat to the VHF side. The VHF side would be able to transmit on the VHF simplex frequency to the cross band side, and it would repeat onto the UHF side. I realize that this would NOT provide VHF to VHF repeating, and that is okay. I want to provide a way that the cross band link can be enabled and disabled by remote DTMF tones so that the bands can be separated when desired. I already have an old Motorola Spectra police radio operating on the VHF side at the site, and it has a dedicated antenna. It puts out 110W which is way too much for what we need. I was thinking about getting an ICOM F121S radio, Astron power supply, and ICS basic controller board. Using the existing VHF antenna, I would hook up the new ICOM (50 watts or less). Now I just need to tie the ICOM repeater, controller, and new radio together into a cross band system of sorts. Am I on the right track? I need some general guidance that can tell me, try this, this, and this. Here is what equipment you could use, and here is how you could tie it together. I have the schematics for the repeater available to me. If I don't want to spend the money for a new ICOM F121S radio, then what else could I connect easily that I can program and would be able to get at a reasonable price. This is all being done as volunteer service so inexpensive is best, but I want to avoid cheap equipment. Thanks for any help you could provide me, 73 Bryan Carter KE7GVJ Kaysville CERT Administration
[Repeater-Builder] Re: How to set up a basic crossband repeater system in Public Service
You probably already know you need to find tx audio input, squelch gated rx audio output, ptt COS or TOR. COS is carrier operated relay TOR is tone operated relay. Preferably you'll use TOR as the active low output to key the vhf ptt. There's software settings to make these I/O's as you need them. It is necessary to adjust audio levels into out of each radio. This can be done with series resistors or attenuator pads. Chances are you'll need to use caps to equalize the audio as well. Ideally you'll have a service monitor available to check all this. In lieu of the SM, you can carefully compare between the uhf vhf sides for best match of tone quality levels. Wish I had the tech info near me but it's all at work. You might find a way to use the dtmf decoders in each unit along with some type of latching relay to perform your control functions. I'm pretty sure there's I/O for the dtmf decoder available on the accessory jack. --- In Repeater-Builder@yahoogroups.com, bkcarter33 [EMAIL PROTECTED] wrote: My local Community Emergency Response Team (CERT) has recently obtained a UHF repeater (ICOM CY-F221S). .snipped...

Re: [Repeater-Builder] How to set up a basic crossband repeater system in Public Service
Bryan, I can recommend the NHRC-4 controller for the service you want to implement. I'm not sure but I think the ICS-Basic you mentioned is a repeater controller that does not have the second port to control your link. I have built up 3 of the NHRC-4 controller kits and used them in two port service where the main port controls a repeater and the second port controls a simplex radio on another band and can recommend them for this type of service. They were easy to build, and the later control system is very easy to set up using the zone type of control groupings. I ordered the remaining parts from Digikey for my controllers, and the suggested part numbers in the manual work out fine. With a well stocked junk box, you may have a lot of the parts. I did not have to order a single resistor or bypass capicator for my kits. You could probably get started using the existing VHF radio, and if it proves to have too much coverage you could change the radio. When working with hand held radios you may find that the extra power is useful even when the handhelds can't talk back to the simplex port. Being able to copy EMCOMMS even when you can't talk back can be of some use. Finding the correct interface for the radios to the controller can be a pain, but can usually be accomplished. The NHRC controller can handle receive audio that is already equalized, or can equalize the audio from the receiver discriminator inside the controller. Same with the receive audio from the VHF simplex radio. 73 - Jim W5ZIT --- On Sat, 11/29/08, bkcarter33 [EMAIL PROTECTED] wrote: From: bkcarter33 [EMAIL PROTECTED] Subject: [Repeater-Builder] How to set up a basic crossband repeater system in Public Service To: Repeater-Builder@yahoogroups.com Date: Saturday, November 29, 2008, 12:03 AM My local Community Emergency Response Team (CERT) has recently obtained a UHF repeater (ICOM CY-F221S).

[Repeater-Builder] RLS1000B question
I have a RLS1000B connected to a RC210. I have a 220 link radio on the RLS1000B and the RC210 is connected to a UHF repeater. The TX audio from 440 to 220, PTT on 220 (when the 440 is keyed), COS from 220 to 440 (which then keys the 440)is all fine. However I can't get 220 audio back to 440. I checked connections and everything is fine. I plugged the 220 radio directly to the RC210 and works great. I have a plug in line to switch some pins around to make that cable work when plugged into the RLS1000B. Checked out fine. The paper I have on it is real dim on details.

I'm glad someone else brought this up. During my 18 years in LMR, I ran into a bunch of instances where someone wanted to link this to that, or wanted to use a non type accepted radio or wanted to do several other less than legal things. My response was always something like make sure your station is completely legal if you are not the license holder. Don't set your levels by ear, make sure they are set up correctly, even if you have to pay to have it done. Why? Well, if you use improperly set up equipment on a license you do not hold, such as a volunteer fire frequency or the like, you place the license holder in a bad spot should your station happen to be found in violation because of improper levels or bandwidth. Same way with a converted ham radio, modified to operate out of band. The point of my post is to make sure that your actions don't adversely affect the licenseholder's license. It may be really tough to explain to the county judge in your county how your actions caused the county to incur a license infraction with the FCC, or worse, a fine, or the loss of a license. I'd step very carefully here if it were me. In all license services except the amateur bands, just because you can wire it together, don't assume it is legal Mike Pugh

I found a reference to the connector we're speaking of, which mates with connector J601, in Maxar 450-512 MHz manual 68P8103E10-O.

And loss of a license would adversely affect the ability of any PS agency to do their job. You would be essentially putting them out of business. Then, the municipality could come after you for the costs to pay another municipality to cover their area. After all, they only have to pay because YOU made them lose their license, and they are under legal obligation to provide at minimum fire protection (well, at least in PA they are). It can get very expensive very fast. Is it worth losing all your possessions and perhaps doing some jail time over saving a couple hundred or even a couple thousand dollars for doing it right? Also don't forget the suits from anyone adversely affected by the lack of or delayed response from emergency services. They will be in line to sue you, too. And you better pray it's not the county who loses their license - affecting PS agencies in the entire county. I'm sorry... the number you have dialed 9 1 1 is no longer in service. John Smith wanted to save a few bucks. Oh, and if you have a ham license? Write that off, too, as well as any other license you may have held. Joe M.

Don't set your levels by ear, make sure they are set up correctly, even if you have to pay to have it done. Why? Well, if you use improperly set up equipment on a license you do not hold, such as a volunteer fire frequency or the like, you place the license holder in a bad spot should your station happen to be found in violation because of improper levels or bandwidth.

[Repeater-Builder] Re: How to set up a basic crossband repeater system in Pub...
Yes, all of the licensing is in place for both sides (spent last year doing that). The VHF side is the old city Police frequency and we are not doing anything they weren't doing except for the cross-band to UHF. We won't repeat VHF so I think we are okay. Locations and ERP are all correct.

Central Standard Time, [EMAIL PROTECTED] writes: My local Community Emergency Response Team (CERT) has recently obtained a UHF repeater (ICOM CY-F221S). It has two ICOM F221S radios linked together in a nice rack mount box. It has also been set up with a remote mic and speaker off of the outputs on the chassis back panel. The CERT group is licensed for the UHF repeater frequencies and they are in the public service band. They also have a simplex VHF frequency in the PS band (old police frequency) licensed. They have a number of Motorola HT radios (CP200) that operate on the simplex VHF frequency. They are looking at obtaining additional UHF HT radios in the future but would like to be able to use the equipment they have if they can get it to work together. I am familiar enough with electronics to be able to follow directions, but not enough to design anything beyond a basic switch box. I am a network engineer professionally so I am pretty well versed in those areas, and understand logic control pretty well. I am a technician class ham, but don't know a lot about RF as I have not had that much experience in it. I would like to accomplish the following and would love to receive some guidance from someone who has the knowledge to instruct me: I would like to set up a cross band link for them from the UHF repeater, to a VHF radio: This would allow someone on the UHF side to transmit to the repeater, and also cross-band repeat to the VHF side. The VHF side would be able to transmit on the VHF simplex frequency to the cross band side, and it would repeat onto the UHF side. I realize that this would NOT provide VHF to VHF repeating, and that is okay. I want to provide a way that the cross band link can be enabled and disabled by remote DTMF tones so that the bands can be separated when desired. I already have an old Motorola Spectra police radio operating on the VHF side at the site, and it has a dedicated antenna. It puts out 110W which is way too much for what we need. I was thinking about getting an ICOM F121S radio, Astron power supply, and ICS basic controller board. Using the existing VHF antenna, I would hook up the new ICOM (50 watts or less). Now I just need to tie the ICOM repeater, controller, and new radio together into a cross band system of sorts. Am I on the right track? I need some general guidance that can tell me, try this, this, and this. Here is what equipment you could use, and here is how you could tie it together. I have the schematics for the repeater available to me. If I don't want to spend the money for a new ICOM F121S radio, then what else could I connect easily that I can program and would be able to get at a reasonable price. This is all being done as volunteer service so inexpensive is best, but I want to avoid cheap equipment.

[Repeater-Builder] Re: How to set up a basic crossband repeater system in Public Service
To be honest, I'm not sure at this point what I really KNOW :). What I am trying to do seems so simple in a logical way to me, but knowing what inputs and outputs to use for what is all new to me when it comes to RF. I do have folks around with service monitors, and somew knowhow, but I am trying to get a parts list together so I can purchase the required pieces while the $$$ is available to me (another story there - I told them I thought this could be done for under $500 so they said do it). Anyways, the back of the repoeater has a DB25 jack with the following I/O availabe: 6 Vcc TX +15V DC Supply for External Controller, TX Unit Maximum 1 A 7 GND TX DC Ground, TX Unit 8 Busy TX Output Terminal for Busy Signal, TX Unit 9 AFO TX Audio Output, TX Unit 10 DISC TX Discriminator Output, TX Unit 11 TXA TX Transmit Audio, TX Unit 12 PTT TX External PTT, TX Unit 13 TXD TX Transmit Data Input, TX Unit 18 Vcc RX +15V DC Supply for External Controller, RX Unit 19 GND RX DC Ground, RX Unit 20 Busy RX Output Terminal for Busy Signal, RX Unit 21 AFO RX Audio Output, RX Unit 22 DISC RX Discriminator Output, RX Unit 23 TXA RX Transmit Audio, RX Unit 24 PTT RX External PTT, RX Unit 25 TXD RX Transmit Data Input, RX Unit I also know that I can get a OPC-617 cable for the Icom VHF radio that brings the I/O outside the chassis. Maybe I am not explaining the DTMF portion correctly, but I just want to be able to bring the crossband repeat function up and down remotely using a tone code. This is exactly what I need though as I am not sure what all of these I/Os will do for, or against me, and I know better than just to try to connect wires together.

COS is carrier operated relay TOR is tone operated relay. Preferably you'll use TOR as the active low output to key the vhf ptt. There's software settings to make these I/O's as you need them. It is necessary to adjust audio levels into out of each radio. This can be done with series resistors or attenuator pads. Chances are you'll need to use caps to equalize the audio as well. Ideally you'll have a service monitor available to check all this. In lieu of the SM, you can carefully compare between the uhf vhf sides for best match of tone quality levels. Wish I had the tech info near me but it's all at work. You might find a way to use the dtmf decoders in each unit along with some type of latching relay to perform your control functions. I'm pretty sure there's I/O for the dtmf decoder available on the accessory jack. --- In Repeater-Builder@yahoogroups.com, bkcarter33 bcarter2@ wrote: My local Community Emergency Response Team (CERT) has recently obtained a UHF repeater (ICOM CY-F221S). .snipped...

[Repeater-Builder] Re: How to set up a basic crossband repeater system in Pub...
Mike, I appreciate your response and concerns. I should have mentioned in my original post that I am either the the representative of the license holder (Kaysville City) for these frequencies, or in contact with the person who is. I have not thus far used any equipment on the public service band that is not typed for that band, at least as far as I know. Nor do I intend to. We hired APCO last year to get everything squared away on the licensing for the repeater and that was a chore and a half. I don't want to do anything to put that in jeapordy. However, if I have all the permissions lined up, which I think I do; have all the licenses in place, which I think I do also, I need to find the best way to accomplish the task. One problem with working with volunteer organizations such as CERT is that everything has to be done, well, volunteer. We were able to get a grant for some money to get the repeater, and pay APCO to do the licensing, but that source has dried up. We have equipment, and people willing to do the work, but need to keep the professional costs to a minimum, without creating any problems for the local authorities. If I had $$ to spend, where would be the best place to spend it? My thoughts right now would be to have someone with a Service Monitor check our work after we are ready to plug everything in. I can connect wires, solder, and program without any issues. Even using the proper shielding, etc. if I know what needs to be connected where, and why. I agree that this may not be the norm for a lot of people, but we have done a LOT of work to keep this all within the proper authorizations and permissions.
