The PL encoder plugs into the exciter, not the card cage. One jumper cut on the exciter board is required. After he installs such a card, would the repeater transmit the 146.2 PL tone, even if activated by the Tone Remote? Yes.

After posting the orgingal question, there were a number of posts to this thread. For those that are following along with this maybe it would be a good Idea to have a test setup procedure located in the file section that would show us that don't have the experience of checking the transmitter how to do run these checks. As a repeater owner I want my audio to sound good and the information I obtain from this simple question will help me at least run the tests and hopefully fine the fix. Great job by the folks here and the best thing of all is that I learned something. Oh and Tom about those graphs sometime pictures are worth a 1000 words! Mike W1ZFB

Kevin Thanks for the repleis. In referance to the channel element, is there a way to sweep the element by it self, or is that something that ICM or someone like that would have to do? You've hit on something I hadn't thought about. If this could be done by it's self it would be better than having other items in the circuit that would contribute to the problem. Also in support of this idea of the channel causing the problem I've switched exciters but not the channel element. I wouldn't be apposed to having ICM crystal up a new channel element but I want to make it's the problem first and then I'd want to make sure the new element wouldn't have the same problem.

The receiver is stock and the frequency has been changed to the 440mhz band. The audio coming out of the receiver has fine audio quality. Just looking for your thoughts or ideas. Thanks for your input Mike I'd make sure the channel element is not limiting the quality of your audio. Consider doing a sweep of the frequency response at several deviation levels and see what you have. I've seen re-crystaled elements that were less than good. Kevin

You can inject audio from a audio generator directly into the modulation pin of the element - past the audio processing. The spot where the PL is injected is a good place. You can use a scope to insure that the modulation voltage is consistent with frequency. I like to test at several frequencies and at different deviation levels.

I wouldn't be apposed to having ICM crystal up a new channel element but I want to make it's the problem first and then I'd want to make sure the new element wouldn't have the same problem. This isn't usually a problem on UHF because of the whole tripling of the RF. (The vhf exciter only needs to deviate a distortion-less signal to 1/3 your maximum deviation amount on UHF (which is likely 5 kHz)), so you really only need to rubber the VHF output to 1.67 kHz deviation. Since the VHF signal is multiplied 12 times, the crystal itself only needs to deviate about 139 cycles on either side of center frequency to result in 5 kilohertz deviation on UHF. That said, I've seen it not be right. Someone else mentioned the possibility of audio coupling capacitors that have aged and lost capacity; and possibly have become leaky. This will result in off-bias and lack of quality coupling between stages and cards. Kevin Custer

Hi Jim, I understand about the 2012 changeover, and all of our radios are capable. However, if I can put together a backup repeater that will be a viable alternative for less than $100 that will last us until that time, I consider it a good investment.

Thanks, Tim I wouldn't put anything into doing that for a Fire Dept. By the end of 2012, they are REQUIRED to go narrowband on VHF and UHF (low band and 800 are exempt). While there are kits to modify the receivers for Micors and others, there is some serious question as to whether the transmitters can be considered 'certified' or 'accepted' for narrowband use. It's more then just turning down the deviation. There is adjacent channel noise/splatter to consider. Not to mention frequency stability.

The helical resonators for the lower of the two splits (xxx1 and xxx2) covered from 132 - 150.8 MHz. The helical resonators for the upper two splits (xxx3 and xxx4) covered 150.8 to 174 MHz. The better thing to do would be to trade someone looking to do a 220 conversion. The xxx4 is the better receiver to start with when doing a 220 conversion.

Re: [Repeater-Builder] Re: Micor Repeater - ID?
A community repeater is shared by multiple users, each using a different PL/DPL code. If all users have decoding set up and the mic hung up, no one hears anyone else until the user goes off hook. The hardest part of operating a community repeater system is to educate all users that if someone else is talking they can't barge in and overpower the other user. LTR is so much nicer...

RE: [Repeater-Builder] Re: Micor Repeater - ID?
I have two Kenwood Community Repeaters, one on UHF and the other on VHF. The thing that makes them a community repeater is they have a multi user CTCSS or Digital Tone Panel and each user/customer is assigned a tone. The newer mobile units and portables are set up for BUSY CHANNEL LOCK OUT which means that if a user goes to use the repeater when another user is on the air, the mobile unit or the user waiting will get a tone/flashing light to indicate that the channel is busy and it prevents someone from cutting in on an on-going conversation. So it is like any other repeater except it has the multi user tone panel.

RE: [Repeater-Builder] Re: Micor Repeater - ID?
Mike, A community repeater is simply a shared repeater, and the individual subscribers have unique PL or DCS tone pairs assigned to them. For example, Ace Taxi might have PL tone 82.5, Jones Ready-Mix might have 97.4, and Smith Funeral Home might have 131.8. When the radio traffic is very sporadic, none of the users are aware of the other's existence. It works fine until the number of users is increased to the point where collisions occur. Most community repeater operators use a radio feature called Busy Channel Blocking which prevents other users from transmitting on top of a user who is using the channel. Of course, the FCC requires users to first ascertain that the channel is free before making a call, and that is why most commercial radios go into carrier squelch mode when the mike is removed from its hangup clip. Unfortunately, some community repeater users seem to think that their subscription entitles them to immediate and eternal use of the radio channel, and they become annoyed when the radio won't let them transmit. It is for this reason that simple trunked systems with as few as three radio channels have largely replaced community repeaters. However, community repeaters still have a place in the scheme of things, when the users have very infrequent and low-key traffic. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mike Benonis Sent: Monday, February 04, 2008 5:23 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Micor Repeater - ID?

RE: [Repeater-Builder] Re: Micor Repeater (i hope)
A couple of basic things come to mind: 1. Do you have the PL encoder plugged into the exciter? If not, did you install the jumper in the exciter board? 2. Did the station originally have the F1-PL card? It provides one (or more) keying voltages, but I'm not in the office and I don't remember which for sure, but it may be oscillator ground or one of the keyed voltages. The fact that you see PA power start to come up but then it dies shortly thereafter almost makes it sound like it's NOT a control logic problem, but then later you said that you're missing keyed A- so that contradicts that notion. As a test, pull up the PA power control line to A+ through a low-resistance (say, 4.7 ohms), key the station, and then while it's still keyed, disconnect the pull-up. Does it continue to make power, or does it drop out? The power control board will shut down the PA by killing control voltage if it doesn't see power output come up fast enough; I'm wondering if that's what you're experiencing. You could have a bad diode or other problem in the antenna network which results in the power control board thinking there is a PA problem so it shuts it down. Put a voltmeter on the sense voltage lines going to the power control board to verify they're good (you'll have to pull up the control voltage to get the PA to make power to take those measurements). By the way, are you using the stock supply or something else? And which PA (power level) do you have? If you can't get it to fly, drop me a private email and I'll get out the orange book to refresh my memory on the keying logic next time I'm in the office. --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, December 30, 2007 5:53 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Micor Repeater (i hope) Hi All Building a Micor Repeater from Scratch Facts.

Ralph, W7HSG ---BeginMessage--- Eric, There is a list of the min required jumpers used in the MSR-2000 repeater station included in my MSR-2000 to external repeater controller text found at the www.radiowrench.com/sonic web site. Working from a decafe based hazy memory... there should be 4 to 6 jumpers required on the back plane. And the remaining modules need some specific jumpers and mods depending on your choice of carrier squelch or ctcss (pl) operation, which can be set up as selectable. You're looking at placing the repeater into duplex mode, which normally requires specific modules be in place with a number of jumpers. Buy a used Motorola Micor Repeater Squelch Gate off Ebay, swap the end connector with an unused MSR Module and save big $ The big issue module combination wise is the transmit channel element ground/enable, which can be provided by the wire-line and/or squelch gate module. If you pull the F1-PL/Guard Tone Modules in the wireline tone control combo or the DC-Transfer module in the wireline dc current loop combination... you need to install jumpers JU-5 and JU-6 on the new Squelch Gate Module. You can Email me direct if you have more questions... or I'm happy to answer them through the group if they don't drag out to long and torque off the neighbors. Removing the T/R Relay is no big deal so that's not a problem.

Does anyone have any experience in converting a conventional MSR 2000 base station into a repeater? I would also guess that I need to remove the antenna relay, and connect the receiver to the receive side of the duplexer and the transmitter to the transmit side. Of course I would also have to have the channel elements re-crystalled. Is there anything more to it than this? Any advice would be appreciated.

well if the unit can not be used as a repeater or it can that should be a part of repeaters also. we got a number of Micors still in operation (6) , and as long as we have them out there working this would be a good think to know.

When they were removed from the approved equipment list? I know CAP has been removing a lot of equipment that once WAS approved for CAP use. Actually, don't most radios specify that they meet type acceptance as of the date of manufacture? The implies that they may not meet the current TA criteria. Do all the wideband radios (+/-15 kHz deviation) still meet TA for Part 90? They ONCE DID! I'm sure they were marked with a TA number, too. However, that TA is no longer valid for most services.

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted
I think there is some mis-information fueling this discussion which needs to be clarified. The specific designated Micor stations would need to have been de-certified due to technological changes in the GMRS rules which would prevent it from complying. The FCC rules to GMRS were not amended in any form, which I am aware of, which would drop the certification of any station which was previously certified under those existing rules.To become de-certified a technical change, which it ( said equipment) cannot comply with, would need to have occurred, like freq stability, emissions, part 15 radiation etc If technical changes ( which stopped Progs etc) from compliance occur, like tightening emissions standards or such, that is another matter. This appears to be an clerical oversight in changing of the method approvals are recorded. Technical standards changes like these have been occurring in other services, but even deviation limits and narrowbanding do not de-certify radio's in part 90 etc... NTIA is another matter as mandated emissions standard changes affect MARS and CAP due to narrowbanding and such . The approved lists for NTIA services are adjusted as they determine the specific model can or cannot be made compliant with NTIA regulations. (12k5 narrowbanding to be precise) As NTIA has absolute control over those licensees it oversees ( govt services) it can dictate whatever it chooses. Tube equipment like Progline, etc were dropped as they were not compliant with emissions standards as we went to 25k channel standards. Nothing more...

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted
Well, as it HELPS to know if the repeater you are planning to put on the air is technically sound to put on the air, I don't know what would be on topic. Are we to be limited to talking about how to build HAM repeaters only? (which don't need TA) That said, who are you to decide what is off topic. Not every topic can be of interest to everyone. If that were the case, nobody would be able to discuss anything. Now if Kevin were to make such a post restricting list use, that would be different, but I don't see you signing your post as a moderator (or signing it as ANYTHING, for that matter). I would hope Kevin would let the discussion continue, as it is of VITAL importance to anyone putting a non-ham repeater on the air. Personally, if a topic is not of interest to me, I use the delete button rather than gripe about it - especially on the list. If you don't want to see an entire thread, add it to your email client's auto-delete using the subject as the filter. *Poof*! It's gone! Joe M.

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted
Well Joe M, lets see here The originator of the coordination topic already asked everyone concerned about the coordination issue to take it to a private forum or email list and not to burden the rest of the repeater builders with a local matter. Did anyone read it and follow Matthew's request...You apparently didn't. I think notSPAM bs to follow the list server... As for type acceptance, who cares...This forum isn't the place for people to interpret fcc crap, take it offline to an ffc forum. The forum I think was intended to support folks to build repeaters not interpret rules regulations of the FCC. If everyone were to interpret the FCC rules we would have more opinions than @ssholes giving advice. If anyone building a repeater has concerns with any equiptment they plan to use as a repeater this really falls on them to validate said equipment with the FCC as they are the actual responsible party to the FCC. The arm chair legal folks need to park their advice for what it's worth...NOTHING. My 4 cents worth... --- mch [EMAIL PROTECTED] wrote: Well, as it HELPS to know if the repeater you are planning to put on the air is technically sound to put on the air, I don't know what would be on topic.

Every station in a GMRS system must use transmitters the FCC has certificated for use in the GMRS. Write to any FCC Field Office to find out if a particular transmitter has been certificated for the GMRS. All station equipment in a GMRS system must comply with the technical rules in part 95. Notice they say to WRITE. NEVERcall the FCC and get a rule interpretation by phone, It is legally worthless. P.S. dont worry, be happy, run your Micor. Chris N9LLO Yahoo!

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted
Were you told they don't know anything about this or that "These older radio's are NOT FCC type certified for use today on GMRS under part 95". Your reply is ambiguous and it seems very incorrect since this other gent has it in writing from the FCC that they ARE type accepted. If you have it in writing that this waas an error and incorrect it would help your argument. - Original Message - From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Thursday, March 03, 2005 5:03 PM Subject: Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted We just checked the FCC list and it is not there we call the FCC and they do not know any thing about this.We where told today that it is not true.

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 TypeAccepted
The first radios I ever saw on those frequencies were made by Vocaline (sp?) and the radio service was known as Class 'A' Citizens Band. Long before GMRS came along ... This was in the late fifties I believe.

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted
If your question mark was questioning that name, Motorola is the third generation Galvin company. The second generation company was Galvin Manufacturing. I don't recall what the first was. I know the first company made car heaters. The second company was started after the first failed, and specialized in repairs to the defective equipment made by the first company. The third time really was the charm, it seems. I would have thought you knew that, Neal. Joe M. Neil McKie wrote: My earliest Motorola Manual is dated 4/46.

Re: [Repeater-Builder] Re: Micor Repeater is PART 95 Type Accepted
Not to get into a rules debate... BUT... Just because a radio was once type accepted doesn't mean it STILL is for a particular service. Not saying the Micor falls into this category, but it might. If a radio used to be TA'ed in 1961, it doesn't mean you can still use it today. So, the old TA lists are meaningless unless you happen to have a properly configured DeLorian. ;- Joe M.
