RE: [Repeater-Builder] cp70-422n
Hi again guys. I checked the notches on eachtin and they were on frequencyand the markings were the correct way around.I removed the tee piece and checked the output after the 2nd tinandthe reading was 15watt so I recheck the output with the tee back inplace and still 7-8 watt output .I adjusted the db disks on the tins and also readjusted the pa section to give max output and ended up with 14-15 watt output with -110db signal with no chopping so it must have been a combination of these things.

Some duplexer designs don't necessarily work better with wider splits. The CP70 duplexer is specified for a 600 kHz split, and its loop settings might not be optimum for a 2.5 MHz split. Check with Celwave Tech Support for a definitive answer. Keep in mind that TX power measured into a resistive (dummy) load can be quite different when measured into a reactive (duplexer) load. Depending upon the make and model of your PA, it may be a good idea to experiment with different jumper cable lengths between the PA and the TX input on the duplexer, or install an impedance matching device (Z-matcher) at the PA output. 73, Eric Lemmon WB6FLY From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ian WellsSent: Saturday, May 06, 2006 3:00 AMTo: Repeater-Builder@yahoogroups.comSubject: [Norton AntiSpam] [Repeater-Builder] cp70-422n Hi guys.

Good Afternoon Gentlemen, I am looking to build a hi-fi quality audio repeater to feed audio for remote broadcasts of a non-commercial radio station which has been greatly annoying, as I need a specific IF filter for a motorola receiver a tu-540w and I have been unable to find the filter. In addition, the chief engineer for the station has been completely un- helpful. While I am not an amateur radio operator, I am building this repeater for amateur radio use on the 144-148 mc band and the engineer of the station claims he has an amateur radio license, but i am beginning to have my doubts and the engineer has not been supportive of building a hi-fi audio repeater. how can i confirm if the engineer has a amateur radio license? is there a listing of engineers and what licenses they have? i went through a lot of trouble to find the older tube type equipment to build this hi-fi quality audio repeater and want to make it work to serve the non-commercial fm station. what suppliers carry older motorola radio parts?

Re: [Repeater-Builder] accepting recommendations
A licensed amateur radio operator would know that what you are proposing is illegal. Also, the chief engineer of the radio station should be doing the engineering, not you. Remote broadcast regulations are covered by part 74 of the FCC rules are very clear. A license is required and it is not allowed in the ham bands. If you are serious about doing remote broadcasts you will look at Marti radio equipment, Telos ISDN equipment or Tieline POTS codecs. These are just a few examples. It's also interesting that you are not willing to put your name on your message.

Re: [Repeater-Builder] Re: Uniden ARU251 Repeater
Yeah, 5 kc off will make it sound kinda funky, and I don't have GMRS rules in front of me but may also be out of legal tolerance. If you are sure your counter is accurate (ck against a know to to correct source), then set the trimmer in the TX module, or see if the shop that tuned it up for you will help - pretty minor thing. If you have new crystals, there may also be a drift problem with the crystals, also, the receive may be off as well. ssb On 5/7/06, bama_guy1965 [EMAIL PROTECTED] wrote: well in response I put the wrong frequency it is 462.550 that itshould be output but it is 5kc off at 462.5456 if that makes anydifference I know its driving me nuts and I keyed it off therepeater itself to get a true reading anymore suggestions would be -- Ham Radio Spoken Here.NU5D YAHOO!

Re: [Repeater-Builder] Re: Uniden ARU251 Repeater
Setting the transmit freq on an Aru251 is a process. Once you power it up , it takes about an hour for the crystal oven to really stabilize. After each adjustment , key it a few times and let it set for a few minutes.

RE: [Repeater-Builder] Re: Uniden ARU251 Repeater
Johnny, The transmit crystal in your repeater is supposed to operate at a regulated temperature of about 176 degrees Fahrenheit, or about 80 degrees Celsius. The crystal should be ordered for operation at that temperature. If the radio shop technician disconnected the heater resistor but installed the correct (oven-rated) crystal, it will be *way* off frequency. The heated TX crystal is mandatory, in order to achieve the +/- 2.5 PPM stability specified by Uniden. Note that the receive crystal has a heater that kicks in only when the ambient temperature falls below about 14 degrees F. The TX crystal heater is a 47-ohm 2 watt resistor. Once it is installed and working correctly, wait at least five minutes after turning on the radio before attempting to tune the TX frequency. I'd let it settle for a half-hour or more. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of bama_guy1965 Sent: Sunday, May 07, 2006 2:46 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Uniden ARU251 Repeater ---well I checked the crystal htr and I suspected he d/c the thing and I have no idea where to reinstall it.

Re: [Repeater-Builder] Mastr III HB station
But, if you just have to do it. Contact Zetron for their wiring list to connect their out board multi tone repeater controller. Also you will find the CG decoder gets talked down by HAM talkies, most do not filter audio below 300 hz, and that with excessive deviation will talk down the GE decoder. There is a software flash code that will fix this problem, until you reprogram the repeater, then you will need to flash it again. ssb On 5/7/06, Steve Bosshard (NU5D) [EMAIL PROTECTED] wrote: I would very strongly (almost to caps) recommend you use the built in controller inherent in the M3.

[Repeater-Builder] Re: Uniden ARU251 Repeater
Yes, I've put the Manual for the ARU-251k Repeater up for free download on the www.radiowrench.com/sonic web page. Also the ARH-351 VHF Repeater Manual. If everything is working, you need to install the crystal into the heater module, seat the crystal pins into the exciter board and provide power for at least 3 or 4 hours before you do a frequency setting. If it's a new crystal, I'd give it at least 24 hours warmup as new crystals in heaters tend to settle in a different final place after the first heat cycle. Anyway, you need to let the repeater set for at least 3 to 4 hours before you even think about aligning it on a frequency. I still hold out for the 24 hour span. How timely someone is working on this model repeater. I'm doing one for Sal right now and it's been a bear. I had a problem with low tx drive/output... after much head scratching I found the TX Crystals were cut wrong. The TX xtal is a standard divide by 12 - third overtone type in the 12.5 MHz Range. The xtals we received from Bomar were divide by 9 - third overtone at 18 MHz. Funny thing is they worked sometimes... but then the drive would go away in one of the tx stages. Bomar being first rate is cutting new crystals for free. The only way to check the crystal type is to have an oscillator test circuit with a matching counter. A nice feature built into my Sencore Desktop Counter... If the guy is confused about the duplexer adjustment, jerk the entire package back from him and find help elsewhere. I've put the GE MVP Phelps Dodge Flat Pack duplexer instructions up on the sonic page. The PD_7560.pdf file. Anyway, lots of time... the manual and a lot of questions over here on the group should help get you straightend out. Since I've had my nose in 5 Uniden Repeaters in the last two months I can almost answer questions on the fly... Like any repeater of that type/generation... they can get a bad rap because someone doesn't have all the proper info.

Re: [Repeater-Builder] Mastr III HB station
Kevin; The Mastr III station manuals currently document the process of hooking an external controller to a Mastr III. If it truly is a Mastr III as opposed to a Mastr IIe there is a quite a difference. I would suggest you get a manual for it and it should have the interface in it, it may even be in one of the LBI's here in the repository of GE stuff.. The documentation dates back to Ericsson era Mastr III stations. The Mastr III stations are not known for moving out of band well... if it is a high split it will require some work to get it to 2 meters.. The controller interface is probably the least of your worries I would make sure the RF part is going to cooperate as it is not just a matter of plug and tune The Mastr IIe ( which is a hybrid Mastr II with a Mastr III control shelf is another matter. It is much easier to work with... Doug KD8B At 09:27 PM 5/7/2006, you wrote: Thanks Steve, but that is not an option for us. It does not offer enough functionality in our situation.

Re: [Repeater-Builder] Re: accepting recommendations
I spoke with the Chief Engineer of the radio station where this volunteer helper wants to build this Hi-Fi Ham Band 2-Meter Repeater for a link for the local FM Stereo station. This situation came up some months ago, and should have died by now, but it seems to have appeared again. He tells me that trying to reason with this stubborn guy is just absolutely impossible - he has his mind made up that he's going to do this project, this way, and that the Chief Engineer has no idea what is going on regarding building Repeaters, when he in fact has a very well designed, excellent performing 2-Meter, UHF and 6-Meter Repeater system (with additional internet and RF links, etc.) He knows what's going on when it comes to building Repeaters, and has even done some of these things like changed out some of the lifetime warranty Permakay filters in years past (but going from wideband to narrowband filters - not the other way around!) There are no vacant 2-Meter pairs in this big city area, and even if this was something that was legal to do (it isn't, of course), he'd be on a 20+ year waiting list for a channel to become available. And it certainly would not be a Wideband channel. It certainly takes all kinds - we see it right here on this list, sometimes!

Hi Larry, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: and has even done some of these things like changed out some of the lifetime warranty Permakay filters in years past One of Motorhead's better foot in mouth offers. Lifetime Warranty on Permakays. In the late 80's we still had guys walk in off the streets trying to get the filters replaced free. (but going from wideband to narrowband filters - not the other way around!) Doesn't make much sense, but I have seen it done and I've been involved with a wideband remote or two used at the local flame thrower stations for traffic reports. There are no vacant 2-Meter pairs in this big city area, Regardless of what anyone says or does, there are always repeater pairs available in most any location. Two guys with 10 minutes total daily use don't justify holding down a repeater pair when 35 plus people want to use it the other 23 hours. You just have to find the silly empire repeater operators and figure a way to work something in. Most often things end up in a big war... but well planned co-channel operation can and should happen in crowed conditions. Not to mention the non standard repeater pairs. and even if this was something that was legal to do (it isn't, of course), he'd be on a 20+ year waiting list for a channel to become available.

[Repeater-Builder] Re: Uniden ARU251 Repeater
Johnny [EMAIL PROTECTED] wrote: Setting the transmit freq on an Aru251 is a process. Very true.. a long one at that... at least to do it right. Once you power it up, it takes about an hour for the crystal oven to really stabilize. It's actually just some piggy back parts on the crystal, not a complete oven. I'd give it at least a few hours warm up after a few different long term power on/off cycles. The new crystals will drift quite a bit and settle down after some power cycles have occured and you've let it sit on for a few hours min. After each adjustment , key it a few times and let it set for a few minutes. Operation of the transmitter shouldn't really change the actualy TX Crystal frequency, just the temp of the tx rf power amp heat sink. cheers, skipp Yahoo!

Have one for me while you're there - It looks like I'll have to miss this year :-( But I do keep checking the airfare websites every day just in case - I look at fares to Dayton, Columbus, Cincinnati, Louisville, etc. No reasonable airfares to be found (I've been checking every day since before the beginning of the year).

[Repeater-Builder] Portable Repeaters
I've not been too successful in convincing the various Upstate New York Amateur Radio Associations that simplex repeaters are the answer for providing portable repeaters in critical incident response situations. They are relying on the fixed repeaters to provide adequate coverage but there are areas where it would be advantageous to bring the repeater to the incident instead of trying to reach fixed repeaters with hand-held units from some isolated locations. There are, of course, coordination problems with portable duplex repeaters and there is no apparent interest in agreeing on a wide- split pair of odd frequencies to avoid the conventional-frequency pairs. What experience has there been with the use of portable cross-band repeaters to enable hand-held units using a 440 MHz simplex channel to reach the portable repeater that will relay the message through to a two-meter fixed repeater?
