[Repeater-Builder] Re: Sinclair Dual Circulator Help
The Sinclair document on RB states the retuning works over a bandwidth of 2-4 MHz. My guess is that the narrower range is for the lowest frequencies (132 MHz), and the wider for the higher (800 MHz). The shift from 142 to 145 may not be possible. Please keep us informed of the end result! Wes ARRL Technical Specialist AE6ZM VE7ELE Lincoln, CA CM98iv Placer County ARES
RE: [Repeater-Builder] Motorola Quantar T-5365A
Rob, The Model Designation T-5365A is a family number that applies to ALL Quantar stations, whether VHF, UHF, 800 MHz, or 900 MHz. Even if we assume that you're talking about a VHF unit, we need to know what modules and options are in the station to answer your questions. Most VHF commercial Quantar stations are designed to operate in the Range 2 split of 150-174 MHz, and cannot be tuned to operate properly at 2m. It is rare to find a Range 1 Quantar that operates in the 132-154 MHz split. The receiver, exciter, and power amplifier are different between Range 1 and Range 2 stations. Of course, a Range 1 Quantar is extremely valuable to Amateur Radio operators, since it can operate perfectly on 2m. The list of options for a Quantar station is several pages long. It would be a good idea to make an inventory of your station's module numbers and included options to determine its pedigree and capabilities. Although a mint-condition Quantar station is a beautiful sight to behold, it's not worth anything if it can't operate properly (operative word!) on the intended frequency.

Rob, The Range 2 unit covers the 2 meter band just fine. I have one in service with no issues at all. Lives on the same site with a paging, a buch of VHF public safetytransmitter on 152.0075, The price is dependant on power, options and firmware. Take a look at http://www.repeater-builder.com/motorola/quantar-id/quantar-article.html on how to ID a potential unit. Martin

The Quantar has been Motorola's top of the line infrastructure grade base/repeater station since its introduction in 1992. It has been in production for more years than any other Motorola solid state station was - Motrac, Micor, or MSF5000. Obviously, there have been many revisions over the years. For use in analog operations this is less of an issue than for digital applications where various formats have been available. The VHF Quantar comes in two ranges. Range 1 covers 132 to 154 MHz and is ideal for 2 Meter operation. Range 2 covers 150 to 174 MHz. Range 2 units will generally operate on 2 Meter frequencies above 146 MHz but usually won't lock on 144/145 frequencies. In addition, it has been discovered that Range 2 Quantars with Epic-III station control modules have a low transmit audio issue if taken out of band. The only fix identified to date is to replace the station control module with an earlier or later version. There are several versions of modules available for these stations and there ave been many firmware versions. Only certain combinations are compatible so it isn't always practical to simply mix match Quantar parts. Unless you are very familiar with these issues, it is best to acquire a station that is correctly configured / optioned / versioned to work for your intended aplication. Used VHF Quantars have sold between $2K and $4K. Due to commercial demand, UHF models often command somewhat higher prices. Interfacing a Quantar to external devices and controllers can be very easy. The station manual has an applications section that gives specific details. All Quantar frequency and operating parameters are software programmed. The only physical station alignment is the receiver preselector. The manual gives a procedure similar to that for the MSF filters, but if proper test equipment is available, a swept alignment is the quick optimum method.
[Repeater-Builder] Maxtrac Power setting question
When setting the power level on a maxtrac, do you set for the power level at your intended frequency of operation or do you do it at the test frequency that's in the software and live with what you get at your freq? My example- Installing a 40w VHF 146-174 Maxtrac in the car for mobile operation, not repeater duty. If I set the output power into a dummy load at the test frequency in the software (I think it's @159 meg)to 40 watts, I get 19w at 146.000 22w @ 147.000. I don't want to blow up the finals, but it would be nice to eek a little more out of it in the ham band. I would much rather use the maxtrac instead of the 50w Icom Ham rig, its audio is so much better I dont have the eternal alternator whine that the Icom just needs to have to be happy (Thats a different story all together). Thanks! Tom W9SRV
RE: [Repeater-Builder] Maxtrac Power setting question
Tom, The answer is: Neither. The correct method is to use the Calibrate Power screen to adjust the power setting at each of 16 calibration points. When performed per the RSS instructions, the power output will be uniform at any point within the band edges. All of the nuances of the RVN4019 software are explained in the MaxTrac RSS User's Guide 6880900Z03, available from Motorola Parts for about $33. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of tgundo2003 Sent: Sunday, June 14, 2009 11:30 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Maxtrac Power setting question When setting the power level on a maxtrac, do you set for the power level at your intended frequency of operation or do you do it at the test frequency that's in the software and live with what you get at your freq?

[Repeater-Builder] Rebuilt Celwave RFS antenna
I need some help on a Celwave antenna I'm trying to fix. It's specs are 460-470 mhz 6db gain. Do not have a exact model number but I will try to find it. I bought it off ebay with the person stating they had no idea what was wrong with it but once I received it and took the fiberglass housing off, I found the problem. Or atleast I hope. There is a 7 or 8 copper elements I can't remeber exact with plastic spacers inbetween. A center conductor, looks like a center conductor of about the size of RG-213 runs through these elements and on top of the last element the center conducotr bends up through the hole and is soldered on a aluminum clad. The solder had rubbed or at least thats what look liked had happend and the center conductor had been disconected from the antenna. What I need is some information in conduction a ground plane for this antenna. I assume this antenna requires a ground plane because the way I understand a antenna works is the signals radiate down to the ground plane and then scatters horizontally. Can someone give me some help or info on weather a ground plane is neccasry. It will me U bolted on a 40 ft Rohn tower if that helps any.
Re: [Repeater-Builder] Maxtrac Power setting question
Thanks Eric! All these years of programming maxtracs and somehow I missed that one. Did four radios this afternoon, all now happy across the band. What was interesting is two of them are still factory set from motorola they were no where near right either. Thanks again!

[Repeater-Builder] building a repeater out of two MTS2000 hand helds
Just a week ago the provincial policeforce handed over to our DARES unit (Dutch Amateur Radio Emergency Service)their whole old analog radiosystem, consisting of about 630 Motorola MX 2000 and MT(S)2000 handhelds!!! That was realy fun to receive as you can imagine. Now we like to build, for emergency purposes, some portable repeaters out of two MTS 2000 handhelds. Things like duplexfilters and some kind of repeaterlogic is no problem but connecting them together is something else!! On Batlabs I found the pinout diagram of the accessory cable but I can't figure it out how the handhelds are switched from rx to tx. I even disassembled an NMN6191C telemike unit but that is far to complex to understand (at least for me)Can someone help me with this and explain to me how these handhelds are switched via the accessoryconnector or mayby someone has allready build a repeater with it... Your help is much appreciated! 73' Wim, PE1PME

I'd bet it will tune down to at least 445 if it is a midsplit one to begin with. Worst case, you may have to move of the caps on the stripline a bit.

RE: [Repeater-Builder] building a repeater out of two MTS2000 hand helds
Wow! The windfall makes your club the envy of Hams, worldwide. Congratulations on your enormous collection! Before the Repeater-Builder crowd can answer some of your questions, perhaps it would be a good idea to ask a few: 1. What are the complete model numbers of your radios, from the label under the battery? 2. What frequencies will you use for a portable repeater? More to the point, what is the separation between TX and RX (which dictates the type of duplexer you can use)? 3. Do you have the detailed service manuals for this equipment? 4. Do you have the software, RIB, and cables to program these radios? Connecting the PTT to the transmit radio is easy, and you can use a cable from a remote speaker-mike to handle that chore. Finding a signal in a portable radio that follows a valid receive signal is more of a challenge, and really requires having a copy of the detailed service manual. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of pe1pme Sent: Sunday, June 14, 2009 3:13 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] building a repeater out of two MTS2000 hand helds Just a week ago the provincial policeforce handed over to our DARES unit (Dutch Amateur Radio Emergency Service)their whole old analog radiosystem, consisting of about 630 Motorola MX 2000 and MT(S)2000 handhelds!!!
