It would not have been type accepted for that use, the last I checked FM mode was not ‘viable’ on 11 meters up here, and any machine would undoubtedly have more than the legal limit of 4 watts output as well. Of course where there’s a will there’s a way. I would not presume to know the rules ‘down under’ but I hope the idea does not catch on up here. Once the 10 mtr band opens up regularly ( if and when ) it will be a zoo of open access FM repeaters with many of them transmitting at the same time making the band impossible for anyone other than on simplex freqs.

[Repeater-Builder] Portable MSR2000?
I have a VHF MSR2000 in cabinet here at the house that was just removed from a site where it was connected to regular A/C power. An upcoming weekend in April has 4 major events occurring simultaneously which ties up both our fixed repeaters (2 of the events are within coverage of existing repeaters) and our portable repeater (GE Mastr2 with Sinclair Q2220 duplexer). This leaves us with a gap in coverage for the fourth event. Is it reasonably possible to power this MSR2000 repeater station with 1) 12V DC power and 2) bypass the p/a to reduce TX power and current draw? RMD states we can use 10 watts or less for the repeater to achieve coverage to both sides of the site (RMD rules out simplex, even with 50w mobiles and fixed 7 dB yagis). The site we've placed the portable repeater at in the past is several hundred feet off the main road, making powering difficult. The station is configured currently for 65 watt output; this is overkill for the particular site. Any guess on approx current draw for MSR2000 in standby (single rx), bypassed transmit (exciter only) and regular transmit (exciter/PA combined)? Any help/suggestions are appreciated :)

Re: CB Radio Band Repeaters and Remote Base Operation I have heard numerous urban legends of 27 MHz CB repeaters being built. Has anyone ever come across such a thing? They are not legend, there are or have been many examples of CB Repeaters and/or Remote Base Operation out here in California. If not does anyone think it is even possible from a technical standpoint? It's quite possible, quite doable and done more often than you might imagine. the limitations are AM mode, and using any of the 40 CB channels with 4 watts PEP AM or 12 Watts PEP SSB ie: using completely unmodified type certified CB gear. Why..? Depending on your motives for wanting a CB Repeater or Remote Base... the equipment and power level are just minor issues. Legally a repeater is illegal on CB, Class D, AM mode CB Radio voice audio repeaters in the USA are not normally licensed. There are other legal examples out there if you want to spend a lot of time looking around. but i just want to do an exercise in thought as to what problems someone may run into with such a project, etc. Location, vandals, wanna be FCC police types, angry hams, angry CB'ers, bad equipment, interference, crappy equipment, shotguns, hand-guns, broken antennas, bad swr (antennas), pulled down antennas, crappy power supplies.

The rumors are true... no one though has actually went deep into the technical aspects of such a project or could point me out to the people who are operating or operated such a setup. Most of the people operating CB Repeaters and Remote Base setups don't want the extra attention, but their mouths, operating practices and other nefarious activities get them in trouble anyway. There are and have been so many examples here in Northern California... Thanks, Rev. Robert P. Chrysafis cheers, s.
Re: [Repeater-Builder] Just a Crazy Thought

[Repeater-Builder] Quantar RLC-MOT issues. Help!
The local club decided to drop the coin on a new repeater, so they bought a used Quantar station. I'm working on interfacing an RLC-MOT to it. I have the wildcard tables set up properly to allow what I would assume is discriminator audio to be present on connector 14, pin 22 RX Wideband Audio. It's unsquelched, raw audio that sounds like discriminator to me. I'm encountering the following issue: The RLC-MOT works properly. It hears the discriminator and generates squelched audio and COR as it's supposed to. HOWEVER Whenever a DTMF digit is pressed, the RLC-MOT behaves as if there is no carrier present. COR is lost, and the controller won't accept the DTMF since there is no COR present. Why is this happening? I've tried adjusting audio levels on the RLC-MOT, playing with resistors to drop the discriminator audio level, etc. No dice. Any help greatly appreciated. These guys want to get the new repeater on the air soon. Thanks, Chris
Re: [Repeater-Builder] Quantar RLC-MOT issues. Help!
lose the RLC-MOT and program in an output based on receiver activity! That would be easiest. Other than that, is there a SAM board in the station? The Quantar does not really have discriminator audio available as it is a digitally processed platform and it just re-creates it for you. The station could be muting the DTMF tones and that would possibly be why the RLC-MOT board sees nothing? I have never tried that myself, so without being there to troubleshoot the system ... I am just throwing darts at it.

Not really, you woke some of the sleepy ones up... any way. you solved the mystery for me and i have passed it along to the CB forums i am in. which one? some rich little trust fund brat with more money then he knows what to do with will probably read it and wind up building one. Nope, it's more like the whack job drug/booze head without a regular day job looking for another way to drive the locals off a channel. Duct tape, mobile antennas, cheap mobile radios and car batteries are usually involved. On occasion private property and pit bull dogs are part of the physical location.

[Repeater-Builder] Collinear mount tube pressure
Hi guys .I would like to know if other installers have run into the following problem .Installing a collinear base antenna to mounting tube and have turned the u bolts up too tight that the antenna either doesn't work or cracking occurs in repeater . One site I did, I installed a brand new uhf collinear and it had no range and after inspecting it found nothing that I could see wrong .After reinstalling it with a little less pressure on the clamps its working ok with no worries. The second one I have done works but crackles and I hope to check it today I just wondered if anyone else has had this issue when installing repeater antennas and worked out a suitable tension pressure that the u bolts can be tighten too that doesn't cause any problems .

Astron makes a line of DC-to-DC converters, including several that convert 24 to 12 VDC. I'd strongly suggest using at least two converters, rather than trying to run your entire system on one unit. You probably should employ converters that have full isolation, just to be certain that you don't create a ground loop.

Re: [Repeater-Builder] Quantar RLC-MOT issues. Help!
What is the firmware in the Quantar? I have found by using the wireline outputs (assuming it has a wireline option/board in it), setting it for 4 wire wireline for audio in and outs, and setting up the wild card inputs and outputs like are in the back of the manual for an external controller works very well if the repeater has version 14 or higher firmware. Not sure about 13 but 12 and lower the input audio does not work correctly. I have JPS NXU's hooked to over 50 Qunatars in Texas that I can pull up remotly on my company network and they sound and work like I am standing next to it. I am working on mating an RLC-3 to one now.

I'm working on interfacing an RLC-MOT to it. I have the wildcard tables set up properly to allow what I would assume is discriminator audio to be present on connector 14, pin 22 RX Wideband Audio. It's unsquelched, raw audio that sounds like discriminator to me. I'm encountering the following issue: The RLC-MOT works properly. It hears the discriminator and generates squelched audio and COR as it's supposed to. HOWEVER Whenever a DTMF digit is pressed, the RLC-MOT behaves as if there is no carrier present. COR is lost, and the controller won't accept the DTMF since there is no COR present. Why is this happening? I've tried adjusting audio levels on the RLC-MOT, playing with resistors to drop the discriminator audio level, etc. No dice. Any help greatly appreciated. These guys want to get the new repeater on the air soon. Thanks, Chris Yahoo! Groups Links
RE: [Repeater-Builder] 24vdc to 12 vdc converters
Ray, I agree that Samlex makes some very high-quality equipment, but the specific converter you cited is clearly non-isolated. Since most CO and cellular equipment is designed to operate with a positive ground, some serious fireworks will occur if a negative-ground radio is powered from -24 or -48 VDC through a non-isolated converter. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of K6PNG Sent: Friday, February 12, 2010 5:48 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] 24vdc to 12 vdc converters This should fix you up. 73 Ray K6PNG http://www.samlexamerica.com/products/productdescription.asp?ProductsID=6004 2 http://www.samlexamerica.com/products/productdescription.asp?ProductsID=600 42 James Adkins wrote: We have a site that we'd like to run our repeater off the cell phone company's 24vdc power plant, and need a continuous duty inverter to transfer 24vdc to 12vdc.

[Repeater-Builder] Re: Portable MSR2000?
Re: Portable MSR2000 Is it reasonably possible to power this MSR2000 repeater station with 1) 12V DC power Yes 2) bypass the p/a to reduce TX power and current draw? Yes, but the exciter output only is not very much. The hardware is very heavy so it's not a super easy repeater to be moving around as a portable unit. RMD states we can use 10 watts or less for the repeater to achieve coverage to both sides of the site (RMD rules out simplex, even with 50w mobiles and fixed 7 dB yagis). Using just the exciter, you will have far less than the 10 watt maximum. The site we've placed the portable repeater at in the past is several hundred feet off the main road, making powering difficult. No one has a portable gas (or propane gas) generator you can borrow for the event? The station is configured currently for 65 watt output; this is overkill for the particular site. Depends on who you're asking... 65 watts is a nice amount of power to have and use. Any guess on approx current draw for MSR2000 in standby (single rx), bypassed transmit (exciter only) and regular transmit (exciter/PA combined)? AC energy quite a bit regardless of what equipment combination your end up with. The resonant transformer in the power supply is a pretty bad space heater (bullet proof but very energy wasteful) DC operation is more reasonable depending how you connect an external supply in. An MSR-2000 is happy with about 13.8 volts and a separate 9.6 volt supply via an internal regulator circuit. If you rely on the MSR's internal shunt regulators you can consider it an energy hog. The PA will take quite a few Amps to run depending on how many watts it is set up to output. Unless you have the lower power Canadian PA I would question the practical side of being able to turn a standard 110 watt unit down to 10 watts without some PA internal stage bypass surgery. Running on the exciter only is not very powerful... less than 2 watts. Any help/suggestions are appreciated :) First: Figure out a game plan based on the practical use or removal of the RF Amplifier. Will the exciter only power be enough? Second: Is anyone in your group willing to construct a simple 9.6 volt regulator circuit from one of the many available kits or even buy one prebuilt off Ebay. Then using the manual information, connect an external DC Source input for the 13.8 volt supply and the 9.6vdc regulator input and output connections to the back plane board? Will there be milk or cream available for the coffee? cheers, s.
