Hi Eric, I know you have been helping every one on this group, can you please help a unexperience person like me solve one problem on a crank up down tower here in Miami due to hurricane the tower have to goes down,What is the best choice of coax cable to use, because when the tower is down the coax length is loose so have to coil it and tie down to the tower, My question is what number of Heliax that is capable to roll it at a diameter of about 12, your recommendation is highly appreciated.

RG-8 will have about 2.2 dB loss in 50 feet, and LMR400 will have about 1.4 dB loss, at 458 MHz. A far better choice would be Andrew LDF4.5 Heliax with 0.5 dB loss, or LDF5 with 0.4 dB loss. Lose the RG-58 jumpers, and replace them with good, double-shielded cable such as RG-400 or RG-214. These jumpers should be fabricated with the proper high-quality connectors on each end (no barrels or adapters), and should be no longer than necessary.

I've already ordered 50 Ft. of LMR-400 to replace the cheap RG-8. Yet, I wonder if there is something else I could do. The Duplexer is pre tuned to my freq. (458.0 repeater RX / 453.0 repeater TX). The duplexer is connected to the radios (my repeater is built out of two Motorola M120's) using RG-58 jumpers of about 24 inches long. Could that be affecting performance? When I check the TX power thru the duplexer I'm getting about 10W yet the TX radio is programmed for 30W. I know that I'll lose some power with the duplexer, but seems to me that I'm losing too much. SWR won't go below 2.1 no matter how much I adjust the antenna bays. So, what could be done? I imagine that swapping the RG-8 for the LMR-400 will help but I still wonder if that would be enough. Any help will be greatly appreciated. Aisen

Any body know what is the name of relay that have a gear on the side, every time the relay energize once it turn the gear and lock the relay position from normally close to open and open to close, I have one of the relay that work that way long time ago, maybe its still available today. 73 Camilo - Original Message - From: Al Wolfe To: Repeater-Builder@yahoogroups.com Sent: Wednesday, October 22, 2008 10:25 AM Subject: [Repeater-Builder] Re: Shutting Down Battery Back up Scott, You are of course correct about hooking the PA directly to the battery, there being no reason to disconnect it. There are undoubtedly many good reasons to consider a more sophisticated disconnect method than the simple relay circuit described when the ulimate in power saving is needed. However, I wonder what percentage of the folks on this list have the technical acumen to design a circuit like this, let alone trying to gather all the parts for it. The cutout circuit of the solar charge controller you mention does look interesting and the kit for $55 might easily be adaptable to be used in a repeater disconnect application. However, I still feel that the extremely simple relay circuit I described will do the job as it has for me in several applications for many years. With only three or four parts there is very little to fail. When the box it up on the hill I don't want to have to run up there every time there is a nearby lightning strike. The 100 ma. figure is typical of some of the Rat Shack relays. There are many that pull much less current available. Al, K9SI Re: Shutting Down Battery Back up Posted by: Scott Zimmerman [EMAIL PROTECTED] scottn3xcc Date: Tue Oct 21, 2008 8:34 am ((PDT)) If you are concerned about your batteries lasting as long as possible when running on backup, I would NOT use a relay. Even at 100ma of current draw, that's a LOT of current in a backup / solar situation. Since the RF PA only draws current when in transmit, (Class 'C') you can hook it directly to the battery all the time when line voltage is not present. This can be done easily with normally closed contacts on a relay that is fed from the AC line. Have a look at the cutout circuitry of this solar charge controller: http://www.solorb.com/elect/solarcirc/spc3/ They use a voltage comparator to do the switching. I would think a circuit could be designed that simply used a 10V zener diode and a transistor to feed the power FET. Probably until you would go through all of that, you could have the comparator circuit built and ready to go. The moral of the story is that a comparator and power FET switch would draw FAR less current than using a relay coil. You could also set the comparator EXACTLY where you want the circuit to turn off. Be sure that the hysteresis resistor is a small enough value so that when the circuit cuts out with the transmitter active, it won't turn back on when the battery voltage recovers. Of course, this could be tailored to taste.

The battery goes to one side of the N. O. contact and the load (repeater?), power supply, and relay coil to the other N. O. contact. The other side of the coil goes to ground via a resistor. The resistor value is determined empirically and should be selected so that the relay will drop out at about ten volts or whatever you decide is the minimum useful voltage. Use a variable DC supply to determine the proper resistance value. You should be able to find a 12 volt relay that needs less than 100 ma. through the coil. An appropriate resistance might be 22 or 27 ohms for this relay. A 1000 MFD cap should be in parallel with the resistor so that when power is restored from the power supply, full voltage is applied to the relay coil for a time to energize it. The resistor also lowers the power used by the relay to a degree. The ubiquitous chatter diode across the relay coil is a good idea as well. I have used this method for several applications at work and it is virtually fool proof. Good luck, Al, K9SI Now the question and I have not seen this talked about I would assume all I would need is a Normally closed Relay and as the Voltage dropped below a Certain Level it would open and just break the connection to the Battery back up , Is this the way to

Re: [Repeater-Builder] MTR2000 UHF Service manual
Hi Milt its nice for your advice,Yes I have work on surface mount way back maybe 17 years ago at Motorola depot in plantation Florida, and MTR2000 is totally new to me and I like to learn something about this unit, I like to remain active so my old brain won't get frosted, and its boring when you retired doing nothing, Just got this unit off Ebay, it comes with power cord, two fan blower on the PA and power supply side, got the programming software RVN4148M MTR2000 Station RSS R03.02.06 Win, and also ordered the programming cable, now I am a novice trying to learn from you guys like Eric, I just ordered the Depot manual from Motorola the price was up $217.00 and I just buy a 11 X 17 Scanner, in case Eric wanted a copy of the manual. and thanks to all that reply. 73 W4CSO Camilo - Original Message - From: Milt To: Repeater-Builder@yahoogroups.com Sent: Tuesday, October 21, 2008 8:00 AM Subject: Re: [Repeater-Builder] MTR2000 UHF Service manual For the benefit of everyone on the list let me advise all of you concerning the new world of Motorola service; at least when compared to the old days when the MSF5000 was considered the top of the line and the days of antiquity when the Micor was king. I will not even try to find adjectives to describe the days of the Motrac as the king of the hill as most Motorolans today have no idea what a Motrac was. ***Disclaimer*** What follows is personal opinion and in no way reflects the views of the list owners or others on the list. It is also not a timeline. When Motorola created the MSF5000 they crossed over from the conventional crystal based designs of many years to a new world of microprocessor based design. The letters MSF stood for Maximum Station Flexability and the MSF was a very capable station. By using software or the R1800 programmer the parameters could be changed easily in the field, repeatedly. It covered wide swaths of RF spectrum in a single radio. Along with the other microprocessor based radios that Motorola was developing it completely changed the direction that most radio shops were going. The new world of radios created a servicing nightmare. The guy on the bench who had been dealing with crystal based designs and leaded componets all his life now had to decide to either update his skills or maybe look elsewhere. A lot of turnover started to take place in the service environment. And then there was that part about being on a mountaintop with a non functioning radio; how did you drag all the items needed to troubleshoot and repair a PLL circuit based radio with you? Or did you drag the station back to the shop? Motorola made a decision that the generation of station equipment that followed the MSF5000 would be based on the concept of Field Replacable Units. Basically break the radio down into building blocks that can easily be swapped out wherever theradio is located with a minimum amount of effort and equipment. Thus the Quantar radio was designed to be a series of modules in a backplane. Initially no service information was released beyond simple, basic in/out diagrams. A similar philosophy holds true with the MTR2000 radio and will, I am sure, continue into the future. One reason is the complexity of the circuitry and the extensive use of leadless componets and new generation chips which combine a multitude of functions in a single device. Another is the need for specialized test and rework equipment in order to even attempt to troubleshoot or repair the circuit boards. As Eric pointed out, you can procure a Depot level manual from Motorola which will have all the required information and schematics. If you are equipped to deal with high density surface mount rework, then go for it. Otherwise there is the depot.

No setting in RSS for the hang-up box. I wonder why they did away with that. I also discovered that my radio has a serious receive audio problem at the moment; very weak, very distorted. Almost sounds off-frequency or like a cap has gone leaky and has upset the bias in the RX audio chain. If it's not one thing, it's another. Adding a short piece of wire across the two pins in the MIC jack is very easy. You only need a T15 driver to remove the front panel, then a T10 driver to remove one screw that holds the VOL/MIC board into the front. Unplug one connector and you can work on the assembly on the bench.

I've used the plug jumper but in the case of this radio being used as a repeater receiver it would have been nicer to simply toggle the hook-switch in software versus one more hardware mod.

The Off-Hook option appears in the Radio Wide Settings Table as you suggested, but only for the low UHF and VHF band radios. When I use the same software to read a Conventional 900 Radio the Off-Hook option goes away and all I see is the Handset Y/N option left behind. I know the Conventional Firmware for the 900 Maxtrac radio is different from the lower frequency bands... but the off-hook option would normally be expected to be available in both bands. I guess I'm going to make up more Radius Repeater monitor mute plugs. Thanks for taking the time to reply cheers, skipp Bob M. msf5kguru@ wrote: Yes. Check the Radio-Wide settings page, left column, bottom. There should be something regarding the hang-up box (HUB). TAB to that field, press F1, read the HELP screen about it, and make the appropriate choice. Most people just short out pins 3+4 on the back of the MIC jack inside the control head. You can still unsquelch the radio by using the MON button on the front. Bob M.

HAHAHAHA I only wish people would look around more - I don't know HOW many times I almost harpooned someone with that tube before I got it off property. I saw one set of 2m duplexers being practically given away - the guy was pressing me to buy them on Friday (a 6-jug set) for $75. Shame I didn't need a 2m duplexer!! One vendor inside was selling a MTX1000 (I think?) mobile on 900.. Wanted $450, with NO accessories. I asked whether the mic on the rig was included; I was told no, it was a demo. When I asked what I was supposed to do for a mic, the answer was eBay. I walked away. It was still sitting there on his table Saturday afternoon, so I assume he brought it home. That's OK - I really wanted an MCS2000 II or III, anyway... The MSF's there were a tad high for my liking. (So I'm a cheapskate - I admit it! Hehehe) I was trying to find a UHF machine for a friend to use on GMRS - saw a 40W MSF station but the guy wanted $500 and wouldn't come down. Maybe he made a deal later on, but by then I had spent some of my budget on other items... Was thinking of grabbing up one of the Mastr-II machines I saw, but they were on 411 and I was pretty certain they wouldn't move up far enough for use on GMRS. Same guy had a lot of Taits, but again, I wasn't sure whether they move up far enough for my needs... nor am I familiar enough with them to know what model I'd need. All in all, I had a great time. This was my first time, but definitely won't be my last! Next year, we need to coordinate a dinner meeting or something - if only a specific day/time in front of the BRAT vendor. ;-p Mark - N9WYS

Thanks milo - Original Message - From: skipp025 To: Repeater-Builder@yahoogroups.com Sent: Friday, July 13, 2007 3:23 PM Subject: [Repeater-Builder] Micor vhf to 224 MHz conversions Hi Ron, I've tried and completed a number of micor pa mods... it's been a number of years since I did the vhf to 220 conversion. It did work but pretty poor related to what I was expecting or hoping for. Pre modification I measured all stage values levels. Yes I removed the LPF and built a 224 MHz replacement filter using metal caps and coils in a standard 5 section layout. The conversion up was tried in two forms... a reduction in both L and C values were tried with the L values showing the best practcial performance (pretty much required to make it work), which was still nothing to get excited about when the best we could get was less than 40% of normal rated power. We bailed on more conversions because of the ease of hybrid low drive 224 MHz PA Modules and I started just making 224 two and three stage repeater amplifiers with rated 40 watt output. In a file somewhere I have all the conversion noted recorded... our results did vary quite a bit... cheers, skipp Ron Wright [EMAIL PROTECTED] wrote: skipp025, On the Micor PA for 220 I assume you disconnected the LPF and was using a VHF PA. Since the Micor PA did have tuning did you modify the variable caps; lowering their value??? 73, ron, n9ee/r From: skipp025 [EMAIL PROTECTED] Date: 2007/07/13 Fri PM 12:36:06 CDT To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Hamtronics I have converted Micors and it's not even close to a free lunch. Best I was able to do with a full on 220 micor pa conversion was about 20 to 30% of rated power. I also suspect the transistor/devices don't perform very well that far above their spec'd range of operation. s. Ron Wright mccrpt@ wrote: Eric and all, On the PA problem has anyone on the board tried using PAs from say Micors or GE Mastr line made for 150 or UHF on 220. These often have LPF on their output which can be taken out (don't like to). Since these amps are wide band they just might move up/down to 220. Some do have tuning like in the Micor so would be little harder, but GEs only have a pot for adjusting drive/output and some with SWR shutdown circuit adjustments. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
Re: [Repeater-Builder] Re: Hamtronics (and VHF Engineering) Manuals
Hi Skipp is it possible to get a copy from you. Thanks 73 W4CSO - Original Message - From: skipp025 To: Repeater-Builder@yahoogroups.com Sent: Thursday, May 17, 2007 12:32 PM Subject: [Repeater-Builder] Re: Hamtronics (and VHF Engineering) Manuals A big thank you to Dexter for making his COR-2 scans available to Chris I. Many of the vintage Hantronics Manuals are not available on their website... nor does there seem to be a rush to find and post a lot of the early equipment paperwork. For some reason Hamtronics (Jerry) reports he/they don't have manual archives for a lot of older kit and pre-built units. If you're looking for vintage hamtronics information... the group here is a great place to start posting requests. If I don't have it I'm sure at least one of the other members might. As time allows we're glad to help with the information. I even have some of the VHF Engineering (rip) Manuals around... (some of you stop laughing so hard). cheers, skipp skipp025 at yahoo.com Dexter McIntyre W4DEX [EMAIL PROTECTED] wrote: I'm fairly sure I have a copy.

Hamtronics no longer has the manual, and I haven't found it online. The COR-2 manual might be somewhat helpful, although I'm not sure if it was designed more like the original COR (555 timers + audio amp) or the COR-3 (op-amp based). Does anyone have this manual, or at least a schematic? If so, I'd be happy to pay for a copy.
Re: [Repeater-Builder] Re: Uniden 220 repeater, Software info needed
Hi Skipp I think you'll be interested if you know that all the unit are new and still on original box. (MRS204EX-220 MHZ narrow band repeater) they have 24 unit for $50.00 each (ARX2125Z-110 watt 220MHZ RF P.A.) they have 12 unit for $125.00 each. you can find them at... http://www.relmwireless.com/sections/closeouts/pages/Systems/220-f.asp Thank you for your info Camilo - Original Message -From: skipp025 To: Repeater-Builder@yahoogroups.com Sent: Tuesday, February 27, 2007 12:17 PM Subject: [Repeater-Builder] Re: Uniden 220 repeater, Software info needed The repeater is pretty much useless unless you have everything to place it in service... and I mean everything. Uniden Land Mobile Radio is pretty much long gone so there's not much available to support any use of this equipment. The amplifier lends itself to conversion to Amateur (Ham) SSB and FM operation. A thread about the amplifier has been posted on the yahoo rfamplifiers group. http://groups.yahoo.com/group/rfamplifiers/ You can also look up the amplifier and its conversion by n2ckh on his web page. Maybe you can find some archive Uniden Software... but for this unit it's going to be an elusive beast. good luck... cheers, skipp Camilo So [EMAIL PROTECTED] wrote: I just purchased a brand new Uniden MRS204EX 220 MHZ narrow band repeater and Uniden ARX2125 125watt RF PA, the repeater is a CPU programmable, and this unit is a Uniden 220 MHZ prototype repeater, that comes with no software info or manual, I hope someone here knows a Uniden repeater software for 2 meter that I can buy to program this unit, or a 2 meter Uniden repeater manual that I can buy for reference to this unit.
