[Repeater-Builder] Re: Motorola Purc 5000 As A Repeater?
There is a third controller. Advance Controller used in the simulcast models. Completely programmable from the key pad. Has audio delay built in for the simulcast delays. Watt meter and the software can set deviation, audio eq. frequency's. I am simulcasting a 350 watt and 100 watt on 2 meters. http://www.n6icw.org/equip1.htm I use the rf shelf with a 902 Rx that come from the control hub of the system. The Advance Controller has a 4 character display. 16 button key pad for programing. PTT and Tx audio input using DB-25 socket on the side of the cabinet. Audio can be heard live direct off the controller at: http://72.245.148.218:8022/listen.pls Chris N6ICW
Re: [Repeater-Builder] DB4062 woes...
Hi John, If you can get in touch with him I would interested to know more about what he did, especially if he cleaned the silver plated part (the plunger). Mine isn't all that dirty but I would like to clean them if I can do it safely. Also if he replaced the compound that the plunger is coated with, I would like to know what he used. I'm not sure what the stuff is, or why it is there - scratch prevention/lubrication, as and aid to electrical conductivity, anti-oxidation? In some of my cavities the stuff has started to dry out, so it ought to be cleaned off and replaced. Cavities I've worked on in the past didn't use any paste on the moving parts. 73, Paul N1BUG kf0m wrote: Hey Paul, another ham in my area had our DB4062 apart earlier this year for a similar problem lots of rx noise when I wiggled on two of the tuning knobs in the rx chain.

Well I finally got the courage to tear apart my duplexer. The spring and finger stock appear to be in excellent condition with good contact pressure. However... If you look at this picture: http://www.n1bug.com/cavity.jpg You can see the end of the tuning plunger. The tuning rod is soldered to this end plate. Silver solder I'd guess. What you can't see in this picture is that at the top of the plunger there is a similar metal plate... the rod runs through a hole in that plate, but is NOT soldered to it, and there is considerable play. This is where the audible vibration comes from when I lightly tap the tuning knob. My first thought was since this is up inside the center part of the cavity there wouldn't be any RF voltage/current at that spot. BUT... this cavity is extremely sensitive to vibration, producing severe desense with the slightest tap on or near it. I can find NO other sign of anything that might cause it. Could this loose metal to metal contact where the tuning rod enters the top of the plunger cause this problem? If so, why would it not have this problem when new, but develop it after many years? Seems there must have always been a bit of play there... no? I used this successfully for several years, then it became progressively more sensitive to vibration and started having intermittent periods of severe noise desense... but a tap or two here and there on the duplexer will either greatly aggravate it or temporarily cure it. If that could be the problem, the challenge is getting at it to fix it. The plastic knobs apparently have a metal insert and are securely SOLDERED onto the rod, so getting them off without burning them up is not trivial (at least not for me). If I unsolder the rod from the plate at the bottom of the plunger I would be able to pull the plunger part out the bottom, leaving the rod in place... but then there's no way to solder or otherwise secure the rod to the top end of the plunger to fix the problem. The only solution I can think of is to cut the rod just below the knob, and screw the whole thing out the bottom... solder the rod to the plunger top end plate, screw it back into the cavity and put a new knob on it.

[Repeater-Builder] Thanks re DB4062 project
Thanks to all who responded to my request for help/info on this duplexer restoration project. I returned it to service yesterday. I'm now seeing better measured performance than ever before, and I am unable to make it go noisy by lightly tapping it as I could previously. I have a good feeling about this, but because its problems were somewhat intermittent before I hesitate to say it is fully cured at this point. I see no evidence to suggest it isn't... I just want to see it stay this way for a while before I proclaim success. If there is interest I can post a lengthy report on what was done and the results, or maybe even write up an article about it. 73, Paul N1BUG

If you're the type of person who enjoys doing things from the ground up... then the conversions and kits are the way to go if you have the test equipment to get the show on the road once it's built. Otherwise you might consider a turn-key repeater from the Repeater Builder folks, Hamtronics or Maggiore. I would not suggest you go with the Midland 13-509 conversion because after all the work is done... the receiver is just not the best performer. I just sold a well done Midland 13-509 conversion on Ebay. Item number: 140158007480 if you want to see what one looks like. I have Selection D brands of 220 repeaters in operation. That being 'all the above in brands like Hamtronics, Spectrum, Maggiore, conversions, receiving converters in front of commercial radios and commercial radio conversions. I just sold off the Midland 13-509 conversion so I guess that's off the list. They all work for what they are... The serious Repeater Hawk really wouldn't be happy with a 13-509 conversion unless it's the only game in town. Better to get a receiver made for the application... as in the proper front end and image protection. On a sidebar note... I just replaced a dead Icom 220 repeater receiver with a drop in Hamtronics unit and much to my surprise it's working like a real champ. In fact it's quite a bit more alive than the original Icom receiver it replaced. I'm also very happy with Maggiore Hi-Pro Repeater purchased a few years ago.

One was a UHF and the conversion removed the last doubler from the exciter and the following tuned circuits tweaked to compensate. The dev pot was cranked up to compensate for the missing doubler. The existing 440 receiver was used as a control receiver. The 220 receiver was a converted Micor in a Spectra-Tac chassis. The conversion of the high band transmitter was different - the 75mhz to 150mhz doubler was converted into a tripler and the following tuned circuits tweaked to compensate. The receiver conversion was similar - triple instead of double in the LO chain. I have no idea what he did for a front end. If anybody wants to do a 220 Mitrek conversion article I'll make room for it on the Mitrek page.

Re: [Repeater-Builder] 222 Mhz
I built my first ever repeater in 1979 using a split Midland 13-509. They are really easy to turn into a repeater. The TX puts out a good 10 watts and the receiver cannot be beat as far as sensitivity is concerned. My 220 repeater was on the air over 20 years as the Midland. It never ran more then 12 or so watts to the duplexer and the power at the antenna was maybe 3-4 watts. The antenna was a 6 dB crappie pole side mounted at 250 ft. on a 450 ft. tower.

Re: [Repeater-Builder] 222 Mhz
I've got a 110-watt MASTR-II mobile sitting out in the garage that I've been meaning to convert, but never got around to it... docs, cables, control head, the whole works. 8 channel E-series (thick profile), CG, 6 pairs of ICOMs installed. Even picked up the NHRC-VSQ (internal plug-in volume squelch controls) for it. Wound up using the NHRC-2 controller for a GMRS repeater project instead. It'd be expensive to ship, but make a reasonable offer and it's yours...

RE: [Repeater-Builder] 222 Mhz
Group, I have been working on converting a E F Johnson Fleetcom 530, got the exciter done with .8 of a watt out of the exciter and have most of the receiver tuned but am having problems with mixer. Just no time right now to finish it. After I finish my new workshop I plan on getting back on it, will have a lot more room.

Re: Re: [Repeater-Builder] 222 Mhz
Keith--- If you are looking for a turnkey rig like the Maggorie---be sure to look at the ACS (Advanced Communication Systems) repeater lineup. Very good receivers with helical resonators and they come with a CAT-1000 controller and power supply built in. And, I think ACS will also sell receivers and transmitters seperate.

RE: [Repeater-Builder] MSR2000 info
Ron, The model number does not reveal the specific split. Here's how C73GSB-3145B breaks down: C Compa Station 7 110 watts 3 VHF GSB Fully optionable, with intermittent-duty PA 3 PL tone squelch 1 N/A 4 Supplied with two TX and two RX frequencies 5 DC Remote control B Later model Base Station (not a repeater) The intermittent-duty PA (GSB models) covers the entire 146-174 MHz band. The continuous-duty PA found in the KSB models is offered in three splits: 132-150.8, 150.8-162, and 162-174 MHz. To determine the split of your station, look at the number stamped on the receiver/IF board. If it ends in a 1 as in TRD6291A, it is for the 132-150.8 MHz split. If the number ends in a 2 it is for the 146-174 MHz split. Be aware that there are some significant differences between a base station, which you have, and a repeater station which will have a model number ending in BT. The duplex exciter differs from the simplex exciter, and there are rows of filters to keep RF out of the receiver, along with additional shielding plates, that exist only in repeaters. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ron Wright, Skywarn Coodinator Sent: Tuesday, November 06, 2007 7:04 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] MSR2000 info hi all, Anyone know details of a MSR2000 with part number C73GSB-3145B.

[Repeater-Builder] Micor spectratac tone board reed question
I have a spectratac receiver I am refurbing for a friend. It came with a K-1000 reed installed in the stock tone board. Now I know this calls for a TLN-8381 reed but the k-1000 seems to work OK. Its sensitive, seems to open on 200-300 hz deviation, seems centered frequency wise. Anybody with any experience on this, should a k-1000 work ok in this application? Anybody got a 103.5 tln-8381? Should I bother worrying about it? td wb6mie
[Repeater-Builder] Part 97 question reference to Repeater control
Part 97 debates are not allowed on the list, but this is not a debate. It used to be that repeaters had to have some means of control (Control link or telephone), and that they had to cease operations within 3 minutes of failure of the control link. Is that still in Part 97, and if so... WHERE? I can no longer find it under any rules that apply to repeaters. I can only find any such reference under the Telecommand Station rules. Please cite the specific section that requires control (other than Automatic Control) of repeaters. Was that section removed? Thanks, Joe M.

Otherwise you might consider a turn-key repeater from the Repeater Builder folks, Hamtronics or Maggiore. I would not suggest you go with the Midland 13-509 conversion because after all the work is done... the receiver is just not the best performer. I completely disagree. I've built a couple of 13-509 systems continue to service a couple of others. Given what it is, it performs exceptionally well. I have one literally sitting in the middle of downtown LA @ 1000 ft. AMSL with nothing but a notch duplexer between the RX the antenna, it hears quite well with no IMD. Bob NO6B

If the amateur station is under telecommand (remote control, see 97.3(a)(43) ), the 3 minute control link malfunction rule applies. So if a repeater is being operated under remote control, this rule applies. Bob NO6B
