RE: [Repeater-Builder] Wacom WP-639 Duplexer question
What repeater are you running? Is it a GE Mastr II by chance? Andy From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of RichardK Sent: Wednesday, September 08, 2010 3:11 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Wacom WP-639 Duplexer question Good evening, our club has a Wacom WP-639 four can duplexer as part of our repeater system. Input Fq is 147.915 and Output Fq is 147.315. We have a 600kHz (+) offset. Very simply, our main problem is when we run the transmitter at full power 100 watts, there is a HUGE desense on the receive side of things. When we drop the transmitter power level to around 20-50 watts, the receive side opens WAY up to a large area where people can get into the repeater. As we begin to bring up the transmitter power, white noise begins to appear and the receive side starts to desense again. All the cables have been switched to double sheilded cables and all the same wavelength in length. We have the duplexer seperated sheilded from the transmitter preamp parts. We have not replaced the antenna feed coax with double sheilded coax yet. Antenna is a Hustler G7 atop a 55' mast. The duplexer was retuned just over 1 year ago. Any suggestions as to what we could look into next? Some of us believe the problem is with the tuning of the duplexer receive cans. Thank you very much.

RE: [Repeater-Builder] Unlawful in Il to Rebroadcast Public Safety Communications
The Federal Law says only that is it illegal to divulge radio traffic to third parties or to use it for personal profit or gain (ambulance chasers), when I lived in Philadelphia in the 60’s the Phila PD used to pipe their communications into the various radio stations and TV Stations—then they passed a anti scanner law.

RE: [Repeater-Builder] Trbo to be DOA 2012 Say Hello to Tetra
Well-there are several companies which are making 12.5 KHz conversion kits for Mastr II's and other radios, where are not type accepted for commercial service but can be used for ham service, the big issue to me is that the commercial community has years to prepare for 12.5 Hz narrow banding (below 512 MHz) and the vendors have been building systems capable of both wide band and narrow band use for many years. How long will it take to get these same vendors to start providing both 25 and 12.5 and then 6. 25 KHz radios for ham service? You cannot expect hams to simply dump their existing radios and buy new ones-public safety and LMR operators have had a lot of time to prepare so we should have the same option. The bad news is that wide band commercial radios are going to be plentiful and cheap in the next few years as commercial operators are forced to change to 12. 5 KHz channels, it would make more sense for us to be able to take advantage of these WB radios and stay wideband for a few more years than race to keep up the LMR folks.

Another way is to set your dialer, if possible, to allow outbound 911 only and reject all other call requests.

Actually, there is still a legal question as to whether equipment that was not type-accepted for narrow-band originally will still be legal if the transmitter is narrow-banded, ie, deviation turned down. The FCC has yet to clarify much of anything like that. A big can of worms and there seems to be a lot of people on many groups who live to post various FCC rules along with their interpretations. Bores me to tears to try and read the legalese these folks spout. Some key points if I may... The narrow band physical mod is to the receiver. The transmitter is not a mod, but typically a standard deviation and audio level adjustment. It is the responsibility of the License Holder to ensure the emissions are legal. I personally have been told by more than one FCC Field Agent and a former Office Chief... (still working at the FCC in a higher capacity) they are not going to get excited about properly upgraded equipment properly running within the limits of the license requirements. The above has proven to be the case the few times I've had site interactions with the FCC. I've never seen a Field Agent walking around with a type acceptance list or computer doing said look-ups. s.

I only spent an afternoon, but the technology is fascinating. Two way communications from selected sites to the meters will eventually be implemented. If the customers meter does not have a direct path to the site it can relay it's data through another meter that it has connectivity to. Kind of like a big mesh network. Every meter is also a repeater. It is eventually going to be a two way network, not just for meter reading. The power company will be able to control the load of devices in the customers home or business location (presumably for a discounted rate) as the power company needs to adjust demand. A good example would be to shut off your electric hot water heater for 5 minutes. This would probably have no direct effect on the customer, but would be a great cost saver for the power company. Using spread spectrum and 900Mhz, the range of this system is amazing. Very few meters are in dead zones.

450-470 MHz is alive and well and still full of public safety, business and other users (including, of course GMRS and Family radios), and it won't be going away anytime soon-every new allocation made by the FCC in the future is liable to be broadband only so the channelized stuff has to have a home too-although the Public Safety folks also have 14 MHz of new 700 MHz spectrum which is starting to be used for channelized systems-all P25 and on 12.5 KHz channels moving to 6.25 KHz over time.

RE: [Repeater-Builder] Securicor 220 mhz repeater????
From a friend of mine who runs more commercial 220 MHz system in the US than almost anyone else. As far as the Securicor radio, I don't think it programs on ham bands, and only later versions of the mobile had talk-around (simplex). The repeaters were set up for trunked use only. They make attractive ballast pieces for trebuchets and sailboats, though. Todd Ellis, PMP Phone: (919) 379-5284 Cell: (919) 215-4161 E-mail: tell...@nc.rr.com Ubi caritas, Deus ibi est.

If anyone has schematics or a service manual with schematics it would be greatly appreciated and would aid my efforts tremendously. Or any information on the mobile radio that was used with these would help as the repeaters seem to share the RF and SPU boards minus a few components here and there. It seems to be technology that has been allowed to die. The company that designed this stuff was called Linear Modulation Technology out of England, a subsidiary of Intek Global. These were later produced by EF Johnson as the Viking LX series. It is unknown if Midland while under the Securicor name actually produced them or not. Mine has a EF Johnson klingon added with the wrong shade of white paint and a Securicor sticker slapped on top of that. The system used is called Linear Modulation. Similar to SEA's ACSSB system, but different enough that the two companies products are incompatible. Apparently the FCC didn't care what people used on 220-222 MHz, as long as it fit into a single channel. Both are Upper side band designed to fit in a 5kHz wide channel. DSPs spilt the audio passband in the middle for insertion of a pilot tone while the upper portion of the original audio is transposed above the pilot tone, you get about 3300 Hz of audio bandwidth, about 400-500Hz of split for the pilot and the rest is channel guard. In LM, the pilot tone that is used for AFC and AGC. In ACSSB the pilot tone also serves to send trunking data, while the audio is compressed and expanded for noise reduction. In the Securicor the receiver brings the RF down to a 12.5kHz second IF and the DSP goes to work on it as a software defined radio. As a matter of fact this is considered the first SDR made, with patents back to 1991. The transmitter is basicly a phase method SSB generator that uses the DSP and 2 DACs to generate the 90 degree phase shift. there are like 5 mixers on the RF board.

RE: [Repeater-Builder] Re: what pac-rt means
George-I will let the Motorola guys on here answer most of your questions, I tend to stay on the GE side of things, however, the HT does not become a repeater when placed in the cradle, but a simple HT turned into a mobile, The HT's generally had a single channel in them, with PL, not sure about that one, the switch I believe you will find was supposed to enable and disable the PAC-RT that was attached to a different mobile radio mounted in the trunk and with a control head up front, therefore the combination you have should work as an HT and also as a mobile with amp but not as a repeater.

RE: [Repeater-Builder] what pac-rt means
Just to be clear the drop is planned, it is designed so that when multiple cars are on the same scene only one of them has a PAC-RT in operation, otherwise it would be a zoo-so the drop is really the synchronization of multiple PAC-RTs, the first system I was involved in was in the mid-1970's and was the state of Ohio, then on to California and the CHP, and Nevada used to use PAC-Rts. Also, today you can find a lot of the mobile repeaters around-and they make good portable repeaters-HOWEVER, most of them, at least the GE ones, made sure that the receiver sensitivity was very poor so that it only picked up local HT traffic. If you have one you will find that in the first receiver stage-the ICOM and associated components, there are a number of caps which have been left out in order to keep the receiver deaf.

Correct—David and it DID work ONLY when they keep their radios in the charger—on the CA CHP system if you listen on 154.905 you will clearly hear the beep as they exit their car—it is also a great way of keeping track of CHP cars which are close to you since all of the traffic they receive on their low-band radios is rebroadcast on the 154.905 channel if they do not have their portable in the charger and most don’t.

We installed a GE Mastr II running into pre-amp, a BandPass and then a 6 can duplexer. The antenna is Hustler G7-144 and 1/2in hardline up 65 feet. The duplexer was set up with service monitor at the test site prior to installing it here. When I go above 10 watts out all we hear from the users is a lot noise and very little voice. As the power goes higher (when radio heats up) the noise gets so bad that we can not make out a thing the people are saying. The SWR between the radio and the duplexer is 1.1 at 5 w and 1.15 at 7.5 watts. Of course as we go up in power to 20 watts out we have 1.3 SWR. On the antenna side of the duplexer the SWR goes up to 1.4 at 20 watts and 1.2 at 7 watts and very little at 5watts (meter hardly moves). What model of watt meter are you using? Typically the accuracy gets worse at the low end of a particular range, so unless you're switching ranges/replacing slugs to keep the forward indication at the top 50% of the meter's scale, the accuracy may degrade. Could also be a TX that's going dirty at the higher power level. If you aren't using an isolator between the TX duplexer, I'd try that first. Sometimes the Mastr II RFPA doesn't like the pure reactance of the notch in the duplexer. Bob NO6B

The CAT5 cables are definitely shielded and I suspect that they are properly terminated. There are 10 CAT5 cables in total and an LMR200 cable. I suspect the LMR200 goes to a GPS unit which is on the tower. Six of the CAT5's go to the six panels and likely the other four are used on dishes on the tower that pick up and relay the signals coming to the tower. The VHF repeater is using a Sinclair 210-C4 on the top of the tower with the panels mounted just below that (approx. 10 feet down) The repeater is multicoupled to the 210-C4. All feedlines for VHF and UHF antennas is hardline. The power supplies for the panels are switching type. The noise is across the VHF band. Thanks for the comments so far. Has the Canopy system been installed using shielded cat5/cat6 cable? The EMI certification is only applicable if shielded cables are used (and properly terminated). What sort of antenna is your system using? How much vertical/horizontal separation from the Canopy system? Above or below? Does the Canopy have one or two cables running to each panel? If one, the power, sync and data is carried on the same cable. If shielded cable has been correctly used, the cable radiation should be minimal (provided good quality cable with 100% shield coverage is used). If there are 2 cables, the sync signal crom the Cluster Management Module (CMM) is on a separate cable. If that cable is not shielded, it could be radiating.

Hello all Have a couple of spectras, and a mrti 1000 phone interconnect I would like to set it up for repeater with phone patch. However i haven't been able to find a controller to connect the mobiles or a way to connect th interconnect to the spectra. could anyone help...
Re: [Repeater-Builder] Re: MSF 5000 CLB
Bob, Sounds like there's a problem with your Arcom controller (RC-210 I guess?). I've had mine bug out a few times where something similiar would occur, but it usually corrected itself after being reset. Could be firmware or a bad programming string somewhere... As far as the open squelch noise goes, thats something I've never encountered. I run 3 CLB UHF Stations and a CXB 900MHz Station with no cooling on the control tray and this hasn't happened on any of them. Is the white noise appearing in the hangtime only with no cor activity on the RX? Does this still happen when you run the MSF with the internal controller? Andy KC2GOW P.S.

She tryed to reset but the RX light would not come back on. So I just let it be for about two hours and tryed it again and the RX light came up. can anyone gave me any ides on what it mite be?

Eric, USE THE RADIALS. I tried using a couple that had lost them to the wind/ice also and the performance is pretty poor.

I suspected a jumper issue. But since it is so high up on a tower, I didn't want to take any chances while having the climbers rig the tower, and pay twice, so I went ahead and replaced the antenna as well as the jumper. Well, come to find out, the problem was that the LDF4-50 jumper came loose from the side arm, and the stress pulled the center pin in on the N connector, thus causing an arc condition inside the N female connector at the bottom of the antenna. To make matters worse, the actual N Female termination was half unscrewed from the bottom of the antenna. Once on the ground, I decided to unscrew it out completely. To my suprise, it looks like the antenna is actually terminated into something resembling a UHF male connector embedded into the end of the inner assembly, and a UHF female to N female adapter is screwed in at the factory, providing the N female termination as ordered I'm guessing that if some other termination (DIN or UHF) is ordered, a different adapter is screwed in. Anyone familiar with this adapter, or know where I can obtain said replacement adapter? I have some standard UHF female - N female barrel adapters, but they are much shorter and not of the quality like the Celwave unit. I don't want to trust a cheap adapter at 500ft in the air! I'll call RFS when I get a chance, but based on recent correspondence with them, I don't hold much hope getting any support from them. Sad part is their old factory in Marboro NJ was a mile from my office - in the early 90's telecom boom days I used to drive my truck there and pick 30 Statiomasters up at a clip, no cardboard tubes needed!

Here's the latest news: 1. We've set an introductory price for a package consisting of the 7330 Main Board and LED Display Cabinet combination at $399(!) plus shipping ($15). This is an *extremely* competitive price for a controller of this quality and capability. (If you haven't yet read the paper that discusses the philosophy behind this new series, please check out http://www.scomcontrollers.com/downloads/scom7330newdirectionspaper.pdf.) 2. The cabinets are finished and the Main Boards are being assembled. I've built some display boards, and wow, do those blue LEDs look cool against the black front panel and white graphics! (Yes, Mike, the Power ON LED is green.. :-) 3. We still have some work to do. For example, most of the testing is being done by Dave and Steve in their individual dungeons and needs to be moved to the LaPorte shop. Dave's working on the manual. And both guys are continuing to work on items that appear on our long wouldn't-it-be-nice feature list. 4. Rather than turn this thing loose in its current state, we'll be looking for a few customers to become beta site testers. We need folks with previous 7K programming experience who can bridge over to the new command set with limited documentation. If you're interested, please note that the price will still be the same and you'll need easy access to your repeater site. On the other hand, you'll be contributing to an interesting evolutionary period in controller history. 5. While no one on the design team will be at Dayton this year, a 7330 will be displayed in the flea market area courtesy of a friend who'll be making the trip.

Re: [Repeater-Builder] Coax for cabinet and for feedline - other than hardline
Is LMR-400 a good coax to use for my 70cm repeater feedline. My feedline is 130 feet long and located at my house. Should I really go ?to hardline and replace my LMR-400 feedline? If so what diameter? Will it really be worth the cost and trouble to run it through my attic and into my house? It is a wise move. I used about 75ft of LMR-400 to get my UHF machine on the air in a pinch. This install unfortunately became permanent. For a while the LMR is OK but after about a year or so in the weather you start getting duplex noise occasionaly in the machine. For a 130ft run Andrews LDF4-50A (1/2) or eqivalent is fine. If you want to spend the extra money LDF5-50A (7/8) is a lot thicker/stiffer but has about .8db of loss for 100ft @ 440MHz. Your article indicates that some LMR-nnn coax are OK for cabinet connections. Is LMR-400 Ultraflex a good choice for cabinet connections? I am using RG-142B/U now for my duplexer connections (an Angle Linear custom made duplexer, bandpass cavities, and preamp). Should I use RG-142/B/U for my (30 inch long) Tx to duplexer run also? The RG-142 is OK for duplexer cabling. Only improvement here would be to go to RG-214. As far as equipment jumpers RG-214 would be the better bet especially for the TX side of the duplexer. I would like to keep my new Daiwa CN-801 (UHF connectors) SWR Power meter in the Tx line permanently. Is this a good idea? It is comforting to see the power and SWR at a glance. Bad Idea. The Daiwa is a nice meter, but is not exactly the best shielded device in the world. Especially with UHF SO-239 connectors on the back. Just adding more loss and another source of noise/desense in the cabinet. I am using a Diamond X510MA (17 feet long with a UHF connector) dual band antenna at 65 feet high. Should I be using a different antenna for my repeat operation? If so, what antenna? The Diamond is fine in my book (prefer with N connector but whatever is available). If you want to go commercial grade, the RFS PD-1151 is the equivalent to the 510. Otherwise if you want to really look for the horizon with the most gain, the Andrew or RFS 22ft 10dbd verticals are really nice. Is the Kenwood TKR-850 repeater a good unit. I just ordered one to replace my Micors. I have nursed my two Micors for the last year, and just gave up on them. One problem after another on both units.
