(Also hope to have battery backup.) Can the 100-watt UHF PA be jumpered from an intermediate stage to the filter, bypassing the final? I seem to recall these would run at something in the 10-25-watt range with such a mod. The driver is 40 watts, just bypass the final board. But if you're really trying to safe your landlord's electric bill, the ferro power supply is really what you should be eliminating. That's a real beast of a vampire.

RE: [Repeater-Builder] Re: Adding capacitors to lower electric bill
My Elmer, W6NTK (SK) his son worked for PGE. I was 12 years old then but I noticed at his power panel he had a bank of capacitors wired into his panel. He explained to me he had these on to eliminate the big surge when the well pump or any big loads came on. He asked if I remember seeing these capacitors along the power lines. He explained that the power system was a transmission system and that to keep the system in tune they had to add capacitance along the long runs to balance the system. And that he was doing the same on his panel. I asked so does this lower your bill and he said not really but it can reduce spikes in the draw. He then tried to explain some math and being 12 that started sounding like school work and he lost me. Thank you for brining this up I have not thought about my Elmer in a long time. I wish I had paid more attention to some of the things he taught. Hopefully the group can turn mu 12 year old memory into some theory this old dog can chew on. Maybe I can use this info to reduce power usage at the repeater. :-) -Kevin _ From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of ae6zm Sent: Saturday, August 21, 2010 12:18 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Adding capacitors to lower electric bill When in comes to matters of science, there will always be some who step forward with anecdotal 'evidence' that they have experienced something that contradicts accepted scientific knowledge. Using caps to reduce your power bill is one of those myths. Your power meter is a true watt meter, and is very carefully designed and tested to measure, react to and record only true watts, and not react to reactive power. (pun!!) Yes, installing corrective capacitors can reduce your power bill, but not because it changes your meter reading; it doesn't. For industrial users, a poor PF results in penalty charges from the utility, and improving the PF by adding capacitive VAs ( or KVAs) can reduce the penalties, thereby reducing your bill. This is not really a repeater topic, but power bills are a real part of repeater use, so it is useful to understand the real 'science'.

RE: [Repeater-Builder] Re: Advice on 40 year old radio tower
If you can use it as is, by that I mean if you are going to use the antennas and feed line that is there then go for it. Run it till it falls down. Do not climb it, do not add to it. Just clear the guys and base of the tower of the over growth. Never work at this site alone. Have a safety person watching the tower at all times while workers are under it. He needs an air horn/whistle or some signal to sound the alarm to get to the safety area. Make sure you have safety routes and zones while you work under it.

The repeater is on 146.850 (-600 KHz), with the antenna system about 120 feet up a water tower. The repeater itself is an Advanced Communications System KRP-5000 running 35 watts through a set of 4 WACOM cans. The feedline is 7/8 hardline feeding a DB-224. All jumpers are RG-214 MILSPEC with MILSPEC connectors. This system has been in service for years and has never given us any problems, and we are the only ones at the site. To be clear, the interference we are experiencing is clearly audible on the repeater input. I have the capability to monitor via telephone and have heard it on the receiver, and I've also traveled to the site and heard the interference on my mobile radio hooked to the repeater antenna. The interference is also audible on the input in various locations around town. Also, the interference can be heard on the input regardless of whether or not the repeater transmitter is on. It also continued to be present during several days of continuous heavy rain. The interference typically shows up at least once a day, although some days (rarely) it does not show up at all and other days it will show up several times. Lately, it's been making an appearance around 10 a.m. and hangs around for an hour or two. As it begins to disappear, it sounds as though it is moving off frequency. This interference has also been heard on at least two other repeaters in the area. One is about 22 air-miles from the 146.85 machine and is on 145.110 (-600 KHz). It has also been heard on or near the output frequency of that machine, and one evening I tracked it from about 145.120 to 145.190 as it swept through each transmission. The other repeater it has been heard on is 147.300 (+600 KHz). I also have reports from a neighboring county a ham/deputy sheriff there has been hearing it on VHF public safety frequencies. As you can see, it's all over the place. I've been working with the owner of a local paging company and we can clearly tell that the data we're hearing is coming from 152.480 and 462.775. He has two sites (about 20 miles apart) that simulcasts on both frequencies and when those transmitters are active it's easy to tell that the data is the same. He also tells me that he can key each transmitter separately and the data from each transmitter will be heard on our repeater. We also believe that there are other systems on nearby frequencies that are being heard on our repeater, specifically 462.850 and 462.925. I've run IMD numbers on everything I can think of, but can't come up with a common thread. For it to be moving all through the 2-meter band and for it to be mixing with several different frequencies, it seems to me that it's got to be very ugly and unstable. What am I missing here?

Normally these links are run via dedicated microwave links or T1 lines (i.e. on all the time). I'm thinking perhaps of using VoIP or simply media player style audio streams where when one machine is active it sends the command tones and audio to the other one. IRLP or Echolink could be an external option, but why not use the built-in native interface that has worked for many years since the connection to the repeater is fairly simple.

Probably a defensive flying endeavour to help them see and avoid the insane amounts of traffic at the coast. Always a nice option for the PLT if you have active radar and can see other people trying to run into you, but they're talking to ATC also... just a secondary information source.

Buy an HT if you're wondering if the big iron is up and active... :-) Amateurs on the coasts near Naval bases regularly receive unintentional interference from Navy RADAR, inland it's usually aircraft (think about the ERP/power requirements to hear OFF-FREQUENCY UHF noise on your Amateur Repeater... whew... those boys have some power on board!) or fixed installations, and can be DF'ed (if a ground source) right to the antenna. Of course, not all of it is off- frequency... depending on the RADAR or Comm system. A number of Colorado Amateurs DF'ed the EPLRS noise at Buckley AFB right up to the antenna (with appropriate permission to be on-base at the time) and later some careful negotiation with the system manager included pointing out that if he didn't notch out the Amateur repeater inputs (which the system CAN do, since it's so frequency agile), he was basically giving away the dates/times of active training missions to anyone with an Amateur UHF HT talking on a repeater in the area, along with just general begging... I hear that this is very location dependent, and probably also had to do quite a bit with the fact that one of the Amateurs talking to them was a RADAR/SIGINT expert from a past life... I think. He won't say. Hah... those of you who've done those jobs get it when I joke about that. Anyway, haven't had any EPLRS noise now for many years here in the Denver area...

Bob Ok so much for the software. One other user today mentioned a possible issue with another repeater. 147.300. All I had been looking at with the software were the transmitters at his site. Ok so I plug that into the mix of xmiters in the software and bingo. A+B-C 146.70 + 146.70 - 147.30 = 146.100. The repeater 146.70 does have a circulator. Again this intermod is not my best area. I had the repeater owner keep the 146.700 xmitter up them had him hit the 147.30 with an HT and yep we got a burp of noise. But he heard at least 3 repeaters come up. So if this mix is the one that is causing all the issues, now we just need to find where the mix is occurring. Any ideas on where to look? As you can see in the full printout from the intermod tool.

Both repeaters have BpBr duplexers and both have isolators on their outputs. 73 DE N0MJS -- Cort Buffington H: +1-785-838-3034 M: +1-785-865-7206 Yahoo! Groups Links

RE: [Repeater-Builder] Re: radio shops without a vision
True, but most of my business clients don't want to give people full cell phones, else they're on their phone much of the day talking drama, drugs or where the next party is... I got one customer back from Nextel because his first bill for only one phone was $1600. Seems it costs real money to call South America and talk to the family all day long (for a month). Ouch! I would never hand over a full open phone to any employee! Phone accounts can be locked down to local only and even call groups. Cough, cough... Unless his link paths are really blocked, regular rf links would be a cost effective way to go (unless you have a microwave hop handy). It's my opinion that current VOIP Linking is still way to Jerky for the typical consumer to deal with. All the delay, switching, connect times and choppy audio can quickly frustrate the users. It's hard enough to get them to press the ptt button before they start talking. Yea the on demand stuff sure. Let me clarify. VOIP audio links Full time dedicated just like a control link loop on wire line. I would do some VOIP to the DC/TONE remote on bases at each of his sites. Or do it the old way and get some tie lines or dedicate a phone line. but now we are adding recurring costs. We use some VOIP switches at work from SONUS. Seems to do very well, you would not know your were voip. But the IP path is dedicated backbone for VOIP. :) many ds3's! Kevin Yahoo!

Mostly in junk yards. That was after the operators of the yard gave up on the cordless phone with the antenna kits! The suggestion to use a PTT service is only 9.95 to add to existing service. I was assuming employees already having some sort of cell service. If they do not then a system solutions is the way to go. The one 60 mile hop the poster mentioned is what is going to need some engineering and brings cost and most likely ongoing expense to the solution. The best RF based solution so far sounds like the voice over IP linking. Unless he is in the central valley of California, then just about any of the good mountain top sites will cover him! Cellular sales folks would jump on the opportunity to do something with this. Those folks are more aggressive that the sales folks for 2 way in the hay days.

Figure Cingular units cost min $29 per month just to run the ptt feature. 20 units is an easy $580 a month just as a regular ongoing cost. This type system is where Land Mobile Radio (LMR) could provide a much more cost effective solution at a much reduced ongoing cost over Nextel and/or Cingular. Someone with their well thought out planning hat on would also make the system perform both in and around the store locations just to impress and expand the system to the local area. Cingular's push to talk feature might be a solution. The problem with many of the older radio shops is the lack of vision... in the old railroad days we called this sleeping at the switch. I'd be over to the customer location the next day asking to demo the equipment, showing system diagrams and showing off the portables that would work through the system... also showing how much the ongoing costs would be for both systems over the next 3 years. Most people can see that far ahead. About 80% plus of the old time radio shops never seemed to wake up or warm up to the real world... many have gone poof. cheers, skipp Yahoo! Groups Links Yahoo!

A quick walk through said all of the precious metals were long gone, heavy copper wire, large pieces of aluminum anything from the cornucopia horns, copper wave guide, brass fittings ... all of it gone already. I scrounged a pile of HP test equipment, Motorola MSF5000 and Syntor manuals, a few rolls of solid conductor wire, a couple of handfulls of coaxial adapters, some patch cords and other miscellaneous.

Last time I saw a crew at a site I walked up and talked to the foreman. They were adding a new GPS antenna and associated cabling, so they had no heliax on that trip, but the foreman said that if the job had been feedline replacement or new install a case of Bud would be the price for any scrap. This was in Los Angeles, but he commented that a while they were pulling down several runs of 7/8 and replacing it with new and they just cut it up into easy-to-handle chunks with a sawzall and tossed it into the truck for recycling, but if a ham wanted it the cost for the extra effort for pulling it down in full lengths would have been a case or two. I've not been lucky enough to catch a crew before it was cut up (60 chunks of 7/8 each about 5' to 6' long aren't worth much except in scrap) but there's always next time. So keep an eye on the cell sites as you drive by, and if you see a truck there pull in and strike up a conversation. It might be a service man, or it might be the planner for a construction crew.

Is there a printable parts list for the parts I need to order to complete these boards? If so where can I find it? Are these units in stock, what is the delivery time on these units? Is there a discount if I buy as many as six of these controllers? Thanks, Paul Paul At 11:44 AM 11/25/2005, you wrote: Kevin, Like I said, I have never owned a NHRC product, I have used 5 MCC controllers in the past and have been very happy with them. What drove the decision to try NHRC was the fact that I have 8 repeaters to build and their price fit my very low budget. I talked to a Rep from NHRC and he quoted 35 bucks each on a quantity of 10 (only need 8) or more units, got the email. A couple of months later after I had scraped the money together I talked to a different Rep and he said, no way can we sell them at that price. Like I said, I may have to buy the controllers from them but I will not be happy doing so

RE: [Repeater-Builder] Illegal uhf repeater
Well, if the repeater is up and abandoned why not use it? And if the owner does show up offer to help with the upkeep. That is if we are talking about an amateur repeater. One of two things will happen, You will find out it is not abandoned, In which case maybe just support that repeater and it will get used, then you will not need to build one. Or you will confirm it is abandoned. In ether case sounds like you have a repeater that needs users and you do not need to build another. I did say need, want is a different animal and I tip my hat to anyone that wants to experiment and build systems. I do it for fun myself. I build them for others for the fun of building. I think the best advice was from Eric, go back to your co-coordinator and request another pair.

I am assuming that we're talking about Amateur Radio frequencies, not commercial. Did your local frequency coordinator assign you the frequency you want to use, not knowing that a repeater was already on that frequency, or did you select a frequency without running it by your coordinator first? Looking at the situation another way, have you reported the subject repeater to the coordinator, so that its status can be investigated officially? Is the subject repeater being used by anyone on a regular basis? Is it identifying in accordance with Part 97? I strongly urge you to NOT just DF the transmitter and take it down, as you may quickly run afoul of the law. It may be better to just pick a different (and properly coordinated) frequency pair, and let the coordinator handle the allegedly abandoned repeater. 73, Eric Lemmon WB6FLY nebraska_ham wrote: please help us and tell us how we should proceed. we are attempting to put a uhf repeater on the air and someone is using the frequency we intended to go on. the repeater has been abandoned as the repeater owner moved away several years ago. i am guessing that we just df the transmitter and take it down. attempts to find the repeater owner are useless as he left the state years ago. we heard that the owner who abandoned it is now on the west coast, there are a few rumors that he is in the military out of country. advice is appreciated here since the fcc is so useless.

RE: [Repeater-Builder] Still after
Neal, I do not have any Pic's that I can locate. This was built before digital cameras were affordable to the common man. We did take Polaroid's, but whoever has them by now are well faded. There is one fellow ( forget his name) on this list that took my description and made a very nice set of cavities. He really went all out, he had machining skills and equipment. He almost duplicated a DB products can when he was complete. He used fancy finger stock and piston caps. Very nice job. Maybe we will get him to chime in. The example I followed to make the loop was the write up on converting the db products pass cavity to a pass/notch. I have seen many articles on the web on making the loops for the cans. A very good write up on this by Jeff DePolo can be found at this link. http://www.repeater-builder.com/loband/ I did not use his method of using coax stubs to make the notches. But this is a good source of information and constructions techniques. The project was done by myself and a hand full of other hams. We took a look at a wacom duplexer and did the best we could with common parts to make something like it. Each person in the group had certain skills or equipment for making the parts. The first one we completed checked out on an IFR 800A with 22db of notch with .6 or so db of insertion loss. (not bad, could be better. Maybe using Jeff's notch setup would be better?) We compared this to others that had made these duplexers. What we found was the construction of the top plate was the most critical part of how well the cavity would work. It was common to make the top with a paint can lid or sheet metal. Theses all has poor notches and high insertion loss. The thick aluminum plate seems to work the best. Also the plexi-glass stabilizer in the can prevents the long tuning rod from moving around. Also we were the only folks to use the stove pipe crimp to fit the cans. This made the cavity very strong. all others just soldered the cans with a butt joint. We used no drawings just looked at the wacom and other coffee can cavities and went from there. I was not the first to make a set of coffee can duplexers but think we took them up a notch! (pun intended) I think I might be the only repeater still running a set. Currently the longest running set. The picture on the repeater site on my web page does not show the duplexers well as they are back in the corner behind the repeater racks and coupler array. I will see if I can get some better pictures. It is ruff as I am on the east coast now and repeater is on the west coast. I have not been to the site in 7 years. The next set was done with irrigation pipe, Yet to be finished. Still sitting here somewhere. I think I am using one tube to hold all my mobile antennas! If you have someone that is good with a tig you can weld them up. If not then just make the bottom just like the top. This is how crafty we got. to make the top plate we did not have a lath to make a clean round disk. We chucked up the square plate in a drill press at low speed and made a cutter that was held in place with the bench vice! Touched it up on the sander and bingo! It is not that critical when making LB cavities. You do not need invar or copper plating or anything like that. It is just not that much difference at these frequencies. Now vhf hi and up and you bet! It is very critical what you use and how you build it. Shoot look at the heliax cavities out there! You can not get much cruder than that in construction.

RE: [Repeater-Builder] Still after
First get a stove pipe crimping tool, and a stack of big coffee cans.cut the rim off one end and use the crimpier to prep the edge cut the bottom out of the next can and rim as above. stick the crimped edge into the bottom of the next can, check for fit. do this till you have a stack taller than 54". Make four of them. wire wheel the joint to prep it for soldering. Assemble the stack of cans, use three pop rivets around each seam to hold it till soldered. Then get your propane torch and plumbing solder, sweat the joints. Oh yes, in the third can from the bottom, mount a disk of plexi-glass with a 9/16th hole in the middle. This will steady the tuning rod later. To make the top of the can use 3/8ths or 1/4 inch aluminum plate. Fit it flush with the top of the can. drill and tap or use self taping 8-32 screws to hold the top around the top. Now that you have this complete let's get some plumbing done. Get 2 each 8ft sections of 1/2 and 3/4 copper pipe. 4 1/2 copper pipe caps 4 4ft sections of 5/16ths all thread rod with a bag of nuts to fit., 4 3/4 pipe to 3/4 treaded copper fitting. four 3/4 threaded pipe caps. By now you should be getting a picture of this. cut the pipe in half so you have 4ft sections. take one end of the 3/4 pipe and cut small long triangles around the end. you with squeeze this to make it like fingers down to the 1/2 size pipe to slide through. take a 1/2 pipe cap and drill it to let the all thread through. take two nuts and secure the all thread to the cap. solder this to the end of the 1/2 pipe. now solder the threaded fitting to the top of the 3/4 pipe that you made the fingers on the opposite end. Feed the 1/2 pipe with all thread into the top of the 3/4 pipe. gently push it through the fingers you made. Test this for good even firm contact. I used so no ox here just before I did the finial tune. Take your top plate and drill a hole to accept the threaded top of the pipe. Drill and tap the 3/4 pipe cape in the center top to take the all thread. put this on and secure to the top using spacers as needed to secure the top to the pipe securely. Get some nice knobs at a swap meet and you now have a basic cavity. There are many ways to make the pickups. I made my cans pass/notch and used a so239 panel mount tuning caps out of the finals of a RCA car phone. and the loops were made from left over 1/2 pipe. I flattened it and sanded the sides to separate it into two flat peaces. We made the loops 2 3/4 inches long or 5 and 3/4 memory fades. try it and see what works it is cheep to try. We had to tack some silver mica caps across the tuning cap to get the notch where we needed it. I have a set of these on the 52.6 -500 repeater in Bakersfield California. it is a 100 watt micor base running at 75 watts with a pre-amp. It has been in service for about 16 years. This is not meant to be complete instructions to build a duplexer. It is just meant to get you a usable platform to experiment with. with good construction skills and test equipment it is very easy to make 6 meter duplexers. You can take this basic setup and replace components and materials based on your skills and availability. Lowband is a fun world to play in. Don't let folks tell you you can't do it or it wont work. IT will, it does and you can.

RE: [Repeater-Builder] Re: Comm Spec TP-38
Reason I ask I have seen them act up when powered by the same power supply as the repeater and it did not quite have the current for the job. I would test it on the bench with an audio generator and O scope. I am thinking you have something ringing in the audio/pl chain. Also drive levels (audio could be problem) TP-38's can be quite old. what is the age and history of the unit? when did it work correctly last?

Russ N4KOX I've also seen a DB224 that was modified by a ham. He cut the elements just inside the curve and spliced in tubing (that was picked so that the inside diameter just fit the outside diameter of the element) to stretch the element. Four elements times two upper and two lower cuts = 16 new joints. He used hacksaw cuts tubing and stainless steel hose clamps to verify the lengths. After the test was done the antenna was took back down and everything welded. The modified antenna was coupled with a new harness made for 2m and the combination outperformed anything else at that site. Mike WA6ILQ Yahoo! Groups Links Yahoo!

[Repeater-Builder] RE: GE part 95
Russ, After much digging and conversing with the current owner of the GE mastrII (M/A-com) Here is the part 95 type acceptance for the mastrII https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/Eas731GrantForm.cfm?mode=COPYRequestTimeout=500application_id=18541fcc_id=AXA9MZKT-114-K to search for the old GE numbers just put the AXA9MZ before the KT number. This is a quote from M/A-com on what to search for to find the cert. (they were very helpful with this info. And is excellent support for legacy products) Search for AXA9MZKT-114-K This MASTR-II was 450-470 MHz 100 Watt and used the 19A432679G2 PLL exciter with Audio Processor 19C321542G2. This exciter required the large ICOMs, 2PPM. The transmitter you have AXA9MZKT-114-C or D (There wasn't an "O") probably had an older exciter and may have been before the FCC grants went on line, therefore weren't part of the current database. I am sure the unit you have would have been approved for GMRS, but it is so old I can't dig back that far. You have to watch your power as I remember there was either a 20 or 60 watt limit, not the full power of 100 watts the unit was capable of. We are talking about filings that would have happened around 1975. I hope this puts the Mastr II being ok for GMRS to bed. As you see the PLL 2ppm with tx id KT-114-K is ok for GMRS and a valid certification is on-line with the FCC. Now there is a gray area for the other older mastrII's. They are older than the current FCC data base so do not show a certification and the Manufacture can not find anything that old in his records at this time. Russ, based on this I would revisit your fines the FCC hit you with and check your ID numbers. Another note. If you change out your exciter to the pll type you need to change your ID tag on the repeater so the FCC can properly ID the unit. I think I will put a copy of the part 95 cert at my sites just to be safe.

I either have to change the connector on the receiver so that the cable goes directly to the receiver without using any connetors to change from one type of plug to another, or find a special cable with an RCA on one end and a Type N Male on the other. My objective is to never visit the repeater site once this machine is done. And if I have to, I don't want it to be becuase I used a cheap connector to tie in the reciever. The receiver is the GE MASTR ER41. I'd rather just change the connector to a type N connector, but would have to widdle a little on the internal copper casing to put it in place. Question: If I install the type N connector, and there is a solder point behind the inside, am I going to run into troubles. I hate to cut into it to find that I'm opening a can or worms for noise to get in? Mathew I'm not entirely tongue in cheek when I ask whether you should be in charge of a repeater or installing one if you have not got the expertise to cut a bit of coax and fit a plug or socket.

Russ,
Re-read what I said. "But do meet part 95 a specks" I
did not say they were certified!
Just
that they do meet the standards for 95a.
All it
would take if for Motorola to file for modification of the certification. But
that will never happen.
And
that is all for this here.

GMRS
Hello All,
A week or two back we all where going back and forth on GMRS.
Well in the September 2004 Popular Communications page 36 starts a
wonderful story. Tittle "Can commercial-grade radio's be used for
GMRS.
The answer in a nut shell is NO. (part-95.129) No e-mails please
just read this will written article in Pop'Comm for all the answers.
Also read (63 FR 68975, Dec. 14 1998) It will make the answer very
clear as well.
Sincerely,Russ Stafford, EE,PE.GROL, PG-GB-01751.HAM,

RE: [Repeater-Builder] Micor 4 Channel Help Needed
it sounds like you do not have all the assy's for the radio. you would need a control group book and a connector tool to rearrange the cables. The best bet is to get the rig over to someone close to you that has a working test setup to check the rig. Or get a non scanning 4 channel cable and head from e-bay.

The wires you mention are going to the scan head. If I take Pin 4 to the connector #11 on the scan head, the volume goes sky high. Pin # 11 on the scan box goes to pin 21 on the control cable. Also, what is the brown connector used for? That is where the wire comes from pin # 4 is going to.

Trace pin 1 and pin 4 up to the head. Pin 1 is ground and is hooked to the shield of one or more of the coax conductors in the control cable and ends up on pin 21 of the head. Pin 4 is frequency 1 and ends up on pin 11 of the head. It is supposed to be grounded when the frequency switch is in the #1 position. If you have the wrong head for the cable then the frequency switch common might not be hooked to pin 1. This is common in situations where the installation had a channel scan head and the used equipment vendor gives you a standard head. When the channel scan board is added the control head frequency switch common is rewired and connects through the channel scan board and without the board in place the switch common isn't grounded. So just ohm out the F1 wiring and make sure it's hooked up. Then make sure that you have good elements in the F1 position. Depending on the history of the radio you very easily could have the wrong elements for where the radio is tuned. I once picked up a high-range (42-50mhz) low band Micor that had been a Red Cross radio - tuned to 47mhz. The radio had mid-range (36-42mhz) elements in it on some fire dept frequency. The vendor had grabbed a radio, a random head from a bin, a random cable, a random speaker, a random microphone. As long as they plugged together he assumed they were compatible. They weren't. As it turned out, I had a cable that had been pinned for a head configuration that had a 8 freq clamshell on the bottom with a systems 90 box above it. The box had a multiple PL encoder board and a channel-scan board in it. The radio came with a 12freq clamshell, the fancy cable, a Mitrek speaker and a bad microphone. It took a while with the Micor mobile book to figure things out. By the way, P901 is the control connector - the front of the radio. P902 is the connector between the center of the radio with the exciter. P903 is the connector between the center of the radio with the audio-squelch board. P904 is the connector between the center of the radio with the receiver.

Exciter: frequency 1 select wire from the Channel Element on the circuit board goes to P-902, pin 15. Receiver: frequency 1 select wire from the Channel Element on the circuit board goes to P-904, pin 2. Those specific pin numbers must be grounded for the receiver or exciter to operate properly. The usual policy was to ground the frequency 1 select on the center board (Control Board) at the factory on all one frequency radios prior to shipment.

Even moving the WX receive antenna away from and behind (it's directional) the 2m antenna didn't help. The solution was to connect a small Sinclair preselector in front of the WX receiver. These little gems are about five inches square, and have four helical resonators. I tuned it to the WX frequency, and eliminated the 2m interference. Preselectors are not cheap, but DCI will make you a nifty filter, similar to the ones for 2m, that passes just the NWS frequencies. It'll cost about $100, since it's a custom model. 73, Eric Lemmon WB6FLY Don wrote: I have a lot of Non Ham friends who use the Mur Freq 151.820 taking their HT To Little League Games Camping Etc , And I was going to set up a Legal 2 Watt Narrow/band FCC type accepted Radio , Whew had to get that out of the way first.

Here is what I am thinking, only becuase I can construct them very cheaply. As opposed to using a verticle, what would I expect if I used 4 10 element verticle beams, one point to NWSE, coupled with a power divider. My objective in this thought is to foward the gain to the areas that are of most interest. I am sure that I will see a few dead areas, but should be minimal. Has anyone had any expierience with this. This is for a 2 meter repeater, antennas will be up about 100 feet. Fed with 7'8 hardline. Thanks. Mathew Yahoo! Groups Links Yahoo!

Randy, Ok I have cleared my head. This is the 6 can helical duplexer. To get it to 6 meter you will have to cut the harness. I will look to see if I can find my notes on this duplexer mod.

RE: [Repeater-Builder] Repeater audio
Mike how did you do the link? did you make the micor 1/2 6 meter the other 440? or did you set up a complete two site ra/rp configuration like in the moto book? When linking two micor base or repeaters I use a line driver to the link xmiter.If for full duplex I use a 4 wire line driver. this puts the audio to the line 1 and 2 terminals on the back of the micor. Another thing to think about, you might want to check/ replace the old caps on your audio cards. they do dry out and I would guess your cards did not just come off the ass'y line :) Kevin -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]Sent: Wednesday, April 07, 2004 6:01 AMTo: Repeater-Builder@yahoogroups.comSubject: [Repeater-Builder] Repeater audio Hi all I've been watching the threads on audio reproduction.

If you were to listen to theaudio from the transmitters at each site they sound okay.However the audio out at the six meter transmitter after passing through the complete systemneeds some enhancement.
