I used some tonight on a connector and compared to Coax Seal or #33 Tape and 3M Sealant this stuff was a pleasure to use. The removal also impressed me, it was also quick and clean. I am mentioning this product in case you don't know it exists. I would also be interested in comments from those who have used it. I don't know how long it has been on the market, so I am also interested in longevity. Here is the information from the TESSCO Web Site. The TESSCO number is 360590. The silicone tape is available from Times Microwave, Andrew and a few others. I've been a very tried and true 3M rubber tape, 3M scotchkote and 3M #33 tape guy for many years. However, I've started using this silicone tape recently and am likewise very impressed. I usually make two complete layers, each one covering half of the previous wrap. One slice with a razor knife and it comes off, at that point I defy anyone to separate those pieces of tape, they have 'melted' into one solid, tight silicone seal. Just for safety I put some 33 over it to make sure it is protected and doesn't come loose.

Don't think of the feed system in terms of wavelength multiples - I'm guessing that's where your train of thought is jumping the tracks. I am thinking of it as a resonant resistor at the design Consider a two-element array. We'll ignore matching issues here to keep things simple. although they do have a major effect and I don't believe its possible to do so ?At the antenna feedpoint is a tee, and from the tee there is four feet of coax to each element. At some frequency (say, 150 MHz), the total electrical length from feed to element is some fraction of a wavelength; since I didn't specify the velocity factor of the coax I'm just going to pull a number out of thin air here, so let's say that our five feet of coax is 1.0 wavelength at 150 MHz. Now let's add 10% to the frequency, making it 165 MHz. The cable length from the tee to each element is now 1.1 wavelengths at the new frequency. BUT, the *difference* in phase between the elements is still zero! I think incorrectly , I am not going to pursue the maths as I am rusty ( did the ma a while back) but the feed impedance changes a freq shift to effect radion angle certainly ?It's the difference in phase that causes the beamtilt, and since the elements are still in phase, there is none. It's no different than keeping the frequency the same but adding identical-length extensions to each of the two feeder cables.it makes sense but I cant agree ? Did that make sense? to a segree , rationally if the freq is altered a retune will allow the aerial to work when retuned so the argument only effects an unaltered stick ? , I must admit I have not messed about much with low band stick of late as my primary ocupation is much further up the band with telephone and satellite gear --- Jeff WN3A _ Be part of history.

Has anyone experimented with such? I see mention of remote control generators so figure it should be doable. The current controller is a RLC-3 but that could be changed if it would help. The other obvious answer is to have the generator automatically come on when the voltage gets too low but I wonder how well that will work. We're in central Alberta, Canada so the days in winter are quite short and we can get 20 or 25 cloudy days in a row. We either need to put in a *lot* of solar panels or some other form of auxiliary power. Also the site may be accessible only by snowmobile for a number of months in the winter.We also will have to ensure that if the temperature looks like it's going to get colder than -35 for an extended period of time we'd better have the batteries charged right up as propane won't gasify colder than that.

RE: [Repeater-Builder] DTMF controllable propane generators
discussing this with a motor engineer who really knows about lpg/propane this was his response How far below ground level do you need to go to get away from the atmospheric temperature variation? Enough distance below ground with an insulated door will see a temperature consistently over 0C. If it's on a hill, go part way down the side of the hill and do a horizontal bore shaft and put the tank in the end of the shaft or a small carved room if in rock. The shaft only needs to be big enough to crawl into or for the diameter of the tank, whichever is larger. If the ground is unstable, large diameter concrete drain pipes can be used to form the shaft. All of the pipework including the outlet of the relief should be piped away in hose, with lagging if necessary. The idea is to make sure that cooling such as from conduction of heat away along the lines does not exceed the rate at which heat in the ground is able to transfer into the tank to maintain a consistent off temperature. Is it going to be liquid withdrawal or vapour? Small engines will be vapour, while bigger ones will be liquid. The difference is important because it affects the rate of tank cooling while the genset is running. In a vapour withdrawal system, the liquid in the tank is continually boiling off to maintain vapour pressure and the latent heat of vaporisation of that has to be compensated for by heat going into the tank from outside. Liquid withdrawal has a proportionally smaller rate of vapourisation relative to rate of fuel withdrawal as it only has to vapourise a quantity of liquid proportional to the liquid withdrawal to maintain vapour pressure. In a vapour withdrawal system, you'd virtually have to heat the tank from the waste heat (not exhaust) of the genset. With liquid withdrawal, the majority of the latent heat of vapourisation is handled in the convertor at the engine. An engine oil cooler under the tank would be an effective form of heating, but might need a pair of bypass thermostats, one to stop excessively cold flow and another to stop excessive heating of the tank... hope that helps To: Repeater-Builder@yahoogroups.com From: [EMAIL PROTECTED] Date: Fri, 9 May 2008 07:34:05 -0500 Subject: Re: [Repeater-Builder] DTMF controllable propane generators Tony, Wonder why the commercial power would cost that much.

Several years ago I decided to go back to the gym and get back into shape. I went to the doctor for a physical which included a blood test. As part of the test they look at two liver enzymes. One of mine was high just outside the normal range. The doctor said to come back in a month to retest. The next month the first enzyme went higher and the other one went off the scale. I had a liver ultrasound which came back normal. He then ordered a liver Biopsy. Not a pleasant experience!!! The biopsy came back almost normal other than signs of age and a body that had been neglected. Each blood test after this my enzymes started coming back into range. When I (we) tried to figure out what had happened the only thing that we could link it to was MEK. I had just finished building a small experimental airplane that is made up of aluminum tubing and fabric. All of the aluminum was cleaned with MEK and the glue contained MEK and was thinned with additional MEK. All of this work was done with large opening doors and most of the time had a fan running. Most of the time I did not use gloves. The facility I work in has MEK banned. Not due to my experience but because of environmental concerns.

RE: [Repeater-Builder] 19 rack positioning question
Very familiar with these , wonderfully well made and will outlast all of us although in my part of the world they have fans Std . To: Repeater-Builder@yahoogroups.com From: [EMAIL PROTECTED] Date: Sat, 24 Nov 2007 19:39:45 -0800 Subject: RE: [Repeater-Builder] 19 rack positioning question I put a VHF repeater together this summer in a Stromberg Carlson cabinet that the phone company retired and had to install a fan in the top of the cabinet to get the heat removed. The cabinet was insulated with one inch foam on top, bottom, sides and doors. It was a side-by-side rack cabnet with 19 inch rack on one side and 26 inch rack on the other. By adding some 2 inch spacers to extend the rack rails forward, a GE Mastr II repeater fit on the 19 inch side, and by removing the 26 inch rack rails, the duplexer fit into the other side of the cabinet. There were places for two exhaust blowers in the top of the cabinet with a flapper to close off the blower hole when it was not energized. The air entered the cabinet directly under the 19 inch rack side, with an RFI screen covering the hole and an air filter to clean any debris out of the incoming air. The whole thing sits up about 2 feet off the ground, so it is real handy to get at the equipment. The 19 inch rack side hinges out and access to the rear of the repeater is excellent. The GE power supply is on the bottom, with the controller above it and the repeater at the top of the rack. I originally mounted the 50 deg C (about 105 F) thermal switch on the power amp heat sink, but found the temp got too high in the cabinet before the fan came on. By mounting the thermal switch to the top plate of the power supply, I got the best temperature control. I only used one exhaust blower as the flapper keeps the other hole sealed. On a warm sunny day at 7000 ft, the temp inside the cabinet rose to an uncomfortable 120 degrees (80 deg outside) until the fan was installed. With the fan controlled by the thermal switch on top of the power supply, the temp felt as cool inside the cabinet as outside the cabinet. I should mention that this is an outdoor cabinet and is sealed completely to keep any water out. All entry points for wiring and coax are on the bottom of the cabinet. Exhaust air is into a pleneum at the top of the cabined with a screened outlet across the front. The GE power supply has vent holes in the bottom, which wound up being directly above the 1 foot square vent hole in the bottom of the cabinet, so as soon as the fan comes on, outside air is brought directly into and around the power supply. I plugged the entry hole in the other side of the cabinet with a piece of plywood, and the duplexer sits above it, so no outside air necessary there. It took a crane to get this cabinet installed on the concrete footers we poured, as it weighs about 1500 # with the equipment installed. There are a number of pictures of this installation if anyone is interested: http://sbarcnm.org/CamelotInstallThumbnails.html 73 - Jim W5ZIT --- Eric Lemmon [EMAIL PROTECTED] wrote: Barry, With all due respect, I think the appropriate response to your statement is: Not necessarily.

Anyways, I a downstate Chicago guy, I live in the farmfields 45 miles south of the city. While I will not argue that there are some alligator systems in the city...and suburbs Be careful of acousing any of those machines of being gluttons. I'm not sure which machines you had in mind, but probably the widest coverage 2m machine in the city is CFMC on 146.76. They have several reciever sites, and run modest power off one of the tallest buildings in the city- 45 miles away here at my qth running around mobile they are usually between 1/2 and full scale on an icom with a 5/8 nmo on the roof of the surburban. Of course I can access the system full quieting, so it's bretty balanced for the users in the greater metro area. Now- during a band opening I'm sure it can put out a good footprint. FYI- during an average opening in the morning or evining during the summer we can hear the downstate repeaters just fine as well. The corn fields don't stop much, the city is a different story. One of my uhf systems is in the cornfields south of the city, and it plays much farther to the south than it does to the north into the city. (omni antenna on top of a 300' tower) In comparason- one of the largest UHF systems in chicago, 16 recieve sites last I heard, is on one of the tallest buildings as well, and for the last few years has been running on exciter power (4-5 watts) that is being divided to three panel antennas (to put the footprint away from the lake), and on 1/3 or exciter power at that height from the panel antenna in any given direction it's very common to hear the output 70-80 miles away on a mobile with average conditions. Im sure on a good base 100+ miles is pretty easy, and during an opening, well, who knows. Does that make them a glutton? If you could put your antenna at 1300' AGL with a relativly short feed line, wouldn't you? There are issues in the metro areas city with building penetration, intermod general high levels of rf garbage, topography around the city with a few holes and river valleys where it can be hard to recieve the talkout from the city. Skipp covered the rest well in his response. If there are specific machines you notice, please contact me directly, I would like to know which ones. I have a pretty good knowledge, and know people who have more knowledge of many of the boxes here, maybe I could help research this for you.

Not! A properly-designed electrical distribution system does not need such pathetically inadequate gimmicks. As a power engineer for Boeing, I see many instances of our IT people being pressured to install surge suppressors where they are completely unnecessary. It is the responsibility of the utility to provide an AC power source that is appropriately protected with fuses and surge arrestors at the distribution level- usually 12kV or 22kV. Once inside the radio shack, each station should have a properly-grounded 120 VAC feed, along with appropriate protection of the antenna feedline. The highest priority should be to ensure that every conductor that enters each radio equipment cabinet has the *SAME* ground reference for protection. If you are converting the incoming AC to nominal 14 VDC floating on a battery, you should be okay. 73, Eric Lemmon WB6FLY As an adjunct we recently suffered a huge storm strike very close to the house (5 metres destroying a tree) , now I really don't know if the Belkin protector boards really worked or it was luck but most of the light bulbs expired but nothing connected to the Belkin boards did and some of the gear which was not died a bad death , comments ?

Using a battery on a power supply is that unless you run the power supply output at around 13.3 to 13.6 volts you are not properly floating the battery. 13.8 volts is too high for most batteries and it will eventually cook the battery. The other problem is, even at 13.8 volts, that is not high enough to properly recharge the battery after it has been discharged. It will never get back the proper charge at those voltages. To properly charge the charge voltage needs to be run up to around 14.3 volts. A 3 stage charger is required to do the job. Yes a couple of tenths of a volt does make a big difference in battery maintenance. 73 Gary K4FMX _ From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Don KA9QJG Sent: Thursday, May 24, 2007 12:25 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Re: UPS http://geo.yahoo.com/serv?s=97359714/grpId=104168/grpspId=1705063108/msgId= 72211/stime=1180018089/nc1=3848542/nc2=4025377/nc3=4609192 Tom I use a ASTRON RM 60M-BB (Battery Back Up} and a Optima Battery on My 440 Micor it switches Immediately when You get a Power Failure .

Re: [Repeater-Builder] Cisci LMR Gateway
It's entirely possible to boot the ios on a cheap computer via a usb stick , add a suitable interface /port card for radio control and you have all the advantages of the radio over ip in very cheap package , now if I can do it so can you guys :) although there are other o/s such as certain 'nix telephone devices that I would consider . From: Nate Duehr [EMAIL PROTECTED] Reply-To: Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Cisci LMR Gateway Date: Thu, 17 May 2007 19:15:06 -0600 (MDT) Anybody ever use one of these as part of a repeater system? http://www.cisco.com/application/pdf/en/us/guest/products/ps259/c1650/cdccont_0900aecd8034ef85.pdf Bill Nifty. Cisco came out with a real RoIP (Radio over IP) standard and published it with IETF about a year ago, and I was wondering when we'd start to see real products with the capability of doing it. Interesting. Sorry, haven't used one yet, but some thoughts... Advantages: - If you already have a Cisco IT shop, there's a good chance those folks can easily pick up on the changes in IOS commands (but probably need a half-day what's a radio doing hooked to my router?! session with the radio techs). - Standards based. Finally. Even if Cisco did have to go write the standard themselves. - Probably performs well. Cisco's boxes usually do a good job with the raw handling of IP, done right. Disadvantages: - None of those routers aren't cheap. ($$$) Add on the license for the RoIP gateway feature set ($995 list price... $$$), and you're getting into some serious money. - Never seen an IT product that can handle a lightning strike and keep running. At these prices, that's going to hurt - a lot. They need a low-end it's cheap enough that we can keep three spares product in this lineup. If you have a Cisco rep already -- tell them, make sure they send that feedback up the chain to engineering. Ask them to tell you how it'll survive hooked to a radio that is part of a site-ground/bonding system and whether or not it'll become the expensive ground lug for the radio when the tower takes a direct hit. Make 'em finish the engineering job, if they want to play in the radio world. - If you want service after the sale, you will have to buy a Cisco service contract ($). They're not going to be helpful like a smaller shop would be. It'll be an annual cost. ($/time). - Even though it's standards-based, I doubt anything else will talk to it on the IP side of things yet. Haven't seen anyone tackle writing an RoIP stack that matches Cisco's standard they published with IETF yet. Lots of devices out there claiming to do VoIP, none following any published standards or worse, purposely not following anything but proprietary standards, so you have to buy their radios and their VoIP gear together. This will slowly change... hopefully. When you talk to radio manufacturers, demand they look at the IETF RoIP spec. Put it in RFC's and scare 'em, even if you don't need to use it today. Ask 'em also why they're not coding to standards like H.323 which has been around in video-conferencing forever, all the way back to ISDN days. Get 'em to put in standard CODEC's like G.711 and G.729. Ask 'em where their standard SIP gateway support is. Etc. Etc. Etc. The radio world needs customers who understand VoIP already and can demand the radio-over-IP stuff at least matches the standards already in place. I'd be having a ball if I were working at a large government organization putting in all this digital/IP linked gear... and the vendor's worst nightmare. It'd be fun to be buying right now... -- Nate Duehr, WY0X _ Advertisement: Missy Higgins new album On A Clear Night stream full tracks now! http://ninemsn.com.au/share/redir/adTrack.asp?mode=clickclientID=781referral=hotmailtaglineMayURL=http://music.ninemsn.com.au/playlist.aspx?sectionid=2465sectionname=artistfeaturesubsectionid=9150subsectionname=missyhigginscategoryid=2577 Yahoo!

Dosnt make it right though I have several Jap TX here and all the units with uhf use other fittings. The UHF MASTR-II series comes with SO-239s, N was common on the 800 stuff. About the only time I have seen N seriously used is on duplexers and circulators. People can also use this cable on HF and VHF where PL-259s are common. To date I have never seen a 'clamp' style PL-259. I have one for Heliax, but that doesn't count. _ Advertisement: Your Future Starts Here. Dream it? Then be it!

From: Burt Lang [EMAIL PROTECTED] Reply-To: Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] LMR feedline revisited and revised! Date: Fri, 23 Mar 2007 01:12:41 -0400 Hi folks I have heard that the military will not allow BNCs on RF connections because the bayonet connection on the outside shell allows the ground side of the cable to vary (wiggle) and be noisy. BNCs appear to be used for data and low freq but TNCs are specified for RF use. Some years ago a local club was having trouble with their homebuilt duplexor that used BNC connectors on the cable connections. The duplexor became noisy intermittantly. Move the cables and it would quiet down for a few days but would always return. I suppled them with equivalent TNC connectors for the duplexor and they never had trouble again from that source. The standard PL259/SO239 combo has an impedance of approximately 35 ohms. If the insulation is removed from the SO239, the impedance is close to 50 ohms. I did see a Japanese wattmeter (I think it was Yaesu) that had insulatorless SO239s on it. One problem with the PL259 that I have not seen mentioned is that it is not weatherproof and the ground connection is problematic at best. It is very easy to tighten the shell and then find it loose because the teeth on the PL259 were not bottomed into the notches in the SO-239. Just my 2c for what it is worth. Burt VE2BMQ Eric Lemmon wrote: Allan, That's a good question! Both N and BNC connectors vary the dielectric thickness, and the spacing and diameter of the center and shield elements, so that the swept impedance seen by a Time-Domain Spectrometer (TDR Test Set) shows no variation in characteristic impedance through the connector. When a Constant-Impedance connector is installed CORRECTLY in a transmission line, its presence will not be revealed when swept with a TDR Test Set. The infamous PL-259 plug, when mated with the matching SO-239 jack, is far from constant impedance. Even the most basic TDR Test Set can detect the impedance bump where UHF connectors are used. Where the impedance is not constant, unwanted parasitic oscillations can occur, which means that intermodulation and spurious signals have a fertile breeding ground. Moreover, the ideal RF transmission system comprises cable and connectors that present a uniform 50-ohm impedance, without any significant bumps or dips. This cannot be achieved with RF connectors that do not have constant impedance. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of allan crites Sent: Thursday, March 22, 2007 7:57 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] LMR feedline revisited and revised!

Resonance has nothing to do with the amount of gain an antenna has. Resonance only means that capacitive and inductive reactance are equal.

The problem with 30 feet of wire will be getting power to it as the impedance is so low the loss in the matching network will be quite high.

When changing frequency there is a phase shift at the end of each element. That phase shift is cumulative and by the time it gets to the higher elements the phase shift can be significant. That destroys the pattern of the antenna and thus the gain. With a dipole antenna all the elements are fed from the same source so you don't have that same kind of phase shift from element to element and the pattern remains more intact with a shift in frequency. Yes there is some phase shift in the phasing/feed lines to the dipole elements that eventually disrupts the pattern of the antenna and thus the gain. But this type of antenna can be operated over a much wider range than a collinear type. Swr on the antenna only becomes a problem when it gets high enough that the transmitter can no longer be matched or it is excessive and caused excessive feed line loss. By using fatter elements it provides for a broader Swr and makes matching easier. Does any of this fit with your methodology? :) 73 Gary K4FMX Thanks for trying to teach how to suck eggs The dia of a radiator has to be incresed to a noticable portion of the wavelength in use to appreciably increas useable bandwidth , an excursion of 2%/Frq does produce a noticable drop in response and gain , just because the swr is acceptable does not the thing a decent radiator , I suggest you spend a day on a rabge some time and do some tests , when I have some time I will pursue it further but atm I have to finsih sorting out the next $ generation project.

RE: [Repeater-Builder] Effects of doubling RF output on UHF repeater?
Upping the power changes the balance , if you really need to fiddle with it improve the antenna for a boost both ways and at no additional running cost . From: Tony L. [EMAIL PROTECTED] Reply-To: Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Effects of doubling RF output on UHF repeater? Date: Mon, 05 Feb 2007 14:47:34 - One of our 70cm Amateur Radio repeaters is currently outputting 50 watts into the duplexer. We're considering replacing the existing RF power amp with a 100 watt model. Current draw on the 50 watt unit is 8 amps. The 100 watt unit will draw 20 amps. Our power supply is rated at 36 amps continuous, and the duplexer is rated at 250 watts. Half of our users believe that the repeater's output power is perfectly matched to its receiver. That is, users of high powered mobile radios generally lose repeater reception at about the same time the repeater's receiver loses them. However, the other half of our users believe doubling the repeater's power output would generate increased activity since the repeater could be heard more comfortably. We could upgrade without changing any of our other infrastructure. However, these questions arise: 1) Will the hundreds we pay to upgrade actually translate into significantly increased range? 2) Will we risk generating additional receiver noise by doubling our output power, thus losing coverage in the process? 3) Will using a higher power level shorten the life of other system components over time (e.g., power supply)? By the way, our frequency coordination would be valid even if we doubled our output power. _ Advertisement: 50% off on Xbox 360, PS and Nintendo Wii titles! http://www.play-asia.com/SOap-23-83-4lab-71-bn-49-en-84-k-40-extended.html
RE: [Repeater-Builder] Mastr II Station Power Supply Problem?
SO what happens when you connect a larger power supply ? From: Bill [EMAIL PROTECTED] Reply-To: Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Mastr II Station Power Supply Problem? Date: Sun, 04 Feb 2007 22:01:14 - I'm setting up a Mastr II VHF station for a 2 meter repeater and when I got to the power amp to check everything I can only get about 86 watts out of the 110watt PA. I noticed that the power supply starts to fold over at about 20 watts out and when I get to 80 watts the supply is only at around 8 to 9 volts. This Mastr II station has the PLL exciter but they gave me a 4 transistor power amp the original amp was missing. This is the newer type station with the IDA controller. I looked up the model number of the supply and it's a PL19D430272G1 Rev 4 which shows to be the right power supply for the station. I don't have my spectrum analyzer at the moment so I can't tell if the power amp is spurring although station metering shows below rated current on transmit. Any clues?

RE: [Repeater-Builder] Re: 6M cans made from other metals
A valid point however most anything that will accept a silver plate is usually aceptable , copper tube is excellent From: Eric Lemmon [EMAIL PROTECTED] Reply-To: Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Re: 6M cans made from other metals Date: Mon, 25 Dec 2006 17:36:58 -0800 Before we get too far into a discussion of what metals *can* be used to fabricate a duplexer, on 6m or on any other band, we should perhaps consider what metals *should* be used for that purpose. If we examine the basic differences between cheap duplexers that drift all over the place and become noisy in a short time, and expensive duplexers that are rock-stable and noise-free for years, we find that they boil down to just a few: Materials used in construction and workmanship. An ideal duplexer is made of materials with complementary coefficients of expansion, meaning that as the outside body of the cavity expands and contracts with temperature changes, the inner elements move in such a way that the tuning is not affected to any significant degree. Before you conclude that your duplexer doesn't need any fancy temperature compensation because it is in a temperature-controlled radio room, think again- ambient temperature is only part of the picture. Let's suppose that you have a 125 watt transmitter feeding a six-cavity duplexer that has a typical insertion loss of 2.2 dB. That power loss of 2.2 dB equates to about 50 watts that is consumed as heat in your duplexer, and you can bet that the duplexer components will start moving on long transmissions. If a poorly-made duplexer is subjected to constant cycles of heating and cooling, the contact surfaces will wear and sparking will occur since the movement is happening while transmit power is applied. High-quality duplexers have beryllium contact fingers working on a silver plating. The interior of the cavity may also be silver-plated to increase the efficiency due to skin effect. Cheap duplexers may have simple friction contacts made of copper or brass. So, yes, it is possible to make duplexers from almost any metal that can be brazed, welded, or soldered. However, combining diverse materials to make a duplexer that is effective, efficient, and stable can be a challenge. YMMV... 73, Eric Lemmon WB6FLY Yahoo!

Re: [Repeater-Builder] FYI: FCC officially issues RO dropping code requirement
It is now just a matter of time. The problems with hams not understanding what they are doing will increase. Interference will increase. Commercial interests will petition the FCC for the frequencies. The hams will not be able to defend their desire to keep the frequencies. Now the ham frequencies will be sold to the highest bidder. The handwriting is on the wall. Less that 10% of the newly licensed hams can draw a simple block diagram of the radio that they use. Just my opinion, based on my observations. 73 Glenn WB4UIV I don't think you have made real consideration of the truth at this point , you appear ill informed and insular because other countries have dropped code each time with great success and no theft of bandwidth , or somehow is your governing body more evil than ours ? perhaps there is a secrete plot ? I suggest you relax and accept it , in the long run it means more Amatuers and incidently it doesn't mean a decline in skills as you should acknowledge that arguement has been happinging for time in memorium .

Soiunds like the tool is a poor fit , I remember breaking several cores on a 520 years ago and had to makes a fatter tool to wind them to correct tune ( with some application of a soldering iron) From: Glenn Little WB4UIV [EMAIL PROTECTED] Reply-To: Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Subject: Re: FW: Read: [Repeater-Builder] Stuck cores Date: Fri, 08 Dec 2006 23:08:00 -0500 How fast are the cores moving that they require braking?

Ok so you had a bad unit , I have only built 4 so far but all worked well ... maybe the builder of your units didn't pay suffucuent attention and remember making cavities apart from some simple machinging is pretty easy .

Re: [Repeater-Builder] 6M duplexer wanted in UK
how do you mean thinking outside the circle ?. Have you contacted local firm which deal in such things ? commercial cabler perhaps ( not been in the uk for many years so unfamiliar( Ther must be someone who has a useful supply of suitable cable with in a decent distance ? I have been asking for many months in all of the appropriate forums etc, and apart from being ripped off by a chap in Ireland, nowt, zilch, nothing. I cant help there I have never had a problem sourcing it , the last rol came from a broadcast station about 200 k away for free. ( some scotch ) Unfortunately here in the UK a lot of people just are not interested. I don't really want to buy new as it costs a fortune here and if I could, would not even consider using it as it can be very troublesome, but as Dave UZN well knows a commercial duplexer will cost over £1000 which no radio amateur could really justify. how much new for the amount required ? perhaps temering need with wasted time makes it less $$ ? Good lucj with it 73 _ Advertisement: Meet Sexy Singles Today @ Lavalife - Click here http://a.ninemsn.com.au/b.aspx?URL=http%3A%2F%2Flavalife9%2Eninemsn%2Ecom%2Eau%2Fclickthru%2Fclickthru%2Eact%3Fid%3Dninemsn%26context%3Dan99%26locale%3Den%5FAU%26a%3D23769_t=754951090_r=endtext_lavalife_dec_meet_m=EXT Yahoo!

Re: [Repeater-Builder] 6m repeater for sale
Hi problem maybe people allready have a 6mtr rptr, like me, but need a resonably priced duplexer. I personaly can not justify paying around £1200 UK pounds for one... You are a ham . make oneand I am certain you can for considerably less than that ( I have several times) Yahoo!
