Re: [Repeater-Builder] Amateur Mobiles as Repeaters, Part 13
Because we really had little experience in repeaters at the time (late 1970's), our club used a ICOM 22A for many years as the repeater receiver. We just poked around and found a signal that looked like it was useable to control the COR and used the front panel volume and squelch controls for the repeater audio and squelch levels. No one ever noticed we were using a mobile rig for over 15 years. It finally bit the dust after a lightening bolt (we theorized). But for many years, it was as sensitive as any thing I have seen. Not bothered by intermod, etc. Roger W5RD Texas Instruments ARC Murphy, Texas - Original Message - From: Cort Buffington To: Repeater-Builder@yahoogroups.com Sent: Monday, February 25, 2008 10:24 PM Subject: [Repeater-Builder] Amateur Mobiles as Repeaters, Part 13 Guys, We heard from Skipp that the Kenwood TM-271A is very much up to the task of repeater service.

Re: [Repeater-Builder] Re: Stupid Question about Db antennas.
Taking your idea a step further, it would be interesting how 3 real beams, fed with a power splitter, would work in this case. There was an article on this many, many years ago about mounting an array of vertically polarized mounted beams (5-6 element I think in pairs) each pair fired tangentially to a face off a very large tower. You had to construct a 6 way custom power splitter (low output impedance) out of copper tubing. I was thinking about maybe building one of these for the tower I have been on for years, a 25-35 ft. wide tower at the heights I have antennas at. But the overall complexity of the system was too much for the eventual system gain achieved I thought. You did get a somewhat omni pattern, although it had a number of ripples around the tower, but the average gain achieved was not the gain of the pair of beams or even of one beam , but less. I would imagine the coax loss contributed some to this, as the length between the pair of beams across this tower was substantial. Plus, there was all that hardware up there to maintain. We have existed for years using dB 224's for 2 meter and 220 just mounting the dipoles for an Omni pattern. The tower is so large that I would imagine that no matter what we did to the antenna pattern, the gain ripple would be large around the tower.

Just so we're singing from the same page, a few comments first. Pointing the dipoles all in one direction, for instance, increases the gain of a DB224 from 6dbd to 9dbd in the favored direction. And off the *back*, there is still a gain of 3dbd. It has a front-to-back ratio of 6db. Useful, but not really a beam. The -3db beamwidth of the front lobe of this beam is somewhere near 180 degrees. So the point is that aiming any one, or several, dipoles toward openings between buildings is probably not going to help huge amounts. Taking your idea a step further, it would be interesting how 3 real beams, fed with a power splitter, would work in this case. Back to the DB224 antennas, the RF lobe maximums aren't always in the direction that the dipoles are facing. As described by an engineer at DB Products, if you point 2 dipoles north, and the other 2 dipoles south, you will end up with a pattern favoring east and west with .75db more gain in those directions than the omni configuration. Must be because east and west both see all four dipoles... Fun, huh?

Re: [Repeater-Builder] Re: QRM on 220
Thanks for all of the comments (well most of them except one). I have run my 220 machines w/o P/L up until the recent past. Never had one that really wanted or needed PL, as in the late 70's when the first one came on, the 220 band was occupied in the DFW area by only a dozen or so repeaters. There are fewer now and only 2 or 3 that really are active (one is linked to a wide area linked repeater system, so it looks active but it is not really as a repeater). I have been on a tower for all these years that has had (or have) multiple high power pagers (VHF and UHF), high power High Band radios and then 800 and 900 MHZ stuff was added also along with a number of point to point microwave transceivers. Of course, our 2 meter, 220 and 440 have been there all along with a new 900 machine last year. You would think we would have heard stuff at this high of a perch, but rarely did I hear the 220 (before PL) kerchunk with a noise burst. I just thought it was strange that after the many years of monitoring the 224.18 output mobile, it is lately (6 months) that I have been hearing the signals on frequency. I have driven the same route for over 25 years to the job (BTW, yesterday was my last official day at TI/Raytheon after 41 years), so I had a pretty good record of listening on the band a few hours of the day most days of the week. It will be interesting when I find one what it is. I have one picked out that seems fairly strong and is in an area I can snoop around w/o/o being asked too many questions on what I am doing.

Roger W5RD If you are going to attempt to DF one of these signals, I suggest that you take a handheld (or two) and set it to the fundamental and a harmonic. Example: Here in Los Angeles the T-Hunting frequency is 146.565, and one of the games the hiders play is to camouflage the transmitter so on-foot hunting is an exercise in frustration. However by stetting an handheld to the third harmonic (439.695 MHz) I can walk up to within a few feet of the transmitter. With the radio inside a sealed box, with an attenuator I can get to within inches. Ever try and find a green-colored soda straw (with a 2m whip inside) in a wetlands preserve? At night, with no moon? So my suggestion is to use a 220 handheld to get close, and when it saturates to go to 440 or even higher (using a handheld scanner on 660, 880 or even 1300). I wouldn't be surprised to find it's a piece of computer equipment (like a router, print server, laser printer, etc). I say this because my desktop trashes a few 2m frequencies, and my Verizon-provided Actiontec GT704 router totally trashes GMRS frequencies. Interestingly my HP Laserjet 4 is clean.

Re: [Repeater-Builder] Getting On A Commercial Tower Site
Once you are at a site, go out of your way protecting not only your equipment but the other equipment at the site, since most likely they are commercial, high paying customers and they will not stand with freeloaders, as they call us hams, interfering with their professional equipment! Use bandpass filters, isolators, Heliax, professional antennas, etc. just good engineering practice will always help. Most likely during your time at the sight, you will come up against a customer finding out you pay little or no rent and want the same for their commercial equipment. After that, you could find yourself walking out the door overnight. I was a member of a system at a site for many years on top of the tallest building in town (a premier radio site still) and had very good relationship with the manager of the top floors. We were the first antenna up on the building, existing for many years with absolutely no problems, had insurance, used all the right equipment, and paid rent (albeit, $1 a year). Then, after a number of very successful years with zero problems, a management change must have occurred and, literally overnight, we were nicely asked to vacate. So, easy come, easy go. We left on good terms, but be aware that a situation like what happened to us could happen to you. It usually is a business decision and I could understand, but it is hard to take sometimes. My advice is just be as professional as you can be on what you equipment you install and make sure it is visibly as professional looking as the other equipment next to you. Sometime, your setup is better maintained than the commercial guys. I know ours was always and we were proud of the setup. It eventually outlived its original purpose and leaving the site was probably at the right time, just a little too soon for us who had lived with the maintenance day and night for many years. But, we enjoyed it, for sure, and the interface with our commercial benefactors (both building and TV) was great.

Also I have to keep a fan on the RF tray and station control because it gets to hot and when it TX it sounds like it has a open squelch.I am new to the repeater world. The repeater is working fine other then that. Thanks Bob kd7ikz echolink 216767 -- No virus found in this incoming message. Checked by AVG Free Edition.

Re: [Repeater-Builder] Re: 222 Mhz
Ditto here. My 13-509 never suffered any ills for over 20 years continuous repeater operation and it was an old original brown face model. No external BPF on front end, an 80 dB null set of duplexers with a 6 dB antenna on a tower that had 450 MHz, 800 MHz, 900 MHz and 150 MHz systems running 50 to 100 watts and pagers up to many 100's of watts on antennas just above the 220 antenna. Never heard a peep of Intermod. Never used PL. A 0.2 uV max. signal produced a noise free signal out of the receiver.

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 -- No virus found in this incoming message. Checked by AVG Free Edition.

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. It hears as good or better than our 2 meter repeater which was at the same level on the other side of the tower. No one ever complained of the 220's anemic power level. I picked up a 220 Maggiore fairly cheap a number of years ago and it performs about the same, albeit like others have said, the new Maggiore units are quite pricey.

They're expensive! I'd be much better off going with a repeater-builder conversion. Has anyone had experience with the older Midland 220 rigs converted to repeater operation? It looks like that may be a real inexpensive solution if I can find one and if they work well. -- Keith McQueen [EMAIL PROTECTED] 801-224-9460 On 11/6/07, Jim [EMAIL PROTECTED] wrote: Keith, KB7M wrote: I've built several repeaters over the years, but only for the 2m and 70cm bands. In a moment of insanity, I purchased a Wacom 222Mhz duplexer and now I realize that 222 Mhz radios suitable for repeater operation are not readily available. :-( I see that folks have documented methods for converting VHF high band MASTR II and Micor radios for 222 Mhz. Unfortunately, I don't have either radio in my stash of radios. I DO have some VHF Mitreks, some UHF Micors, and one VHF MASTR Executive II radio. Can any of these be converted to 222 Mhz? Does anyone have an already converted radio that they would be willing to trade for something? I know that the repeater-builder guys have already converted radios forsale, but I'd like to find a way to do it for less than the $700 that they want for them if I can. The ExecII should be pretty close to the MII, I would think. Don't spend good money on the made-for-ham boxes. First, they're more expensive then the RB conversions, and they WON'T work as well. I think I've heard of people converting Mitreks too, although like most, the PA's don't go. -- Jim Barbour WD8CHL -- No virus found in this incoming message. Checked by AVG Free Edition.

I have been thinking about a Hustler G6-144B but I am willing to trade a bit of gain for a more rugged antenna that will remain noise-free for a long time. One problem I face is that we have a limited mounting option on the grain elevator leg we are on so a lighter/smaller antenna is much preferable to a DB-224 style in our location. I can also get the FG1443 for about $150 which is quite attractive. http://www.antenex.com/c_search.asp?txtFunction=browse2selFamily=FIOtxtSubFamily=VHF+3+dB+GAIN+MODELS Thoughts? 73, de Nate -- Wireless | Amateur Radio Station N0NB | Successfully Microsoft Amateur radio exams; ham radio; Linux info @ | free since January 1998. http://www.qsl.net/n0nb/ | Debian, the choice of My Kawasaki KZ-650 SR @ | a GNU generation! http://www.networksplus.net/n0nb/ | http://www.debian.org
