Re: [Repeater-Builder] Audio Reproduction
Hi Kevin, Since the final result of a PM modulator is FM, the term True FM implies that the modulator being spoken about is just that, truely FM, not PM. TheTrueoutput of a Truephase modulator is Trulypreemphasized audio. The Trueoutput of a Truefrequency modulator that is preceeded byTruepre-emphasis is also Truly preemphasized audio. But usingthe termTrue FM implies theremust also be a False FM, which wouldbe PM. So we can say that the True output of a False FM is Truly preemphasized audio. Likewise, there is no need for True preemphasis ahead of a False FM to obtain preemphasized audio. 73, Bob, WA9FBO Yahoo!

Re: [Repeater-Builder] SO-239 Shields
David, Save yourself a lot of time and effort, and simply use a high-quality crimp-on bulkhead connector. That eliminates the troublesome hood and the inevitable impedance bump. Such connectors are available in UHF, mini-UHF, BNC, TNC, and N connectors, to name a few. For extending the MICOR front-end preselector to the back of the unified chassis (the route of the original input cable) use RG-400 or RG-142 double-shielded coax, with a low-loss RCA plug on one end and a N female bulkhead connector on the other end. Even if your repeater is on 2m, the N connector is far better than UHF or BNC. 73, Eric Lemmon WB6FLY David Schornak wrote: Does anyone know where to get an SO-239 with a shield, or just a shield for an SO-239?...

This helps us to eliminate confusion about what type of modulator needs to be installed into a radio set that ultimately transmits FM in any event. The use of the term allows folks that aren't as radio inclined pick up on the fact there is a difference between FM and PM modulation, and eliminates the question "I thought it was an FM radio". You see, we (Repeater Builder) offer repeaters with both types of modulation schemes, and there need to be a way to differentiate between the two modulators without adding confusion to the whole matter. I'm sorry if you own into our way of thinking, but this was the best way of getting around a bad situation for folks that aren't as radio savvy and you and I (many of our customers), that I could come up with.

Hello Mike ... Mike Morris wrote: At 06:17 PM 4/5/04 -0500, you wrote: Looking for info on a UHF Consolette base. Which conversion to make the unit into a repeater? Thanks Jimmy Floyd NQ4U There were Motrac, Motran, Mocom 70, and Mitrek consolettes. The newer ones are called Desktracs and have either maxtracs or spectras in them. A consolette is not a high performance device. They were initially designed to allow marketing folk to sell a mobile radio at a base station price. Another way of thinking is that it offered the sales team a low cost base station. Note that the box is not big enough for a decent duplexer. 99% of the consolettes were used as base stations in non-public-safety environments like shopping malls, construction firms, etc. My comments below are based on UHF - the close spacing on 2m will make in-chassis duplexing a major headache. A number of years ago, I converted a UHF Consolette base station into a wire remotely controlled repeater. I believe it was a L44LHB (450-470 MHz) This was done at a customers request. He was happy and I never heard a complaint. The Motrac consolettes I have worked on have all been as base stations. The LHT series have an active front end and are a real pain to duplex. While the MHT series will duplex very nicely on UHF (they have a passive front end) I have had zero luck in getting any high band Motrac to duplex in the chassis without unacceptable desense. The heat rise while transmitting also leads me to believe that it won't be a practical table-top-repeater. The LHT receiver is spec'd at -60 dB IM rejection and has an active preamp in the front end. The MHT receiver is spec'd at -80 dB IM rejection and has as the first active device a FET mixer. The high IF also has a crystal filter. I agree with Mike's statement about the high-band Motrac duplex modification although I did duplex the high-band Motrac Consolette about 30 years ago to good performance as a base station in Amateur Service. The transmitter duty rating is about 20% transmit / 80% receive due to cooling problems of the transmitter and power supply. The high-band duplex Motrac Consolette base station is still in service here. I bought it as part of a fire sale in the early seventies for $50. I believe I also still have a UHF Motrac Consolette Base Station which is no longer in service - in case anyone is interested. I bought it from a guy named Wayne M. in Burbank, California for $50 about 30 years ago ... before Wayne discovered the 440 MHz band ... then he groaned. ;) The low power UHF Motrans will work intermittent duty. By low power, Mike means 15 watts output. The Mocom 70s I never played with much. I have tried duplexing a UHF Mocom-70 about 30 years ago or so, there is too much densense to allow good performance as a repeater. I have a number of Mocom-70's here in case someone has a question. BTW, am looking for a high-band Mocom-70 receive crystal on 161.10 MHz. I want to listen to the BNSF road channel. The low power UHF Mitreks will work - and a Mitrek radio can be fitted into a Mocom 70 consolette but with a very necessary electrical mod to the box... I found a high-band 110 Watt Mitrek Consolette Base station at a swapmeet 3-4 years ago for $25. It is now in my garage. If you are planning to use a Mitrek in a designed for Mocom-70 environment, please be careful. The Mocom-70 Audio output transformer secondary is grounded on one side of the winding. Not so with the Mitrek as both sides of the speaker audio are hot. The Mitrek Audio output is fed from a pair of push-pull IC's then fed through a pair of capacitors for DC decoupling. In the Consolette Station package, Motorola installed a 1:1 transformer to isolate the push-pull IC's from the chassis. The 1:1 transformer comes with the stock Mitrek Consolette Base Station chassis. Note that the Motran, Mocom 70 and Mitrek consolettes came with a couple of different power supply options. Watch out if you swap radio chassis... you can physically bolt a high power radio into a low power consolette chassis, but the radio will not be happy. Nor will the power supply. :( Note that the Motracs, Motrans, and Mocom70s are all over 20 years old, and some are over 30. If you want to do a table-top-base, I'd get a Mitrek model and convert that. It would be simpler. As I mentioned above, the UHF Mocom-70 doesn't take too well to duplexing. Look at the repeater-builder web site on the Mitrek page. The interfacing document I wrote has been used to build over thirty repeaters, and at least three were in consolette housings. Or get a Desktrac repeater and over half the work is done. Note that a Desktrac is a single radio chassis and a Desktrac repeater has two radio chassis inside. Any other questions? Mike I certainly

Re: [Repeater-Builder] Audio Reproduction
Hi Kevin, When we (Scott and I) go to build a repeater for someone or are talking about a radio set that has or needs an FM modulator, it gets referred to as true FM. This helps us to eliminate confusion about what type of modulator needs to be installed into a radio set that ultimately transmits FM in any event. Yup, I know what you're saying. The Handbook peoplemention 'direct FM' and 'indirect FM' as alternate terms, but I don't like those any better. But if I may critiqueyour last sentencefrom a strict definition standpoint (and here's another placewhere Bob goes over the edge): Yes,you caninstall either an FM or a PM modulator. Ifyou choose the FM,itmust be accompanied bya preemphasis circuit that coversthe entire voice audio spectrum. If you choose the PM, you won't needa preemphasis circuit. Such a system,by strict definition, is not an FM system, it's a PM system. If we had an FM system, we'dall be transmitting flat audio. Since wedon't transmit flat audio and we do transmitpreemphasized audio, an engineer outside of our circle would say we have a PM system. I can hear it coming: "Whoa!This here's a True FM transmitter, and no lilly-livered engineer is gonnatell me that this thing transmits anything but True FM!" Yes, but there's nothing wrong witha PM system. In fact, theredoesn't have to be a single PM modulator in the whole system - - it can consist of 100% FM modulators and still be a PM system. The whole definition rests on whether or not the audio is transmitted preemphasized. See where I'm coming from? I will readily admit thatavailable PM exciters can have all sorts of shortcomings. They distort when you ask for a lot of deviationat very low frequencies like CTCSS. There are inherent nonlinearities in the varactor tank circuit that create a littledistortion. Tuning the multipliers correctly is important for low distortion. Andwe've seen some sloppy engineering in the design of theaudio and limiter circuits. But if a guy wanted to, he could design one heck of a great PM exciter using, say, DSP, and it would work exactly aswell as any FM modulator. Has this topichas been bantered about for a long time? Yes! Will I change anyone's mind? No!Is it time I finished this and did some real work? Yes! Am I starting to sound like Donald Rumsfeldt? Heavens, yes! Have a great day! 73, Bob Yahoo!

RE: [Repeater-Builder] Thermostaticaly controlled fan cctt please ?
I went this road a few years ago using the small button thermal switches (Switch Craft - etc.) that are available in a variety of on-off temperatures settings, but it didn't prove overly successful. The small thermal switches have to be heat sinked to the PA, so you have to route AC for the fan up to some location on the PA heat sink, this is messy, not easy to implement, and requires extra AC (hum) wiring running around the station. The switches don't have an impressive life cycle and many started going intermittent and erratic in a year or so. The new approach I implemented is to use a solid state relay, they require nothing more than a logic level to drive them, which is easy to find about anywhere in the station or controller (most controllers have logic outputs that can be controlled by writing a simple macro command controlled by the PTT command). This isn't temp controlled, its time controlled, so fan comes on with PTT command from the controller, fan continues to run for 4 minutes after PTT drops. ( I use this control scheme for PA and general cabinet fan cooling operations on all my repeaters using SCOM 7K controllers) This has proven much more reliable over time than temp. control and you will likely find the fans can do many more on-off cycles during their usable life than the thermal switches. Solid state relays last a lifetime and cost less than the thermal snap disc switches in many cases. The fan starts PA cooling process w/o waiting for PA to heat up before cooling can start and then try and play catch up; a 3 to 4 minute post PTT run time on the fan is plenty of time to allow for more than sufficient cool down of any residual heat; this is where a thermal control switch can often cycle on-off several times depending on the proximity of the thermal switch-fan-main heat sources, and size/density of the heat sink. The power consumption of a good muffin fan is about 4 to 8 watts, so even if you have more run time using the timer approach it isn't going to amount to 20 cents of electricity a month and you end up with something from my experience which has proven much more reliable in the long run. A side benefit to having the fan come on with PTT other than PA cooling is it supplies immediate air movement inside the cabinet for some cooling to the power supply, circulators, etc. So hope this is some help or insight for your application - Good Luck Rob K7EI -Original Message- From: dave_g7uzn [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 06, 2004 9:02 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Thermostaticaly controlled fan cctt please ?

[Repeater-Builder] Ringos, Diamond, Comet Hustler Antennas
We are using Ringo Antennas for both Commercial and Amateur Applications right now, they work just fine for us. Have you ever measured the bandwidth of the Comet or Diamond Antennas? Most (of at least the Multiband) Antennas are quite narrow in bandwidth and don't make the entire 440-450 Amateur band with usable reflected power values. They are also not nearly as hardy in construction. The Hustler Dual Band antenna I measured a month ago would not be commercially usable for a repeater site. Like the Comet/Diamond Multiband the bandwidth was to small and non adjustable. The mono band Hustlers are quite nice, I've just installed a new pair to replace a high preformance commercial antenna array and they actually out preform the original Decibel commercial antenna system. The Hustler mono band Antennas are quite hardy, I don't have a problem installing them at commercial repeater sites. I no longer install most of the Comet and Diamond antennas, the high winds blow and shake them into failure mode within a few years. A large bird flew into one 1296 Comet I had up and broke it off at the base (never did find the bird...) If you live where the wind doesn't blow hard, they will probably hold up well for some years. The proof is in the overall preformance. Ringos remain good preformers for some of my commercial and Amateur applications. cheers skipp www.radiowrench.com Eric Harrison [EMAIL PROTECTED] wrote: Stay away from the Ringo's for Repeater use!

Re: [Repeater-Builder] Ringos, Diamond, Comet Hustler Antennas
I had tried Ringos in the past but they were unstable,the VSWR changed constantly and seemed to be affected by moisture. I also always had bad desense while duplexed on it. I switched to the Hustler G6-144 which worked very well for 25 years until it fell apart.My super stationmaster died after 15 years followed shortly by the harness on a DB dipole array. I am currently using a Diamond F23A monobander and it works as well as the G6 but doubt it will last 25 years. It has seen 3/4 ice with 80mph gusts. These are only my ham antennas,didnt count the 400-500 commercial antennas.
