[Repeater-Builder] want to trade 450 Vertex for a lo-band vertex
If any one is interested, I could use a 42-50 mhz vertex. Older ftl- 1011 is OK, 4 channels plenty. For swap I have a nice condition Vertex VX-2000 with bracket, mic, power cord in good shape. Would also consider a radius or maxtrac, as long as it's something I can program up on 52.525. thanks 7treez.. dave NA6DF Yahoo!

At 3/21/2005 05:50 PM, you wrote: Mike, Try placing a 3db attenuator in the receive line. If the result is the same or better, the duplexer needs tweaking. Since the duplexer was already retuned with no change in performance, I'd say it's not likely that it would need retuning if use of the pad yields better sensitivity. More likely that the front-end doesn't like the highly reactive load at the duplexer RX notch freq. is breaking into oscillation. My guess is that the receiver is not presenting a 50 ohm load to the duplexer. This would make the factory tuning off, as they are tuned with perfect 50 ohm loads. Not an uncommon problem. Yes, but that's more of a problem with the notches than the passes, since they're much narrower. Since the problem is being observed with the TX off no other signals present, notch accuracy isn't an issue here. Bob NO6B Yahoo!

Re: [Repeater-Builder] CSC cw ider's?
Dave, I have a CSC model CWID-50BR that came with a UHF Micor repeater I bought. I contacted CSC (Control Signal Corporation) at 800-521-2203, and had them burn me a new EPROM for about $30 as I recall. I also bought a manual for the unit, also for about $30. The CWID-50B is a versatile and reliable unit, and its only downside is that it doesn't have a smart AND polite ID function. I always run my IDs without PL tone, so that the users will not hear it. Like most polite IDers, the CWID-50 stops ID-ing if a user keys the repeater- but it doesn't start over after a short delay, it aborts. A small issue for me, and a non-issue for most Amateur Radio operators..

[Repeater-Builder] Re: 220 Mhz. repeater
Re: Maggiore 220 Receivers I'll second (or third that)... I just put another on the air. The only thing I don't like about most of these type receivers is how they offer up the local speaker audio as the input to the repeater controller. Many of these receivers simply dump audio to a resistive load and you get the added (small but still un-needed) distortion of the additional LM-380 audio power amp (which can be almost 8% at modest volume levels), which you really don't want or need in the repeater receiver recovered audio path. Some Hamtronics' layouts use the method of taking audio (across a resistor) after the af power amplifier IC. Here's where the flames start. Actually, the Spectrum Brand of Receivers have a really well done buffered low level audio section to obtain the recovered audio without the audio power amp distortion. I don't want to add a Micor Slow-Fast circuit, all I want is a clean working fast-close squelch circuit built into the original receiver circuit, which provides full bandwidth buffered , gated and de-emph audio. Spectrum at least does this one thing very well (although their customer service is another story) Hamtronics and Maggiore could do a lot to improve this function in their receivers, even though the supplied circuits do work very well. After buying the receiver, it doesn't make a lot of sense to need to purchase or build an additional squelch board circuit to rid yourself of the crash noise. Otherwise the discriminator circuit in the Maggiore is really very nice and has great audio recovery - performance.

Many of these receivers simply dump audio to a resistive load and you get the added (small but still un-needed) distortion of the additional LM-380 audio power amp (which can be almost 8% at modest volume levels), which you really don't want or need in the repeater receiver recovered audio path. Some Hamtronics' layouts use the method of taking audio (across a resistor) after the af power amplifier IC. Here's where the flames start. Actually, the Spectrum Brand of Receivers have a really well done buffered low level audio section to obtain the recovered audio without the audio power amp distortion. I don't want to add a Micor Slow-Fast circuit, all I want is a clean working fast-close squelch circuit built into the original receiver circuit, which provides full bandwidth buffered , gated and de-emph audio. Spectrum at least does this one thing very well (although their customer service is another story) Hamtronics and Maggiore could do a lot to improve this function in their receivers, even though the supplied circuits do work very well. After buying the receiver, it doesn't make a lot of sense to need to purchase or build an additional squelch board circuit to rid yourself of the crash noise. Otherwise the discriminator circuit in the Maggiore is really very nice and has great audio recovery - performance.

Re: [Repeater-Builder] Motorola QS R56
Tom, The R56 Manual is AKA Fixed Equipment Installation Instruction Manual and is available from Motorola Parts as Publication 6881089E50 for $85 plus a surcharge for end users. This is a large ring binder with many exhaustively-covered topics. While it is written primarily as a how-to manual for cellular telephone installations, it also addresses two-way radio sites. It covers such topics as site acquisition, handling neighbor resistance, environmental issues, political issues, easements, surveying, etc. All in all, it is an extremely valuable reference. One caveat: If you follow the electrical grounding instructions exactly per the R56 manual, an alert electrical inspector will fail the installation. The R56 team at Motorola is actively working this issue to avoid a conflict with the National Electrical Code. 73, Eric Lemmon WB6FLY Thomas Oliver wrote: Anyone know where I can get or download a copy of Motorola QS R56 Site standards?

Costs serious additional money. A good buffered audio circuit should be included into these type receiver circuits very often sold for repeater operation. Spectrum does this part pretty well, no need to go with the extra hardware/costs regarding this issue. Sometimes you have to use what you have or make/buy something to improve a circuit.

Re: [Repeater-Builder] M57719N RF power module
Brent, Typical RF power amplifier modules are most efficient and produce the least spurious output when operated at the rated output level. The M57719N is rated at 14 watts on a 12.5 VDC supply, over the 142-163 MHz range. When you start reducing the drive or lowering the supply voltage, you will very likely cause the module to become unstable and its efficiency will plummet. A case in point: My radio club has a packet node that uses a name-brand mobile transceiver on the 2m side of the system. In compliance with the Part 97 dictum to use the minimum power necessary for communications, we set the power level on the 2m radio to low, thinking that it would dissipate much less power at the lowest level, thereby allowing its duty cycle to be high. After operating flawlessly for several months, the PA module burned up. A replacement module cost about 80% of the cost of a new radio, but we felt it was worth repairing the radio. I installed the new module carefully and ensured that all drive parameters were correct. I also ran some tests to determine the efficiency of the module at each of its four drive levels. Surprise! It was most efficient at the highest (50 watts) power setting, and the module ran hotter at lower power levels- verified with an infrared thermal scanner. I confirmed the amount of heat being generated within the PA module versus the power being transferred to the antenna, by noting the current draw. This was not what I expected; I really thought that the input current would be more or less proportional to the output power setting, but that was not the case. The radio current draw at the 5 watt setting was about half of the current draw at the 50 watt setting. That means that the input power that didn't go the antenna was being wasted in the PA module, and it couldn't handle the heat. This looks like a fertile ground for experimentation. Moreover, it may not be prudent to use a 14 watt module when all you need is, say, 5 watts. If the 14 watt module does not lend itself to efficient power control, then it may be a good idea to install a 5 watt module. You might also contact Mitsubishi engineering for guidance on controlling the power of their products. 73, Eric Lemmon WB6FLY 73, Eric Lemmon WB6FLY Brent wrote: Anybody have any suggestions on varing the power on the M57719N Power Module?

[Repeater-Builder] Help with Deviation
Hello all Being fairly new to the radio world, I am hoping to get some info on deviation. I operate MASTR III stations in the 150 band for public safety. All of my freq's are currently licensed as wideband. I understand that the max deviation given these conditions is 5 kHz. I've been told to set my stations for 4.5 kHz just to be safe in case anyone is listening. However, when I set a new station up according to the manual, I end up with deviation around 3.75 kHz--using a 1 kHz test tone modulated at 3 kHz deviation, and a channel guard modulated at .75 kHz. Is this correct or should I be aiming for the 4.5 kHz level? It appears there are two adjustments in the MASTRUTIL program that effect this. The TX pot and the Repeater Gain pot. Not sure what the differences between the two are. Any basic information on this subject would be appreciated, or instructions on how to go about setting these levels to get max output in the MASTRIII would be great. Thanks! -Bryan Yahoo!

The antenna is a 4- bay on top of a water tower... probably 200' AGL, on the north end of Warner Robins. It seems more frequent in the morning hours (0700 or so), but is very intermittant. I believe it happens more during wet weather also, which leads us to believe that it has something to do with the telemetry transmitter at the water tower. (Our repeater is the only antenna on the tower. The telemetry antenna is on a telephone pole, about 25' high. It's a small vertically polarized yagi pointed directly over our repeater shack. I assume it's rather low power and transmits only when necessary. It's definately suspect, but we can't catch the thing burping when we're at the shack!) It's been going on intermittantly for about a year now. I don't think it initiates itself, but waits for an ID or for a user to activate the transmitter, then starts the cycle of kerchunking itself. Sometimes it stops in 3 or 4 cycles, but I've heard it go on for an hour or more. Of course, the whole place is surrounded by chain-link fence, so we've only got about a million metal-to-metal joins that might want to act like diodes at any given time! -- de WM4B Mike Kathleen, GA Mike; I'm not near as experieced as some of these guys but to me it sounds like the squelch may be just a tad on the loose side and the repeater may have some desense. WX will effect the squelch setting if it's set on the edge (at least here in MS it does). Your rptr may be detecting a very slight/weak signal from the user of another Rptr several miles away (you know how band conditions vary). Once the squelch opens the desense will kill the receiver until the coutesy tone and TX carrier drops out, then the recv'r opens right back up. This will cycle like this until the squelch closes back up (weak signal goes away). Try tightning your squelch just slightly, better yet check for any desense. I hope this makes some sense.

[Repeater-Builder] Kenwwod single band transcievers as remote (CONTROLLED) inputs
To overcome Jack Gerritsen and his constant jamming of our repeater I have placed two Kenwood radios on the hill. I interrupted my main UHF repeaters receiver to the controller with a C.A.T. RLS-1000 3 port mixer and placed the Kenwood radios on the other two ports. The Kenwood radios (TM-241 144MHz and TM-331 220MHz) are each splitting their discriminator audio out of the mic connectors on the radios into both a TP-3200 Tone panel and a RCL-MOT squelch module. The audio from the RLC-MOT feeds the RLS-1000 mixer and all works very well. The repeater users know that when Jack starts in with his [EMAIL PROTECTED] I can send a close command to the RLS-1000 to mute the audio coming from the UHF port and Jack is gone. Jack has been quit frustrated and so he scans around the bands now looking for our users on the inputs and finds them and starts back in on them again. Once the Kenwood radios have been compromised I have to make another trip to the hill and change the Kenwood radio frequencies. I want to do this remotely and I don't want to have to buy another Doug Hall RBI-1. I think I can use a serial output from my controller (a Linkcomm RLC-3) to a basic stamp and making the controller think it is commanding a RBI-1. My problem is that I don't know anything about how to communicate to the Kenwood radios. Obviously Doug Hall figured it out but he does not want to share this info with me. I don't blame him as he would rather sell me another RBI-1 and I don't have the patents or the equipment to try and decrypt the stream that he is sending from the RBI-1 to the radios. The folks from C.A.T. also figured it out and tried to put it into their CAT-700 repeater controller but found a big conflict with their implementation so the had to abandon it.

Re: [Repeater-Builder] Kenwwod single band transcievers as remote (CONTROLLED) inputs
Hi You might want to try an ICS Linker IIa, they are inexpensive, reliable and have remote base memory control. You enter the memory number you want on your DTMF pad and the radio goes there. The Linker IIa will remember the memory the radio is set to, even if the power fails. When port 2 is disabled the controller returns the radio to the 1st or home memory. The Linker IIa uses the 'down' on your mike input to select the memories. All the pl tones, offsets and other stuff is already stored in the radios memory and you can have the Linker IIa select from 1 to 250 memories. 73 Brian ka9pmm [EMAIL PROTECTED] wrote: To overcome Jack Gerritsen and his constant jamming of our repeater I have placed two Kenwood radios on the hill.

I have learned that the Kenwood radio is a typical single band radio with the mic plugged into it and it works accordingly but when the Kenwood RC-10 or RC-20 was plugged in the mic connector it supplied a voltage to pin 6 of the mic connector changing the function of the up/down pins in the mic connector to serial in/out.

Re: [Repeater-Builder] Kenwwod single band transcievers as remote (CONTROLLED) inputs
You could load up the 20 memory channels of each radios with your selection of frequencies and use the UP and DOWN pins on the 8-pin mic connector to cycle thru them. You just need to write a couple macros to pulse an output to either go up or down. -Sean On Thu, 24 Mar 2005 [EMAIL PROTECTED] wrote: To overcome Jack Gerritsen and his constant jamming of our repeater I have placed two Kenwood radios on the hill.
