Re: [Repeater-Builder] 450-460mhz Repeater Co-Channel Interference
Its called adjacent channel rejection, if your unit is not properly aligned this can occur. PL or not if its poor on rejection then you get bleed over, the same kind of thing that happens when a trucker goes by pushing excessive wattage from his CB and bleeds all over a poorly shielded amplifier or TV. This can also be a result of the shielding of your feed line to your repeater being compromised. These symptoms also cause desense on the receiver.

RE: [Repeater-Builder] Re: 900mhz , DTR, 906 to 923.75 MHz FHSS
That is correct. No external antennas and no amps are allowed by FCC rules. These radios are operating in a 902 ham/Scientific band so you can expect that operations will be noticed by amateurs on the band even if they are FHSS if you are running any significant power. They are allowed on a shared basis and must not create any interference, as well as must accept any interference from authorized users of the band. In many areas of the US the 902 ham band is becoming more popular lately with many repeaters being constructed. (eg. MA and CA due to the 440 band being destroyed by the PavePaws fiasco) Just something to consider.

[Repeater-Builder] Cable lengths - critical?
Hi guys. We finally secured a brck type UHF amp for our hamtronics machine. The Hamtronics puts out 7 watts after all the filtering into my Bird Termaline wattmeter. This needs to be knocked down to below 4 watts so as to not over drive the outboard amp. I had 2 options - one is to insert a pass-can into the TX line before the new amp. I have one at home. Tuned it to the correct frequency and it has an insertion loss of about 3db or so. The other suggestion from Hamtronics is to drop the V+ to the internal PA of the repeater to 11 volts or so (I can insert 3 or 4 diodes in series with the V+ to the PA to do this). But , in any case, we will need to make 2 patch cords. Is the length critical (i.e. electrical 1/4 wave or odd multiple thereof) work or will any convenienient short length work? We have some 9913 for this. Also, the way the repeater is configured right now, at the TX port of the repeater (before the filtering) there is a circulator. Should the circulator now be installed after the outboard amp? Or leave it where it is? Thanks. Ian VA2IR VE2RMP Repeater Group

Re: [Repeater-Builder] Micor RX IF filters

It appears that whoever crystalled that radio took the easy way out, and did not install a narrow-band IF filter kit. To the best of my knowledge, Motorola did not offer such a kit for the Micor, although several aftermarket companies and crystal houses did produce such kits for the Micor and for other radios of that vintage. Communication Specialists offers a Micor narrow-band kit, even today: www.com-spec.com/narrow.htm 73, Eric Lemmon WB6FLY They not only would not have needed the narrowband filters at the time, they actually probably would have caused problems. Even just a few years ago, the 12.5 splinter channels were in a 'low-power industrial' sub-service, and was normal bandwidth. Problem here is that a Micor would not have been legal, since the power limit for LPI channels was 2W. (I have an LPI Maxar-80 I use for a GMRS control station.) There probably were some other means of licensing the splinters that didn't have the power restriction. I know there were also geographic restrictions.

If someone else on the channel is using the same tone, you will hear them. (And as someone mentioned, some decoders are better at rejecting adjacent tones then others.) If there is someone on the same tone, and they were there first, your only option is to change tones. I'm assuming you're on a commercial system (hence the 450-460 in the subject!) Frequency sharing is the norm there, and if there is someone else on the same frequency as you, you just have to learn to share. If it's a community repeater with several tones turned on, you'll just have to turn that tone off, and maybe pick another if there's a user there, and reprogram their radios.

Re: [Repeater-Builder] Re: 900mhz , DTR, 906 to 923.75 MHz FHSS
It seems under Part 97 rules we could do this!!! Correct!! As long as you run your callsign as the SSID and are within 902 to 928, you can run all the power you want. (up to 1.5kW) A few things to keep in mind: 1. Good amateur practice still applies. (don't run 1.5kW, even though you *CAN*) 2. Your bandwidth is 20MHz wide. Realize that this wipes out a significant part of the band. I.E. 928-902 = 26 MHz of usable band - that only leaves 6MHz of the band left for someone else. Most devices can employ bandwidth limiting. This is sometimes referred to as cloaking or some other name. By doing this, your throughput goes down, but you are helping your fellow hams by only using 5 or 10 MHz instead of the whole available band.

There were certain regs pertaining to the use of the FHSS radios on 902. You would need to check into the FCC rules re. that. I understand your point that the antenna and amp limitations pertain to the unlicensed use of these low power FHSS units, we agree there. But there are also specific regs and limitations for ham use of FHSS which would come into play for amateur use.

The repeater itself has good audio, the more important question is the user's radios. Are they on frequency? Are the users shouting into the microphone? Is the microphone and speaker operating properly? I ask this because years ago I took care of some radios in a cement plant and the speaker-mics would fill up with cement dust. Then the warm breath of the users would create moisture in the microphones. We ended up having to waterproof the new speaker-mics before we gave them to the workers.. - In general, is it a good repeater? It's Kenwood's oldest low end unit. The TKR-720 and it's UHF brother TKR-820 were discontinued around October/November 2004. Kenwood not longer supports them with parts. Yes, some dealers still have some items on the shelves, but finding the part you need depends on how well the universe likes you that day The TKR-720 is a highband repeater that does 15 watts at 100% duty cycle, and 50 watts at 50%. Power is set by an internal manual adjustment. Personally, I think the 50 watts is optimistic. There just isn't that much heat sink. I'd use an external fan on anything over 10% duty cycle.. - Can it be easily tuned down to amateur frequencies? The following comments are based on the fact that the USA amateur band is from 144-148 MHz, and most repeaters are in 146-148. I do not know what the amateur radio repeater frequencies are in Cyprus where you are. The TKR-750K1 version is for 146-174 MHz, while the TKR-750K2 version is for 136-150 MHz. These are RF hardware design limits, the K1 version does not perform well in the 144-146 MHz portion of the 2m band and cannot be stretched. You have to buy the version you need. I have seen an early production unit that did not have the K1 or K2 on the label and was a K1 series internally. Once you have the proper range unit then the programming and tuning is very by the book. And the books are on www.repeater-builder.com - How can it be programmed? Do we need special software? Programming is done by either a KPT-20 programming box or by an the KPT-50 hardware programmer and the matching software. There are people on the mailing list that have the programmer. You can mail them the memory chip and the frequencies you need and they can mail you back the programmed chip. If you trust the timeout timer in your external controller you can have the timeout parameter in the chip programmed as disabled. The K1 version repeater takes the KPG-66D software. The late-model K2 repeater takes KPG-91D software. The software does not interchange between repeater models / versions. The internal controller is very basic, and in most amateur radio applications you will want to use an external controller.

Re: [Repeater-Builder] info on Kenwood TKR-720
The comments already posted are good. Our unit has required final transistor replacement several times over the last eight years. They aren't cheap. We found it necessary to silver-solder the device because heat, at 45 watts on a busy repeater, melted standard 60-40 rosin core solder. RF Parts' price for the final is $68, much cheaper than the others we found. Len Revelle N9IJ [EMAIL PROTECTED]
[Repeater-Builder] Re: Good Repeaters for UHF Ham Band
I've had experience with both as when we installed our 444.825 repeater we used an ICOM FR-4000. It was set at 8w out to drive a PA at 90w. It had great receive sensitivity with a pre-amp at 449.825 MHz. the only other transmitters at this site are 800 900 MHz, so no pre-selector is used...yet. We replaced the FR-4000 with a Kenwood 850 only because after 3 people trying for an entire saturday afternoon, we couldn't get the FR-4000 to play with an SCOM 7K controller. We had to use a CAT-250. We wanted to use the SCOM due to some particular features, so the decision was made to replace the repeater with a Kenwood 850. I still have the FR-4000 repeater which was purchased new for about $1300. If anyone is interested in purchasing it, we might let it go since it has been sitting in its original box for the last 6-10 months. If interested, email me off list at derekjmu at yahoo dot com. The CAT-250 controller is also available. Both are good repeaters. I prefer the Kenwood for simplicity, but the ICOM is a solid machine and with 50w out may not require an external PA in some applications. Just don't plan to use a SCOM controller with it. KD4ADL ---

Camilo, If you are not able to figure out how to wire the speaker cable, you can purchase the cable 0185180U01 from Motorola Parts for about $16. The cable includes a jumper to route the audio from the speaker's built-in amplifier back into the connector for feeding the speaker. Be careful not to miswire the speaker, lest the fuse on the backplane blow. The factory cable is worth having, because the jumper loop is a handy place to connect the SINAD input of a service monitor for front-end or preselector tuning and sensitivity checks. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Camilo So Sent: Monday, November 24, 2008 8:54 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] MTR 2000 I am trying to figure out the B+ 12 volts input and the audio from the MTR2000 going to the HSN1000 speaker input pin (number of the speaker) find one on my Junk with out the cable, hope to use it on my MTR2000 repeater.

I am leaving the controller in the Mastr IIe active so that its port can be turned off in the NHRC5 and become a stand alone repeater when needed. No bells and whistles in its controller but it takes care of pl decode/encode, short tail and auto cw IDer. When it is slaved to the NHRC5 and its UHF repeater all the IDs, and courtesy tones will be going out with the pl encoder active as it currently stands. What I want to do is to control the MastrIIe pl encoder so that it follows the UHF repeaters PL decoder when they are slaved together. Figured out how to cause the PL encoder of the UHF repeater to follow the pl decoder of both radios when connected together easily enough. So where to tie logic in to control the encoder in the Mastr IIe? On the backplane P3 pins B6 and C12 look promising but so far no luck. Perhaps I am missing something in the programming of the Mastr IIe controller? I can turn the CG encode on and off in the programming for the local PTT options, just have not found what pin to control for turning the local PTT CG encoder on/off. The reason behind all this is so that we can run tone squelch and never hear any house keeping signaling, ie, IRLP and echolink connections stay devoid of long key ups, noise, etc.. Oh, did it mention that it is a MastrIIe? :-) Thanks for any help on this, hopefully sooner then later as I am racing the snow level to get this project up in its home before its snowed in. -Dave, KB7SVP
