Dear John, Thank you for the helpful feedback. I can be a bit pig-headed at times. I really wasn't sure exactly what deviation to set. I did monitor other repeaters and they are as wide as I mentioned. Having said that, I will adjust the deviation back to 5 KHz max if that is best practice. Michael Bloom, W7RAT Yahoo!

Re: [Repeater-Builder] Tin Sound Audio
most of them are using yeasu radios with stock mics that came with the radios. Just want to make the audio a little more to the base side rather than the tinny sound I get, but thought I would just play with it to see if it could be changed a little.

I then took that evidence, along with NIST tracable documentation for my service monitor to the next repeater coordination meeting.

The business license would be in the name of the family farm. I know that not everyone inmy family is interested in radio enough to become a ham, but would definitely own a radio if they could communicate reliably. Cell phones are horrible. I do not want to use GMRS frequencies for three reasons: I am not impressed with the policing of the GMRS frequencies. Anyone can get a GMRS radio, and the line between GMRS and FRS and CB seems to be very blurry. I don't want my mom to be the one listening when someone starts being rude on our frequency. Reason two is that I want to be able to hook up a phone patch. This is strictly forbidden in GMRS. Reason three is the "type acceptance" rule that prohibits several quality radios from being used in GMRS. My questions: What kind of cost am I looking at for a repeater pair license? Does each user need a separate license? cost per user? Can I do the research and find a frequency pair myself, or do I have to go through a coordinator? (if so, what does that cost?) (We live in a rural area, Thomasville, GA. Finding a pair should not be hard. I am hoping for a pair in the 460 band, as I have a very nice mastr II for that band.)

The fact that the two of us hold an extra class and the other an advanced class ham ticket was not explained but I assumed that it would be understood. That is not the problem, its the repeater intermod. This reply is the reason that I hate to post to a group such as this. Yahoo! Groups Links Yahoo!

Re: [Repeater-Builder] HELP: 2 meter repeater intermod problem from pager tr
The 'correct' maximum depends mostly on your neighbors when it comes to the ham band, but you should never run so much as to interfere with adjacent channels. If you are operating in a 15 kHz bandplan where the next adjacent channel above and below you is 15 kHz away, you should run not more than 4.5 kHz deviation (resulting in a 15 kHz bandwidth). That leaves no room for frequency error, but if you're on frequency, and your neighbors are, too, it will help minimize any problems. If you're in a 20 kHz spacing area, 6 kHz may work OK. You would have a bandwidth of 18 kHz. That would allow for up to 0.5 kHz of frequency error on both your part and that of your neighbors. Running 5 kHz deviation would give you both 1 kHz to play with for frequency error since your bandwidth would be only 16 kHz. If you're running UHF in Ohio, give it up - you only have 12.5 kHz to deal with. That means a technical maximum of 3.25 kHz deviation (12.5 kHz bandwidth). You may as well convert to SNFM (2.5 kHz deviation). That said, some receivers, particularly scanners, are now designed with much more narrow filters in them that will cut off at 17 kHz. That means listening to your system on one of those will sound choppy on voice peaks if you're running at 6 kHz deviation, or an 18 kHz bandwidth. So, sticking with 5 kHz is the best bet. It will retain compatibility with commercial specs (who are limited by law to 5 kHz maximum deviation for NBFM). Joe M. mbloom0947 wrote: Dear John, Thank you for the helpful feedback. I can be a bit pig-headed at times. I really wasn't sure exactly what deviation to set. I did monitor other repeaters and they are as wide as I mentioned.

Re: [Repeater-Builder] Digest Number 2865
It's not the 600 KHz that is the problem. The problem is that the paging transmitters are spaced the same as the TX/RX spacing on 2M, thus creating the possiblity of a third-order mix. Here is what is happening, mathematically: 146.94 + 152.24 - 152.84 = 146.34 When all the transmitters are on, all three signals are in the air at high levels around the site. Anything that can mix could be creating the intermod problem, from one of the amplifiers themselves, to a preamp or even a piece of baling wire tied to a fence post. The mixer doesn't have to be especially efficient, since it is so close to the affected RX, a few microwatts of re-rediated power may be sufficient. That is why this can occur even when everyone has BP filters and isolators and the transmitters look clean on a spectrum analyzer. So a 600 KHz filter would be of no use.

Re: [Repeater-Builder] Digest Number 2865
If it's mixing in the receiver or transmitter, notching one of the offending signals may help (such as a notch cavity on 152.240 or 152.840 MHz). Of course, it could be mixing in a number of other places, too. Joe M. Joe Montierth wrote: It's not the 600 KHz that is the problem. The problem is that the paging transmitters are spaced the same as the TX/RX spacing on 2M, thus creating the possiblity of a third-order mix. Here is what is happening, mathematically: 146.94 + 152.24 - 152.84 = 146.34 When all the transmitters are on, all three signals are in the air at high levels around the site. Anything that can mix could be creating the intermod problem, from one of the amplifiers themselves, to a preamp or even a piece of baling wire tied to a fence post. The mixer doesn't have to be especially efficient, since it is so close to the affected RX, a few microwatts of re-rediated power may be sufficient. That is why this can occur even when everyone has BP filters and isolators and the transmitters look clean on a spectrum analyzer. So a 600 KHz filter would be of no use.

Re: [Repeater-Builder] Non standard CTCSS tones in Amateur service
At 02:44 PM 12/21/04, you wrote: I know a repeater that required a tone not implemented in the standard 38 would not make a it too popular but is it legal? I was wondering if a pair of these on a rcv link would discorage interference. http://www.com-spec.com/ts64.htm There is no FCC rule specifying subaudible tones. Local coordination councils have been known to specify tones, usually what tone you can not use (i.e. the system 50 miles away on the same channel uses 100hz, they would appreciate it if you don't use 100hz). Nonstandard tones have been around since the late 1950s. I found 159.0 Hz reeds in a pair of HT-220s in the 1970s, and 121.1hz PL reeds in a pair of handhelds that came back from a job in Buenos Aires in the 1980s However, tones inbetween two standard tones are to be avoided due to false decodes... your inbetween tone can false two standard decoders, and either of the two tones that you are between can false you (there is a reason that there are 32 standard tones between 67hz and 204hz and not 35 or 40 - it's called separation between tones to minimize falsing). I commented on nonstandard tones for privacy in my writeup on the Mitrek reedless PL board, which is at http://www.repeater-builder.com/mitrek/mitrek-hln4181.html. One advantage to the HLN4181 - you can have a Mitrek on each end with NO tone element installed (i.e. set to 273.3hz) and they can talk to each other. The higher frequency tone also means minimum pickup delay. This is ideal on point-to-point links (and it saves having to make up any elements). Yes, the 273.3hz tone is harder to filter out than a lower frequency but it can be done with an active filter. The HLN-4181 PL board also allows you to pick weird or non- standard tones in 0.3hz steps from 273.3 on down, but to make them workable you need these PL boards on both ends... this trick can be handy on point-to-point links that you want to keep the riff-raff out of (if you don't mind the PL pick-up delay). Maybe 199.2 hz anybody? Or 235.0 hz? However, you have to remember that PL (or Digital PL) doesn't solve interference issues, it just covers them up. Sure, the RX won't unsquelch if it is requiring a weird tone and the idiot only has the standard tones but the idiot can still sit there and transmit on the channel causing a heterodyne or capturing / blocking the receiver, so what real security (or increase in usability) have you really gained? And what prevents a determined idiot from listening to you on the input with an OptoElectronics tone grabber and finding your weird magic tone ? (it only takes maybe 5 seconds of signal). And a used HLN4181 is around $20, a lot cheaper than a TS-64. Mike WA6ILQ Yahoo!

Re: [Repeater-Builder] Tin Sound Audio
Mat: You don't say how you are using the M-Pro Rx. The Vol/Sq Hi point is the best point to get audio from the Rx on older M-Pro Rx, if you have a plug in card shelf with a remote audio card in it, the 600 ohm line output is a better source of audio as it is already de-emphasized. If you are using a repeater controller, there should be some means to select de-emphasis on the audio input to it. If not or you are using some other method to interconnect your Rx/Tx, you'll probably have to build a de-emphasis network to go in the audio path. If you have a copy of the 600 ohm line driver card that mounts in the EP38 power supply in early M-Pro, there is a simple de-emphasis network on this circuit board that you could copy.

Re: [Repeater-Builder] Re: HELP: 2 meter repeater intermod problem from pager tr
What some repeater owners don't take into consideration is the accumulated effect of all audio going out on the transmitter. You may find that testing with a single tone, or maybe voice peaks, will give you a good reading. Voice+PL tone+the repeater voice ID can drive the deviation well beyond 5Khz or 6Khz on some repeaters. It's accumulative. A limiter really needs to be used, but some homebrew repeaters don't have this. 73, Joe, K1ike --- JOHN MACKEY [EMAIL PROTECTED] wrote: That should also be the max for a 20 Khz bandplan, to allow a little room for accidental overshoots. -- Original Message -- Received: Tue, 21 Dec 2004 11:38:25 PM CST From: mch [EMAIL PROTECTED] SNIP factual reasons) that 4.5 kHz should be the maximum in a 15 kHz bandplan.

The first place to look is to make sure all the TX's have isolators and BP cavities- one of the easiest places for mixes to occur is right in the PA. If you don't have an isolator and a BP filter, the energy from the other in band transmitters can come right in and mix there. Since the mix product is also in band it will flow back out to the antenna. The other place to look is the 2M RX. It needs to have plenty of rejection to the paging transmitters before the first active stage. A BP or BR filter may be required, as you point out. Joe __ Do you Yahoo!?

RE: [SPAM] - Re: [Repeater-Builder] Mastr II question - Email found in subject
Thanks much Doug. I figured as much. I think running the PA at half power should be safe then.

It will make full power and full sensitivity in 52/53 mhz, but I would de-rate the PA by a bit to protect it if it is going to be on a lot. I have not seen one which did not tune up on 6m just fine.. and I know of at least one which left the factory in the late 70's tuned on 6m... 52.525 as I recall on channel 2 repeater splits in others...

[Repeater-Builder] Question for the group... and a thank you.
One thing I could use some help on... Is there a software package that can turn a TIFF file into a PDF that can be cut and pasted from? eFax shows up as a TIFF format file, and nothing I have right now will take TIFF and make it into a file that I can cut and paste from. I've been offered a bunch of info that could appear up on repeater-builder, but my sources prefer to fax the stuff to me, and to quote my grandfather, who was a rural MD, you don't look a gift horse in the mouth. I have no interest in retyping everything. The OCR program that I have does not go a good job on the printed faxes I have (fax comes in at 200dpi). There is no rush on this as I'm going to be joining the family for Christmas and will essentially off-line for a week (the in-box will probably have a thousand messages to go through...). I may or may not be able to devote time to access email while away from home. Lastly, I'd like to thank all the members of this group for all the support over the last year. You all have been great.

Re: [Repeater-Builder] Mastr II question
Kevin; I would watch the voltage feed to the PA as just as important as the specific power level.. The GE power Supply idles high ~15v but drops into the lower 12.x volts under full load, you can watch it load down as you increase power. An Astron RS50 for instance may be set for 13.8v and at full power the station could make as much power as 150 watts. In this case backing down ( via only the power control) to 50 would potentially put the amp in an unstable region and make it potentially spurious... setting for 70-80 watts on 12.5 volts should yield a good combination... The main thing I am pointing out, which did not pup up in prior discussion of Astron vs GE supply is Astrons in general are higher voltage to start, at rated power draw, and the foldback design of the GE supply reduces itself based on load. GE supplies become self limiting in the power dept. A higher input voltage requires a lower power control setting to achieve only rated power, which in general means a lower ( read more flaky, as well as more difficult to hold stable) region of the pot, which restricts gain of earlier amplifier stages of the amp, but not later high current ones.. This is the scenario that makes for spurious output... Older 70's series PA's suffered from this and consequently most suggested power reduced settings spec'ed for MII at that time only called for max power de-rate of about 50% at 12.5-12.8 delivered to the PA...First generation VHF 110w amps were notorious for this when run at 13.8v, and low power settings. Running the PA on the lower end of 12v ( which is better/easier for battery backup purposes anyhow) seems to be a best plan to start with, and then a slightly reduced power setting should stay in the upper half of the power control pot settings... yielding 70-80 watts and stable Just my 2 cents Doug KB8GVQ At 11:07 AM 12/22/2004, you wrote: Thanks much Doug.

Re: [Repeater-Builder] Re: HELP: 2 meter repeater intermod problem from pager tr
Very true. I always inject my repeat audio right back into the mic circuit so it will have a limiter stage.

Voice+PL tone+the repeater voice ID can drive the deviation well beyond 5Khz or 6Khz on some repeaters. It's accumulative.

I believe you may still be thinking of the original experimental equipment used for proof of concept. The 2m cavity is a Sinclair 10 diameter unit. As for the deviation I have measured it with a Motorola Model 2600 service monitor at 6 KHz, about the same as other repeaters in this area. Just curious as to why you ( the other repeaters in your area for that matter) run more than the almost universally-accepted NBFM standard of 5 kHz peak deviation? At 6 kHz, I think even 20 kHz channel spacing begins to experience adjacent-channel interference.

Unless you're feeding your TX audio directly to an FM modulator (leaving the audio pre-emphasized through the controller), you'll want to de-emphasize it by adding a 10 K resistor in series 0.47 uF capacitor to ground after the resistor. Your audio level will drop after this mod. so you'll need to crank up the RX input level at your controller to compensate. Your controller may also have jumper or switch settings to do the de-emphasis there instead, so check into that as well. Bob NO6B Yahoo!

Re: [Repeater-Builder] Tin Sound Audio
Thanks Bob, will try this and see if there is any changes. The audio on the repeater actually seems fine to me, with the exception of a few folks, and they have used other radio's, and about the same quality, but in person there voice sounds nothing like they do on the repeater. Will see how it works.

That's the right place. I believe that audio is pre-emphasized. Unless you're feeding your TX audio directly to an FM modulator (leaving the audio pre-emphasized through the controller), you'll want to de-emphasize it by adding a 10 K resistor in series 0.47 uF capacitor to ground after the resistor. Your audio level will drop after this mod. so you'll need to crank up the RX input level at your controller to compensate. Your controller may also have jumper or switch settings to do the de-emphasis there instead, so check into that as well. Bob NO6B Yahoo! Groups Links Yahoo!

Re: [Repeater-Builder] HELP: 2 meter repeater intermod problem from pager transmitters
At 12/20/2004 08:35 PM, you wrote: We have 146.04/.64 repeater on a nearby mountain top. It worked great for years with a range of 100 miles or more. Since the phone company and a pager company installed their high power transmitters near the site of the repeater (within 100 yards) the repeater is virtually useless. After much head scratching I believe that the difference in frequency of the pager transmitter of 600 khz is the problem but have no idea how to solve the problem without going to an odd split. The repeater coordinator for this area of Virginia won't even consider that as an option. The equipment that we are using is excellent. The transmitter and receiver on the repeater are both Motorola Micor and were modified with to the repeater frequencies by FCC 1st class licensed hams using Motorola parts. This is not an equipment problem. We are running a set of Wacom cavities which were bought new and are correctly tuned and the antenna is a Phelps-Dodge Stationmaster. When the intermod occurs it is dependant on BOTH pagers transmitting at the same time. If only one pager is transmitting there is no problem. This may at first sound unusual but the pagers are in the 150 mhz band and they are exactly 600 kc apart. These transmitter are both 250 watts or more output. I've dealt with similar problems involving two VHF HB TXs that were 5 MHz apart. They mixed with every 5 MHz split UHF repeater at the site to convert the output to input (A+B-C mix). At first one of the VHF TXs was in another building a few hundred feet away, at that time the interference was just a few dB above the noise floor only present after long periods of dry weather. But then that TX moved into the same building as the other VHF TX our repeaters. That caused it to be present all the time much stronger. I tried DFing the actual source of the interfering signal(s). Sometimes they came from a tower joint, other times it was from an air conditioning unit, then another spot on the tower a minute later. It just came from everywhere. The site manager tried painting all the suspect tower joints (which had no signs of rust or corrosion - this was a fairly new tower) with some sort of metallic paint. This more or less cured the problem for about 2 months, then it came back until it rained or the joints were painted again. The problem finally went away when one of the TXs (a 25 watt paging TX) went off the air. Bottom line is that short of getting one of the TXs involved in the mix to move, there is no good solution. Remoting your TX to another location is probably the best bet. You can always run more power if the alternate location offers less coverage, but you can't make up the difference in RX if you put your RX there instead. After much head scratching I believe that the difference in frequency of the pager transmitter of 600 khz is the problem but have no idea how to solve the problem without going to an odd split. The repeater coordinator for this area of Virginia won't even consider that as an option. An odd-split will solve the problem but should only be a last resort, as opposed to going off the air completely. Among other disadvantages, it makes your repeater harder to find by travelers not familiar with your bandplan. Your coordinator may resist the idea, particularly if there are no odd-split repeater pairs currently in your bandplan. However, it's up to the coordinator to accomodate you the best they can given their current activity levels, channel loading your own technical constraints. Refusing to consider odd-splits on the basis of we don't have any don't want them or they're not in the ARRL bandplan is not a valid reason. Bob NO6B Yahoo!

Simply follow my suggestion in my last post and route Pin 701 to pin 1 of the port you're using for the Micor. Then program the Encode Control Line to be Active High (command *1021 1) and program your timer for the amount of time you want encode active during the tail (command *1007xx).

Re: [Repeater-Builder] Amateur P25 repeater on the air
Jim B. wrote: By way of PWF: http://www.k6ccc.org/k6ccc-r.html Neat Jim. I've been playing around with P-25 via a borrowed radio. Very interesting stuff. On this repeater: http://www.rmrl.org/rmrl_news/rmrl_goes_digital.htm Your web page mentioned still debating about analog ID's? Why? Your web page also doesn't mention if your users are typically monitoring a particular talk group? The group above uses $. Locally here anyway, we're ID'ing in digital, can't see any reason to change emission type to ID -- if someone were monitoring, they'd have to change receiver types too, which seems counter-productive. P-25 is an open standard, anyone that needs to copy the ID certainly can. (i.e. FCC) Hams can't run with the encryption features enabled, either, of course. The repeater also ID's via MCW over the digital channel when someone's using it in digital mode, which sounds really odd, but is copyable. (GRIN) Kinda like a CW operator with a generator that can't quite keep up with his amp. Heh. The repeater above turns off CTCSS when transmitting in digital mode, but some local users still run without CTCSS decode on analog, so there have been some questions once in a while about what's that horrible white noise blasting the repeater at 45 minutes after the hour?!. Heh heh. Yes Virginia, that would be the digital ID going by... The most interesting aspect of digital so far is of course that static simply doesn't exist. Instead your ear becomes tuned to what the vocoder does when it's erroring... Sometimes the Max Headroom effect... repeated syllables. Sometimes the audio gets raspy as the vocoder struggles to replace lost bits. But no noise per-se. You can get pretty good at it and tell when someone's starting to get marginal, from my limited playing with it, if you know they're headed out of range of the system. If you DON'T know they're headed into a dead spot they'll just be gone... bye... heh. On the flip side, the S/N gains of digital are real -- places where the system is 50-60% or more white noise, the digital sounds fine with a few digital artifacts. In my office at work where I'm surrounded by PC's that throw RF hash, analog copy on just about any local repeater is horrible... the digital systems sound perfect. Interesting stuff. Still expensive but coming down in price rapidly. Rumor is that Motorola will be to the $400 price range on the HT's by next year-end perhaps? We'll see. The closed IMBE CODEC in P-25 is the hobbling issue for REAL experimentation, unfortunately. There *ARE* smart enough people in the ham community to hack on DSP code these days -- but it'd be worthless without the source for the CODEC. Mm... Digital Toys! Nate WY0X Yahoo!
