As crummy as cheap WX receivers seem to be, it seems hard to believe that 2 watts, 20 feet away from a radio that is more than 10 megs away, is the culprit. Are you sure it's not a case of the 2 watt radio being in close enough proximity to the WX radio itself so as to simply be blocking it? Ya know.. plastic case and all?

Re: [Repeater-Builder] Desense
Don, It's a coincidence that I am adding a WX-1000 weather receiver/alarm system to one of my 2m repeaters, and I found that the 2m signal was clobbering the WX unit. Even moving the WX receive antenna away from and behind (it's directional) the 2m antenna didn't help. The solution was to connect a small Sinclair preselector in front of the WX receiver. These little gems are about five inches square, and have four helical resonators. I tuned it to the WX frequency, and eliminated the 2m interference. Preselectors are not cheap, but DCI will make you a nifty filter, similar to the ones for 2m, that passes just the NWS frequencies. It'll cost about $100, since it's a custom model. 73, Eric Lemmon WB6FLY Don wrote: I have a lot of Non Ham friends who use the Mur Freq 151.820 taking their HT To Little League Games Camping Etc , And I was going to set up a Legal 2 Watt Narrow/band FCC type accepted Radio , Whew had to get that out of the way first.

Re: [Repeater-Builder] Sharing a receive site
Should work fine. I have a site that has receivers for my repeater on 146.085 and, 146.04, 147.735, 147.870, and147.930 Mhz as well. They are all using the same antenna that feeds a multi-coupler that feeds each receiver. The multi-coupler makes up for the loss that would otherwise be there due to adding all of the extra receivers. All use links to the respective TX sites. Linking is either in the 220 or 440 bands. There are no 2 meter transmitters at the site other than a frequency agile remote base (2 watts). The site has Amateur repeaters on 927.5375, 444.200, 224.320, 1292.200 Mhz (each duplexed) and a comercial 5 channel trunked system. There are also remote base transceivers on 440, 220, and 1.2 Ghz.

Re: [Repeater-Builder] Sharing a receive site
Bob, This is an easy one! Since we are now dealing only with receivers, the issue is merely how to feed two receivers their respective signals without any degradation from the original condition. This calls for a classic application of a receiver multicoupler. Ideally, the input signal is fed through a bandpass filter that allows only the desired frequencies to pass. A low-noise amplifier boosts the signal level and delivers it to a splitter which provides a 50 ohm match to each connected receiver while isolating them from each other. The key goal is to have the same, or a little higher, signal level to the original receiver as it had before the addition. Please don't be tempted to use a simple tee connector to split the signals. While this may work just fine, there are gremlins poised to complicate your life with mismatches, intermodulation, and other nasty things, so don't cheap out at this point! Trust me, any action that lowers the bar now will return, big time, to haunt you in the future. Use double-shielded coax everywhere, and avoid the use of barrel connectors or adaptors. This is not a big task, but you must insist on the application of good engineering practices. Don't forget to use low power and circulators, if necessary, to ensure that your UHF link radios don't interfere with each other. 73, Eric Lemmon WB6FLY [EMAIL PROTECTED] wrote: Hi, all -- I am on the technical committee of an amateur repeater club.

This is the Mastr Pro, right? If so, you MAY need a minor mod to be done in the driver stage of simply replacing a resister with one of slightly lower value.

Re: [Repeater-Builder] buillding a repeater
You should see about 350-500 milliwatts going to the pa deck and the bias/control line must be connected properly to the station frame. Many times I see these stations for sale at hamfests with the jumper wire allowing the pa to run only full-tilt-boogey, which is why they crash and burn so often - the control circuit is there to help cut back or turn off the power when the swr gets bad from someone stepping on your feedline or the antenna falling away entirely from wind or who-knows-what. If I remember correctly the bias line is blue 18AWG wire, sample there in parallel to ground and switch to some 75 ohm feedline to the dummy load - the voltage has to change or the pa will burn up at the site. It is really helpful if you have manuals but as you may notice I do more with sample and trial then draw the schematic and continue troubleshooting along the path of suspicion, slow but very informative.

Most of the caps need to be increased slightly and the two blocks which are bandpass filters will need to be changed or modded to allow the full potential to reach the phase detector located next to the output port, make sure you have a 80-110 watt phase detector board in place before you hike to the repeater site and connect. w9mwq wrote: I have a Micor TLD1693 amp, designed for the 150 to 162 Mhz range, and am told that the amp will not operate at the 146 Mhz range, told that componets have to be changed. Here is what I don't understand about it, maybe someone can help expain it. Into a Cushman serive monitor, I'm getting 100 Watts out of the amp at both 146.925 and 154.115 Mhz, keyed down the temperature is the same after a 5 min keyup test, allowed to cool down for each test. I see no spikes or spurs at either frequency. Granted this will be used on a repeater and key down times can go much longer, but why would this amp not operate at 2 meters, just cause Motorola says the specs are for 150 to 162. I've seen amps go from 138 to 174 with no problems, just a matter of tweaking. So help me to understand what the difference really is between the TLD1693 and the TLD1692 amps. Thanks. Mathew Yahoo!

[Repeater-Builder] Amplifier Question
Anyone have the specs available on a Decibel A40140MC-H amplifier? Input power/output power/freq range, etc? I have acquired one and would like to know if it can be used in the ham bands. It is also labeled Trilectric on it, with the model number A40140H. It looks like they are the actual manufacturer but I cant find any info on the web with this model number under either the Trielectric or DB name. TIA to all. Kev K2KMB Yahoo!

Re: [Repeater-Builder] buillding a repeater
The other comments regarding the control line is a good one but allow me to pass on an experience I had in converting a mid-split UHF Micor station (C64RCB) to the ham band. Specifically, it needed to be moved *exactly* 10 Mhz down (it was on 451.875/456/875 and I was moving it to 441.875/446.875). Pure coincidence but there you go... The receiver was no sweat - it tuned to 446 painlessly. The transmitter was another story, perhaps because it was being moved so low. What I found was that the exciter was no biggie, as it tuned down easily enough (although I did parallel a 1 pf cap across 2 or 3 coils to center them in their range a bit better than they would without the new caps). Of course, the exciter makes power on VHF and is later tripled. But you can hear it just fine for quite a distance on its ultimate UHF channel. I followed the directions on the repeater builder webpage regarding tuning the SECOND bandpass assembly and the circulator but still couldn't get *any* power out of the PA. What I found I needed to also do was retune the FIRST bandpass filter assembly - the one between the exciter and the tripler stages. Once I did that, there was no problem at all in the xmtr making power. FWIW Ken At 09:34 AM 6/2/2004 -0400, you wrote: I have a problem. I have a micor base/repeater and over the weekend I tuned it up to my frequency and was testing out and I am not getting any power out the exciter is producing some power as I can hear the radio a hundred feet away with it going into a dummy load. the watt meter tested okay on another radio. the pa is getting power and I have tried adjusting the power control to no avail. I don't think the triple low level amp is working. but I am not sure how to fix it. Yahoo!

[Repeater-Builder] Re: building a repeater
David. If you don't mind I'm taking this back to the mail list, as there may be others who can benefit from the info, ok? The first bandpass filter is located behind the exciter board. If you carefully remove the board, you'll see a piece of white teflon coax leaving the board and plugging into a 3 stage filter assembly. The output of this filter then goes through another piece of teflon coax to the tripler stage. In other words, forget about the tripler at this point. Since the filter in question simply unplugs from everything, I just pulled it completely out of the chassis and tuned it on the bench, using a tracking generator and, of course, 3 db pads on the input/output. It is almost impossible to tune it with it mounting in the chassis anyway. Since (as I remember) you don't have a tracking generator, you can use a low power radio and a wattmeter if you want. Just tune for maximum throughput and don't worry about using pads. Once retuned, drop it back in and you should be set.

Re: [Repeater-Builder] Re: building a repeater
when I remove it to tune it do I need to supply power to it? or will that become evident when I get it out. - Original Message - From: Ken Arck [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, June 02, 2004 2:07 PM Subject: [Repeater-Builder] Re: building a repeater David.

[Repeater-Builder] 2 repeaters on 1 antenna
With the talk of 2 rx'ers on one antenna...what about this; I have purchased a RC210 for my repeater. Here is what on the repeater; GE Mastr II UHF running 60 watts out of cans ARR preamp DB420 at 190' TM-G707 remote base Diamond Tribander at 125' (for remote base) Moto. B/R 1500 series cans I am wanting to stick a low powered UHF repeater on the same antenna. This would be an optional control rx'er for the main repeater but will run full time ISS audio (when FCC approved). This would be on the 3rd port of the RC210. The low power repeater would probably be in the 442.000 range at about 5 to 10 watts. Would run one of the small mobile duplexers. I have heard about multi-couplers, etc. but not sure exactly what I will need to make this happen. 2 questions 1) How much desense will this cause? 2) What equipment will I need to make this happen (multi-couplers, etc.) and what to expect on cost? There is the ATL Hamfest coming up this weekend and will want to pick up parts then. The other repeater will be stuff I have. (GE MVP, PPL6060 or 599's) Ideas?

A receiver multicoupler and transmitter combiner system is usually quite expensive and lossy. Depending how far/close the involved freqs are too, this factors into the amount of loss as well. As for duplexers though, you don't need 'em with such a system. To get a better idea of what's involved in such a system, here a couple of links that may useful. http://www.rfsworld.com/index.php?p=23 http://www.anglelinear.com/couplers/couplers.html (BTW, AngleLinear makes some of the best stuff on the market, IMHO) Ken -- President and CTO - Arcom Communications Makers of state-of-the-art repeater controllers and accessories. http://www.ah6le.net/arcom/index.html AH6LE/R - IRLP Node 3000 http://www.irlp.net Yahoo!
