Re: [Repeater-Builder] Re: Discriminator audio
The R-100 has two fixed outputs available. De-emphasized audio is available on terminal E1, but I would not recommend using it. The audio level is only about 100mv p-p at this connection. A better choice would be the Discriminator Audio output on terminal E5. This is capable of 2 volts p-p and I believe the RLC controller would like to have 1 volt p-p at it's input. If you use the discriminator output of the R-100 you will have to look into the RLC manual and find the jumper option to add the de-emphasis filter to the circuit. It's in the manual for the RLC under Connecting the Receiver Audio. 73, Joe, K1ike mickupi wrote: - -- I am using the R-100 Hamtronics receiver. Mick
RE: [Repeater-Builder] Yaesu FLT-1011 on 6m band.
Thanks for all replys, My software version is 6.22 and do not let me changes out of band. I found this soft at www.hackersrussia.ru http://www.hackersrussia.ru/ freely, may be you have other version than mine. I appreciate if you can send me the right stuff at [EMAIL PROTECTED] or maybe a link where I can download it. Thank you.

You need the older software to program the 4-12-24 channel radios, and a newer version of the software for the 99-channel radios. No hacking needed. The radios will have to be re- aligned.

[Repeater-Builder] Re: Discriminator audio
Hi Mick, In your case the best choice is probably based on your controller being able to take discriminator audio direct. Most any controller designed to operate from discriminator audio would be the most practical option and you would be able to use the speaker audio for local at-site monitoring. We would assume the repeater controller using a discriminator input option would properly handle the audio, which includes any ctcss (sub tone) information on the received recovered signal. There are actually at least three audio source options for most receivers like the Hamtronics Units. You can use/tap the discriminator output, tap/use the high side of the volume pot (control), which has squelched and de-emph audio but sometimes no ctcss filtering and third ... the speaker output terminated onto a resistor. In many/most cases the reported speaker output distortion is not anything to get excited about... it can be/is often quite usable and in many/most cases un-noticed by most repeater system users. In a basic repeater system terminated speaker audio remains a very viable option. So you get three mints in one... cheers, s. mickupi [EMAIL PROTECTED] wrote: I am running a Hamtronics receiver on our 53.090/52.090 repeater.

[Repeater-Builder] 6 meter repeater Identification and help
Hello group, I have four Motorola repeaters in the 48-49 MHZ range. The fifth is high VHF. 1) Can anyone tell me what they are? 2) Any leads for information or people that might know how to convert the equipment for ham use? The repeater model is B61LPY 3100DT SPL (it looks like) The duplexers are model R-103G Pictures are posted on my site: hteeteep://aa9nv.r2i.net/Repeaters6M.htm take out the extra ee's :) Any help would be greatly appreciated. Thank you, Travis AA9NV
[Repeater-Builder] On The Air!
Well, I finally got the opportunity to change out the repeaters on my 900 MHz pair - the temporary repeater (which belonged to Ryan - K9ZOE) was taken off the air and my machine was placed into service. I am now operating on the machine I built. Woo-Hoo!! Unfortunately, it seems there is a bit of desense associated with it and I did not have a service monitor to bring along with me today. But at least it is on the air and playing relatively well. I did note a high level of noise on the band (it actually opens the receiver on my HT) so I'm not totally certain that the problem is in my equipment. (Maybe 900 MHz cordless phones in the building? This is a senior citizen high-rise.) I plan on making another trip to the site after the holidays to do any necessary tweaking - I figure this will give the repeater some time for a shake-down run of sorts. I'll bring all the test equipment necessary when I go back up. Mark - N9WYS N9WYS/R 927.5250 / 902.5250 PL151.4 (Joliet, IL)
Re: [Repeater-Builder] 6 meter repeater Identification and help
The repeater is a 120 watt continous duty Motrac with factory PL and no extender, I think. The duplexer is a exactly what the label says. I have had one operating on 6 meters for about 15 years. They need slight modification to go to 6 meters. -- Original Message -- Received: Mon, 10 Dec 2007 02:01:28 PM CST From: travis8303 [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] 6 meter repeater Identification and help Hello group, I have four Motorola repeaters in the 48-49 MHZ range.

[Repeater-Builder] Re: GE Mastrll
Nate is correct in that it depends on where it's going. In general, the transmitter will tune up anywhere in the 2M band. For me, if the 66 receiver is on 146 or 147, then it generally works with no mods. If the RX is in the 144 or 145 range, then I get high side injection crystals (when ordering) and it works with no mods and has good performance. The first one I tried with lo side injection down in the 145 range had poor sensitivity. Instead of doing the mods (I'm lazy), I re-ordered the crystal for high side injection and it tuned right up. Dwayne Kincaid WD8OYG [EMAIL PROTECTED] wrote: So if I found one with DC56YAS66A number, it could still be put into the 2 meter band, correct? Depends on where you're going in 2m, but generally -- yes. It's a bit of a stretch to pull them to the bottom of 2m, but they almost always go and work to factory spec. (See archives for discussion of high-side vs. low-side injection crystals, too.) Nate WY0X
Re: [Repeater-Builder] Re: GE Mastrll
It will be in the 147 portion. Rod Nate is correct in that it depends on where it's going. In general, the transmitter will tune up anywhere in the 2M band.

[EMAIL PROTECTED] wrote: It will be in the 147 portion. Piece of cake. Dot the i's and cross the t's on the coordination paperwork, tune 'er up according the factory docs, build a nice filtering/antenna system, and she'll fly. You'll probably want a pre-amp on the receive side -- factory-spec MASTR II receivers are not nearly as hot sensitivity-wise, as most (barn-door-wide) modern mobiles and HT's. In order to balance the performance of the repeater, it'll need more receiver sensitivity. It's already a very selective receiver with nice built-in filtering (helical cavities on the front-end), which is why they're popular... but adding the pre-amp then also usually means adding proper band-pass filtering if you're in a high-RF environment. That all depends on where it's being installed and your desired coverage. Most folks squeezing every last ounce of performance out of their MASTR II's have added high-quality LNA's somewhere in the receive path. It's easier to build an alligator with a MASTR II (big mouth, no ears) than an elephant (big ears, small mouth). You're shooting for something in the middle, so you probably need some help in the receiver side to make it balance out. (Remember the MASTR II Repeater/Station radios were built to be used in a system where the mobile rigs also regularly ran 100W! The design -- as originally conceived -- was balanced -- but the average ham today is using a 5W HT for almost everything. No one wants large trunk-mounted rigs with 6 gauge running from the trunk to the battery of the vehicle these days.) Nate WY0X

Hi Eric, I like you searched and found the 6.22 version. I also asked around and someone sent me a copy of what I think is the much earlier version. Email me direct and I'll forward a copy of it to you. I tried it and it seems to come up ok and it sure is early... dos computer early. cheers, skipp skipp025 at yahoo.com Eric Vincent [EMAIL PROTECTED] wrote: Thanks for all reply's, My software version is 6.22 and do not let me changes out of band.

In a basic repeater system terminated speaker audio remains a very viable option. Distortion is not the only issue in using speaker audio as repeat audio. In many cases there is additional filtering in the speaker audio chain that can degrade repeat audio. In the end it has a lot to do with how the radio was designed. I once built a barebones system using a GE MVP with speaker audio going straight into the mic input using only an 8 ohm load resistor, coupling capacitor resistive divider to get the level right. It did sound quite good, but I suspect this is more the exception than the norm. Bob NO6B
