RE: [Repeater-Builder] Help with Sinclair Q-202G

The two end pieces, the ones that connect to the receiver and transmitter, can be any length that fits. Please use RG-214/U double-shielded cable, in lieu of single-shielded RG-213/U cable. You won't regret it! Since you mention eight pieces of coax, I wonder if perhaps you have the earlier version of the Q-202G duplexer. All of the Q-202G duplexers that I have converted had four cavities, and the cable harness comprised five tee connectors and two male N plugs for a total of six pieces of cable. Don't get wrapped up with wavelengths, because Sinclair wasn't that concerned about it; the high-split (150-174 MHz) harness had 12 spacing, and the low-split (138-150 MHz) harness had 14 spacing. 73, Eric Lemmon WB6FLY And a fast test is to add a right angle adapter to each end of the existing cable pieces. The average right angle adapter adds about an inch, so adding one to each end will lengthen the cable to 14 inches, plus or minus... Now, I wouldn't use adapters for a long term solution, but it works for testing. Mike WA6ILQ
[Repeater-Builder] Motorola Part Needed
Hi everyone, I'm in the need of a high power RF MOSFET. It's stamped 33P71 and is made by Motorola. Doing some checking, it appears this device is better know as a 4882233P71 or a SRFM33P71 or even possibly a XRFM33P71 device. It was part of a hybrid assy. that failed. I removed the part and popped off the lid and, yep, this is the component that failed all right! All the magic smoke had been released! So, I'm wondering if anyone has an old power hybrid laying around that is of no more use to them with a component like this attached to it yet? I'm willing to pay a fair price for it if it's still a good part. Don't need another bad one! Or, ideally, possibly someone has come across a source to purchase these from other than Big M? They want a pretty good dollar for them and I'm sure they are available form some supplier for a whole lot less. Prefer a local supplier instead of on of those online, off shore places that are all over the web. Thanks!

[Repeater-Builder] icom f221 radios
Hey guys, alright i need some input here. Thinking very seriously of getting few icom f221s and using them as repeaters. My concern is with the audio quality. Can these things do direct FM?

Re: [Repeater-Builder] Help with Sinclair Q-202G
Collin, it depends on what vintage Q-202G you have. I have four duplexers that have the rexolite rod caps to adjust the notch frequency on each cavity, and I brought them down into the ham band by increasing the length of the jumper cable that connects directly to the cavity from 10.5 inches to 12.5 inches. I also came up with a manual and Eric Lemmon scanned it into a PDF file and posted the manual on the repeater-builder site. http://www.repeater-builder.com/sinclair/q202-208-218-tuning.pdf The manual explains how to tune the duplexer to a new frequency. What you have to keep in mind is that the first piece of cable connecting to each cavity is part of the notch circuit and that piece of cable in conjunction with the variable setting of the dialectric rod determines the frequency of the notch. Also keep in mind that this circuit produces a notch above and below the center frequency the cavity is tuned to, and the high and low sides of the duplexer have identical circuitry. 73 - Jim W5ZIT [EMAIL PROTECTED] wrote: Dear Friends, I am working on retuning a Sinclair Q-202G duplexer to 144.810/145.410. The question I have is about the new cables I will need. First will I need all new cables? What I mean is there are actually eight pieces in all. These need to be 1/4 wave each? Also when measuring these I know the measurement is from the center of the T connector. When measuring to a connection on a stub where is the measurement taken from? I have some RG-213 cables which measure 12 from T center to T center. Anyone that can help would be greatly appreciated. Thanks, Collin - Never miss a thing. Make Yahoo your homepage.
[Repeater-Builder] Re: icom f221 radios
Hi Jed, One might assume any newer generation of radio should be able to operate digital coded squelch DCS (aka DPL). I wouldn't know about any discriminator audio availability from that radio... I myself sell one of the other brands (Kenwood). Don't expect the radio to output full power 24/7. As with many mobile radios the heatsink will get warm/hot and with a bit of luck the power protection circuit will then greatly reduce or even cut off the rf output power. So for many repeater applications... it's more than prudent to run them on the low power setting and or place a fan/blower on the heat sink and hope it stays cool in lock to talk operation. Depending on the mass of the heatsink and the air movement past... it's quite possible to pull off a fair amount of full power operation before the protection circuit throws out the reduce power anchor. cheers, skipp Jed Barton [EMAIL PROTECTED] wrote: Hey guys, alright i need some input here.

Should be quite the smokin' signal when you have the amplifeir in line. It worked fine for a number of years and then suffered what appeared to be lightning damage. The insulator between the plate line and the plate tuning disc was arced through among other damage. It is a rectangular piece of clear material that looks like mica. If it is a clearish but dark material it probably is mica. If it's the thicker white insulating material it might be beryllium oxide, which has danger warnings about breathing any dust from the material when drilling or cutting into it. I tried adding some Teflon tape to cover up the puncture. Nope, ain't gonna work. When I fired up the amp today, It arced through again during the tune up process. Anyone have suggestions for a replacement or have one in their junk box? John Lock kf0m at arrl.net Google mica sheet and or look at companies like McMaster Carr. You can often find small sheets and parts at woodstove and appliance repair places/stores. www.antiquestoves.com is one place I found some mica sheeting available on line.

Re: [Repeater-Builder] Re: icom f221 radios
On the topic, I'm looking for good mobiles to make repeaters from. I like Motorola a lot, but programming software is expensive and so are the radios. With that said, I'd like to have access to on the back of the radio to: RX audio at a reasonable level (not speaker) (muted by COS _OR_ PL) Carrier detect (COS/COR/Noise Squelch) PL detect TX audio at a reasonable level (not an un-amplified mic level input) PTT PL strip (turn the PL on/off at will) Cost $250 range Programming software $arm+leg In any event, I'd use the transmitter as an exciter in the 1-5w range, so expect that heat should be a problem in that range of output. So I've taken this discussion WAY far to the other side of the F221 perhaps, but I think this is kind of a universal need for many of us. My main reason for this is that I'm looking at making a system with multiple remote receivers. I'd like one radio building block that could perform any of the functions from repeater main receiver or exciter, to remote receiver, link transmitter, link receiver, etc. If I could find one cost-effective radio to use this way, It would make life really easy (I know, life's not fair, but we could get a break every now and again?). 73 DE N0MJS On Feb 25, 2008, at 11:02 AM, skipp025 wrote: Hi Jed, One might assume any newer generation of radio should be able to operate digital coded squelch DCS (aka DPL).

[Repeater-Builder] Re: icom f221 radios
Hi Jed, Of course I'm going to say yes... regarding Kenwood Radios doing what you wantever you might want to try. You can make a repeater out of almost any two radios regardless of brands... it's just a measure of how creative you want to be. If we're talking only the 2 Meter Band here... Kenwood makes a really impressive radio, the TM-271a. I'm a Kenwood Business Radio Dealer so sad for me that I don't sell that model... :-( I still own a few 271a radios and use them all the time... 60 watts output and I haven't been able to kill it even in constant service. I have made more than one repeater and link packages out of the TM-271a. If you're talking non amateur applications Kenwood makes a really fine line of commerical radios of which I do sell. I've made repeaters and links out of almost every model kenwood mobile going back some years and even a lot of portables (hand-helds). Many Kenwoood Commerical Radios give you the option to purchase a flying pig-tail lead wire kit (under $20 typical) bringing out to a jack/plug the various desired functions you might want to use. Some of the newer Kenwood Radios have the multi function jack right on the back of the radio chassis. For commercial work I need the type acceptance radios for operation outside the amateur band(s). Regardless of where you buy a Kenwood Radio... as time allows I will try to help folks with information, parts and service. Heck we even try to help with pretty much any brand radio you might have around. And of course there is the magic of the Repeater Builder Group here as an A-#1 resource. You need a laugh... I'm still making Links and Repeaters out of old Midland Syntech Radios so you can see we're also into a measure of self abuse. Darn Syntech Radios last forever and I haven't yet been able to kill the PA in full power repeater operation. Depending on your budget, you can buy new and used radios off ebay, me and a bunch of other group members who sell equipment full and part time. Don't forget to ask Kevin and Scott if their converted commercial radios will work for your application. And don't forget they sell conversion kits if you want to roll your own. The bottom has fallen out of the land mobile (two-way) radio industry and we're seeing major surplus equipment dumping on ebay and at flea markets.

I really like the GE MVP, Master II and Mitrek mobile radios and they pop up on Ebay and used markets all the time. Programmable radio wise... many of the used Kenwood Mobiles Radios make great price sleeper deals. I've made repeaters out of older tk-840 radios and other tk-series models. In some cases it's just add the flying cable lead and wire it up to your desired repeater controller of choice. The same goes for many other radio brands/models.

Re: [Repeater-Builder] Motorola R100
Yes you will need to retune the TX vco voltage to lock it on frequency, and retune the front end filter, and vco, anfd you'll be good to go. The only thing I would recommend would be to wire in an external controller, and program the repeater to carrier squelch. So if the external controller fails, you can swtich to a carrier squelch repeater. As far as performance goes, I have 5 of them in service as portable emergency ham repeaters for our ARES/RACES group. They work great. We built them into a 6 space SKG rack case, and all we do is grab and go. If you have any more questions, shoot me an email. I also have pictures of the wiring I used for the external controller. We use the Zetron model 37 max controllers, and work great. 73's Dirk -- Original message -- From: kd7yuw [EMAIL PROTECTED] I have the hacked software to program out of band for the Motorola R100 but wondered if there would be any retuneing to be done once I move it to 444-449 area of the band .

Re: [Repeater-Builder] Amateur Mobiles as Repeaters, Part 13
Because we really had little experience in repeaters at the time (late 1970's), our club used a ICOM 22A for many years as the repeater receiver. We just poked around and found a signal that looked like it was useable to control the COR and used the front panel volume and squelch controls for the repeater audio and squelch levels. No one ever noticed we were using a mobile rig for over 15 years. It finally bit the dust after a lightening bolt (we theorized). But for many years, it was as sensitive as any thing I have seen.

Re: [Repeater-Builder] Amateur Mobiles as Repeaters, Part 13

Anyone had good long-term success with anything else? Especially shielding, presence of logic and audio signals without butchering the radio (installing an option cable isn't butchering, cutting traces and soldering in here and there is), and a PA that doesn't melt down even when run at much lower power with a fan? Kenwood TR-7950. I had one plugged straight into a Yagi @ 5700 ft. for many years never one burst of IMD. RX was sensitive enough to outperform a co-located 440 RX with GaAsFET preamp (foliage absorption was the likely reason for the difference in performance). The RFPA is able to handle continuous duty but does need a fan. There are also pots on the RFPA board that can get dirty can cause the output to drop go spurious. Bob NO6B

Re: [Repeater-Builder] need Mitrek
Colin, I have a Canadian VHF Mitrek 2-10W repeater. All built-in to one mobile unit. controller with pl (all factory Moto. stuff) along with cable and control head and a speaker. The TX was tested on 146.10 and works the RX side did not. The main pc bd. looks the same as a standard mobile BD. so trouble shooting the Rx side shouldnt be that hard. I'm in Jasper,Ga. if you are interested in looking at it. -- Doug N3DAB/WPRX486/WPJL709 [EMAIL PROTECTED] wrote: = Dear List Members, I am working on a 2 meter repeater using a Mitrek mobile.

Re: [Repeater-Builder] need Mitrek
Yes it is doable I have several on the air right now very little trouble since installation just keep fans on them if using for TX. I have one running 125 watts without a fan (low duty cycle repeater TX) and a couple on two meters that I helped put together for a club that see pretty high duty cycle. They had a couple fan failures that made the Syntor X's mad. But the nice thing about it is you just grab another one and swap the EEPROM module and you are up and running again. 5 minutes tops. RX will be pretty deaf without retuning but the TX plays with out modification although if it is colder than 30 degrees ambient the TX may not transmit without some optimization but for the most part you can take any of the 150-174 units and use for transmit without doing anything other than programming the EEPROM. I think the Syntor X and X-9000 was the last great mobile radio that Motorola made. Been downhill ever since. tom [Original Message] From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Date: 2/26/2008 12:54:05 AM Subject: Re: [Repeater-Builder] need Mitrek Tom, Thanks for the reply.

[Repeater-Builder] Re: New file uploaded to Repeater-Builder
The files uploaded are information about D-STAR Digital Voice Data technology. D-STAR is an open protocol created by the JARL and designed for the amateur radio environment. Any manufacturer can make equipment for D-STAR. Icom is the first major manufacturer to produce D-STAR products. However in the USA there is a great deal of independent innovation occuring in the D-STAR environment including products such as the DV Dongle, dplus gateway software, d*Chat messaging software and D-PRS GPS coordinate tracking APRS integration to name a few. D-STAR repeaters have been are being implemented across the country internationally and these files are provided as resource for the group. 73, Mark, WB9QZB --- In Repeater-Builder@yahoogroups.com, [EMAIL PROTECTED] wrote: At 2/25/2008 22:15, you wrote: Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the Repeater-Builder group.

Re: [Repeater-Builder] need Mitrek
Tom, Sounds like that might work well for me. I want to get this thing going. How do you program the EEPROM?
