Re: [Repeater-Builder] Micor Repeater - ID?
Eric and Joe, Thank you for your replies. Assuming this repeater is in functioning (or near-functioning order) on its current frequency (464.050), is it possible to take it down to amateur frequencies? From what I read on the repeater-builder website, it seems like the procedure would be to (paraphrasingsimplifying here) replace a set of capacitors to retune the repeater and then send the channel elements to a crystal house to be re-crystalled/calibrated. Is this correct?

[Repeater-Builder] Re: Midland Land Mobile Model 70-9020 (Midland Power Connectors)
Hi Trevor, There are two basic Molex style power connectors for that era for Midland Radio. The standard power connector and the high-power connector (which has two larger pins for the higher current requirements). For Midland stuff, you do well to check the files and photos sections of the yahoo midland group, which is similar to the repeater builder group but focused mostly on Midland Radio Products. http://groups.yahoo.com/group/MidlandLMR/ There's probably a yahoo or google group for about every major brand of radio. In some cases more than two or three with some of the more popular radio brands. cheers, skipp Trevor [EMAIL PROTECTED] wrote: Hello group:I need pin out info on this radio of the rear power connector so I can play with it !! any one help me outits 15 watt 800 mhz trunking 200 channel radio,, thin black ,,with plastic bottom cover... any info or file locations on the net would be nice as well..

RE: [Repeater-Builder] Micor Repeater - ID?
Actually, the C in RCB means continuous duty. If it were a T as in RTB it means intermittent duty. I found this information in almost every Motorola Micor manual I own. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of MCH Sent: Saturday, February 02, 2008 9:48 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Micor Repeater - ID? Actually, the 'RC' indicates a Micor Unified Chassis and the 'B' indicates 120V AC Power source. And the '1' listed as N/A means 25 kHz channel spacing for that band. Joe M.

Re: [Repeater-Builder] Mitrek repeater
Hello Collin, I would concur with your choice of the Mitrek. They are inexpensive, easy to find, and work well in rpt. use. You have several choices of channel elements for different fx. stability, and the rec. has a plug in preamp (optional). I have built several rpts., using SEPARATE radios (they are cheap), using just the rec. in one box, and the xmitter in the other.I wired a ZETRON controller to each Box. I used WACOM duplexers. I would mention, there are several different power levels of transmitter sections, and of course you always want to run them slightly under the max output, WITH GOOD COOLING, If duty cycle is high! I have a repeater on VHF that has been in service for eighteen (18) years. It is a Motorola MSR 2000. You guessed it!! It is basically a Mitrek chassis, with a 110 watt PA. Other than a yearly check up, it has never let me down. There are many rigs out there that would Fit the Bill for rpt. use, but having used the MITREK for rpt., remote bases, packet. I tend to lean towards the MITREK.If you want to Get your feet wet, this would be the chassis for you.(Easy to work on too!!) Regards, Tim Hardy [W7TRH / AFA5TP / TIMSKAKU Vashon Is. Wa. -- Original message -- From: [EMAIL PROTECTED] Hi, I am building a 2 meter repeater. I was leaning towards Mitrek radios. Any ideas or warnings? Pitfalls to avoid?

Re: [Repeater-Builder] Micor Repeater - ID?
Mike, I think you need to know the following: The receiver is in the bottom of the unified chassis. It has a BNC connector, you should find that on the left hand side facing from the rear. The un-labled N (F) connector by the silver box is the transmitter output. Commercial repeaters are High In / Low Out, so should be 469.050 / 464.050. Likley there is also a PL or DPL element in both the Rx and Tx strips unless it is a CR backplane, then you will have the PL and/or DPL 4 user card and master decoder card. And, to answer your important questions, yes it should go down to the 440 ham band. Make sure it works on its present frequency and record how well, i.e., transmit power, recieve sense, etc... then follow the instructions on the repeater builder page for conversion. Good luck, thp Big Snip

[Repeater-Builder] Low-band MaraTrac Squelch Pots
I'm working on a 42-50 MHz MaraTrac with the A7 advanced head that has a squelch pot on it. The squelch is open all the time, and neither the control head pot or the pot inside the radio will close the squelch. The radio does go quiet if I program TPL/DPL on the channel and ground the mike hang-up button. The service manual I was able to look at didn't have anything about this remote squelch pot in it. Does anyone have a MaraTrac manual that HAS the squelch pot details in the control head? I'd need info about the wiring inside the radio. I was able to trace one side of the pot to pin 9 of the radio end of the control cable, and I can see a varying resistance value there (to ground) when I rotate the pot. From that point on it's a mystery. I suspect a problem on the audio interface board. I don't know if this particular control head and cable belongs with this radio. I will pay for copies of the appropriate sheets. Please let me know privately if you can help. Thanks. Bob M. Never miss a thing. Make Yahoo your home page. http://www.yahoo.com/r/hs
RE: [Repeater-Builder] Low-band MaraTrac Squelch Pots
Hi Bob, There’s a schematic of the Audio/Squelch board on Batlabs, here... HYPERLINK http://www.batlabs.com/maratrac.htmlhttp://www.batlabs.com/maratrac.html Look about a third of the way down the page. There’s also some info there regarding the head-mount squelch control. Might be all you need. Good luck! Brian W.
