Re: [Repeater-Builder] FCC Enforcment
There are some pretty good toys out there for transmitter locating . Doppler Systems makes a special version of there famous Doppler, which has a roof pod and all the pre laid spots for connecting the different length antennas, a magnetic compass, ands a GPS antenna, there is an interface box where it all comes together and hooks to a laptop where you run mapping software, and .it takes you right there. I have used this setup a couple of times in the past and i loved it . The FCC's latest toys are even better. The best thing to hit the Internet in years - Juno SpeedBand!

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Well from what I see, that is what I have, the head that has the volume and squelch also has the 4 channel selector with it, as well as the power button. But if I unhook the the scan head, then the volume goes nuts. I have no way of knowing if this was all that was with it, they were just given to me and nothing is know about them. But you are right, without the pinout locations, I am just working in the dark. Want to see if it works before I make the attempt to convert it to a repeater.

RE: [Repeater-Builder] Micor 4 Channel Help Needed
it sounds like you do not have all the assy's for the radio. you would need a control group book and a connector tool to rearrange the cables. The best bet is to get the rig over to someone close to you that has a working test setup to check the rig. Or get a non scanning 4 channel cable and head from e-bay.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Let me ask this, I have two control boxes on here, the first is the scan head, then there is the actual control head that has the volume control on it. The wires you mention are going to the scan head. If I take Pin 4 to the connector #11 on the scan head, the volume goes sky high. Pin # 11 on the scan box goes to pin 21 on the control cable. Also, what is the brown connector used for? That is where the wire comes from pin # 4 is going to.

RG-400 is stranded center conductor. If you have a solid center conductor, it may be RG-142 that you have. RG-400 and RG-142 will give about 75 dB isolation from leakage. Foil & braid shielded coax will give about 90dB. Hardline (solid copper tube) will give about 110dB of isolation. So, hardline is the best at 110db isolation. I would use the N connectors that you have and then use a GOOD quality adapter to take it from N to UHF (not radio shack). Better yet would be changing the connector on the radio to an N. RG-400 or RG-142 would be the easiest. You could probably fit a UHF connector easily to this cable for the equipment end, and an N connector on the other for the duplexer. I would stay away from foil & braid shielded coax. I have never been happy with either the crimp or the compression connectors for this style cable. It can be used, but extreme care is needed to get a good quality connection. Then there is always the argument of noise.. Remember, some repeaters work perfectly well with RG-8 jumpers on the duplexers. Commercial duplexers sometimes come with RG-8 interconnecting cables. If you are trying to solve a desense problem, it may not be the jumpers that are causing the problem. It never hurts to use the best, but it may not be the fix for the problem at hand. 73, Joe, K1ike Repeater-Builder@yahoogroups.com wrote: Message: 3 Date: Fri, 11 Jun 2004 08:04:20 -0700 From: Mathew Quaife <[EMAIL PROTECTED]>Subject: Re: Re: Duplexer cable questionOk, couple of questions. Is RG400 a solid center conductor, or is it stranded. The Cable that I have here was supposed to be LMR400, but that is made by Times Microwave, and the cable that I used on the repeater is made by Ultralink, Cushcradt, Manchester NH. Does not really have any other figures on it. Also, if the shield is made of steel, and is not magnetic, then how would one get solder to stick to it. Or is this why some guys are going to the crimp on connectors? I have plenty of 1/2 superflex avaialable, but you are right, the connectors are hard to come by in UHF. Duplexers have type N, but it is easy to change the connector in the radio's to Type N. I also have a good amount of 3/8" hardline, FSJ something or other, Superflex cable, would that be as good as the RG-400? Thanks for the information. The help is more than appreciate.Mathew Yahoo!

[Repeater-Builder] VHF GE Master Exec II - Squelch mod?
Does any one have a squelch mod for the GE Master Exec II that will improve the squelch action and 'mobile flutter'. I used the mod on the repeater builders for the Master II and it works very well. That's changing out a .82 cap to a 3.3uf. I'm looking for the mod on the Exec now. Darryl Yahoo!

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Rather than trace everything out, just pop the shell on the control cable. Trace pin 1 and pin 4 up to the head. Pin 1 is ground and is hooked to the shield of one or more of the coax conductors in the control cable and ends up on pin 21 of the head. Pin 4 is frequency 1 and ends up on pin 11 of the head. It is supposed to be grounded when the frequency switch is in the #1 position. If you have the wrong head for the cable then the frequency switch common might not be hooked to pin 1. This is common in situations where the installation had a channel scan head and the used equipment vendor gives you a standard head. When the channel scan board is added the control head frequency switch common is rewired and connects through the channel scan board and without the board in place the switch common isn't grounded. So just ohm out the F1 wiring and make sure it's hooked up. Then make sure that you have good elements in the F1 position. Depending on the history of the radio you very easily could have the wrong elements for where the radio is tuned. I once picked up a high-range (42-50mhz) low band Micor that had been a Red Cross radio - tuned to 47mhz. The radio had mid-range (36-42mhz) elements in it on some fire dept frequency. The vendor had grabbed a radio, a random head from a bin, a random cable, a random speaker, a random microphone. As long as they plugged together he assumed they were compatible. They weren't. As it turned out, I had a cable that had been pinned for a head configuration that had a 8 freq clamshell on the bottom with a systems 90 box above it. The box had a multiple PL encoder board and a channel-scan board in it. The radio came with a 12freq clamshell, the fancy cable, a Mitrek speaker and a bad microphone. It took a while with the Micor mobile book to figure things out. By the way, P901 is the control connector - the front of the radio. P902 is the connector between the center of the radio with the exciter. P903 is the connector between the center of the radio with the audio-squelch board. P904 is the connector between the center of the radio with the receiver.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Ok, I think I'm getting the picture, it the P-902 the power connector in the fron of the radio.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Nope, nope, nope ... Exciter: frequency 1 select wire from the Channel Element on the circuit board goes to P-902, pin 15. Receiver: frequency 1 select wire from the Channel Element on the circuit board goes to P-904, pin 2. Those specific pin numbers must be grounded for the receiver or exciter to operate properly. The usual policy was to ground the frequency 1 select on the center board (Control Board) at the factory on all one frequency radios prior to shipment.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
If I understand what you are asking, pin one of each board is ground on here. There is a ground wire on the power connector that is connected to ground. Is this what you are referring to.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
You may want to determine if the Channel Element frequency select wire (one of the pins on the bottom) is properly grounded. Look at the bottom of the circuit board immediately below the Channel Element and locate the one connection that goes to the edge connector P-902 on the Exciter and P-904 on the Receiver. See that the one wire is grounded. Neil Mathew Quaife wrote: > > Xtal cases seem to be intact, was told they xtals were still in > there.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
I don't think it is a xtal issue, I think like someone said, I am missing a ground or something, something that makes the final connection between the radio and the control head. But I'm not sure where to look.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Me too, sometimes I need to open the case and read what is printed on the crystal case itself. Other times, I look at the produced signal from that Channel Element on the spectrum analyzer and calculate what frequency it is on.

Re: [Repeater-Builder] Micor 4 Channel Help Needed
Xtal cases seem to be intact, was told they xtals were still in there. Even so, I get no power output, and it does not even register a frequency on my freq counter. So no output, and no input. There is one extra plug at the control head, and a purple wire with a connector on it.
