Re: Re: [Repeater-Builder] Re: Bad adapter
I could put the splice in a section of PVC large enough for the connectors, depending on the situation. I was looking at the cables on the local fire departments tower, and what a mess. Cables held in place with chunks of baling wire. One piece of cable flopping around in the wind, and no idea as to where it was connected. There are an odd assorment of antennas up there, including 2 4 bay folded dipole assemblies. I am joining the Volunteer fire department with an eye to helping with communications and other things that I can manage. One interesting item, only saw it through a shed window, is a, MTR2000 and a set of duplexer cans. Hmm, I still have my good old standard Motorola key... It will be a while before I know what I will or won't be allowed to do. Another project may be finding out if the siren on the tower can be repaired or not. Could be something simple. That could be top priority. The tower itself is 27 meters tall according to the info on the FCC web site. maybe 85 feet, give or take... If I were to get permission to put my repeater there, and the antenna on the side of the tower, I would not be cutting the Heliax other than needed there. But would be sure to get something better than baling wire to hold it in place, ha ha ha...

[Repeater-Builder] Re: MSR 2000 alignment problem
Hi Jim, You could run a few in-detail tests to ensure the receiver IF Bandwidth looks normal, but I'd try the obvious first. A complete receiver realignment using the Service Manual Steps, which include pre-setting the inductor cores to the charts shown in the book... aka not a re-tweak peak alignment from an nearby frequency. The manual also describes how to check and properly set the discriminator coil. Set the channel element Frequency by looking at the injection frequency (using rf leakage) on the receiver board. It will by the Frequency of operation offset high or low the IF value. Crank the PA way down to about 60-75 watts max output unless you don't use it much. Use a good service monitor with an adjustable tracking generator to set up the duplexer. Check the band-reject notches for proper placement and adjust them if they're off. If there is nothing mechanically or electronically wrong with the repeater, I would suspect and test both the receiver and duplexer alignment. Expect the properly aligned MSR UHF Duplexer to output about 45-50 watts when you put in about 60 to 65 watts from the PA. cheers, skipp Jim Miller WB5OXQ in Waco [EMAIL PROTECTED] wrote: I have a uhf msr2000 which I recently changed frequency to 464.075/469.075. Original freq was about 1.5mhz away. I sent the elements in and had them re-crystaled. After I installed them and tuned up the receiver it worked pretty well for a month. I noticed it loosing sensitivity lately so I got out the service monitor to check sensitivity. Here is the problem. If you tune the frequency trimmer for best quieting you get very scratchy audio. If you tune for best audio you loose sensitivity. I did not bother the discriminator coil but if it is misaligned will that be my problem? If aligned for best quieting it breaks squelch at around .21uv but at best audio recovery it only makes .8uv. This is with the generator passing through the duplexer with the transmitter disabled. The duplexer is factory Motorola. This is a 110 watt intermittent duty repeater and I am getting 65 watts out of the duplexer. Does this sound about right for this machine? WB5OXQ

I have a Com-Spec TS64 that I'm working on wiring to the accy plug on the 820. Frank Thanks for your help!!! KB2AYS Here are my notes on a TS-64: Red wire is + DC power in Black is ground The green wire is the AUDIO INPUT. Hook this to the receiver discriminator. Ground the violet HANGUP wire or it will stay in pass the audio mode all the time. This is the biggest single error in connecting on the TS64 - if it is acting like it's dead right out of the box (i.e. not decoding) make sure that the hang-up lead (the purple wire) is grounded. Use the white MUTE wire for decode logic output. By default it uses open collector active high signalling (i.e. this signal will go high for decode), but it needs a resistor from this pin to a voltage source to do it. If you need active low install jumper JP7 to cause the signal to go to ground on decode. The yellow wire is the ENCODE OUT. This is the audio that is run to the transmitter modulator. The orange wire is the PTT input. Ground this to switch the tone encoder on. When ground is removed the encoder phase is shifted (i.e. reverse burst), and the encoder stops 160ms later. The gray wire is the PTT OUT. This signal goes low when the orange wire is grounded and stays low for the duration of the grounded input plus the reverse burst timing. In normal mobile radio use the PTT lead from the microphone would be disconnected from the radio and be connected to the orange wire, and the grey wire be connected to the point in the radio where the microphone PTT lead was. The blue wire is the FILTERED AUDIO OUT. The path from the green wire (in) and the blue wire (out) has a high pass / low cut audio filter in line, designed to remove the subaudible tone from the user audio. This is an installers choice - You can feed the blue wire back into the receve audio connection (i.e. cut a trace and have the source go to green and the destination go to blue). This type of radio surgery is very radio dependent. Many radios have a high pass filter in them from the factory and in that case you can simply tape off the blue wire and ignore it. Mike WA6ILQ
RE: [Repeater-Builder] Delayed PTT on Micor
Where are you connecting your ptt signal ? Watch the voltage on the ptt line with a volt meter it may not be going low enough. (I doubt this is the problem) Watch the voltage on the ctcss line (both with controller hooked up and controller disconected) and make sure it is in range of what the controller wants. Put the controller in carrier mode and see if the delay problem goes away. If the problem goes away put it back in ctcss mode and jumper the ctcss input on the controller to ground, assuming it is set up for active low. you may want to disconnect the ctcss wire from the micor and jumper it there. Then run the repeater this way and see if the delay problem is still there. This will prove it is ctcss signal voltage related. I remember trying to help a friend troubleshoot the same problem on the same setup you have and I think the controller did not like the ctcss signal or cos signal from the micor. It seems like one of the signals was not going low enough I suggested he use a relay to take the signal to hard ground. I can't remember what he actually did. You may have to buffer the cos or ctcss with a transistor because the signals do not go low enough if I remember right. You could try disconnecting the controller and running the ptt wire to hard ground by hand and see if you still have the delay problem. The normal delay in the micor ptt is only 150 or 200 miliseconds or so I think . Hardly noticable. hope this helps tom n8ies [Original Message] From: georgiaskywarn [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Date: 4/25/2008 6:38:34 AM Subject: [Repeater-Builder] Delayed PTT on Micor I am having an issue with a Micor Station and a RC210.

Re: [Repeater-Builder] Repeater Power Amplifier sent in a paper bag
There's a thread in one of the vintage stereo groups about problems with shipping companies and their not honoring damage claims. UPS and FedEx seem to be the worst, with DHL better than the two. I had one shipper who literally threw about 50# worth of assorted radios and parts into a thin single-wall corrugated box, wrapped with a bunch of clear packing tape. About half of the radios were broken , and one was in such a bad shape that I really can't do much with it besides let it sit on the shelf. n9wys wrote: It apparently didn't come UPS, did it? They are anal about the way they accept packages (at least in these parts) probably because they have a tendency to bash-up everything they ship. (Hence: United Package Smashers) ;-p Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com On Behalf Of skipp025 Re: Repeater Power Amplifier sent in a plain brown paper bag Just one of those scratch your head things... I bought a repeater rf power amplifier off ebay this month. The seller sent it out wrapped only in a brown paper grocery bag. Only the folded over open end had clear tape to seal it. The big surpise is how it arrived in pretty fair condition... less one of the 19 inch rack mounting ears being bent. The bag had no holes or tears. Once in a while I get lucky... :-) s.
