Re: [Repeater-Builder] RP-70U repeater not transmitting at full power
You sure it's 15 watts? The service manual on repeater-builder specifies it's a 12 watt repeater http://www.repeater-builder.com/standard/standard-index.html Add in the duplexer, cables, age, possible tuning out of it's designed 450-470 range and you get about 8 watts.

Re: [Repeater-Builder] MSF5000 CLB Eprom Programming Template
If this was a stand-alone repeater, instead of a base-station, I'd think you have the repeater-activate and repeater-holdin parameters set differently, such that it needs carrier and PL tone to bring up the repeater but the holdin is missing or OFF. However, in a base-station configuration, the only field that has meaning is the receiver audio control / activation. I'd suspect the signal polarity and/or level feeding the CAT controller is incorrect or needs a pull-up on the input. What points in the MSF are you using to supply the COR and CTCSS input signals? Is the CAT set up to require CTCSS? There's an AND/OR switch or field setting in most CAT products. There's a test point in the SCB that has raw receiver audio. Put a scope or voltmeter on this point and verify that you still have signal coming through when the CAT keys the transmitter. Also verify the PTT signal coming out of the CAT is keying the transmitter when you provide the proper INPUT signals to the CAT. In other words, disconnect the COR and CTCSS lines and activate them manually to see if it's the CAT or the MSF that's not working the way you want.

[Repeater-Builder] MTR2000 Temperature issues?
We have an MTR2000 VHF repeater deployed here in Michigan, and have been quite happy with now, for more than 3 years. This winter has been particulalry brutal, and the temperatures have taken many excursions to significantly below 0 degrees F, for many days in a row. Adding to this issue, the building housing our system has lost many equipment cabinets and running systems. It is actually colder in the building than outside. During the past few weeks, especially when the temperature has plummeted, the repeater has developed an issue. The symptoms appear that the receiver is off frequency, that is everyone's audio through the receiver is slightly distorted. Using the RSS software and a service monitor, the receiver appears to be on frequency. There are no other indications of anything amisss, yet a restart of the MTR2000 clears up the problem. Have any of you encountered a similar issue? Thanks; Jim WB8AZP

Re: [Repeater-Builder] Re: MSF5000 CLB Eprom Programming Template
First thing I did was check the schematic. U832 pin 11 comes from the microprocessor and goes high when it wants to pass RX audio through the station. This would feed the transmitter and control line output. TP9 is the local mike PTT input. Your PTT Priority has L in it so this would allow the local mike audio to go through the station as well. I'm not sure, but I think that the MSF will only let one audio signal pass through it at a time. This is why there's a PTT Priority field. You've got LW so the local mike has priority followed by the wire line. If this does operate as I think, once the mike PTT line (TP9) gets grounded, this shuts off any other audio source and routes mike audio through the station. You didn't specify the pin number on U834 where you're feeding TX audio into. I think you're mixing and matching several incompatible signals here, while also trying to interface the CAT controller to the station. I'd connect a scope to U832 pin 11, feed a signal into the receiver with a valid PL, then ground TP9 and see what happens. If the COR signal goes away, that's one problem. If not, then many of my assumptions above are incorrect. Also check the summed audio output at TP1 and make sure receive audio stays there with TP9 grounded. You might consider connecting the COR and CTCSS inputs on the CAT together. I don't recall if switch or zone settings deal with whether you are using or not using CTCSS. You'll have to check and set the polarity properly. You probably don't want ANY timeouts set if you'll be using an external controller, as the CAT has its own timeouts in it. Full-Duplex should only pertain to the wireline remote control, but I'd set it to FULL just to be safe. I've never played with any CLBs or the R180x programmer, but it sounds like you're right on top of things. There are a couple of articles on the web that deal with interfacing and programming CLB stations. I haven't checked them recently but perhaps these will give you some additional choices.

Re: [Repeater-Builder] Re: MSF5000 CLB Eprom Programming Template
Put a scope on your COR signal and check to make sure it's going lower than 1V and higher than 3.5V. If not, some form of buffer will probably be needed. The CAT expects close to TTL input signals. Also make sure the power supply feeding the CAT stays high enough (typically above 14V) so the on-board regulators operate properly.

I'm not sure, but I think that the MSF will only let one audio signal pass through it at a time. This is why there's a PTT Priority field. You've got LW so the local mike has priority followed by the wire line. If this does operate as I think, once the mike PTT line (TP9) gets grounded, this shuts off any other audio source and routes mike audio through the station. You didn't specify the pin number on U834 where you're feeding TX audio into. I think you're mixing and matching several incompatible signals here, while also trying to interface the CAT controller to the station. I'd connect a scope to U832 pin 11, feed a signal into the receiver with a valid PL, then ground TP9 and see what happens. If the COR signal goes away, that's one problem. If not, then many of my assumptions above are incorrect. Also check the summed audio output at TP1 and make sure receive audio stays there with TP9 grounded. You might consider connecting the COR and CTCSS inputs on the CAT together. I don't recall if switch or zone settings deal with whether you are using or not using CTCSS. You'll have to check and set the polarity properly. You probably don't want ANY timeouts set if you'll be using an external controller, as the CAT has its own timeouts in it. Full-Duplex should only pertain to the wireline remote control, but I'd set it to FULL just to be safe. I've never played with any CLBs or the R180x programmer, but it sounds like you're right on top of things. There are a couple of articles on the web that deal with interfacing and programming CLB stations. I haven't checked them recently but perhaps these will give you some additional choices.

[Repeater-Builder] Re: micor base station
The TLN4666A backplane is a component of the TCN1107A Non-Unified Chassis. The cross-connects and schematic diagram are on pages 8 and 9 of the Micor Control and Application Manual 6881025E60 which, unfortunately, is NLA from Motorola Parts. Fortunately, however, I scanned that document in full-page format about six months ago and submitted it to RBTIP, but I think it got lost in cyberspace. If you'll send me your e-mail address privately, I'll send you those two pages. 73, Eric Lemmon WB6FLY -Original Message- --- In Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com , jmhecko jmhe...@... wrote: I got a Micor base station with the ribbon cable backplane.
