[Repeater-Builder] Re: MSR 2000 Base to Repeater Conversion
I have done rhe conversion to make the unit into a repeater anjd it is fully functional. Yes I did use a TS-32 for tone access. I did the backplane conversion which to me was not that difficult. It accomplished what I wanted to do. I have the test set that goes with the MSR2000 and want to be able to use it. Having to go to backplane and solder on to the tabs in order to meterr the unit to me is a bit crazy when there is a connector put on the front. Motorola put it there for a reason. I want to get rid of the PL card as it is not being used as originally intended. And most of all it is in the way of using the meter socket for the transmitter. I simply need to know what pins to jumper out this board and that is all. I need no other info other than this. If you don't know the answer than let me know and I will go elsewhere to find my answer. I don't need all this other info about other conversions as I will not tear the unit apart and do someone elses way just to please them. I just need the answer to my question. My unit works fime the way it is.

It's much easier if you have the duplex back plane, which is the one with the PL and R1-Audio Modules laying horizontal above the main module slots. But the MSR-2000 like the Micor was optioned from the factory to operate one of many possible ways and that requires jumpers and certain sequence of modules come into play. If your now repeater was a base station (first), you need to ensure a number of logic functions reach the exciter (and receiver) to operate. The base station originally keyed into transmit using tone or DC and there are modules in card cage that provide channel element (crystal holder) ground in transmit mode, which in your case is probably lead through the PL Module on the way to the exciter. In repeater operation the Squelch Gate Module provides the channel element ground. First: You need to go onto the receiver and exciter board and jumper the channel elements to full time on (enabled). You need to find the two proper manuals to service the unit, one being just for the Modules in the back plane and the other the RF and specific Hardware Manual for the VHF Unit (or UHF unit if you have one on 450MHz). In the case of the Manual for the Modules, the Micor book will sub for some things (but not all). You need to make a choice... are you going with the back plane direct connection to your external device (ham or commercial controller) or are you going with the Squelch Gate Module interface method? I would assume your PL Module is half duplex (normal for a base station). You'll notice it is the same PC-Board as the full duplex version, less the parts. You can populate the board up to a full duplex version by using the chip from a normal Mitrek Mobile PL Deck. Although the manual says they are different part numbers, they are the same chip and I've made many a duplex PL Module from half duplex units. Another trick I've seen is to stack the TS-32 right onto the PL Module, often using a small sheet of aluminum with stand-off spacers.

If someone sold you a Micor Repeater Squelch Gate Module, you could simply change the end pins to the MSR type using the parts from a spare card and you'd have a working SQM, same as the original MSR type without the Ebay price hike.

[Repeater-Builder] PL tone useage
The earliest reference I can find in my Motorola paperwork is for a P-9303 Single Tone Oscillator Decoder schematic, dated 6/12/59. However, these are not PL tones, looks like tone-burst instead, listed freq. range is 600-3200 Hz. BTW, tone burst is used a lot on places like Europe on VHF/UHF FM repeaters. 1750 Hz is the common freq for that. --John WB0EQ

I will check with a friend of mine to see if he had a VNA, like Jeff suggested, at his old radio shop (I just bought all of his test equipment for my own commercial shop as a side business). I know that only other shop here locally does not have one (and the fact he deals with non FCC accepted 2 way), so I'll stay away form there. Looks like later I may have to get a VNA.

You are to be commended for your creativity in making do with what you have. Since your duplexer has been moved from its original settings, you can only improve matters. Let's review your process: You generate your 449.625 MHz receive signal with the service monitor, and inject it into the duplexer's antenna connector, with your monitoring radio set to 449.625 MHz and connected to the RX (high pass) connector of the duplexer, and a 50-ohm dummy load on the TX (low pass) connector of the duplexer. The SINAD input of your service monitor is connected to the monitoring radio's speaker, and you adjust the center rods of the high-pass cans to get 12 dB SINAD with the lowest level signal at the RX connector. Next, without changing any of the connections, you set the service monitor to generate 444.625 MHz and program the monitoring radio to receive 444.625 MHz. With your service monitor generating the highest-level signal possible (at least 0 dBm, but higher is better), you adjust the notch capacitors on both high-pass cans to minimize the received signal. You might get better results by monitoring the RSSI voltage at the radio. Do not move the threaded tuning rods at all. Next, reverse the positions of the monitoring radio and the dummy load. The service monitor is still generating 444.625 MHz at a high level, so bring the output level down to about -100 dBm or so. While monitoring the SINAD meter adjust the center rods of the low-pass cans to achieve 12 dB SINAD with the lowest possible output of the service monitor. Finally, set both the service monitor and the monitoring radio to 449.625 MHz. Crank up the output level of the service monitor to maximum, and adjust the notch capacitors on both low-pass cans for a minimum receive signal. Again, you might need to meter the RSSI voltage as you tune the notch capacitors. Repeat all four steps above until there is no improvement, since there is always some interaction between the low-pass and high-pass sides, especially if significant changes are made to either side. The primary disadvantage of this simple procedure is that the output level of the service monitor may not be high enough to achieve a sufficient signal at the notch frequency to get the tuning exact. It is true that duplexer tuning can be affected by rough handling, especially if one of the cavities gets dented. However, a high-quality duplexer is seldom affected by temperature, because the center tuning rod is normally made of Invar- an alloy that minimizes sensitivity to temperature. Keep in mind that the shack temperature is not the only factor to consider; a typical six-cavity duplexer on a 250-watt repeater will be heated by the transmitted carrier due to insertion loss of 2.2 dB, amounting to about 100 watts lost inside the cavities. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@ yahoogroups. com [mailto:Repeater-Builder@ yahoogroups. com] On Behalf Of terry dalpoas Sent: Sunday, September 20, 2009 9:41 AM To: Repeater-Builder@ yahoogroups. com Subject: Re: [Repeater-Builder] UHF Duplexers Eric, I did find my old Icom IC-2710 dual band mobile last night.

I am not sure how durable duplexers are, but I have heard sometimes the slightest shock can mistune them, and I discovered the tuning rods were not locked in place.

[Repeater-Builder] Re: MSR 2000 Base to Repeater Conversion
Howard, As the other reply also mentions... you do not plug the metering box in from the PL Module side... you tilt down the Module cage and insert it into the back plane PCB holes from that back side location. (aka dogie style). If you try to insert the metering plug into the same holes via the front direction... it probably won't work (very well). The dis advantage of doing the MSR-2000 back-plane to external controller method is the loss of gated dual squelch, which acts like the Micor Squelch to eliminate crash noise. Especially nice in/with Carrier Squelch Operation. Since you seem to be kind of an ungrateful mule head ...

Over the years the list has been expanded - by 1965 Motorola was using 26 tones from 82.5 to 192.8 Hz, and by 1983 the MSF5000 station offered 42 tones in it's list.

If you just can't get access to a VNA and someone who knows how to use it, having a 50-ohm attenuator on hand to put between the duplexer and the handheld or mobile rig can help a great deal. They can be found with BNC connectors on hamfest junk tables, (make sure they're 50 ohms,) or homebrewed fairly easily as long as you're careful with shielding.
