[Repeater-Builder] Re: Amateur repeater ID's
A quick visit to the site revealed some workers had tripped the breaker on the circuit powering the repeater. I wonder if someone tripped the breaker or if it's just getting tired? If it trips again, it's probably time to replace it. Hope it isn't a long trip out to the site.

I for one have used such IDs as an indication that a repeater is still operating correctly. It also gives technical info (telemetry) of the site conditions which is a legal one-way transmission. Me too- The hourly ID lets me make sure all is well with the system during monitoring. Two days ago I noticed I did not hear the ID, found one of the Linked Repeaters not up.

[Repeater-Builder] Re: Compa Station Help
Actually, I wouldn't be too concerned about the condition of the rest of the station. As stated earlier, the channel elements are often removed to prevent operation on the previous user's channel. Not a big deal. The cards are often kept as spares, particularly if the station was disposed of through a repair shop. The missing PA power leads are a bit unusual but, at most, five minutes to replace them. If you want to make a repeater, you don't need an antenna relay but they can be found too, if needed. I wish I had a dollar for every ham repeater that is made from converted mobiles, these are ALL intermittent duty transmitters. With reduced power and a cooling fan (mainly for peace of mind) this station will be more reliable than 80% of the so called continuous duty ham gear out there. I'd take that station anyday in preference to a Kensu desktop repeater. The receiver is easily converted with a recoiled RF front end available very reasonably. Your biggest challenge is going to be that HIGH split transmitter. Tom --- In Repeater-Builder@yahoogroups.com, Milt [EMAIL PROTECTED] wrote: Intermittent duty base station that has been robbed of parts. No channel elements in the receiver, probably none in the transmitter. No station control card. No high current leads to the final. As noted by earlier posts this is not a unit that will handle long periods of transmission. Also no antenna relay (not that you need one for what you want to do). Given the number of missing parts I would be very suspicious of the overall condition of the unit.

Most always one can get to them thru a panel behind the receiver. Same with some exciters. There were 3 ranges for VHF as someone stated. Wonder what the heat sink looks like. The continuous duty has large 17w x 7h x 6 deep heat sink. Otherwise it is built into the main chassis or is tube amp. Mot made a number of variations of these. They do make good repeaters. Just takes some work. One clue if it is a repeater and not a base station is the card cage usually has a Squelch Gate card. This controls rx to tx keying.

I am looking for some help figuring out what this is split, etc and how to make it into a repeater. First things first is that there is no power leads hooked up except for the one to the control board box. I can see where there are places for heavy cables from the power supply to the transmitter. Is there seperate power for the receiver or does that come from the ribbon cable? How can I get this thing to key up to see what the TX frequency is? If I find out the TX freq can I sweep the recv side with a freq generator to figure out where it opens up? Are these crystal controlled or can they be adjusted to get the right frequency pair?

[Repeater-Builder] Re: Another frequency grab.
Mike said: This sound like an un-necessary technical solution for non-existent problem. Unfortunately, this is not the case. Having had family involved in the medical profession (RN) I was told of several horror stories of objects being left in patients, in one case resulting in the death of the patient. HOWEVER, based on the description of the device's use in the application filed, I wonder why such a large chunk of spectrum is being requested. For such short-duration, enclosed use, I would think that 0.5Mc or possibly even less would be more than sufficient to accomplish their needs. If they were to be assigned a band, say from 909.5 to 910.0 Mc., I would think that that would more than meet the requirements for that type of application. I also believe that this type of argument would carry more weight in responses to the FCC. That said, even if they get what they are asking for, I find it hard to believe that this would produce much potential for interference given the fact that it would be most likely used in a concrete and steel building, the radiator would be highly inefficient and directional, interrogation times would be very brief and overall usage would not constitute prolonged periods of time. It's reassuring that people are keeping an eye on these things but this particular one does one raise much concern in my own mind.

He drafted loggers or other locals as operating help. And he never left a sponge or an instrument in a patient. This sound like an un-necessary technical solution for non-existent problem.

or to push to 52MHz for the amateur 6 meter band). Mike, Did I understand this correctly? The 42 to 50 split can be pushed to the 52Mc repeaters without modifying the front end? I have a U51LLT Motran that I would like to put on the 6m ham band, but digging into those front end coils has scared me off a bit (there's too darn many of them). Would be great if it could be pushed to 52Mc without mods. Also, someone on here mentioned the channel elements. My channel elements for that radio were lost when I moved to this house and I haven't been able to find any. If there are any spares floating around for the L transmitter and L receiver, either one or two channel, I'd sure like to buy them. The ones that were in there were TLN1022A and TLN1020A, but I'm told that the TLN1080 series will work also. If anyone has anything, please email with what you have and price.

The manual that covers it is 6881005E40, which is no longer in print. I am assuming that the model number tag actually represents the equipment inside. And Rich - that radio is NOT going to cover 30 to 50mhz. It's built for a subset of those frequencies, called a range or a split in Moto terminology. The 4 in 3400 indicates that you have a dual receiver unit, or at least the radio that was in the cabinet originally did. The low band Motracs came in three ranges: (1) 30-36mhz (which can be pushed to 28mhz for the 10 meter band) (2) 36-42MHz (pretty useless except as parts, or maybe for a Volunteer Fire Department that has channels there) (3) 42-50MHz (useful to Red Cross, which has a nationwide channel at 47.42Mhz, or to push to 52MHz for the amateur 6 meter band). It's not practical to try and range change a low band Motrac as you would have to modify (or rewind) some coils. Did it come with the Channel Elements? They are little blue or gold aluminum cans that plug into a cluster of 4 pins in the receiver or transmitter. The receiver had locations for 2, the transmitter for 4, and an option board added slots 3 and 4 to the receiver. Setting that unit up on channel, assuming you have the channel elements, is about $40-50 if you re-crystal the elements yourself, or more if you have the crystal house do it. And they you get to tune it up. Mike WA6ILQ
