My MSF5000 is a 900 MHz unit, so I'm not sure whether the connections would be the same or not... My thinking is that with the level of microprocessor control involved in this station, you'd probably get error codes up the ying-yang and not be able to test it without all parts properly connected/terminated.

RE: [Repeater-Builder] The emails we get at repeater-builder....
I made some comments on this subject in another email, and they weren't aimed at anyone who falls in the baseball card license category, but towards those who won't take the time to do a little preliminary research before asking a question. My comments weren't even aimed specifically towards this group, but others, especially those that are for a specific model of radio. This group is comprised of (in my opinion) the greatest collection of talent and expertise that you'd find most anywhere, and a lot can be learned by just reading the messages. My knowledge of repeaters is very limited so I seldom post here, but I do read most of the messages. On other groups, I've seen many questions posed by people who have obviously never opened the manual. So, to avoid falling into the baseball card category, just: 1. Read the manual! 2. Search the message base! (hint: you can see 98% of all questions asked by going back only two to three weeks) 3. Use Google! Then if you still can't find the answer, by all means ask!

[Repeater-Builder] Re: MSF-5000 RX1 shutting off w/TX ACT
Yes,I did have it set-up as in cabinet repeat and it would basically do the same thing. Key up on the input, tx comes up, no rx AF out, stay keyed up on the handheld and the hangtime drops and then cycles back up again and keeps doing that as long as I keep a qualified rx signal on the input. Very strange indeed. If I can't get things to work right with a new eprom set I'm thinking of using one of the RLC-MOT COR boards and hook it straight to the discrim out and use that to trigger the cor and provide gated audio. What a waste; a third party board with a motorola micor squelch gate circuit on it in a Motoriola repater. What's the world coming to? I guess I could read up on the squelch troublesooting guide and see if something is boogered up on the squelch gate circuitry. --- In Repeater-Builder@yahoogroups.com, Bob M. [EMAIL PROTECTED] wrote: Theoretically, you read the existing code plug, shut the system off, replace the two EPROMs, turn the station on, convert the code plug to System 3, then write it back to the station. Alternatively, you can start with a CONV3.DEF code plug, configure it, and write that to the station. I've done it a couple of times on UHF stations with no problems, however, others have had problems, although the station was already in deep doodoo before they attempted the upgrade and they couldn't read the old code plug or load in a new one before or after an upgrade. You'll probably also have to go back and set several EEPots after running in new firmware. For some reason, some of the most important ones default to 00. That's still very odd operation you're experiencing. It's as you say: almost as if the station thinks it's a half-duplex base station which cuts off the RX when you TX. I hope someone didn't bugger up the station by modifying it so it worked that way. I suppose an inverter wired in the right spot could somehow link TX ACT to RX ACT. It would be possible if you really wanted to do it bad enough, in which case new firmware or even a new code plug wouldn't fix it. Did you pull the SSCB and check for any foreign wires? Did you try setting it up as a stand-alone repeater and see if it has the same problem that way?

You aren't using PL/DPL or a connect tone, just carrier. There could be some SP code that's hanging around in the station; maybe it needed something in the expansion tray at one time to key the transmitter or keep the receiver going. The MCS option would decode multiple PL/DPL, then force various bits in the MuxBux. That was the only connection available to the station, the same way the switches operate on the DMP. Maybe that option is still lingering in the code plug. I had one station that would key up as a repeater, but 1/2 second later the transmitter would then shut down. I never could find any setting for it, but when I put in a new conventional code plug, it started acting normally again. You can't modify every field in every configuration, so start with CONV.DEF, populate it as necessary, and write that to the station. It might get you running again. Also, you're using very old firmware and there could be bugs in it. Replacing it with version 5 would be a last resort.

I have been round and round with all kinds of config changes and regardless of what I do everytimne the PTT is triggered (via MRTI or LOCAL) and the TX comes up the RX1 ACT light goes out on the DMP. The RXUNSQ RPT UNSQ stay lit however. As soon as the tx goes off the RXACT comes back up and audio is there. Acts like a base on same T/R freq with the rx switching out from tx going active. It is programmed for repeater disable, FULL duplex, RX PL=CSQ and triggered by Audio Squelch. I need to drive 2 external PL boards so they listen to the discrim out (TP3) into the external controller. I can force the bits via DMP for RX1 ACT to stay on and that will work (RX wide open CSQ) except if it gets powered down and then it reverts to where it was. any ideas? Thx.

RE: [Repeater-Builder] Re: Motorola MSF 5000 power connections?
Dave, You might want to watch eBay for the PA, Dave. [Search for both MSF5000 and MSF1 - the European version - especially if you're looking at the European eBay site(s)...] They pop up from time to time... or ask here - maybe someone has one that is surplus to their needs. Shipping across the pond might be a bit prohibitive, though. They're not lightweight, for certain! But like I said, I think there is a feedback loop (for lack of a better description) in the MSF5000 station that monitors both FWD and REF currents (or voltages) from the PA, so the station can tell if it's making too much power, etc. Without the PA connected the processor doesn't see those signals and gives an error code - or two or three... :-) I'm learning more and more about this station every day, but I have ...miles to go before I sleep.

Skip: Thanks for the antique stove tip. I had searched mica insulator and just found transistor insulators. Mica sheets arrived Friday, and I got the TX fired up today. The amp appears to be very comfortable in the area of 200-250 Watt output. I got it up to 300W at one point but it didn't seem to like that as well. We always ran it at about 200W before when it was in operation. Now I just need to schedule some help to load it in the pickup and then take the 60 mile drive to the repeater site.
