Re: [Repeater-Builder] Can a Master 3 narroband
Hello Jim I note your message about narrowbanding and the comment about the MSR2000. I have seen no info on doing so but it seems to me that the MSR200 could be narrowbanded. The MSR is very similar to the Mitrek and it can be narrowbanded by using a kit by a company that slips my mind. Therefore I feel narrowbanding would be possible. I will be attempting this in six months or so. 73 de Tom Manning, AF4UG - Original Message - From: Jim in Waco WB5OXQ To: Repeater-Builder@yahoogroups.com Sent: Friday, August 27, 2010 10:07 AM Subject: [Repeater-Builder] Can a Master 3 narroband I have a uhf master 4 that has been used for years as a paging exciter.

[Repeater-Builder] Re: Intermod Calculation
We had a pager spur problem with our repeater (no pl). The problem would come and go. We determined it happened mostly with time of day (outside temperature). Sometime it was just a short 1 second event and sometimes it would hold for a bit more (maybe 2 -5 sec). We setup a satellite multimode radio (actually dial in the frequency with widest bandwidth setting) and monitored the repeater input with a tape recorder and vox. We did this to capture the audio so we could listen to characteristics and THE CW CALLSIGN. We captured enough of the callsign that we were able to indentify the whole call (and freq) from the FCC database. With that, we were able to monitor the repeater and the pager for hits. Yes, it did hit some times and not others. The reason was, it was caused by an unstable spur that drifted up and down the ham band with temperature and the amount of pager traffic. It was also hitting other repeaters as it drifted but most of the other repeaters had pl. There was a chain of pagers using the same freq and callsign and we had to figure out which tower it was. We used a beam antenna and chased the spur up/down the band until we were able to get a definite direction. The next step as to visit the site AREA with an HT and just scan the ham repeater input freqs during the likely time of day. Bingo, the spur was loud and clear!. Of course the pager owner was in denial but being a pest for a couple of weeks got the problem removed. They claim it was a spur in the final PA that had been serviced just at the time the problem started. They replaced the PA. Hope this story helps. Tom

Re: [Repeater-Builder] DB224A new harness

Me: 'Just this fifty. You don't take $2 bills? Why? Server: 'I don't know.' Me: 'See here where it says legal tender?' Server: 'Yeah.' Me: 'So, why won't you take it?' Server: 'Well, hang on a sec.' He goes back to his manager, who has been watching me like I'm a shoplifter, and says to him, 'He says I have to take it.' Manager: 'Doesn't he have anything else?' Server: 'Yeah, a fifty. I'll get it and you can open the safe and get change. Manager: 'I'm not opening the safe with him in here.' Server: 'What should I do?' Manager: 'Tell him to come back later when he has real money.' Server: 'I can't tell him that! You tell him.' Manager: 'Just tell him.' Server: 'No way! This is weird. I'm going in back. The manager approaches me and says, 'I'm sorry, but we don't take big bills this time of night.' Me: 'It's only seven o'clock! Well then, here's a two dollar bill.' Manager: 'We don't take those, either.' Me: 'Why not?' Manager: 'I think you know why.' Me: 'No really, tell me why.' Manager 'Please leave before I call mall security.' Me: 'Excuse me?' Manager: 'Please leave before I call mall security.' Me: 'What on earth for?' Manager: 'Please, sir..' Me: 'Uh, go ahead, call them.' Manager: 'Would you please just leave?' Me: 'No.' Manager: 'Fine -- have it your way then.' Me: 'Hey, that's Burger King, isn't it?' At this point, he backs away from me and calls mall security on the phone around the corner. I have two people staring at me from the dining area, and I begin laughing out loud, just for effect. A few minutes later this 45-year-oldish guy comes in. Guard: 'Yeah, Mike, what's up?' Manager (whispering): 'This guy is trying to give me some (pause) funny money.' Guard: 'No kidding! What?' Manager: 'Get this. A two dollar bill.' Guard (incredulous): 'Why would a guy fake a two dollar bill?' Manager: 'I don't know. He's kinda weird. He says the only other thing he has is a fifty.' Guard: 'Oh, so the fifty's fake!' Manager: 'No, the two dollar bill is.' Guard: 'Why would he fake a two dollar bill?' Manager : 'I don't know! Can you talk to him, and get him out of here?' Guard: 'Yeah.' Security Guard walks over to me and.. Guard: 'Mike here tells me you have some fake bills you're trying to use.' Me: 'Uh, no.' Guard: 'Lemme see 'em.' Me: 'Why?' Guard: 'Do you want me to get the cops in here?' At this point I am ready to say, ' Sure, please!' but I want to eat, so I say, 'I'm just trying to buy a burrito and pay for it with this two dollar bill. I put the bill up near his face, and he flinches like I'm taking a swing at him. He takes the bill, turns it over a few times in his hands, and he says, 'Hey, Mike, what's wrong with this bill?' Manager: 'It's fake.' Guard: 'It doesn't look fake to me.' Manager: 'But it's a two dollar bill.' Guard: 'Yeah? ' Manager: 'Well, there's no such thing, is there?' The security guard and I both look at him like he's an idiot and it dawns on the guy that he has no clue and is an idiot. So, it turns out that my burrito was free, and he threw in a small drink and some of those cinnamon thingies, too.

First thing I tested was the reference voltage and lo and behold it was wandering around (light bulb above head begins to glow!). Close inspection of the ref voltage components revealed a dark discoloration of the board and a general corroded look to the solder connections. Looks very much like cold solder joints. The rest of the board connections are all shiny. (bulb is getting brighter) Also the tinning on some of the PC traces was etched down to copper. A few minutes work with an acid brush and some alcohol cleaned up the gunk on the board and the joints were all touched up with a soldering iron. (Bulb fully on!) It has been running on the bench for 5 hours and the reference voltage hasn't budged from 6.5v !! I will install the card back in the power supply this week and see if our voltage problem goes away, and it carries the repeater load. Interestingly enough our initial indications of a problem was when the repeater would drop off the air . We thought the problem was with the PA, since we could still see some drive coming out of the exciter. Eventually it completely failed, but not until after we replaced the PA only to see the same problem come back. Oh well, we now have a spare PA! As the NTSB would put it: Probable Cause - corrosion of solder connections due to caustic substance. To put it plainly - mouse droppings/pee! We had the same thing happen to an RC-850 controller a few years ago that nearly killed the board. The repeater is in an unheated building in a field away from other structures (it is a microwave tower that the Navy lets us use), so the mice seem to like the warmth. Next project is to make a mouse shield for the repeater box! I'll let you know how it turns out.

[Repeater-Builder] MSR2000 Power Supply part needed
Our club's repeater power supply (TPN-1191A) has bitten the dust and we have traced the problem to the Aux regulator board (84D82110N03, or 05 or 02). The 14 v regulator has decided that 8.5 and wandering is it's job! Anyone have a spare card in their collection that they would be willing to part with? Tom/W4OKW

Hello W3ML, I've been following this thread over the weekend and I think the issue has been addressed. I would check the antenna and related connectors.

Re: [Repeater-Builder] Re: Radio for repeater use Response to Tom's comments
Well then, that's what everyone on this group is here for. All you have to do is ask, and you've done that. All the advice tonight is valid, so now you need to make some measurements. You definitely need an iso-tee, and good watt meter, i.e., Bird or Telewave, and a service monitor with at least a spectrum analyser would be a good start. Read the RB page and follow the suggestions. We actually had a couple of Mastr II mobiles rigged as repeaters, but we didn't de-rate the PA's. They saw heavy use with zero problems for over ten years before we replaced them with stations. Of course the tower building was a constant 74oF in the Texas sun and the A/C ran most of the winter. It's a shame there's not another antenna on the tower you could borrow for a few minutes. thp W3ML wrote: Thanks Tom, Getting help around here is the hard part.

[Repeater-Builder] RE: OT: Tape
In case you weren't able to find a source yet for the silicon tape try: www.rescuetape.com http://www.rescuetape.com/ They market it as an emergency tape for hoses, leaks, etc. but it's the same stuff and cheaper than paying for name brand prices from the antenna companies. It's still more expensive than electrical tape but IMHO it's worth it. It comes in different colors and widths as well. I started using the silicone tape several years ago and haven't looked back. It seals (vulcanizes) to itself, conforms to uneven spaces and is water tight with no gooey mess but you've probably gathered that from the comments here. Hope this helps. Tom, N6MVT
[Repeater-Builder] Tram 1481 Dual Band UHF/VHF Antenna
JIM KA2AJH, I use the TRAM 1480 (also Workman version) in several installations and they all work well. I have not had any problems or failures. The 1481 has additional collinear sections on top (making it about 6 ft taller). The TRAM and WORKMAN antennas are ELECTRICALLY similar to DIAMOND and COMET (I've had some completely apart). There are some mechanical differences which might make the D and C brands a little more durable in severe weather areas. I don't think they are worth the extra price. Now, they all are DC ground but not in the way we all think when compared to a J Pole. The antenna element is internally grounded through the coil in the base but capacitively coupled to the coax center conductor. So, if you look for a DC connection between center conductor and ground, you will think it is open circuit (but is not). Now, all of these very tall antennas tend to be very whippy. With the very low launch angle (particularly on 440) any strong wind will cause the signal strength to vary considerably with the wind. You might consider taking it completely apart (easy job) and examining for water (moisture) and any evidence of bad solder, broken connections or burn marks from lightning discharge. I have rebuilt a DIAMOND X500 that failed after many years. The problem was that the fiberglass wore thin and allowed moist air to condense onto the internal foam rattle insulators. They all seem to use common pieces of soft packing foam that acts like a small sponge. Replacing these and repainting the fiberglass (white or light gray PLASTIC spray paint) fixed the problem. The point is, all 4 brands are at risk of the same long term problem. Tom

On a somewhat related notes...I had to do some research on the rare (and not currently made) down tilt models from db products.

Not complete or easy to read (originally faxed) but it helps to determine if you might have a 4 or 9 degree downtilt harness and other related parts measurements. If someone is in need of them I can either e-mail or perhaps post on this site. Also, I have seen some of the dipoles get modified with short stainless machine screws+nuts drilled through the top bottom of the dipole elements, to help get the Return Loss even better at lower freqs. Not sure what, if any, skewed pattern is introduced by doing the machine screw mod or not. Quite often it's hard to tell any changes in the field unless it is very drastic. Tom

More specifically, I have several XPR-8300's that are running in analog mode. They are externally controlled by S-Com 7330 controllers (although I don't think that matters much). All the XPR's seem to have some strange audio glitch that causes the TX audio to distort for aprox 1 sec. This usually happens with nearly all key ups and mostly just once sometime while the carrier is up until the repeater drops and the cycle starts all over again. It is not repeatable as far as at what point it starts doing it after first being keyed although it does seem to happen later and later while the carrier is up with more activity (as if something was warming up and changing the timing interval). It is on the TX side of the repeater and not in the rx side. It happens whether using squelched/filtered audio or unsquelched/flat audio. I have tried different gain level settings with no change. When using it as a stand alone repeater (internal/in cabinet repeat) it has no such problem. Has anyone seen, heard of or come across any such issues? They are running slightly older firmware like 3.31 (or some combination of those digits). I have not upgraded yet to see if anything was fixed. Motorola was of no use with this matter and several other issues I raised with them (~6-8 months ago) regarding operation and tuning. They basically look at this as a digital repeater and the analog side is essentialy a freebie so... I think you know. Thanks in advance for any input. Tom

[Repeater-Builder] Six Meter Repeater Noise Issues
Several months ago I put a six meter machine on the air in my area. It is a GE Master Pro tuned for 52.810 out and 51.110 in. One of the things still nagging me is some sort of desense or RF phase noise, let me explain. After tuning up the duplexers into a dummy load and running some tests I experienced no desense all the way down to about .15uV. I moved the dummy load to the end of the transmission line just to be sure and again the same results. When I put the antenna in line and run the same tests this is what occurs. When I key the transmitter and set the output of the signal generator from a starting point of say 100 uV I hear what sounds like phase noise or just plain static just slightly in the background. As I bring the signal generator output down the background noise gets louder but it never wipes out or overloads the receiver altogether as I can still hear the generator and the background noise and this is down to the same squelch threshold I get when on the dummy load. I am hesitant to call this desense as say when one of the duplexer cavities isn't tuned correctly. Then it is obvious because the transmitter totally wipes out the signal I am feeding it from the signal generator. I thought perhaps the preamp was the culprit so I took it out of line but sill experience the same issue. I am thinking that possibly the repeater output from the antenna is getting back into the repeater cabinet? I took a handheld scanner and set it on the same frequency as the receiver and connected directly to the rx port on the duplexer and can hear the noise there as well. I do hear a slight buzzing in the audio of the receiver almost like 60hz whenever I key the transmitter with the squelch wide open and no input signal present using the antenna. I don't hear it when using the dummy load though. I would like to think that the duplexer is tuned correctly or fairly close as there isn't any desense when terminated into a load. The last thing there is a single phase 7200 volt primary line servicing our neighborhood probably less than 100 feet from our house that I wonder is the culprit. I don't hear any arcing or power line noise with just the receiver squelch open but maybe when I transmit there is some mixing going on? Thank You Tom Elmore KA1NVZ Anchorage, Alaska
Re: [Repeater-Builder] Converting a Range 2 VHF Mitrek to Range 1 (WAS: Holiday Special...)
GOOD AFTERNOON kEVIN This last response is my thinking about the Mitrek and is why I asked the question earlier. If the Mitrek coils are the same as the Micor coils what factor would prohibit this being done. There is considerable work to change the coils but if the Micor coils are the same nothing would prohit a person from doing this. As I said earlier I know for a fact that the mid band receivers will not tune lower than 146 Mhz. Perhaps an occasional one would be found that would tune to 144.0 Mhz but not all.

Re: [Repeater-Builder] Holiday Special - MICOR 2 meter receiver conversion from W3KKC
Hello Kevin Thanks for your reply. Your statement is correct in that all of the receiver coils begin to tune at the bottom of their travel. I have even tuned two or three too far and they dropped out with the resulting work to retrieve the screws. When tuned as best I can for sens the s/n ratio is 1+uv at 12db sinad. The original frequency sens was less than 1uv-usually about .3uv for 12db sinad. Replacing the coils are about the only solution I know of for these high split VHF units. I have in the past replaced two sets of receiver coils with Motorola coils and found I have good sensitivity as before modification. The transmitters all tuned well on this split and gave rated or more power output. The Mitrek coils looked very much like the Micor coils. I have replaced probably a half dozen Micor receiver coils proscured from Motorola in the past 20 or so years. Thanks. 73 de Tom Manning, AF4UG - Original Message - From: Kevin Custer To: Repeater-Builder@yahoogroups.com Sent: Thursday, December 18, 2008 10:02 PM Subject: Re: [Repeater-Builder] Holiday Special - MICOR 2 meter receiver conversion from W3KKC Tom, You say you find similar operation on 4 or 5 units. By that do you mean they won't make book specification on any frequency below 146 MHz? If that is the case, I would believe something is wrong. I have seen many Mitrek high-band receivers that were tuned for 144 something and had very good sensitivity. Let me ask you this When tuned at 144.89, is the front-end tuning all one ended, or is there adjustment to spare? In other words, can you tune the front-end without the fear of the tuning screws falling into the casting? If you have room left to go lower in frequency, then the front-end is not the problem, and you'll need to look elsewhere for the lack of sensitivity. Another question - do these 4 or 5 units tune and make book spec sensitivity on their original high-band channel? I guess what I'm saying is I doubt the problem is the front-end helical resonators, but if there is a need for a conversion I'm not opposed to looking into making a modification available, if it is needed. If there are others on the list that have had good luck with the Mitrek on frequencies below 146 MHz, please chime in and let us know what you have and how well it works.

To possibly broaden your options, this might help. The original IMTS dial control head was designed by Secode in San Francisco to phone company specs. The control heads and cables will plug directly in to any manufacturer's IMTS RF drawer. Later versions did have some variations on the control head, appearance wise, but, electrically, they still were direct plug in to all of the units. Otherwise, I can't help; I threw out the last one I had, a GE Mastr Pro, a couple of years ago. Seems to me I read some posts about one of those not too long ago on one of these sites.

Observations, suggestions, and your crazy are appreciated! Unfortunately I have to add myself to the list of naysayers but to answer as you requested: Basically the question is: at a 2 mhz seperation (odd split) on VHF can one get away without using duplexers (cans), utilizing separate rx/tx antenna's, spaced about 20 ft apart! Without desense or other issues NO. Inadequate physical separation, inadequate frequency separation, especially using the equipment described. Being such a remote area, and the nearest 2 meter repeater is well over 50 miles away, and nowhere near these frequencies - 145.500 rx/147.500 out using a tone of 179.9, I do not see any interference issues there! As you suggest, the likelihood of interference is small but NOT nonexistent. If it were me, I think I'd have a receiver (on carrier squelch) monitoring your repeater output just for the purpose of CYA. Overkill? Maybe, but as the movie actor asked, Do you feel lucky today? At least you could answer truthfully that the frequency was monitored. --- In Repeater-Builder@yahoogroups.com, Louis [EMAIL PROTECTED] wrote: I apologize if this has been addressed previously, or even close!

RE: [Repeater-Builder] LMR-400 Cable
Here is the latest. I terminated the cable at the antenna with a dummy load and no desense. I hooked back up to the antenna and if listen to the receiver with the squelch open I hear a buzz in the background of the receiver white noise audio in addition to desense which doesn't show up when terminated. Checking the swr I have less than 1/2 watt reflected with about 80 forward. The offset for this receiver is 1.7 Mhz by the way. If I take a 1/4 wave mag mount antenna that I have sitting on top of the duplexer cabinet and plug it directly into the receiver I hear no buzz or desense. This tells me something is going on with the antenna and coming back the line. Is it time to put in some hardline?

The duplexer may be tuned for a 50 resistive ohm load, but the antenna system is presenting some other impedance/reactance.

[Repeater-Builder] 6 Meter Repeater Desense issues.
First of all let me thank everyone that answered my questions about LMR-400 cable and the desense issues I have been having. So far tests right up to the antenna with a dummy load have shown no desense so to me that leaves the antenna. After some discussion with a Diamond representative who didn't have a lot of technical background this is what I have learned. The model DP-GH62 appears to cover the 6 meter band in two segments. 50 to 51.5 and 52 to 54 Mhz. There is a 9.5 pf cap across a coil at the base and with the cap in place it is supposed to operate from 50.to 51.5 and removing the cap moves it up to 52 to 54. My repeater frequencies are 52.810 out and 51.110 in. So I need to either move my input frequency up or so If I play with the value of the cap say 12 to 25 pf and make the antenna resonate somewhere from 51 to 53 Mhz? Thank You Tom Elmore KA1NVZ Anchorage, Alaska
[Repeater-Builder] LMR-400 Cable
I recently put a six meter repeater (52.810/51.110) on the air here in Anchorage, Alaska. I am feeding it with about 60 feet of LMR-400 cable and am experiencing quite a bit of desense. I did a search for LMR-400 in duplex operation and came across several posts from users of this list and decided to sign up and investigate some more. I am running a GE Master Pro at 100 watts into a 8 cavity Sinclair duplexer. The antenna is a Diamond co-linear mounted about 35 feet above ground at the present time. I live on a hill here in town and currently have the repeater mounted at my home qth. When I terminate the duplexer into a dummy load and look at it with the spectrum analyzer it performs very well with no desense. Connecting up the antenna is another story altogether. I have been pulling my hair out over this one thinking it must be a duplexer problem. Originally I fed the antenna with RG-213 which I know is not the best choice for repeater use but it is what I had handy at the time. I was getting desense with the RG-213 so I switched to the LMR-400 since I had a roll someone had given me. I actually think I had slightly less desense with the RG-213. Is the 400 really not that suitable for duplex operation even at 6 meters? What would be a good alternate choice ? Thank You Tom Elmore KA1NVZ Anchorage, Alaska

There isn't going to be much warning before that RF output module self-destructs.

Sadly it seems the Comet/Diamond type antennas are some that a lot of people are using, and commercial quality options are few. For our repeater, which is on a mountain on the West side of the city, we used a custom-built 120 degree panel reflector. Sending the extra RF of an omnidirectional antenna back into the mountains, turned out to be a problem for our analog 1.2 machine years ago, so we avoided it and went straight to something with some gain toward town on the D-STAR system. DV (voice) on D-STAR 1.2 acts similar to any other analog 1.2 GHz repeater. DD (high speed data) being 100 KHz wide, requires more gain to go the same distance. Gain antennas are often necessary for good links on DD... a 10W radio, 100 KHz wide, isn't much signal left to work with a the far end. There is at least one ham running around saying he's bumped his ID-1 to 20W with no ill effects by finding the power setting pot inside and cranking it wide open. Not sure I'd do that, but just relaying the info. I'd want to look at it on a spectrum analyzer and also keep a very close eye on it for heat load if I were going to mess with the power setting in the rig. But his reports are that his ID-1 is surviving the abuse, just fine so far. Nate WY0X
[Repeater-Builder] Re: Curious Situation
Assuming that your duplexer is a BP/BR type, it's true, setting the pass pretty close is not too difficult using an incoming signal. How did you set the reject side? Not that it can't be done (at least, close) but I'm sure your investment in time is several times that that the shop spent setting it (hopefully) correctly. When I first started messing with two way, I obviously didn't have much equipment to work with. I usually was able to make things work but when I got into the business, I quickly found that I didn't have time to mess with things long enough to make them work right. All of a sudden the test equipment became a real bargain and I KNEW that what I turned out was right.

Having tuned these merely to incoming signals before, peaking them while the repeater is still in a testing mode, seemed to return decent results but the tune-up was thought to be a better idea. Not so.. Today's tune-up hardly was worth the wait or the price based on the results. While a 5 watt HT 10 miles away could work the repeater, now 25 watts from a roof top antenna is now just about full quieting. Fifteen watts does not make the repeater through the same roof top ground plane. Does logic dictate that we go back to seat of the pants tuning and cast fate to the wind? - Mike

When I first started building repeaters in the late 1980's early 1990's, I had to figure out everything myself or hope that someone in my handful of technical oriented friends would know the answer. For example; I remember in about 1993 trying to set up my 2 meter repeater to encode 2 different PL tones at the same time. I eventually figured out how to do it, but I spent a lot of time figuring it out. Today, we just ask that question on this forum and someone can explain how to make it work.

A device that actually draws 20 amperes at 120 VAC must be plugged into an outlet and branch circuit rated at 30 amperes.

Most repeaters and high-power PAs have optional connections to enable operation on 208 or 240 VAC. Keep in mind that there is no such voltage as 220 although that obsolete figure is still in common usage. The nominal single-phase voltage supplied to residences is 120/240 VAC, while the electrical supply to light commercial, apartment complexes, and condos is usually 120/208 VAC derived from two phases of a three-phase distribution system.

However, circuits can be loaded 100% as long as it is not a continuous load (operated for more than 4 hours).

You can see that the vacuum is designed for 120 volt operation (plus or minus) and they tell you the maximum current, therefore you have an approximate volt-amp rating for the motor. Assuming the power factor of the small motors is fairly similar (I don't know that but I would guess they are) you now have an APPROXIMATION of the amount of work the motor can do. In the case of the 13.8 volts, no other information is given. You therefore have NO idea of the input power of the transmitter, etc. Of course, in the case of the vacuum, impeller design, housing design, air flow routing, and numerous other factors come in to play but, short of an industry standard rating, it's better than nothing.

It didn't take this admission to realize that the ad was phony. The laws of physics clearly show that a few hundred milliwatts (or even a few watts) from a cellphone, or even a dozen cellphones, for that matter, cannot produce enough heat to vaporize the water in a kernel of popcorn. Add to that the fact that, when several phones are used, who's to say that the signals are all in phase, therefore additive.

I wonder how this happened. I am sure the supply is UL listed (no such thing as US approved) so looks like something got over looked or a change occured at RS manufacturing. The thing was made in CHINA!!! Need I say more? They just got through killing hundreds of our pets, so far this is minor! I don't buy ANYTHING made in China since that happened. I recently walked out of the local dollar store because the product I had intended to buy was made in China; that is now a way of life for me.

OT (sorta)...there is the possibility that the unit may be plugged into an improperly-wired receptacle- which happens often when do-it-yourselfers change out a receptacle. Just a heads-up on the assumption that a professionally wired home is safe. When I bought the house I'm living in now, one of the selling points was that the old knob-and-tube wiring had been replaced with new Romax and a new 125 amp breaker panel (by a professional electrician). All of the outlets were the 3-wire type so I ASS-UMED that all was well and good. The house even passed a buyer's inspection as part of the sale. Well, things were not all as they appeared. After getting smacked a couple of times on the bench, when I knew I shouldn't have, I started looking. Although all of the outlets in the house were the 3-wire type, only the ones in the kitchen (not even the bathroom) had the third wire ground actually connected. All of the others were wired with 2-wire Romax and NO ground. Now, if that isn't a booby trap, I don't know what is. So, unlike me, don't assume anything. Buy a cheap line tester and check every outlet you have in the house. It may save your skin!

Nevertheless, I see inadequate and sometimes dangerous electrical installations almost on a daily basis... Another war story that goes with your comment. Shortly after I retired, I took a job with a company that was located in a former International Harvester building doing general maintenance type work. Part of that job included running over the rough concrete floors with a cleaning machine. In one unused part of the building, I saw a length of several fairly heavy wires lying on the floor, near a puddle of water (the roof leaked in that section of the building). I thought I'd just coil them up and hang them on a spike on the wall near where they originated. I picked up the wires and started to coil them up and as I straightened them out I hit the end of the wires and they soundly hit me back with one of the most painful shocks I can recall receiving. It turned out that those lines were part of a 440 volt, three phase line that was never turned off when the equipment was moved out of the area. Once again, I was very lucky in that the only injury was one gigantic scare over what might have happened. Another lesson, never ASS-ume that a line is dead until you confirm it. Had my other hand been grounded, I probably wouldn't be telling this story now.

I've seen many a blown reverse protection diode from just the same installation. You can't go wrong with the inverter. Also, the added load on the single 12 volt battery of a 2-12 volt series can cause enough imbalance to cause charger problems and battery boiling of one of the batteries. my 2 1/2 cents thp Steve Kometz wrote: You can cheat and run off one of the 12 v batteries.

[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?

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?

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.
