Re: [Repeater-Builder] Astron RS50 Power Supply
Those older? units actually have an out of phase tap on the Xfmr, 10v? or somethin! forget what color the leads are, can check. Believe it or not I have brought several of them back to life by just soaking the transformer in varnish and letting it dry of course! That feedback winding oscillates and vibrates the xfmr resulting in non(good) stabilization of the xfmr, vibrates for so long, actually loosen's the windings Now everyone is gonna say i am nuts! For the cost of a can of varnish, think you actually have to use polyurethane today, just try it! beats the cost of a new supply! And of course change all eletrolytics if it is the one wit h a gaint amount of 2N3055 (mpn)or equiv on the outs than i am totally correct!

This may not cause a problem for some systems, but is certainly not a recommended practice where DC power returns and signal common conductors are at similar potentials. It is a long-established practice in the power, broadcast, and communications industries that there should be only one connection where all signal and power grounds are brought together. For residential and commercial wiring, the National Electrical Code (NFPA 70) calls this point the service. The Code is very explicit that the service is where CATV coaxial shields, telephone line protectors, and the power neutral are joined. Likewise, most cellular and LMR stations follow such guidelines as the Motorola R56 Manual, which specifies a ground window where station grounds, power grounds, and feedline grounds are made common. To establish additional grounds at DC power supply returns is almost certain to create ground loops that will interfere with sensitive equipment and circuits. A case in point: My 6m repeater controller would lock up periodically, requiring a 60-mile round trip to the mountaintop site to reset the system. When these lockups occurred, both the primary receiver and the link receiver were deaf, and I lost control of the repeater. The cause was not apparent, since the lockups occurred in clear, mild weather with no obvious causes. On a hunch, I tested the Astron RS-35M power supply and discovered that the negative output terminal was jumpered to the chassis. I removed that jumper, and the problem went away-forever. My guess is that a surge from a nearby air-conditioning system was coupled into the grounding system, and the resulting spike on the DC return for the controller caused it to be corrupted. Another repeater that used an Astron power supply had a low-level 60 Hz hum on the audio that was audible only at base stations, which used larger speakers than portables or mobiles. After I did some head-scratching, I surmised that the hum was not a ripple from the power supply, since that would be 120 Hz in a power supply with a full-wave rectifier. This repeater had a gel-cell battery floating on the power supply output (with a Schottky blocking diode, of course), and I noticed that the hum stayed when I turned off the power supply. However, the hum went away when I unplugged the power supply. Aha! Once I removed the internal jumper connecting the negative terminal lug to the chassis, all was well. Astron is not consistent with these jumpers; some models of power supplies- both linear and switching- have them, but not all. IMHO, the station designer should decide where and how the system grounds should be connected, and not the manufacturer of a power supply. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Leroy A.

Re: [Repeater-Builder] What have I got?
Not really an expert on that unit! General rule of thumb: when you have an existing exciter, the power amp (final) input is usually around 1/4 W (250mW) or higher. Most GE junk is 1/2 watt in. you cant go wrong with trying 250mw. If it's not enough just put the bird (wattmeter) on the final and jack it to spec. Also if you could tell me how many actual boards, and the # of final xstrs not part # , just how many are in there i can prob give you a better answer on what minimun i would push it with! SORRY i can't help you much more than that! Been in the biz a lot of years and when we aer'nt sure we just start smalll and go from there. zero chance of burnin somethin up!

Re: [Repeater-Builder] MOVs for power supply primary
I agree fully with NOT using Radio Shack low quality run-off manufacturer seconds. Use NTE 140V. The trick is you need to use THREE. One across the hot and neutral. one from hot to ground and one from neutral to ground. MOV's are a funny dog they do not usually short but degrade very quickly depending on number of incoming spikes they suppress. Used them alot to supress the reverse EMF in electromagnetic locking devices, 8+ H, yes henrys! , not micro or milli. suggest replacing annually.

I have a ICE surge suppressor on in front as well but thought I would put more inside the supply for back up. I'm not that big of a fan of MOV's, but if you really feel the need to add them across the transformer primary, as long the input to the power supply is properly fused, whatever floats your boat. Also, are the MOVs that radio shack sell any good. Rated at 130VAC. Any body used them... I'm not sure that there's anything that Radio Shack sells any more that's any good, is there? Seriously, I'd buy Last question: when MOVs fail or take a surge do they fail in a shorted condition taking out the fuse till the MOV can be replaced, or do they blow or fail open leaving the supply working. My experience that small MOV's fail in one of two ways. Either they fail shorted, quite often with no outward visible signs, or they fail open catastrophically as a zillion pieces of shrapnel that can cause damage to nearby components, wiring, people, livestock, etc.. Another downside to MOV's is that after they've successfully quenched an over-voltage event of any significant energy, their clamping voltage changes. So, you may end up with less and less protection over time. Good surge arrestors/TVSS's are expensive, and like most things in life, you get what you pay for. If your site has a good surge arrestor at the service entrance, you really shouldn't need anything extra. --- Jeff WN3A

RE: [Repeater-Builder] Off-Topic: Shop liability insurance
1) As we all know you need at least liability insurance on your business. 2) Since most manufacturers hold themselves not responsible for ANYTHING (incidental damage) other than replacement or repair during the warranty period a customer does have the legal right to TRY to contract you to do so.

Re: [Repeater-Builder] Off-Topic: Shop liability insurance
I think they are going to be extremly short of suppliers very soon! As far as average liability insurance is concerned it varies on the scope of your business practice. I am required to have a 2 mill liability policy on a tower space I rent. costs me about $100 a month. Needless to say with the economy and nextel, I will be shutting that site down shortly if things don't pick up. It is far cheaper to own you own tower site and contract out installs and service with a capitation It seems to be working as the small shops need the extra install and service, in turn I just sit back and collect rental and of course just service my tower. --- On Wed, 5/19/10, Scott Zimmerman n3...@repeater-builder.com wrote: From: Scott Zimmerman n3...@repeater-builder.com Subject: Re: [Repeater-Builder] Off-Topic: Shop liability insurance To: Repeater-Builder@yahoogroups.com Date: Wednesday, May 19, 2010, 5:42 PM Well... They claim they want product liability insurance for any products received on property. Not just installed, but SOLD!! I talked with one of the purchasing agents and they said they can no longer go out and buy a box of bolts at the local hardware store and use those in the manufacturing process since the vendor of those bolts won't insure them. I think they are trying to limit THEIR liability by being able to pass the blame onto their vendors. Quite frankly I don't see how a portable radio could be a liability issue, but I'm a technician, not a lawyer. At any rate, I was just trying to find out what the average sole proprietor pays for liability insurance.

Re: [Repeater-Builder] GE Rangr 150 - garbled audio when squelch tones are on
It is deffinately an electrolytic. look for a radial type with a slightly convex top I forget exactly where it is, been a while since I worked on those. When an electrolytic is going bad, or is bad, one sign is the swelling on the top. they usually swell just before they short. Test with a good DVM on the continuity range. it should beep until the cap charges, reversing the leads will make it beep until it discharges. (usually on a value of 4.7uF or more) continous tone means it is shorted. compare time of charge/ discharge to a known good cap or of course use capacitance meter if you have one. look in the discriminator line from the receive through the tone circuit itself. Also seen same with just bad solder joints. --- On Mon, 5/17/10, tec1122000 t...@teccs.biz wrote: From: tec1122000 t...@teccs.biz Subject: [Repeater-Builder] GE Rangr 150 - garbled audio when squelch tones are on To: Repeater-Builder@yahoogroups.com Date: Monday, May 17, 2010, 12:04 PM I own 4 GE Rangr 150s. 2 of the 40 watt and 2 of the 110 watt. They transmit and receive beautifully without the Call Guard tones turned on. The deviation is a little low and won't allow me to get full 4.75 kHz deviation, but the audio quality is perfect. When I turn on the Call Guard tone to use a repeater, there is a bunch of noise added to the voice audio. I am thinking that if I have 4 radios doing this, then someone else must have seen this problem before and hopefully has some answers. This radio doesn't have a separate tone board as some evidently do. The tones are created in the CPU and sent to the audio circuitry on the WALSH BIT lines from the CPU. Has anyone seen this before? I have adjusted the deviation pots (one for the PLL, one for the exciter) and still can't get the deviation up to spec. I am getting about 2.75kHz. I have the manual and have studied it thoroughly. My guess here is that I have a failing component such as a capacitor that is reducing my audio. Just wanted to see if anyone else has had this problem with these old radios.
Re: [Repeater-Builder] Feedback on Marconi 2955B RF Test Set
I have a 2955A I use on the bench. It took some time to get used too but is a very stable unit. I find though that I do miss the old analog meters. Once you feel comfortable with the control layout it's not so bad to operate. I will warn you the hybrid circuit packs inside, that do fail, are getting harder to come by. Overall it is a fine unit. I also have a CT 3000B for backup yet i still miss the convenience of the good old analog meter staring me right in the face. I wish I had kept my old CE-50 but hey, thats progress. I don't care what anyone says. Never key into a service monitor unless you have to. Even though they are designed to do so, you will find a day you will be sorry , even though you did it correctly.(Murphys Law) Use the Bird whenever possible. It will save a lot of headaches in the long run. Especially if you don't have deep pockets for replacement parts. Not trying to discourage you as they are great units. I find the older rigs more appealing, showing my age I guess :-) Enjoy your new Macaroni they are nice units! --- On Mon, 5/10/10, Tedd Doda la...@sentex.net wrote: From: Tedd Doda la...@sentex.net Subject: [Repeater-Builder] Feedback on Marconi 2955B RF Test Set To: Repeater-Builder@yahoogroups.com Date: Monday, May 10, 2010, 9:56 AM Hi Guys: Does anyone have any experience with the Marconi 2955B test set?

We will set it to 107.2 and the next time you check it is off enough to where it won't decode until it is re-tuned slightly. I am wondering what your experiences may have been with this CTCSS Chip. Many articles say they work well with the addition of a stable voltage regulator, so we added a five volt regulator, no difference in stability. Any comments and experiences with this and other chips would be appreciated. The availability of CTCSS Chips seems limited.

Or 300415916872 puts one in your hands for $70 including a battery. The MT is much more durable than most of the HTs out there, and no more hassle to program than any other Moto radio. You program the transmit frequency, transmit PL tone/DPL code, receive frequency, receive PL tone/DPL code all as separate fields on each of 16 channels. Maximum versatility. See http://www.repeater -builder. com/motorola/ genesis/genesis- index.html The only mod I do is that I add an AC power on/off switch to the chargers. The stock configuration has no AC power switch and the internal 24v DC supply runs 24/7. Disclaimer: I have no relation to the sellers, or to the particular radios. Mike WA6ILQ

You can have one or the other, required a board change to go from one to the other. Tone set by dip switch. Large battery = more power out. Short usually meant 1 watt, long 5 Watt. A P10 had only one channel 1 watt, P50 usually had 2 channels with Mic/headset Jack and 5 watts. Both came in short or long case. Two crystals and caps needed to change or add a frequency. I have LOTS of these P10's and P50's I would sell cheep with chargers, spare parts, service manual the works. I also have the tool to remove guts from the case without using two screwdrivers. There is also an antenna adapter to BNC. Real technicians used to work on these. You had to know how to solder! I liked them for what they were. Most are VHF. Some with PL, lots of spare DPL boards. Batteries included but unknown condition. New batteries are still available for cheep about $18. There were many different versions and often they got recased so no telling what you got till you pulled the works from the case. Great radios, good range, tough and simple. You can drop one many times and no damage. Good for people who don't have a clue on how to use a radio like at a community festival or mom to mom sale. I am located SE Michigan Shanon KA8SPW

Re: [Repeater-Builder] Motorola Radius P50
The short version is lower power than the tall one. 7.5v @ 600ma on short one, 10.8v pack on longer version. Dip switches are for pl tones only. Correct on units being crystal. Agree with you on ebay; I would'nt pay $5 bucks! 44 pretty sure is UHF @ 4 w, short 1w ? (do not quote me on this; threw those things out MANY moons ago.)

Re: [Repeater-Builder] HLN1185 Heatsink Material?
aluminum can be cast as well as drawn. the drawn type is usually thin, with respect to the cooling fins, where a cast type can be just about any size. aluminum is the most common metal for use as a heatsink as it has a very high temp coefficient, is easy to machine, and is cost effective from a manufacturing standpoint. magnesium would be expensive and depending on the grade would make a very nice signal flare. maybe there is some type of magnesium alloy out there, i personally have not heard of it. if you find out it is, let me know. --- On Sat, 12/26/09, Kris Kirby k...@catonic.us wrote: From: Kris Kirby k...@catonic.us Subject: [Repeater-Builder] HLN1185 Heatsink Material?

Those loops as you refer to are actually inductors of a very small value. They are in all intent a passive component. The size and shape derives the inductance value.

It appears to be a late model version because it has the Z-Match board right above the RF output connector. At 13.6 volts and 21 amps, it's doing 100 watts easily. I can vary it down all the way and vary it up to about 128 watts. So, to me it seems like it's in good shape. I left it key'd for 30 minutes and the current and power output stayed the same, 21 amps and 100 watts. After letting it cool, I key'd it up again. It immediately went up to only 20 watts, then after about 30 seconds it hit 75 watts and finally after close to a minute and a half, it hit 100 watts. I let it cool again, and same thing. This appears to be the way this amp is as nothing I can do can get it to change. I checked the exciter and immediately upon being key'd it puts out 220 mw. Any thoughts or suggestions would be greatly appreciated. Thanks!! Adam N2ACF

RE: [Repeater-Builder] Uniden Key
it was a standard blank for a padlock key, very common. don't know why he could not have one cut. the blank that was cut had no identity #'s on it. came right off the carousel at the mom pop hardware store. i sent pics of my original to Mike wa6ilq to post. --- On Wed, 11/18/09, Eric Lemmon wb6...@verizon.net wrote: From: Eric Lemmon wb6...@verizon.net Subject: RE: [Repeater-Builder] Uniden Key To: Repeater-Builder@yahoogroups.com Date: Wednesday, November 18, 2009, 12:31 PM Kevin, Please advise the brand name of the key blank, and the key blank identification number, of the duplicate key that that does work. This might be something like Curtis B173. Once we have that valuable information, it can be added to the RBTIP Radio Keys data file. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@ yahoogroups. com [mailto:Repeater-Builder@ yahoogroups. com] On Behalf Of kevin valentino Sent: Tuesday, November 17, 2009 5:46 PM To: Repeater-Builder@ yahoogroups. com Subject: Re: [Repeater-Builder] Uniden Key i just had a copy cut for a tech. tell your key cutter to look again, the one i fought with (a master locksmith) finally found a standard blank staring him in the face on the carousel. the confusion came when i told him it was to open a 2-way, the head was a different shape. --- On Tue, 11/17/09, Scott Zimmerman n3...@repeater- builder.com wrote: From: Scott Zimmerman n3...@repeater- builder.com Subject: [Repeater-Builder] Uniden Key To: Repeater-Builder@ yahoogroups. com Date: Tuesday, November 17, 2009, 7:13 PM Does anyone have any spare keys for the Uniden Force series of trunk mount mobiles? (1100 series) I managed to borrow one, but the key cutter I stopped at to get a copy made didn't have the correct blank. I was just wondering if someone had about 3 spares or so they would want to part with. Thanks, Scott Scott Zimmerman Amateur Radio Call N3XCC 474 Barnett Road Boswell, PA 15531
