[Repeater-Builder] Re: What have I got?
Sound like a PURC unit. You have exciter at 450 mw out that goes into a tripler/low level amp that gives 2W out, that goes into the 75 watt amp which in turn drives the last stage. Not bing familiar with the model number, I would guesstimate the final out is around 350 watts. Dan N8DJP

[Repeater-Builder] Astron RS50 Power Supply
Hi Guys, I am trying to download a schematic on this site for the RS50M Power Supply and keep getting a 404 Error on each attempt on all the supplies. Any ideas? Also our above mentioned power supply which operates our 2 Meter and 440 Repeaters and a low power link started humming yesterday. A trip to the tower showed that the two large wires coming from the Pass Transistors to the post on top of the regulator board and into the 1000 Uf Electrolytic got so hot it melted the insulation an inch back on the wires, burned an area the size of a quarter on the fiter side of the regulator board, turned the terminal black on the Cap. and cracked the plastic on the cap. It never blew the fuse and a check of the voltage showed it regulating under load and hardly a trace of AC on the 13 volt output. The MOV or eight amp AC fuse never blew. All the equipment hooked to the supply took off and worked well on another supply. Anyone have a guess as to what caused this obvious surge ontop of the cap? I am going to replace the Cap. and one resistor on the regular board which is discolored and hope for the best. Any advise appreciated. Thanks in advance JIM KA2AJH Wellsville, N.Y.

RE: [Repeater-Builder] Astron RS50 Power Supply
Leroy, The problem is that the jumper wire or PCB trace- if it exists- will create a common and low-impedance connection between the AC and the DC sources in a station. 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.

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.

[Repeater-Builder] REACT Urges Opposition to FCC NPRM 10-119
REACT Urges Opposition to FCC NPRM 10-119 Just released FCC NPRM proposing a complete rewrite of the entire Part 95 Rules: NPRM FCC-10-106A1 (10-119) The FCC NPRM requests comment and discussion of their proposed changes, which, among other things, propose to end the requirement for licensing in GMRS, LOWER the power allowed (to 2 watts for portables), potentially remove repeaters, firmly prohibit scrambling of any kind, and perhaps, prohibit use of radios dual/type accepted for part 90 and 95! PDF http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-10-106A1.pdf DOC http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-10-106A1.doc TXT http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-10-106A1.txt At a glance, the NPRM explores these main topics for the GMRS, FRS, and CB radio services: * Eliminate GMRS licensing (aka license by rule), similar to the FRS and CB spectrum, or extend licensing term from five to ten years. * Relax eligibility requirements. Under the current GMRS licensing regulations, only those aged 18 years or older are eligible to apply for a GMRS license. According to the FCC, if licensing is eliminated, it will be very similar to the FRS service, which has no such age restriction, so they don't find a reason to continue the age eligibility requirement. * Move to narrowband 12.5 kHz spacing. Currently GMRS uses 25 kHz spacing. Moving to narrowband FM would provide better spectrum management. * Decrease GMRS handheld radio output power from 5 to 2 watts. * Eliminate the use of repeaters in the GMRS service. * Consideration of a petition from Garmin to allow the transmission of GPS location information and user-generated text messages on certain GMRS channels. These emissions are already authorized on FRS channels, but Garmin would like the FCC to consider allowing it in the GMRS spectrum. An example of such a radio that is on the FRS service is the Garmin Rino 110 https://buy.garmin.com/shop/shop.do?pID=6404ra=true# . * Prohibition of approval of dual VHF Marine/FRS radios. * Clarification of regulations to explicitly allow hands-free microphones to operate in the CB band. * Decrease the allowable output power or prohibit the use of directional antennas for CB radios.

Can anyone tell me how many amps this power supply is: Model Number 1093 It had powered a UHF repeater that was in a cabinet, I do think at one time there may have been a AMP in the rack, but do not know that for a fact.

[Repeater-Builder] Astron RS50 Power Supply
Thanks to all who replyed to my question on the Astron. Mike, I did not check the box on the 404 Error, but Chuck sent me a copy of the schematic and when I returned to the site they all opened. Thanks for the heads up on the Astron Page, I am re-reading as I don't think I have the Cap. you mentioned.I also have to check to see if Negative Stud is insulated from the case. I replaced the 1000 Uf Electrolytic and it took off. Any of the suggestions, i.e. Loose Screw on the filter Cap. or a Bad filter Cap after 20 years could have been the problem. Again thank you all for the information. Now to fine tune it before I cover it up again. 73 JIM KA2AJH Wellsville, NY

Re: [Repeater-Builder] Re: What have I got?
Thanks for the Replies so far- I have found a little info on the unit. It appears to be a 225-250W 450-470 PURC amp. It is supposedly 20-25W in, but I have not found what PA would be the correct IPA. In the cabinet I found that the amp was bypassed, the unit was using the 75W pa as the final. I found the motorola manual numbers for this unit, so now begins the search for one. Hopefully the Tube in this puppy is still ok. If anyone has any more info on this unit PLEASE feel free to pass it along. Thanks! Tom W9SRV
[Repeater-Builder] Re: What have I got?
Tom, We have several of these 225 watt units in operation 440 MHz. The correct PA is the 20 watt unit. It looks identical to the 75 watt chassis, just has fewer circuit boards on the inside. Yes it is overkill for this much heatsink for 20 watts output power, but one needs to remember that these radios were not only designed to, but were very capable of running key down 24/7. Before I got all excited about having the wrong PA being used as a driver, I would pull the cover off of the solid state PA unit and see what it has for parts on the inside. You may have a 75 watt unit that has been modified by either removing or bypassing the high power driver and PA boards. The 20 watt chassis will have two circuit boards on the right side of the PA chassis (the end with the input cable) and the left side of the chassis (the end with the output cable) should be empty of circuit boards and transistors. I do not have my manual handy, but most of the Micor UHF station manuals should have the part number for the 20 watt PA chassis. If the unit actually has a 75 watt PA that has been used to drive the tube, about the only damage I would expect would be to the grid circuit. The use of 75 watts of drive may have shortened the life of the tube due to over driving the input. These PA decks will move to 440 MHz with some work and retuning of the tube cavity plates on each side of the PA deck. What you are looking when tuning the PA cavity is max power out at minimum plate current. If you are not familiar with High Power transmitters, please be careful of the 1500 volt plate supply. It will knock you on your A** or worse. Make sure all of the interlocks work and you have a good way to bleed the high voltage off before getting to carried away working on the PA deck or power supply.
