[Repeater-Builder] Power supply identification request.
Hi to all on the list. I have lurked for a while and always get a great deal from reading the various posts and infos that are posted. I now have a question for the group: I am wanting to get some information on a powersupply that I have, which is ex repeater use. It is a Motorola and is model number 25D84880NO2. It has a 13.8v dc secondary and a 14 v dc secondary. The 13.8v is for supplying the radios and the 14v for charging batteries, it seems. I would like to use this as a power source in my motorhome and use the 14v to charge two 225 amp/hour Gel batteries. There is a circuit board on this supply with three 4 amp fuses and one 10amp fuse, an eight posted plug and an equalise switch. Can anyone help me with a circuit, wiring information, and idea of what the eight pins are for? All and any information will be muchly appreciated. I have two 55 watt panels to add to the setup also and would appreciate any ideas as to an ideal setup and control configuration to get the best out of the setup. Thanks in advance. ( Ps: it will have a mobile UHF repeater connected up... just to keep this post on topic :-) 73 de Graham Shaw ZL3TV ( ex - ZL3TDA ) Christchurch New Zealand. Yahoo!

Re: [Repeater-Builder] Power supply identification request.
Look all over the chassis for another model number, probably on a yellow or orange sticker, something that starts with TPN. This almost sounds like a power supply for an MSF5000, but I'm sure there are other similar station supplies. Same number and size of fuses, and the equalize switch would indicate it is the battery-charging version. But I hesitate to say that's what it is for sure because I couldn't find any reference to that 25D number. Bob M. == --- zl3tda [EMAIL PROTECTED] wrote: Hi to all on the list.

[Repeater-Builder] A couple of Micor questions..
First, thanks to all who responded to my requests for info regarding interfacing the RC-210. The repeater is on the air and functioning reasonably well! I do have another question though... I have a cont.-duty PA (Micor cont duty on 40MHz split) for it, and the interconnect board I have does not have the header pins for interfacing it. So it goes without saying I also do not have the associated cabling. Does anyone have info regarding how to make the outboard PA play? My question is, what gets tied to where with regard to the interconnect board and the PA. I couldn't find what I was looking for in my manual, as it is for an intermittant-duty compa-station. Actually I can't find much info in my manual regarding this PA. I did notice that it will have to be moved into the correct band-split so there is still some work in my future...

RE: [Repeater-Builder] A couple of Micor questions..
Mike, If the low band PA's are the same wiring configuration as the VHF Hi, there is a pin on the end of the Amp which must be grounded when you transmit. Other than that, it is just 12+, Exciter in and RF out. As I remember as you look at the component side of the amp, the pin is on the left end. I don't remember any other exterior connections.

RE: [Repeater-Builder] A couple of Micor questions..
Thanks Jim, I thought that was the case, but wasn't sure. I had played with putting one of these amps on a 2m machine about 5yrs ago... but didn't recall just exactly how I made it play. There is a single pin below what looks to be metering attachments (4 each, in a parelellagram above it). The only other question would be the header pins on the transmitter interconnect board and how they figure into the mess...?? I have 2 other chassis, and they have the header pins... just didn't want to have to do major surgery to change the interconnect board.

RE: [Repeater-Builder] A couple of Micor questions..
Mike, How about getting the ground you need for the PA from your controller instead of the backplane? When the controller goes into PTT it gives you the timing you need, i.e. the tail, etc. If the controller goes to ground on the PTT, you could get your ground there. If it goes high, you could use a transistor to invert the positive to ground. You wouldn't have to go to the backplane. This is one approach that may be simple?

RE: [Repeater-Builder] A couple of Micor questions..
Yup, I was thinking the same thing... although I may use a small relay to accomplish this. Depending on how much current the RC-210 can sink to ground, gotta check on that.

Thanks to all those who responded. I think I will forgo the 805-D's and look for a small 'ready to go' repeater. Intended use is for my parked vehicle, on-site at flea markets, fair grounds, parks, etc. The reason I was looking at 805-ds was the ease of being able to change channels/pl's if needed to not interfer with existing systems that may be operating in the area.

Re: [Repeater-Builder] Re: Kenwood TKR 820
and we all know what hapens when we ASSUME... hehehe I think that was said best in a Stevan Segal movie. Under Seige Pt.2 The TKR-820 will just sit there like a dumb shit until the magic tone is played for it on the channel that the receiver is tuned to. Pull out the 8 pin EEProm that is on the controller board, I think it is 94C56 , this will force the receiver into carrier access. Then one of the pots on the controller board is squelch, tweak it untill the repeater starts transmitting. Bust out your radio shack frequency counter or a modified handheld and count it up to figure out what it is transmitting on. Then try to set your radio for a common split, with + and - 5, 3, 2.5 or 1.5 and see which one brings it up. BTW, the controller is not the board behind the front panel, it is the small almost 3X5 board that sits in a tray above the radio chassis. Although the channels are set by the front panel board for what ever reason. It is possible to brute force program the EEproms to what ever channel and tone you want without the KPT-50, check the archive for the threads from about 5 months ago. Yahoo!

[Repeater-Builder] Re: milcom amps
The Milcom Amplifiers I have are all linear polyfet designs. I have converted some of the 220 ACSB repeater pa's over to FM with an increase in power output. If you sent me a good internal view picture, I could probably tell you if it's a linear mode amplifier. Good luck trying to get Milcom Amplifier information from anyone. But the designs are straight forward so regular fet amplifier theory works. If you need more rf amplifier information, please feel free to join us over on the rfamplifiers yahoo group. http://groups.yahoo.com/group/rfamplifiers/ cheers, skipp Kris Kirby [EMAIL PROTECTED] wrote: On Mon, 13 Mar 2006, Steve Hutzley wrote: Does anyone have any information/schematics on Milcom International amplifiers.

[Repeater-Builder] photos of dead MASTR II PA
Everyone knows about the web page that talks about doing the modification to the MASTR II PA with a piece of braid between the final board and the low-pass filter board... http://www.repeater-builder.com/ge/mastrIIparepair.html - And the page that talks about not driving the UHF PA into non-50-ohm loads... http://www.repeater-builder.com/ge/mastrIIuhfpacomments.html - Here's the photos of a *VHF* PA that didn't get the board to board jumper mod and the results of driving it into a load that wasn't 50 Ohm that was probably reactive in some way also... http://www.natetech.com/images/Burnt_SquawMtn_VHF_PA_03112006/ (We haven't determined exactly what's wrong with the load yet, but it was a pass-cavity that was throwing back 4W reflected at 70W input... not good... removing the pass-can and going directly into the combiner yielded 80W -- WITHOUT changing the settings on the PA -- and zero reflected. Bad juju going on there. We by-passed the can for now, so we can go back up when the site is more accessible and do more measuring.) - The PA that smoked in the photos was set to about 80W output at the site in the fall, before it was snowed in, and it did a nice job of smoking the connection between the final board and the LPF. I now have that unmistakeable smell of charred electronics in my Jeep. It's better than one of those Pine Tree thingys for giving my Jeep that smell of home. LOL! Kevin, if someone wants to edit these into an article for future reference, please feel free to copy them, edit them for size, etc. They're all yours. They're not perfectly in focus, but they're better than nothing. I can try to shoot a few more with better light to make the digital camera happier, if desired. I can also get (hopefully better) photos of some of the other standard failure modes of the M2 PA (yeah, we've had bad luck this year) as I go through the repairs... got a UHF on the bench with a power divider resistor turned to charcoal here somewhere, too...

Re: [Repeater-Builder] Digest Number 3664
More than likely the cause of your problemwas the connection between the two boards developed a cold solder joint and began to ark. This happens all the timewith thisPA. It may not have had anything to do with your load. If you have 70W going in and 4W reflected, that's about a 1.65:1 VSWR, which is not that bad. Chris In a message dated 3/13/2006 5:54:44 P.M.

Well, not bad unless you consider that coming out of that pass can, measured output was just under 70W with virtually zero reflected from the cavity to the combiner, which has a ferrite dual-port isolator as its first stage... So the reflected power was ALL from that single VHF pass-cavity (or cable going to it), tuned/coupled for only 0.55 dB insertion loss, and basically just in-line to be a good neighbor to another VHF system that was experimenting with using a receive antenna not on the combiner system and in the direct horizontal line of fire of the combined TX antenna everyone else is using at the site. We were attempting to help lower our output's effect on their input about 1 MHz away by about 10dB. Anyway, an experiment... yeah, the PA could have munched itself all by itself, I know... but I'm suspicious of a single pass cavity causing that much reflected power. Definitely wasn't worth leaving it installed for the moment... will re-evaluate when it's easier to get to the site. Nate WY0X Yahoo!

Run two 1/4 wave multiples (3/4, 1 1/4, etc.) from each T to get 100 ohms each to a 3rd T, which then gives you 50 ohms for the feedpoint. The reason it's important to use 50 ohm coax is because you can use a silver-plated coax for the harness (I don't know of any 75 ohm coax that has a silver-plated braid; it probably exists but is not commonplace). RG-59 RG-11 do not have a silver-plated braid will eventually generate desense when used in duplex service. Bob NO6B Yahoo!
