Re: [Repeater-Builder] Micor PA question
Kevin, As others have said, the model# is key to knowing what to expect. My personal experience is that if you are in the 146 or 147 MHz range you may be OK, but if you are in the 145MHz range, you will probably need to convert your amp to the low range. My TLD-1693 amp would only make about 20 watts and had higher than normal current draw when attempting to run it at 145.230. The TLD-1692 amps are out there, but are somewhat hard to find. Good luck and 73, Kevin, K9HX At 10:38 AM 1/20/2005, you wrote: I have a 110 watt PA from a micor base, that was on the low end of the 150mhz range.

I think I have the schematics for this someplace but have to dig them up if needed. TIA to all. Kevin K2KMB Yahoo!

Re: [Repeater-Builder] Micor PA question
Kevin, A proper answer to your question requires advance knowledge of the specific amplifier you have. Since you stated that your PA is rated at 110 watts, I must assume that it is an intermittent duty PA. Intermittent duty PAs were offered in three band splits: 132-150.8 MHz (TLD1682), 150.8-162 MHz (TLD1683), and 162-174 MHz (TLD1684). All of them expect a 400 mW drive signal. The continuous-duty PAs- which differed mostly in the size of the heat sink- were also offered in three splits: TLD1692, TLD1693, and TLD1694, respectively. The ideal PA for the 2m band is either a TLD1682 or a TLD1692. The reason that Motorola decided to make three band splits for the Micor VHF PAs is because Motorola found that the stability of operation and the purity of signal worthy of their top-of-the-line equipment called for PAs that were optimized for their respective band splits. Take a close look and the parts lists for each amplifier, and you'll see that there are between 70 and 90 differences in component values between them. I know that a few dedicated Hams out there have painstakingly converted a TLD1693 PA into a TLD1692 version, but it was expensive and labor-intensive. However, those modified PAs worked perfectly and met all performance specifications. Despite what some folks may say, you can't do a few simple mods to a Micor PA and magically transform it into a different band split. There are good reasons for every component, and there are no shortcuts. 73, Eric Lemmon WB6FLY Kevin Bednar wrote: I have a 110 watt PA from a Micor base, that was on the low end of the 150 MHz range.

[Repeater-Builder] All the same radio! Try?
Hello All, If you are on a quest for a Midland 13-509 there where a pile of radio's that where the same radio. Midland made 3 ver. of the 13-509 over the years they all worked well. Also look for a Clegg FM-76 it was a Privite labeled Midland 13-509 also Cobra got into the picture with a Cobra-200 also a Midland 13-509 this one is real rare. In this area you can still fine Clegg FM-76's also if you need parts for any of the above Maggiore out in West Chester PA has boxes full of part. I bought a relay for a Midland 13-509 we have out in the den to monitor the repeater and the relay went south and they had one. That is a neat Midland. It has a out BD channel-lizer and an out BD Com-Spec. PL incoder. But it is on 24 hours a day and just keeps running. Good luck with you 220! Very best of 73, Russ, W3CH Yahoo!

Re: [Repeater-Builder] Mating a CAT-1000 and a Kenwood TKR-850E Model II
Hey Dave and the group, I installed a controller on my new Kenwood VER. two TKR-850 and had no problems. I used a Link-Comm RCL-3 I bought the jumper cable for it and it worked right out of the box. You have to watch the Cat controller as the PTT line to the Kenwood TKR-850 ver. two is back wards. Dean over at Cook told me that before I hooked up the controller and I ADJed the dip switched on the Link-Comm before I hooked it up. I am very happy with the sound of the Kenwood audio and the controller. If you check the out put of the Cat controller you can find out where the problem is. Controller or Repeater. Try this easy test. on the DB-25 jack on the back of the repeater ground the PTT pin if the Kenwood TKR-850 ver. 2 goes in transmit you have the repeater programmed right. Now lets look at the controller. With a VOM or DVM if you please go between the PTT of the controller and ground. If you show a short when you power up the controller it is in the controller. At this point look at the book for the controller and see how to change the PTT state. It should be active low to key the Kenwood. I have heard folks here of late have problems with the Cats being low on the PTT all the time and never go high. But the above test well let you know if it is in the Kenwood or controller. Then the fix I would think will be easy from there. Let us know how you make out. If it is in the Kenwood give Dean Westbrook a call over at Cook he is real sharp I am sure he will help you. He helped me allot on my 1st Kenwood. Very best of 73, Russ, W3CH. - Original Message - From: David A.

Re: [Repeater-Builder] Micor PA question
I found several of the 2-Meter range TLD-1692 MICOR 100-watt PAs on ebay, rec.radio.swap, etc. over the last couple years. I bought three them for myself as spares since I have two - 2-Meter repeaters that use them. I converted four or five of the high-split range TLD-1693s into TLD-1692s over the years, by changing all of the M or H range parts shown in the service manual to those values for the L (low) range. Whenever I'd be on a business trip near Motorola in Schaumburg, IL, I'd make arrangements to FAX them a parts list of things I needed, then just stop by to pick them up. I still have one more set of parts to do one more 2-Meter conversion, but now that I have some factory spare PAs in the correct frequency split, I probably won't bother. It involves nearly stripping the original PA circuit board to change out many of the caps, coils, resistors, transformers, both trimmer caps, etc. and replacing them with the correct 2-Meter L range parts. Back about 12-14 years ago when I bought this last set of MICOR PA replacement parts, they probably cost around $150-175 total, with the most expensive parts being some of the special transformers and the two trimmer caps. I don't think that many of the parts are available any longer from Motorola, but some of the parts (like the transformers) have an equivalent replacement as MSR-2000 VHF PA part numbers. You just need both manuals (MICOR and MSR-2000) to compare schematics, circuit board layouts, and part numbers side by side before you contact Motorola to check on parts availability.

Boy It's been many years sence I'v worked on one. ---Many years ago, I converted a Pulsar II mobile into a repeater. They were kinda neat in this regard as they were like Micors, in the sense they only needed one xtal and had a 5 Mhz IF. So offsetting was easy. At the time, SoCal used reverse splits on UHF (don't know if they are still low in/high out down there) so it was a piece of cake to do. The only real problem I found with the Pulsar was that it used PNP PA devices (and perhaps even germanium ones too?), and was a PITA to repair. It was also basically a VHF radio with a varactor tripler and no active stages afterwards. Working from my photographic memory, which seems to be running low on film these days!

[Repeater-Builder] Circulator vs. Isolator
List members, Is there any reason that a circulator could not be used as an isolator? Assuming appropriate power handling capabilities, I would think the former would work just fine. Amp output into port 1, Bp/antenna on port 2, dummy load on port 3, and any reflected power from the Bp/antenna should be absorbed by the dummy load. Am I missing anything here?

Scott Madison, WN1B Nope-that's basically the way they normally get used. I assume when you say Bp/antenna that you mean a band-pass cavity in line. Normally a low-pass filter is used, not a cavity, because cavities can frequently be resonant on the second harmonic (or higher), which is what you're trying to filter out. Circulators normally generate harmonics. -- Jim Barbour WD8CHL Yahoo!

[Repeater-Builder] Powering the Repeater With Marine Batteries
Last night my power supply took a dump! Good thing for backups. Anyways, what I am wanting to do is put 3 marine batteries together to run the power for the repeater with a charger to charge the batteries. If I use a 12 Volt Car charger, do I risk the chance of noise, or would the batteries filter that. What would be a good source to charge these batteries? The power supply that will be taking the place of the worthless Pyramid supply will be an Astron 52 Amp Rack Mount Supply. I have heard in the past that batteries have been charged with these power supplies, but not sure if this if true or not. Any ideas? Thanks. Mathew Yahoo!

[Repeater-Builder] Re: Powering the Repeater With Marine Batteries
Look on the Kevin's Web site under Astron power supplies for info on how to use an Astron to float batteries. There needs to be a diode between the power supply and the batteries to prevent the batteries from discharging back into the power supply when the AC is gone. You can alos use a BIG relay that drops the PSU when the AC goes off. I actually do that with my Astron. When the AC picks up I force the repeater into low power (if it keys up) for a timed period to let the batteries charge up to near float voltage. The PSU needs current limit or it will blow out when the power comes on. So check repeater- builder for the astron modification dope. Or you can gin up something crude with relays like I did. 73 Ed K3SWJ --- In Repeater-Builder@yahoogroups.com, w9mwq [EMAIL PROTECTED] wrote: Last night my power supply took a dump!

[Repeater-Builder] Powering the repeater with batterys
Hello Mathew,I have used batterys to power my repeater for several years,with the type battery charger that is automatic.(15 to 20 amp)When the battery charge is full the charger shuts itself off,when it drops to a lower voltage it restarts automatically. This keeps the battery charged and don't boil the water out of it, like one that charges all the time.I have never had battery charger noise.Also as soon as the repeater keys it causes the dc voltage to drop and the charger kicks and carries part of the current load. Hope this helps Don / N5SVK 73 Yahoo!

Re: [Repeater-Builder] Powering the Repeater With Marine Batteries
One of the best ways to manage the charging of your batteries is to use a multi-mode charger designed to properly charge and maintain them. Ibex http://www.ibexmfg.com carries two 3 mode chargers that are very well suited for the job. If you look at their web page under the 12 volt chargers, the last one listed also has load shedding capability. That means that not only does it charge the batteries, but you can power the receiver, controller and exciter (but not the PA) through the load shedding switch and when the battery voltage drops, it will shut everything down; saving your batteries from total depletion. Using a charger like this you will still need to isolate the output of the AC power supply and the batteries. I personally prefer to do this with hard relay contacts so that you don't have voltage drop through a diode to contend with. Which ever way you choose, spend a little extra to charge the batteries correctly and they will last a very long time and be there when you need them. 73, Tony W4ZT w9mwq wrote: Last night my power supply took a dump!

Re: [Repeater-Builder] Powering the Repeater With Marine Batteries
The method I have prefered over the years is the Motorola Micor repeater TPN1105A/TPN1106A Power Supples that also charge the battery. The radio site near here uses that power supply to run both repeaters and charge the battery as well. Just my opinion. I have the one power supply that is in service and three more for spare parts. A number of years ago, had one site with three 100 watt Micor repeaters ... each repeater had one of the power supplies. The output of the three power supplies were paralleled and charged two Size 8D 'cat batteries.' One day I went to the site on a maintenance schedule and found one side of the radio systems primary power circuit breaker had failed. That caused one of the above power supplies to power all three 100 watt repeaters - for how long? I didn't know. Seems two of the repeaters were plugged into the failed side of the power line / the remaining repeater was on the other side of the power line. BTW, two of the repeaters were public safety / the power supply that was supplying all the power was on the amateur radio repeater.

RE: [Repeater-Builder] Powering the Repeater With Marine Batteries
Got one to spare...Hi HiI don't have a problem running the batteries, it's keeping them charged at a rate that they can handle. We don't often loose power here, but there are those times. I plan to buy a generator, but still like the idea of the batteries. I've had other's say they have just used a regular car battery charger with no problems. I'm just thinking there is no regulation or isolation at all on them. What is the thought on just using a battery charger.
