[Repeater-Builder] Micor receiver -- TLD0273B3PR

[bbedoe]

Hi all, 
 
I have an offer for a couple of Micor's that are SPLIT Band, TX is VHF-Low  
and RX is VHF-Hi Band.  The guy tells me the receiver is a TLD0273 B3 PR on  
151.XX.
 
I know enough to be dangerous about Micors and I was hoping that the RX  
would be ham split "2" receiver, but at the same time never heard of a '  
0273.  Special receiver due to the low band TX?
 
Any ideas?

Brian,

I suspect that the seller mis-read the number stamped on the receiver board,
and that it really is TLD8273-which is intended to operate 150.8-162 MHz.
The TLD8273 unit would be expected for the frequency you mentioned.

The number was hand-stamped, and it often happens that some digits are not
completely inked.

Regarding the conversion of the subject station to the 2m Ham band, you will
find a wealth of information on the Repeater-Builder Technical Information
Pages.  Start here:

How about the band pass, doubler/trippler and other stuff.  Is there
any need or mods needed?  I found
http://www.repeater-builder.com/micor/micor-uhf-conv/micor-uhf-conv.html
to mod the 450 to 470mhz "down" to the "L" range (406 to 420) but not
up.  Still learning the moto stuff...so forgive my questions. 
Hopefully this will help others in the same shoes later.

[Repeater-Builder] Mitrek/Micor Station test.

[w7hsg]

Hi all
Looking to procure the 12 pin male connector used for the meter socket for  
Mitreks

My test box (Moto R1033A) uses an assembly labeled RTK 4042APR which consists 
of a 37pin connector, cable and 12 pin male connector.  No part # is listed for 
the 12 Pin Male.   All I need is the 12 Pin mitrek connector but beggars etc.

Also could use the  5 Pin male connector used for Micors.

I need to make a test box for my son N7XVF in Montana.

You're trying to move a 406-420 range station up  into the 440-MHz range - quite a jump and often a challenge to move without serious modifications. You really want to find a 450-470 MHz range unit, to move down to the 440-450 range - it should tune right up. 
 
Save the 406-420 MHz station for a 420-430 MHz linking transceiver, or trade it to someone for a 450-470 range unit,  since they are nearly always available. The 406-420 ones are hard to find when you need one for a link...

Hi Folks,Have a problem with a Micor Station tonight. Have a Micor that was on409.600T / 407.275R . It was working great on those freq.s beforepulling the elements and sending them off to ICS. New elements (oldones were stolen in route!) with 444.600T / 449.600R in and ready togo. Receiver tuned fine. (slugs out awful far) Transmitter is alittle harder. I have gotten all the way down to the exciter output.(step 11 and 12) No go. Not sure if it is just too far down or what.The board is TLD5491A3. Is there any changes or mods need to be doneto make it happen on 444.600mhz?Thanks,Robertps Will be using a RC210 on this...any suggestions there would beappreciated :-)

[Repeater-Builder] Samlex Power Supplies

[Bob M.]

Is anyone running a Samlex 12V supply in a situation
where they can measure the voltage regulation from
minimal load to something near half load?

A friend has one of their 100A supplies (five 20A
units in one box) and he's seeing about 1V drop with a
35A load (2M power amp), which is a bit more than I'd
feel comfortable with. I don't know how they connect
the supplies in parallel, so this could just be normal
drop through the combining network, if any.

I can't find any specs regarding this on the Samlex
web site or in their manual for the SEC-1223. I would
hope the supply can hold the voltage to well within
1%.

For comparison, Astron RS35 supplies don't drop at
all, or if they do, it's under 0.1V, just losses in
the wiring.

Thanks.

After a catastrophic failure of a Samlex SEC-1223, I won't use them ever
again.

I had one that was powering a stack of 7 SpectraTAC receivers, an LDG voter,
and a 5 watt transmitter at a link relay site; total draw about 5 amps.  It
had been working fine for a year or more.  One day I unplugged the cabinet
to move it (we were re-organizing the room).  Later when I plugged it back
in, I heard a strange sound, and when I got around to the front of the
cabinet, I saw smoke coming out the voter and power supply.

Long story short, four SpectraTAC (Micor) receivers, the voter, and the link
transmitter were pronounced DOA back at the shop.  I momentarily powered the
supply up with a voltmeter connected to the output and found it was putting
out over 40 volts.

That was the last Samlex I used...

YMMV.

You mean 7 pin?

The easiest place to find those is in a SpectraTAC receiver chassis - there
is a little jumper with one of those connectors on each end that connects
the receiver to the interconnect board for use with the metering module.  If
you don't have the metering module, this jumper is superflous.

RE: [Repeater-Builder] Mitrek/Micor Station test.

[Eric Lemmon]

Ralph,

You're in luck!  Motorola Parts still has that unique 12-pin male plug in
stock, for about $17.  Not only was that plug used for MSY and Mitrek test
cables, but it also is used for a whole slew of program/test cables for
handhelds, such as the SP-50, HT1000, Saber, and others.  Since some of
those cables are still available for purchase, so is the connector.

Ask for Motorola Part 0180754A26.  I doubt that these plugs will be
available much longer.

Ouch!  Was this the one that caught on fire as well, or was that a 
different Samlex?  I wonder if an outboard OVP circuit would be in order, 
since the supply itself apparently has none.

I like the idea of using them at home for the efficiency so I can cut down 
on the electric bill, but not for mountaintop use because of the 
reliability & noise issues.  As long as I'm not billed for the electricity 
my systems use, I'll stick with linears.

RE: [Repeater-Builder] Samlex Power Supplies

[Eric Lemmon]

Bob,

I would expect a 20 ampere DC supply to regulate within 0.5 VDC, no-load to
full-load.  Since the power supply in question comprises five 20-ampere
units in parallel, that should hold true.

As it happens, I have been running load tests under controlled conditions,
on an assortment of brand-name linear and switching supplies.  My goal is to
see not only how each supply regulates and meets specs, but also to see how
efficient each one is.  Some linear and ferroresonant supplies are
remarkably inefficient.

I would hope that your 100 ampere supply is connected to a 240 VAC circuit,
or to 208 VAC if you have three-phase power.  A modern 20A power supply at
full load will draw about five amps from a 120 VAC power line, so we should
expect your 100A supply to be sucking up perhaps 25 amperes at 120 VAC.
That requires a branch circuit rated at a minimum of 30 amperes, with all
primary wiring #10 AWG or larger.  It is not a good idea to run such a load
at 120 VAC, if it can be wired for 240 VAC or 208 VAC. 

It may be that the AC input voltage is dropping as the power supply load
increases, and the individual units cannot provide full output.  Try
measuring the AC input voltage at the power supply during no-load and loaded
periods, using a known-accurate True-RMS digital meter.  You might be
surprised at how low the voltage can get.

You should check to see that the AC input voltage selection switch or
jumpers are appropriately set for the available voltage.  Appliances that
are intended for consumer use in the United States usually have only two
possible settings: 120 and 240 volts.  That's because nearly all
single-family dwellings in the US are fed from a center-tapped 240 VAC
transformer.  Ah, but here's the problem:  Apartment houses and condos and
hilltop radio sites are usually fed 208Y/120 VAC from a three-phase system.
There is no 240 VAC; the maximum line-to-line voltage is 208 VAC.  If you
plan to install an electric stove, water heater, clothes dryer, welder, air
compressor, etc., you'd better go to the "special-order" section and get the
appliance that is designed and rated for 208 VAC operation.  But, I
digress...

If your power supply expects to see 240 VAC but is only being fed 208 VAC,
it will not operate within specifications.

I have had excellent results with Samlex switching supplies.  Yaesu sells
the Samlex 1023 power supply with a Yaesu label.

[Bob M.]

Thanks for all the replies. Too bad I never got my
original message sent on the group e-mail ! Yahoo does
it again.

I think the supply is something that was sold for a
limited time to offer some kind of redundancy. I don't
know if it's entirely capable of 100 amps, but it is
only being fed by a standard 120V 20A circuit.

I agree that the supply should do better than what's
being seen at the moment.

I was considering getting one of the new 1235 models
for use at a UHF repeater, but maybe I'll hold off on
that for a while.

Bob,

>From the description of "five 20 A units in one box" it sounds identical to 
the Samlex SEC-100BRM as shown on the Samlex web site here:

http://tinyurl.com/358l57

The manual for the SEC-100BRM can be found at the Samlex site here:

http://tinyurl.com/3a7aa9

Page 20 of the manual shows:

Two modules equpped:
No load = 14.00 VDC
Full load at 40 amps = 13.65 VDC

Five modules equpped:
No load = 14.00 VDC
Full load at 100 amps = 13.35VDC


All five modules feed a common bus.  The bus is then fed to the load 
terminals through a Schottky diode for battery isolation purposes.

In my personal tests with an SEC-100BRM equipped with two modules I saw 
no-load of 14.00 VDC.  With a 7.5 amp load the output dropped to 13.89 VDC. 
Not nearly as heavy a load as your friend was seeing.

My guess is the output dropping one full volt is suspicious.

And as fair warning, I have discovered errors in Samlex documentation before 
so I approach their specs with a wary eye.

  Subject: [Repeater-Builder] Samlex Power Supplies


  Is anyone running a Samlex 12V supply in a situation
  where they can measure the voltage regulation from
  minimal load to something near half load?

  A friend has one of their 100A supplies (five 20A
  units in one box) and he's seeing about 1V drop with a
  35A load (2M power amp), which is a bit more than I'd
  feel comfortable with. I don't know how they connect
  the supplies in parallel, so this could just be normal
  drop through the combining network, if any.

  I can't find any specs regarding this on the Samlex
  web site or in their manual for the SEC-1223. I would
  hope the supply can hold the voltage to well within
  1%.

  For comparison, Astron RS35 supplies don't drop at
  all, or if they do, it's under 0.1V, just losses in
  the wiring.

  Thanks.

  Bob M.

Re: [Repeater-Builder] Mitrek/Micor Station test.

[Mike Morris WA6ILQ]

There are some part numbers on the Test Set page at www.repeater-builder.com

But you will probably find it easier and cheaper to buy a Micor 
station test set

(the one made to mount inside a Micor station cabinet) and rewire it to do
Micors and Mitreks.

The male connector that is used on Motrac / Motran / Mocom / Mitrek
test cables is based on a mil-spec hermetically sealed relay base with
one pin cut off (i.e. the Motrac design team used an existing relay
socket as a metering cable socket and had the manufacturer fill in one
pin). I built my first cable by purchasing a surplus relay with the proper
base, then cutting off one pin, then using a pipe cutter on the top of the
can, gutting the case, soldering the conductors from a piece of the bulk
test set cable to the connector pins, and then filling the housing with a
50% / 50% mix of RTV and hot melt glue.  It lasted for years until I found
a "real" cable, and I passed my home-made one on to a friend, still working
fine.

For what it's worth, the real connector is a 01-80754A26 assembly of the
base, housing, and cable clamp, and will run you just under $20

Hi all
Looking to procure the 12 pin male connector used for the meter 
socket for  Mitreks


My test box (Moto R1033A) uses an assembly labeled RTK 4042APR which 
consists of a 37pin connector, cable and 12 pin male connector.  No 
part # is listed for the 12 Pin Male.   All I need is the 12 Pin 
mitrek connector but beggars etc.


Also could use the  5 Pin male connector used for Micors.

I need to make a test box for my son N7XVF in Montana.

You're trying to move a 406-420 range station up  into the 440-MHz 
range - quite a jump and often a challenge to move without serious 
modifications. You really want to find a 450-470 MHz range unit, to 
move down to the 440-450 range - it should tune right up.




Save the 406-420 MHz station for a 420-430 MHz linking transceiver, 
or trade it to someone for a 450-470 range unit,  since they are 
nearly always available. The 406-420 ones are hard to find when you 
need one for a link...

Subject: [Repeater-Builder] Micor Station Exciter
Hi Folks,
Have a problem with a Micor Station tonight. Have a Micor that was on
409.600T / 407.275R . It was working great on those freq.s before
pulling the elements and sending them off to ICS. New elements (old
ones were stolen in route!) with 444.600T / 449.600R in and ready to
go. Receiver tuned fine. (slugs out awful far) Transmitter is a
little harder. I have gotten all the way down to the exciter output.
(step 11 and 12) No go. Not sure if it is just too far down or what.
The board is TLD5491A3. Is there any changes or mods need to be done
to make it happen on 444.600mhz?
Thanks,
Robert
ps Will be using a RC210 on this...any suggestions there would be
appreciated :-)

There's one in San Diego, so fortunately far enough away from the LA basin 
to not be a problem here.  However, I once had 1600 kHz in Pomona 
(then-KWOW) mix a 220 repeater output to its input.  Took me a while to 
figure out that the interfering signal on the input had a "beat" to it  ;)

Hi Gary, 

Is the flange resistor mounted to a hybrid combiner square module 
or is the combiner on a pc board..? maybe even an interface or 
in-house made combiner on the amp or separate pc board?

That might only be there for use when the plates are issued to the vehicle

Up here in Alberta the registration paper printed on the computer and the 
year/month stickers also have bar codes on them for tracking 
purposes.  Also our registries are now privatized so you have your pick of 
dozens of places to go in the larger cities and even villages of four or 
five hundred people usually have a registries office.   That same office 
might also have a credit union teller and/or post office and/or insurance 
agent and/or travel agent.  With one or two people with all the hats.


To stay slightly on topic our ham plates are free except for the service 
charge. You still have to pay the $50 per year registration fee of 
course.  The vanity plates are $250.
