Re: [Repeater-Builder] Re: Sinple COS Circuit

[Steven Passmore]

If your talking about the TM-V7A/E The packet connector has a COS line, but 
for the record it is carrier only, PL has no effect.

If you need PL, it's hard to get since the CTCSS decoder is shared between 
the bands. The RX mute transistor can be tapped for CSQ+PL per band.

The service manual for this radio is readily available on the net

Re: [Repeater-Builder] MTR2000

[Eric Lemmon]

Brian,

The 100 watt MTR2000 comes in two ranges, 132-154 MHz and 150-174 MHz. 
You have to specify which range you want when you place your order,
because you cannot program them out of band.  The MTR2000 handles all
intercommunication between modules in digital format, and the embedded
code in the PA module tells the exciter module what range it will
handle.  Since you can't buy a Depot manual for the VHF station, you
have no schematics to guide you even if you could open up the sealed
modules.  High-tier radios like the MTR2000 are not intended to be
repaired by users or dealers.  Motorola expects you to have a stock of
FRUs (Field Replaceable Units) on hand to exchange, and you send the bad
unit back to the Elgin service center for repair.

The receiver, exciter, station control module, and the 30 or 40 watt
stations will program over the full 132-174 MHz band.  If you find
someone with a 100 watt VHF MTR2000 station selling for a very
attractive price, you should be careful to determine that the PA is in
the range you want.  Otherwise, you will plunking down some $1200 or so
for a PA that is in the desired range.

Some MTR2000 stations have an external preselector that looks a lot like
the Micor resonator block, and the receivers in such stations are
specified for either the 132-154 MHz band or the 150-174 MHz band.

Hi Eric,

I agree with you that the MTR's are super machines... but I was
wondering about something.  I had been told a while back that the VHF
machines wouldn't do 2 meters... something about the VCO's or some such
wouldn't lock, or maybe it was the PA that wouldn't do it.  Would you
share what you did (or what options your station has) to get the
MTR2000 to do 2 meters?  I'd love to know, in case one ever comes my
way...

Re: [Repeater-Builder] Re: motorola R-100 repeater

[Brian Poellnitz]

Best thing to try :

Get the MoSlo program here... http://www.hpaa.com/moslo/
Use it at the default speed (IBM PC/AT 4Mhz).  This should allow the
R100.com program to run on most any system.  If it still won't run,
DISABLE CACHE in your CMOS setup and try again.

Also, if you're dealing with a 450 split R100, you will probably have
to hex edit the R100.com file to modify the allowable bandsplit. 
Directions to do so are here...  http://www.batlabs.com/r100.html

Good luck & hope this helps.

RE: [Repeater-Builder] DB224 VSWR Readings

[Paul Finch]

Hello,
 
Remember when Phelps 
Dodge/Celwave/RFS came out with a competing 4 pole exposed dipole?  I was 
working for a nationwide paging company and my boss had Motorola Batwings 
tattooed to the backside of his eyelids, of course that meant he only 
used Phelps Dodge antennas, I think the number was PD-341 TP (TP stood 
for Two Piece).  
 
Long story 
longer.  At every site where we installed them they showed a lot 
more reflected power on a Bird 43 wattmeter than the DB-224 or 
DB-301.  Usually from 5 to 7 watts reflected with 250 watts 
output.  This was way before the sitemaster.  
 
I always liked the DB antenna 
better and that certainly proved it to me.  I have had a DB-410 on a 
building top in Fort Worth for over 25 years and it was a used antenna when I 
got it!  By the way, I personally know two of the engineers that designed 
that antenna for DB, great guys.
 
By the way, my boss had to eat 
a lot of crow when all of the Technicians coast to coast reported the same 
thing, yes we went back to DB and had no further problems.  I still have a 
PD-340, well the mast at least.  I am making a lightning arrestor for my 
tall tower out of the single piece aluminum mast!

Re: [Repeater-Builder] MTR2000

[Eric Lemmon]

I have two MTR2000 repeaters in service now, one commercial UHF and one
Amateur 2m, and I can't say enough good things about them.  Both are 100
watt machines, and both are designed and built for continuous duty.  An
optional I/O board and accessory connector harness allows the unit to do
almost anything.  However, both of my units use the internal controller,
and I am satisfied with its performance.  (I am geared toward Public
Safety radio, and I don't use voice announcements, courtesy beeps, or
other bells and whistles.)  MTR2000 stations are not cheap, and you MUST
know what options to order or you will pay far too much, or the station
will not operate on the pair you intend.  Caveat Emptor!

RE: [Repeater-Builder] reposting - single antenna, two receivers

[Bryan . Dorbert]

That makes more sense Derek. I'm have repeaters setup this way. The bandpass
filter can probably be tuned for either receiver freq and it should work
fine on the other. You could also get a 1:2 splitter to accomplish feeding
each receiver. That way you wouldn't have to worry about the exact cable
length.

Subject: [Repeater-Builder] reposting - single antenna, two receivers




Hi,
I reread my original post, it should read the following:

I am looking to use a Sinclair Reslok Q3220E UHF duplexor  (insertion loss
of .5 dB and rejection of 65 dB) tuned to 444.975/449.975 mhz.  I have a UHF
Master 2 repeater (run 30 watts) and a spare UHF receiver.  I plan to have
one receiver tuned to 449.975, the second to 449.950.  I also have a high Q
bandpass filter.  If  I was to run after the duplexor the bandpass filter
tuned to 449.9625, (then a low gain preamp) then a tee then 1/4 wave of
feedline (take in account velocity factor) to each receiver would this work?
Is there a better way to do this?

The site is at a commercial broadcast site, antenna is at 300 feet (2 bay
folded dipole) and is replacing an exec 2 repeater at the same site, which
works quite well.

Any ideas or suggestions?

Derek - VE5SD

Re: [Repeater-Builder] UHF Mitrek LO leakage mitigation

[Eric Lemmon]

Steve,

The single most important step in mitigating fugitive LO emissions is
ensuring that all shields are in place and properly seated, and all
screws are in place and tight.  Anyone who has had LO leakage with
Micors knows that you can't leave out any shields, and the same
precaution applies to Mitreks and almost any other brand or model.

If the shields are in place and the covers are tightly fitted, then
adding ferrite filter cores on the power and control leads may help. 
The fact that your Mitrek has been modified suggests that the mods may
be at the heart of the problem.  I'd look first at any DC control leads
that enter or are near the LO, and apply ferrite chokes or feedthrough
capacitor filters as appropriate.

Re: [Repeater-Builder] UHF Mitrek LO leakage mitigation

[Gran Clark]

Hi Steve
Two things come to mind with using silver solder.  1.  It is
stronger.  2. Most importantly, if you are soldering silver plated
parts the plating will become dissolved in the normal lead tin
solder.  A 3% silver lead tin solder will prevent this
migration.

list of things to check when I get there. I know the preselector can be
problematic, as well as the channel elements themselves.
What have the lest members tried with success to mitigate the LO
radiation from Mitrek mobiles?
I know that this radio should have have the preselector cold-end helical

with silver solder.
Does anyone know why silver solder is preferred?

[Repeater-Builder] Re: Sinple COS Circuit

[Coy Hilton]

I dom't think that I have seen a TM-7V. I looked on the Kenwood site 
and didn't find it. If you mean the TM-V7A, what you need is already 
brought out on the front of the radio it's on the "packet" 
connector. I forget what it's called but it is something like "busy" 
or something. If you have a schematic of the radio that you're 
working with you can tap the Squelch switch if it is brought out. 
Most radios these days have a receive busy indicator most are LEDs 
you can tap that with a transistor buffer circuit.
good luck

[Repeater-Builder] reposting - single antenna, two receivers

[ve5sd]

Hi,
I reread my original post, it should read the following:

I am looking to use a Sinclair Reslok Q3220E UHF duplexor  (insertion loss
of .5 dB and rejection of 65 dB) tuned to 444.975/449.975 mhz.  I have a UHF
Master 2 repeater (run 30 watts) and a spare UHF receiver.  I plan to have
one receiver tuned to 449.975, the second to 449.950.  I also have a high Q
bandpass filter.  If  I was to run after the duplexor the bandpass filter
tuned to 449.9625, (then a low gain preamp) then a tee then 1/4 wave of
feedline (take in account velocity factor) to each receiver would this work?
Is there a better way to do this?

The site is at a commercial broadcast site, antenna is at 300 feet (2 bay
folded dipole) and is replacing an exec 2 repeater at the same site, which
works quite well.

Any ideas or suggestions?

Derek - VE5SD

That's happened to me several times.   I now compose my emails
in notepad and cut and paste into yahoo.  If it croaks I have a copy
on my desktop and I can do it again.  Once it goes through I nuke
the desktop copy.

I just installed one of the duplexers on my repeater for 2 meters and 440,
no problems as of yet, coverage is the same.  This is one with the pigtails.

I guess that could be a problem, but I've had pretty good luck with 
mine.  If they are kept in a controlled environment so the coax doesn't 
pull in water, they should be OK.  If you're really concerned about it, you 
can go with a pigtailless model.

[Repeater-Builder] Ref: 2M/440 crossband couplers

[Repeaterman]

Arguh!

I had a long reply typed up with our experiences and how not to use 
the Comet/Diamond, etc... diplexers for repeater/commercial 
installs, and YAHOO ate it!

In short, use commercial crossband couplers, like the TX/RX 
crossband couplers.  Last I looked they weren't on the TX/RX 
webside, but here are their numbers:  Weatherproof Tower Mount unit: 
80-05-07, Base Station Mount: 80-05-06.  They are expensive, so 
beware.

I also saw recently that DCI makes, what appears to be a nice unit, 
for almost half of the TX/RX unit, but with a higher dB loss:

http://www.dci.ca/photos_diplexerdualband.htm

In our next dual band repeater install, I may experiment, and put a 
TX/RX weatherproof unit on top, and a dci unit below.

The ARRL also had a nice article under 'Product Review' in the 
December 2004 QST, which if you're an ARRL member you can read 
online:

http://www.arrl.org/members-only/prodrev/pdf/pr0412.pdf

Hope this helps.

Re: [Repeater-Builder] DB224 VSWR Readings

[TOM MANNING]

Mathew
Our club ran a DB224 for about 5 or 6 years until Ivan came along.  
We started with a gift DB224 which was inoperative due to a shorted 
harness.  We modified the elements to 37" long by adding aluminum pieces 
which we heli-arced.  Then we ordered a new harness for the two meter 
band and when received we repositioned the elements and dressed up the 
cables.  We then checked the VSWR and found to be about 1.1:1 at our 
operating frequency.  The Antenna was then installed atop a 150 Foot 
water tank.  This antenna gave very good service until Ivan came 
calling.  Ivan bent the antenna at a 90 degree angle and the VSWR went 
up to 2.2:1.  Our previous repeater antennas lasted from 2 months to 6 
months and were destroyed by lightning.  I talked to a Cushcraft 
Engineer about our problem and he suggested we remove the antenna every 
time a lightning storm came and put it under someones bed to prevent 
damage.  Our cost for the DB2234 we modified was less than $175.

I've found these at swap meets as cheap as $10.  Probably less than the 
parts you'd need to build your own.

Re: [Repeater-Builder] Programming PL on a CAT-1000 controller

[Sean]

Hi Mike,

The CAT controllers do not have a built-in PL Decoder and/or Encoder.

The PL setting in the controller is only used for access requirements 
(ie.. is PL required to key up the repeater).

In order to change the RX or TX PL Frequency your going to have to 
reference the documentation for your PL Decoder/Encoder.

Let the group know what PL board your using and maybe we can point you in 
the right direction.

73,
Sean

[Repeater-Builder] Programming PL on a CAT-1000 controller

[Mike - WM4B]

Greetings all, 

I've recently joined up with our club repeater guru and I'm trying to 
get smart. 

We need to set a temporary PL for some troubleshooting efforts (we 
have a mixing problem which causes the repeater to kerchunk itself 
continously when the transmitter output mixes with some other (as yet 
unknown) signals. Can somebody step me through this? The book only 
mentions PL back in the remote-base section, which confuzes me a bit. 

At any rate, we want to set the PL to 82.5 Hz, and it MUST NOT be 
retransmitted (or our troubleshooting efforts will be moot). 

To make things more interesting, the last time our repeater guru went 
to the site, he could not send or receive data between the controller 
and his laptop. (He was able to log in, but could not send/receive 
data.) 

Any thoughts? The last repeater I worked oin was only slightly more 
complicated then two native-americans sending smoke signals back and 
forth. 

Thanks, 

Mike

[Repeater-Builder] UHF Mitrek LO leakage mitigation

Hi,

I have a modified UHF mitrek mobile in repeater service which is emitting a 
strong signal at 1/3 of the LO mixer injection frequency.  Before I travel to

check when I get there. I know the preselector can be problematic, as well as 
the channel elements themselves.

What have the lest members tried with success to mitigate the LO radiation from 
Mitrek mobiles?

I know that this radio should have have the preselector cold-end helical coils 
resoldered. A Cactus technical article mentions this should be done with silver 
solder.
Does anyone know why silver solder is preferred?

Re: [Repeater-Builder] Is delivered mail

[mch]

It IS? My AVG caught it, as did my Norton (they both usually do).

Now, if you notice, look at the sender's 'certification' (which you can
turn off in AVG - both the incoming and outgoing certifications). It
says "Internal Virus Database is out-of-date."

You can hardly blame a program that is telling you it needs updated to
work properly. That said, I don't know what an error message should look
like, but AVG normally says that the "incoming" or "outgoing" email
(depending on the case) was scanned - NOT just "Checked by AVG
Anti-Virus." I suspect that footer, too, was fake. 

As for any other comments, the addy was likely spoofed and didn't even
come from Ted.

  Well, I don't have the schematic diagram of the Kenwood TM-7V

  Using the schematic diagram, I can usually locate a squench tap-off

RE: [Repeater-Builder] Transmit Problems Solved

I agree Mark.  Sounds very weird, but there is no other explanation as to
what happened.  If it was a problem with the Antenna, it would still be
present, or would have happened when it snowed and got windy the other day.
SO far everything is back to normal.

[Repeater-Builder] Homebrew a 2M/440 crossband coupler?

[derek_mcintyre]

Hello Group,
Does anyone have, or know where I can get plans to homebrew a 144/440 
MHz crossband coupler (aka "diplexer") ??  I would like to find 
something with wideband characteristics (ie, low pass, high pass) 
such as some of the diamond or comet models, but needs to be able to 
handle 100 watts FM continuously from each band, without excessive 
loss and without duplex noise, or little capacitors smoking.  Any 
suggestions, other than the Telewave models that cost over $300?

Thanks,
KC4FWC

I have an MTR2000 and use it for GMRS,  I am a Police Officer and 
found that my Dept uses, the MTR2000.  It is very reliable and a work 
horse. Easy to program and easy to attach a Zetron controller  with an 
ordered cable, plugs right in  (but it does cost alot  250.00) So 
total the community repeater pannel cost around 500.00,  but it is a 
terrific unit. I have the 100 watt unit turned down to 25 watts and it is 
perfect for my needs. I would say if you have the money  get the repeater 
it is worth it in the long run.

Your computer may be way too fast, the R100 s/w is OLD, and does not 
run correctly on any faster than a old 286 10mhz with DOS 5xx or 6.0.

You could also have a bad EEProm, or bad data in it, common problems.
