[Repeater-Builder] Duplexers

[Mackey]

Our club was recently given a 220 repeater. We have two seperate antennas.  We 
do not have a duplexer. My question is do we have to have a duplexer? How can 
we keep the transmitter from desensitizing the receiver? The antennas are apart 
but can be moved farther.
Thanks

If they are the 162-174 MHz range, then it will be major work to make it
function properly in the 2 meter amateur band.

Kevin - you are correct that the 162-174 receiver LO chain is the same as the
2 meter range, but changing out helical resonators is a lot of work. 
Basically, you need a small torch to do it right.  Then, getting the CORRECT
replacements or modifying the originals is not simple.

You are really catching at my weak point!!  You (and others) have invited me
to share information for web site posting in the past & I have failed to
present the information.  Most recently this was asked for the procedure of
proper care & feeding of 450 MHz Mastr Pro transmitters.  Further back, I was
asked to post on how I built a link to my repeater in Iowa over the internet
starting in 1998, long before eQSO, IRLP, & other similar programs were
available.  I really should share more information, I just keep putting it
off!

Just because something is type accepted does not mean it is quality.

Hmm, perahps you are right.  These are the answers

The dupleser with the most off-freq rejection will be the one NOT 
connected to the Spectrum transmitter.

Replace the spectrum transmitter with a different manufacturer.

Yes, but with all the gas money you are losing on repeat trips to the
transmitter site, along with buying the best cables, duplexer, etc for the
package you probably won't be able to afford the analyzer.

That can be true, since the UHF Mastr Pro transmitter is a little picky about
it's tuning. If you are unfamilar with that transmitter or don't follow the
tuning procedure CORRECTLY, it can be a dirty transmitter.  Of course, any
transmitter can have that statement said.

If you had a couple UHF Mastr Pro transmitters that were dirty, I can

The Siouxland Amateur Radio Association in Sioux City, Iowa bought a used
Spectrum repeater on 2 meters about 3 years ago for something like $1100,
(with duplexer) fully operational.  I attended a meeting of the repeater
managers in Sioux City about 2 weeks ago & they were saying they wish they had
never bought it.  (I tried to tell them not to buy it but they ignored me!!)

Either you really like the under-dog, or you crave attention.  This issue had
been going on for MANY years.  There is NO WAY that Spectrum could NOT know of
their reputation. (Which ranks at about the same level as Genave FM gear & the
early Regency gear)

That is one of the major problems that causes bad repeaters, decisions of

Re: [RE: [Repeater-Builder] Motorola Syntor, any good?]

[JOHN MACKEY]

Poor management by amateur repeater operators has gotten MANY repeaters kicked
out of locations or barred repeaters from getting into good sites.

About a year ago, in Portland Oregon, a local electronics "engineer" claimed
that my repeater was causing interference to his repeater.  He offered to help
me "fix" my repeater and loan me "test equipment".  (He obviously didn't know
that I have plenty of my own REAL test equipment)  After my refusal to change,
he complained to the repeater coordination board (by co-incidence we were BOTH
board members!!)  Another board member came by to inspect my repeater station
& his. Finally, they figured out that HIS repeater had a receiver problem.  He
backed off, but didn't take me up on offers I gave to help fix his repeater or
loan test equipment!!!

Of course you are correct.  The sad part is how many times this has resulted
in giving hams a bad name by operating spurious equipment, or
not able to perform the way a piece of quality equipment should.  It isn't
hard to find a Mastr II for $30 at a ham swap meet!

[Repeater-Builder] A humorous ham related issue

[JOHN MACKEY]

A few days ago I was called for jury duty.  I arrived for jury duty a little
early, & was seated in a very large room with about 100 other people called
for jury that same day.

A short time later, I noticed the ARRL Division Director walk thru the door &
was being processed for jury duty.  I was a little surprised to see the ARRL
Division Director being processed as a jury person!!  I walked up & spoke to
him for a few minutes, he said it was the first time he had ever been called
for jury duty in his life.

He was dismissed by about 9:30 AM.  Apparently the fact that he was a 2 year
retired Judge for that SAME county after 34 years on the bench made one of the
lawyers want to dismiss him from serving on a jury

I have a pair of Motorola Zener diodes for a late 1960's broadcast
transmitter.  I am re-building something that another person modified to their
own perverted likeness.  Can anyone look in a book & tell me what the cathode
& anode are part 50M140ZB5?

Yea, I know I could ohm it out.  If nobody responds I'll probably do that by
using my personal one at home.  (This is at my work)  It is the 310 volt
supply for a 20KW broadcast transmitter.  They are 150 volt diodes stacked on
a resister to regulate the 310 volt supply.

Wrong.
The Mastr Pro came out several years BEFORE the Micor.

Re: [Re: [[Repeater-Builder] Re: GE Stuff.....]]

[JOHN MACKEY]

The Mastr Pro was a excellent radio, & still it's spec's are very good even by
today's standard.  I still have SEVERAL of the late model Mastr Pro's in
service as repeaters on 6 meters, 2 meters, and 440 MHz in Oregon &
Washington.  Their receivers hold up in the most harsh environments.  I have
no immediate plans of retiring my Mastr Pro repeaters. 

(Of course, the Micor is no slouch either - I have those on as repeaters in
Iowa)

Yea, I've seen that be much more of a problem with the older MastrPro's that
had the tube tripler.  The newer MastrPro's solid state tripler was rarely a
problem on the ones I worked with.

I never used the MastrPro for mobile service, I only used them for repeaters. 
Of course, I was then using the base/repeater power supply
(4A12).

Re: [[Repeater-Builder] Diplexer]

I have done basically the same thing at two different repeater sites. 
(one in Sioux City, Iowa & the other in Portland, Oregon) Oregon uses a GP-9 &
the Iowa uses the GP-15.  Both work excellent & use the the comet diplexer to
split between UHF & VHF.  

Remember to add together the power output of ALL transmitters connected to
that antenna and make sure that TOTAL figure is WELL UNDER the maximum power
rating for that antenna.

putting a 6 meter repeater on the air is going to be a lot more trouble 
compared to 2 meters or UHF.

I've been a ham 20 years and have put several repeaters on the air for 6
meters thru 440 MHz.

hmmm...  I would have to check my books, but didn't the low band
motran use a different channel element than the low band motrac
on transmit?  (Or did they BOTH use the TLN-1082?)

I can tell you with great certainty that the UHF motran used a different
channel element than the UHF motrac in BOTH transmit & receive.

But other than the transmitters & the UHF motran, all the motrac/motran
receivers used the same elements.

Paul-

Yes, for the Motrac hi-band & UHF there were the HHT, LHT, & MHT. Same for
lo-band except they never made the MHT in low-band.  Then, if I remember
right, the motrans (LLT & MSN) had a label that said "transistorized motrac".

SNIP

I had a few, a mix of both the half-duplex land mobile radio with the solid
state antenna switch and audio/squelch board AND the OTHER version of the
mobile phone with a duplexer and the board that did the signaling needed for
IMTS.

In my opinion the radio was really more of a UHF mobile phone that was
modified to be a land mobile radio which could ONLY be used on a repeater
since it was incapable of simplex.  The 12 channel option had to be pretty
cool at that time.

Do you know, did they ever make the land mobile T44MSN as an option to be a
FULL DUPLEX mobile?  It certainly wouldn't have been much more trouble to
provide that as an option.

The problem was that what motorola directed as the correct tuning tool was
usually not strong enough to do the job.  So then you had to use a metal

SNIP

I sold my last Mark XII/T44MSN/T1411/etc at the Rickreal ham swap meet several
years ago.  I had a lot of trouble getting the receivers to meet spec, &
usually had to settle for about 1.0 uV.  That was typical of receivers in
mobile telephone service, which usually were listening to very strong
(possibly simulcast) transmitters.  In typical land mobile, such receiver
sensitivity was usually unacceptable in a quality system.

I think, in that era of equipment, a person who wanted to be duplex would have
been FAR better off to use a Motrac or Mastr Pro & modify it for full duplex
operation with seperate antennas.  (Which is what you did, Neil - I saw both
your radios!)

The other problem with those radios, was the transmit PA.  It was a MSN 45
watt 150 MHz transmitter with a varacter tripler on the final output.
Not very efficient & slightly tricky to tune!! Also, the tuning of the
varactor was (of course) a capacitor & a metalic tuning tool was basically
needed for the necessary strength required to turn that capacitor.  If you
happen to accidentially short across the capacitor plates with your tuning
tool, you would blow the varactor diode.  Last time I checked probably 10
years ago, the cost of that diode was about $145 dollars using my discounted
pricing at Motorola

Rather than buy a new diode, I waited until the next Dayton Hamvention where I
bought a whole identical radio for about $10 or $20.  That night K7LJ & I
pulled out the varactor stage & trashed the rest of the radio.

The only other thing good in those readios was that they had a tunable
harmonic filter which worked well for using as a front end filter on frequency
agile radios.  Example: a 440 MHz remote base to cover a 10 MHz operating
range but filter out signals on other bands or more than 20 Mhz away.

Re: [[Repeater-Builder] Reverse Burst]

[JOHN MACKEY]

It was the Comm-Spec RB-1, and I am unhappy to 
hear that they no longer make it.  That was a standard
piece of equipment I put in to any repeater transmitter
I put on into service.

Last time I asked, they said they would had no
plans to discontinue that board.  

:(

I suppose their new TS-64 with reverse burst built
makes that board less needed.

Be aware, about 10 years ago I did some modifications
to the RB-1 board (to meet some special needs I had
for the timing & reverse encode) and I discovered that
there were a few components on that board which were not
in the factory supplied schematic.  I called engineering at 
Commspec & they confirmed there were parts missing in the
printed schematic.

The best thing you can do it use real repeater equipment like a Motorola Micor

I think your guess is probably much closer to the truth.

I doubt that is true.  I have 2 sites where I run the Comet GP-15 440/2m/6m
antenna on repeaters for 2 meters & 440 Mhz.  75 watts out of the 2 meter
duplexer & 45 watts out of the 440 duplexer thru about 60 feet of 7/8" heliax
has performed well for years.  As with any good installation, use QUALITY
receivers & transmitters, QUALITY jumpers (like RG-214), and good pass/reject
duplexers.  I have been able to make these systems work WITH ARR GaAsFET
pre-amps!!!  (If there was a noise or intermod problem, the pre-amps wouldn't
be working!!) Be prepared to put a pass can with sharp skirts on the receive
side output of your duplexer.

NOTE>> a quality receiver and transmitter basically dis-qualifies the
following: Icom, Yeasu, Standard, Uniden, Kenwood, Motorola GM-300, Azden,
Alinco.  The following would be considered quality: GE Mastr Pro, GE Mastr II,
GE Mastr Exec II (NOT the original Exec), GE Mastr III, Motorola Motrac,
Motorola Micor, Motorola MSR.

I always pull my systems Comet antennas apart & solder the connections.
Better yet, forget the Comet & Diamond antennas that have connections in the
antenna.  Get the Comet GP-15 from HRO for a little over $100, it is a one
piece antenna (no connections) and has worked very well for me.

Actually, it is best NOT to use Comet or Diamond antennas.  But sometimes the
situation dictates that you must.

Re: [Re: [Repeater-Builder] SWR between radio and duplexer]

Usually, a 110W transmitter running at 50w will draw MORE current & produce

Recently, I went in to RS for a simple device I knew they had.  Of course, the
worker there met me a few steps after walking in the door to ask how he could
help.  I told him what I wanted, & he said they didn't carry that anymore. 
Then I went looking on their racks & found several.

RS sorta reminds me of Les Schwab tires in the Pacific Northwest, as they both
have their employees come running up to greet you like your favorite pet dog. 
The typical RS employee knows about the same of electronics as Les Schwab & my
dog, too!!

In the 1980's, when I was in college, I applied for a pre-christmas time job
at RS. (I figured it would pay the bills until I found a real job) I was
interviewed, & later received a letter stating that I was not what they were
looking for in employees at RS.  Looking back on it, that was probably a
compliment.  I was soon hired by a FM broadcaster for engineering.

You can best modify the spectrum by replacing the following components:

Kevin - Does that tell you something when the manufacturer won't even support

Most of us here are running repeaters that are at least 15 years old.  Several
of my repeaters were built in the late 1960's & thru the 1970's by GE (the
Mastr Pro).

Thanks Gary, you are correct.  I might add, I have found
Spectrum equipment perform very well as door stops.

Kevin - if you don't have any money to put up a repeater, then you shouldn't
be doing it in the first place.  Repeaters are a HUGH money drain if you run
them in even lower quality.   

PSSSTT- You'll spend a lot of money in parts and buying people coffee/food to
help you keep that spectrum running.  They are crap.

Kevin, for that I applaud you!!!  Just a few weeks ago we had a person come on
this mail list, & ask about spectrum repeaters.  He was told all the horror
stories from many different people about all their problems.  Then he
announced that he thinks he can make one work using better technical standards
(or some foolish statement like that).

Re: [[Repeater-Builder] re: request for spectrum repair help]

[JOHN MACKEY]

Skipp -  Sure you occasionally have someone
who has had good luck with Spectrum equipment.
But the VAST MAJORITY of us have had BAD experiences
with the equipment.  BTW - we're not all dumb techs!!
Many of us have several years experience
in amateur radio, or make our living professionally
in the technical side of radio (or both).

Myself, I've been a ham for over 20 years, have worked
in the two-way radio field, have done communications tech
work in the military (& still do as a reservist), and
currently am the Chief Engineer in an FM broadcast station.

Re: [[Repeater-Builder] re: Kevin's spectrum equipment]

[JOHN MACKEY]

Skipp-

Nice saying, I may use it in the future!!

You are right, no one ever called me or anyone a
"dumb tech" in this exchange.  I was only heading off
the obvious thoughts of ONE person who (several weeks ago)
claimed he could make the Spectrum gear run correctly
when the rest of us said it was not a good idea.

I think you will find that most of us ARE "honestly"
trying to help Kevin out by recommending he find a different
piece of equipment rather than put time & effort into a 
Spectrum.  A Mastr Pro, Mastr II, Mitrek, or Micor can usually
be found cheap (or free if you look hard enough).

Re: [[Repeater-Builder] Repeater upgrade needed]

[JOHN MACKEY]

It seems like you were on here about a month ago telling us the same story and
asking the same questions..

Anyway, the BEST thing you could do is  to move the repeater antenna BELOW the
45KW of FM broadcast.  The micor receiver and band-pass filters are good &
there is probably nothing better you could do.

Is there any acceptable way to re-attach this to the casing or

The advice always is to turn off the extender/noise blanker in repeater

You are correct.  It was/is not the ENTIRE ORRC board that is less than

Re: [Repeater-Builder] Re: 10 meter desense help, split site, high noise floor.

[JOHN MACKEY]

Comm-spec even gives instructions on how to make CTCSS work on AM CB radios!

Really, 10 FM radios are so plentiful, that uncertainty regarding how well a
converted CB would work with CTCSS is not practical.  Besides, I'll bet the
bigger technical challenge would be to get a converted CB to do 100KHz
offsets.

Re: [Repeater-Builder] Re: 10 meter desense help, split site, high noise floor.

[JOHN MACKEY]

It seems that someone once told me that in the early days of 10 meter FM the
first repeaters were all 29.60 input and 29.69 output, this allowed for people
to only need an additional receive channel if they already operated simplex.

Bob- You are probably correct that the FCC would suggest it be left to
coordination.  But that has been the plan for the last 25 years, and we see
that it is a failure.  I few dim-wits refusing to use CTCSS spoil it for
everyone.

Re: [Repeater-Builder] Re: 10 meter desense help, split site, high noise floor.

[JOHN MACKEY]

So if the transmit offset for a CB radio was overcome, and converting from AM
to FM for a CB radio 
was overcome, adding CTCSS is a simple issue that will be easily overcome.

The problem with your idea of "I'd just rather shut the repeater down during
band openings" is that plan just never seems to work.  Guys are good about
doing it for a while, then the persistance fades away (I've seen that MANY
times)

Re: [Repeater-Builder] Re: 10 meter desense help, split site, high noise floor.

[JOHN MACKEY]

Here in Portland, Oregon we have group that has about 4-5 two meter repeaters
all linked together.  They seem to think they need that many repeaters just to
cover the metro area.  Their repeaters usually have TERRIBLE sounding audio
and often have squelching problems.  The main person who operates this system
sits on the repeater coordination council and keeps scamming more repeater
pairs for his group every couple years.  Here is their link:
http://www.worc.info/worc_system.htm

Often times, their repeaters sit idle.

Mean while, the waiting list keeps growing.

Re: [Repeater-Builder] Re: 10 meter desense help, split site, high noise floor.

[JOHN MACKEY]

NOBODY (including the FCC) cares what the ARRL's stand is  They are so
far
out of reality so often on things like this that few listen.  I have a 
repeater with a 10 meter FM remote base that has been running
for nearly 10 years, and many have been doing in LONG before me.

I am an OO, and I would never give this issue a second thought.

If it were illegal, Riley would have jumped on it a long time ago.

Heck, until a few years ago the ARRL was calling 29.600 the "calling channel"
which shows how little they know!

Re: [Repeater-Builder] UHF duplexers and preamps

[JOHN MACKEY]

Hi Nate-

You are correct, you don't know the situation.  There are plenty of systems
that provide good metro coverage with 1 or maybe 2 repeaters here in
Portland.

Simply put, these people don't play nice.  They often make their gain by
character assination, and have a lengthy record seen by several people.

The squelching problem is repeater receivers blowing squelch noise for on a
regular basis for months, I call that serious!  The audio has often sounded
poor to bad in the past, I call that cosmetic.

I don't chose to talk on the repeaters.  Once, about years ago I allowed my
son to talk on their repeater
using my callsign with me there as the control op.  He was having a plesant
conversation with someone there
and the system was then shut down.  The repeater owner statements made it
clear he did not like a youngster using 
their repeater.  That is hardly what I call good amateur practice.

The last time I was in Denver, I had no problem finding inactive 2 meter
repeaters to talk to
NP4AI on.

Because digital TV broadcasting can cram multiple viewing channels in that

Not exactly true.

Analog operation for TV in metro areas will cease in Feb 2009.  LPTV and
translators that are analog will be allowed to continue operating and
currently have no sunset time.

Re: [Repeater-Builder] FW: Dayton and Parts you might need....

[JOHN MACKEY]

It has been a problem every year since I started attending Dayton, which was
1987. The more attention you give it, the more it happens.

Every few years there is an announcement that the jammer has been caught. Then
the next year it starts all over again.

Yea, call Riley!!!  RRIIIGHT!!!

One year after Hamvention myself and another ham were driving east on I-70 to
catch a plane at Columbus and were were driving about 67 MPH.  A SUV with
call-plates that match Riley's callsign went speeding past us, at probably
something like 80 MPH.

RE: [Repeater-Builder] coordination?

[JOHN MACKEY]

Thanks for the preaching, Mike!!   You are a previous chair of the Oregon
Region Relay Council.

Now I'll take my turn on the soapbox!

I have several different repeaters coordinated across 4 different repeater
coordination councils in 3 different states.  Oregon is by far the most
schrewed up and fully supportive of the "good old boy" style of repeater
coordination by applying rules selectively.  Yes, I took my turn and tried to
fix the situation, by being on the coordination council board 4 different
times, once as an officer of the board (Secretary).  Mike, I am glad you feel
the system works.  There are many who disagree with you.  The fact that in the
last 10 years 3 other coordination bodies have started in Oregon says
something.

Since I work in the commercial radio field, I have experience with
professional coordination.  It works much better than amateur.

I feel Ron & Paul's idea is a good one!
