No, I agree with you. It's getting worse out there. The odds are greater and 
greater that interference is coming to a repeater near you.

[Repeater-Builder] Weinschel Attenuator Housing

[ldgelectronics]

Does anyone need a Weinschel 45-10-33 attenuator housing for free? It 
does not have any resistor elements in it. 

Not sure why I still have it, so it's going in the dumpster unless 
someone has a need for it.

The best odds of getting a Petition for Rule Making accepted for

[Repeater-Builder] DB4048 rework - finally

[lcradio2002]

Well, I was finally able to rework my 150's band DB4048 duplexer down
to 2m.  I built some new longer loops as per the info on the RB
website, and I fabbed up all new 12.5" RG214 coaxes.  Now, the iso
(i.e. the notch) is around 81dB, and the insertion loss is around
1.4dB.  I think these are within specs.

My question lies in the original layout of the duplexer.  Originally,
on the side with the 1/4 wave transformers, at the duplexer can there
was a TEE, and a shorted stub was connected there.  All three on that
side had these stubs.  The conversion article does not mention using
them, although the final picture shows them there.  There is no
mention of using them, so I removed them.

Any idea what they are really for?

I have one here.  The box is simply that.  All three cables are soldered 
together in the box in the form of a "T"
Rx one side, TX other side and the antenna is the center leg of the "T".

Glenn,

Yeah, I wonder about what's in the box too, but I suspect it's simply a
place to solder the three center conductors together, and the impedance bump
is ignored.

So, what you need seems to be a TLE5772A "Yellow" tee cable assembly.
Wouldn't it be great if someone who has that cable could make exact
measurements of it, just as Charlie KC5OZH did for the TLE5732A "Green"
cable?  I'd rather not make up such a cable harness with an N tee and N
connectors attaching to it, but I might not have a choice- and it should
work.

[Repeater-Builder] Re: MSF5000 TEE Cable

[Bill Powell]

I'm hoping to get an MSF up on UHF as soon as the current owner
declares it "scrap".

Since it is currently configured as a base station I'll have to come
up with a duplexer.  On a recent visit to a local Moto shop I spotted
a MSF UHF internal duplexer that was up for grabs.  Unfortunately -
other than knowing it is "UHF", I don't recall the band split.  So I
just sent off an E-Mail asking for the cable color along with a query
about the mystery Yellow cable.  If he can lay hands on one I'll make
precise measurements and photos and share them.

However, from that one quick examination, it is obvious that the
exciter to amp filter is a pass filter to reduce the exciter broadband
noise and the transmitter (amp) output "filter" in the "duplexer"
provides only a deep notch at the RX frequency and is not a
"transmitter filter" per se. In shared sites I try to have at least
one big (high Q) pass can in the TX output, just to be a good neighbor
and the MSF internal "duplexer" doesn't qualify.

As far as the cables go, it would seem to me that the cable length
needs to be such as to transfer a minimum of the transmitter RF to the
receiver port when properly terminated.  This would then be an odd
multiple of 1/4 waves at the transmit frequency between the
transmitter and the antenna and an even multiple of 1/2 waves at the
receive frequency between the transmitter and receiver.  (or did I
manage to get that perversed?).

In any case, I have heard that, on a good day, with a tail wind, the
internal "duplexer" just barely manages to make "spec".  With ANY sort
of antenna issues (ice, wind, water in the jumper) the receiver gets
desensed. So - when I actually lay hands on the MSF I'll be shopping
for a "real" duplexer.

RE: [Repeater-Builder] Re: "Cheap" P25 repeater ...

[John Barrett]

*flame on*

 

So what ?? so what about folks like me that don't want to lay out $1000 for
a 1.2ghz DSTAR data radio, or who would like to operate DSTAR using SDR
gear. What about PACTOR3 - plenty of decoders, but if you write an encoder,
the folks that came up with it land on you like a ton of bricks

 

Kind of defeats the spirit of experimentation and innovation that has been
part of the hobby for so long.

 

But I guess not too many people care any more - they want plug and play
instant gratification - and picking up a soldering iron or reading a
schematic just doesn't cut it. "put the green cable in the green socket" is
about as technical as they can get.

 

*flame off* 

 

I'm going back to wiring up my 80 amp power system and 2000ah battery backup
array for the shack.. gotta love rural power.. we lose it at least twice a
week :-)

I don't see why not. 

Hams all over the country are experimenting with a variety of 
digital voice formats including D-Star, P25, AOR, FDMDV, and 
Mototrbo TDMA. If some of these are only available from one 
manufacturer - so what?

Since this list is not for rules debate - let's just build some

It is as you would expect - a simple open area that you solder the three 
center conductors together and then replace the side cover. We rebuilt a 
couple of them from lo TX to hi TX a few years ago, but did not keep the 
dimensions (oops).

[Repeater-Builder] 222 MHz Karaoke Mic on the Repeater Input Frequency Story

[skipp025]

Not that we didn't think about it...  but the wireless mic 
is wide-band fm whereas the repeater is a typical communications 
audio more narrow band operation. So they really wouldn't 
be able to hear our radio transmissions that well/loud. 

The owner of the Karaoke system has about 5 to 7 mics he rotates 
through people standing in line to sing (a scary thought unto 
itself).  When the 222 MHz mic was unused he would set it on 
the table and we were able to hear everything going on in the 
bar as long as the audio didn't get too loud and pop out of the 
repeater receiver IF Bandwidth. 

So a friend and I df'd the problem to a bar... 

After a big of introduction and soft politics I encouraged the 
operator to mark and avoid using the 222 MHz micrphone by 
demo'ing how his equipment responded very poorly to my in hand 
222 Icom HT transmissions. 

I mentioned that his simply not using the 222 MHz mic would more 
prudent than hearing some packet sounding test tones through 
his equipment during working/show hours. 

To be a nice guy I even offered to re-crystal his mic and 
receiver (at my cost) and handed him my card before leaving. 

So far the problem hasn't returned.

Hi Eric
I agree on the tee connection in the center being the tricky part. I wonder
also if there is anything else that Moto has put into that small box in the
middle of the tee. Or could a person just use a regular tee connector and
then make up 3 jumpers with connectors on each end and just connect up to
the tee. Problem is that after you get done buying all the connectors and
the tee to make one yourself, especially if they were type N, you would be
at least halfway towards just picking up a new one. 

I have not seen these in VHF, since the only MSF5000 stations that were able
to use a completely internal "duplexer setup" were the UHF ones that used
the high selectivity optional front end receiver filtering combined with the
3 section prefilter and then the 4 section post filter on the transmit amp,
all feeding into the special tuned TEE cable. It all seems sort of a kluge
but it does work and you can run the repeater off a single antenna without
an
external standard duplexer. They claim about 75-80 dB isol at 5 MHz
separation if tuned right. It has been mentioned that some people have had

Glenn,

I perused the MSF5000 section on the RBTIP and found a sheet titled
"Combining Tee Duplexer" which addresses only the UHF tee cables. I suppose
there is another sheet somewhere that documents the VHF tee cables.

The above sheet states that the TX leg on a TX-below-RX cable should be
about 1/4 wavelength, and the RX leg should be about 5/4 wavelength.
However, the dimensions shown for a green tee cable on a file recently
uploaded by KC5OZH, do not agree with the above statement. It appears that
Charlie's drawing is of a TLE5732A cable.

One-quarter wavelength is about 17 cm at 435 MHz, and about 16 cm at 475
MHz. Likewise, 5/4 wavelength is about 86 cm at 435 MHz, and about 79 cm at
475 MHz. Based upon Charlie's measurements, it would seem that the formulas
given in the Combining Tee Duplexer sheet are incorrect.

I believe that fabrication of the tee cables with RG-400 coaxial cable and
readily-available crimp connectors is a simple task. What may be a challenge
is making the tee junction without a significant impedance bump.
I'd prefer to use a constant-impedance tee, but such an animal may not be
available in a three-way (cable-cable-cable) configuration.

I misunderstood.  I thought you meant you were looking for a three-way
female tee so you didn't have to use an intermediary female-female barrel
adapter on the middle (antenna) port if you were stuck using a conventional
female-male-female tee.  When you said "cable-cable-cable" I was thinking of
three cable ends each with a male N on it; "crimp-crimp-crimp" makes it
clear what you were looking for...

You could probably homebrew the equivlent of the Motorola "tee box" using
some copper stock soldered together.  Even run-of-the-mill copper strap
tin-snipped to the appropriate size and soft-soldered together to make the
box would be adequately strong from a mechanical standpoint.  The braid of
the RG400/RG142B could get soldered at the thru-holes punched in the
"sides", with the center conductors joined inside the center of the box.
While eliminating extra connector junctions is generally a good thing, type
N's have negligible loss at UHF so it might not be worth the effort as
compared to using an off-the-shelf connectorized solution.

RE: [Repeater-Builder] MSF5000 TEE Cable

[Eric Lemmon]

Jeff,

I am well aware of the Delta tees used on Sinclair duplexers, but those
incorporate one or more N plugs.  My comment clearly stated that a three-way
crimp tee (that is, crimp-crimp-crimp) was not readily available.  I suppose
that I could use one of the Delta tees, along with a short jumper that has N
connectors on each end, but that is not a duplicate of the Motorola tee
cable.  One reason I use crimp devices exclusively is to eliminate, wherever
possible, additional connectors or adapters.

As for the odd lengths of cable in the tee harness, I agree that the
dimensions don't seem to make sense.

I'm not sure why it would matter whether the Tx freq was above or below the
Rx freq given the minor (and generally negligible) differences in length for
a 5 MHz split, nor why it would matter whether the 1/4 wave vs 5/4 wave was
on the Tx vs Rx since, from an impedance transformation standpoint, they're
the same. For the latter, is it just a mechanical issue (i.e. would the tee
come out at a more advantageous physical location with one orientation
versus another)? Or am I missing something?

Triple-female tees are readily available, standard part number UG-28A/U:

RF Industries RFN-1011-1
Amphenol 82-99
Delta UG-28A/U

You can also get "in line" tees that crimp directly onto the cable for two
of the ports (Sinclair et al use these in their duplexer harnesses):

Delta 1185-019-A551 (for RG142B or RG400)

RE: [Repeater-Builder] MSF5000 TEE Cable

[Eric Lemmon]

Glenn,

I perused the MSF5000 section on the RBTIP and found a sheet titled
"Combining Tee Duplexer" which addresses only the UHF tee cables.  I suppose
there is another sheet somewhere that documents the VHF tee cables.

The above sheet states that the TX leg on a TX-below-RX cable should be
about 1/4 wavelength, and the RX leg should be about 5/4 wavelength.
However, the dimensions shown for a green tee cable on a file recently
uploaded by KC5OZH, do not agree with the above statement.  It appears that
Charlie's drawing is of a TLE5732A cable.

One-quarter wavelength is about 17 cm at 435 MHz, and about 16 cm at 475
MHz.  Likewise, 5/4 wavelength is about 86 cm at 435 MHz, and about 79 cm at
475 MHz.  Based upon Charlie's measurements, it would seem that the formulas
given in the Combining Tee Duplexer sheet are incorrect.

I believe that fabrication of the tee cables with RG-400 coaxial cable and
readily-available crimp connectors is a simple task.  What may be a
challenge is making the tee junction without a significant impedance bump.
I'd prefer to use a constant-impedance tee, but such an animal may not be
available in a three-way (cable-cable-cable) configuration.

Re: [Repeater-Builder] Re: New QRM on 220 MHz.......?

[Steve Smith]

Key up on the frequency of the mike and loudly say "This is the devil, I hear 
you and I am coming."


Number two in the hit-parade is the Karaoke Mics that pop up on 
the input to some repeaters... I happen to be the lucky one here 
in Northern California.  A 9-volt battery powered mic reaches my 
5+ miles distant high level repeater site quite well. The only 
song request we've made is to track the user/owner down and ask 
that he stop using that mic, which so far has worked quite well. 

RE: [Repeater-Builder] Re: Micor Repeater (i hope)

[Jeff DePolo]

 
A couple of basic things come to mind:

1.  Do you have the PL encoder plugged into the exciter?  If not, did you
install the jumper in the exciter board?

2.  Did the station originally have the F1-PL card?  It provides one (or
more) keying voltages, but I'm not in the office and I don't remember which
for sure, but it may be oscillator ground or one of the "keyed" voltages.

The fact that you see PA power start to come up but then it dies shortly
thereafter almost makes it sound like it's NOT a control logic problem, but
then later you said that you're missing keyed A- so that contradicts that
notion.  As a test, "pull up" the PA power control line to A+ through a
low-resistance (say, 4.7 ohms), key the station, and then while it's still
keyed, disconnect the pull-up.  Does it continue to make power, or does it
drop out?

The power control board will shut down the PA by killing control voltage if
it doesn't see power output come up fast enough; I'm wondering if that's
what you're experiencing.  You could have a bad diode or other problem in
the antenna network which results in the power control board thinking there
is a PA problem so it shuts it down.  Put a voltmeter on the sense voltage
lines going to the power control board to verify they're good (you'll have
to "pull up" the control voltage to get the PA to make power to take those
measurements).

By the way, are you using the stock supply or something else?  And which PA
(power level) do you have?

If you can't get it to fly, drop me a private email and I'll get out the
"orange book" to refresh my memory on the keying logic next time I'm in the
office.

I think it's safe to say "If you haven't been hit by an interference 
problem, your turn is coming." It doesn't matter what part of the spectrum 
you are talking about or whether it's commercial, broadcast or ham. Consider 
yourself lucky if you've avoided it so far.

[Repeater-Builder] Re: New QRM on 220 MHz.......?

[skipp025]

Three or four major sources of 220 QRM happen in my area. The first 
major source is actually not a problem... but is actually a technical 
issue with many of the ham radio receivers. The 224 Amateur band 
is a pretty good IF Image for the adjacent TV channel.  So yes, we 
can listen to the daytime soaps on the classic Icom 3at hand-held 
radios without trying hard.  Most of us deal with it by hopefully 
living far enough away from the TV transmitter that simply turning 
up the squelch provides some measure of relief. Otherwise something 
like a DCI band-pass filter might be helpful. 

Number two in the hit-parade is the Karaoke Mics that pop up on 
the input to some repeaters... I happen to be the lucky one here 
in Northern California.  A 9-volt battery powered mic reaches my 
5+ miles distant high level repeater site quite well. The only 
song request we've made is to track the user/owner down and ask 
that he stop using that mic, which so far has worked quite well. 

Number three is the pesky parrot simplex repeater parked on the 
repeater input... we have another one on the air causing problems 
in our area. We're trying to deal with that right now... so that 
saga continues. 

Number four is some data telemetry that often sounds like chirping 
or soft CW. We found the problem signal location and contacted the 
area comm-shop who removed it without ever admitting the problem 
or acknowledging it was there. We found the signal was traced back 
to some unlicensed telemetry equipment used by a water service. 

I have not received much of a problem from any of the remaining 
220 Band ACSB trunking equipment. 

So there ya go...

Al,

I've got the full chasis for a VHF repeater with everything (receiver,  
controller, exciter, low power PA),  I do not have the external Power  
supply, but have managed to get it powered up by applying power to the  
correct connector (minus the 5v on the connector).  I was wondering if  
a VHF amp of any type would work for the high power PA?

[Repeater-Builder] Re: Duplex a Mitrek and/or MSR-2000 CTCSS "PL" Board

[skipp025]

Not the exact answer you want Eric... but at least some information 
is better than none. 

I've been able to duplex a number of Mitrek and MSR-2000 Modules 
that were originally supplied/sold as standard half-duplex circuits. 

Don't know the details about the reedless ctcss board... 

The trick is to look at the actual circuit.  Duplex operation 
requires two of the ic chip sets used to create the encode and decode 
functions. If a module was able to cross-code tones or has the 
pc board holes and parts placement locations then it probably 
can be duplexed if the encode/decode sections can be separated 
out. 

I've been able to duplex the cross-code CTCSS boards and modules 
that were sold half duplex by populating the board using surplus 
parts. In the case of the MSR-2000 CTCSS Module... I simply used 
the IC chips removed from the Mitrek Mobile CTCSS Board. The 
standard ctcss board in the Mitrek uses the same chip as the MSR- 
2000 Repeater/base Station although they have different part 
numbers (go figure...). 

So take a look at the board to see if the pc-board will allow 
cross coding ctcss/dcs as your first clue.

Ah and guess what Motorola has changed that yet again on the new Quantro's.  
Now the new Quantro's use the standard 100 watt internal PA throttled back to 
drive just one single high power PA to get up to 350 watts.  No more two 
external PA's on the Quantro's.

Needs to have the proper PA if you want it to operate properly.  Quantro PA's 
are different than the Quantar PA's and are more like an MSF 5000 PA in the 
final stage.  Quantro's usually just have a low power PA that is fed from the 
exciter.  This is then fed to the high power PA to get your final drive.  I've 
tried it in the past and it just doesn't work correctly.  What do you have 
right now for a Quantro and what is it missing?  Might have parts for you.

[Repeater-Builder] MSF 5000 Magic "T" Cable

[w7hsg]

I have built up 2 MSF 5000 and help maintain another. Even with the correct 
cable, isolation (desense) of the MSF system is not good (about .25 microvolt 
measured.
So far, all of our systems use the stock MSF filters feeding a good duplexer 
such as the Motorola 4 can pass notch or PD 500 series.
I have played with varying the lengths of the arms and main branch.  We use RX 
low and TX high  (all 440 systems)

RE: [Repeater-Builder] Re: Micor Repeater (i hope)

[w7hsg]

Eric and anyone else interested.
I don't know where the MSR 2000 came from.  This is a micor, looks like a micor 
and uses micor modules/receiver etc
The following is the information requested
TLN 4635 Station Control
TLN 4662 Squelch Gate
TLN 4669 Line Driver
TRN 4860 A (84E82352N01) backplane
Modified backplane as follows
added + & -13.8VDC to TB 2
added jumper between Pin 6 and 14 on the RX interface board.

Ralph,

Maybe I'm missing something here, but is your station a Micor, or is it an
MSR2000?  Your subject line and the attachment do not agree.

Please advise what backplane you have- there is more than one and they have
significant differences.  It is always helpful to identify the part numbers
(usually stamped in black ink) of each module, so that we all know what you
have.  Some modules only work with specific backplanes.

Hi All
Building a Micor Repeater from Scratch

Facts.
Mother Board (unified Chassis ) origin unknown. Had to add a jumper for
+12Volt to RX.

Rx with audio works fine. Not using pl board ( control system does PL)
Have great local speaker vol and squelch.

Exciter, Tripler, PA and circulator all are in working order 

Have the following modules in the following slots counting from the right
front.

Audio Line Driver Slot 1
Station Control in Slot 2
Squelch gate in Slot 7

I can Key the transmit on the station control module 
The exciter and tripler key up and make power
PA power comes up about 2 watts and drops off
Power Control module check out in a known good complete Micor repeater.
Control Transistor is good and plugged in correctly. Checked voltages 
Missing (- A Key ) minus A Key on the control module.
Station Control Module (-A key ) does NOT come up.
Station Control Module works in a known good micor repeater.

I can add +12 volt to PA control terminal on the PA and PA makes lots of
Power on the correct frequency but that bypasses the Circulator SWR protect
etc 

The intent of the whole mess is to use the minimum of the Motorala modules
since the 
Sierra Radio Control system has provisions for Squelch, PTT, RX and TX pl
etc

any Ideas??

   For the People who are having Interference Problems on 220 ,  You might want 
to Check around the Walgreen Stores that have put up the New Electronic signs.  
I Have a Repeater on 224.740 and a few of the Stores if I am in the Parking lot 
or get within a block I have a Full scale reading on the output 224.740



  A related story to this Months back  a Local FD was using their simplex Freq 
of 153.890 at a Fire  Near a Walgreen's  that had the New Sign,  and the 
Fireman could not hear their Dispatcher . An Investigation was done and it was 
found that the New sign was putting out a carrier on that freq . 



  Walgreen's were notified and the Problem was fixed  by some filtering , I  
Took some Equipment  out about 3 in the Morning to 5 Local Walgreen's and the 3 
that had the New Sign ,  I had Spurs all over the Place 130-470 Mhz .  I Was 
also informed by another Ham who had  helped with the FD Problem  and He gave 
Me some Walgreen Contact Numbers but I never did pursue It  , I don't have any 
users who live by a Walgreen's  but they all have the Problem in their Mobiles 
as they drive By . I don't know if this is a Widespread problem or not but 
other users can check it out too and see. 



  Happy and Safe New Year to All

Re: [Repeater-Builder] MSF5000 Tee Cable

[Bob M.]

The short end with the male N connector goes to the
internal filter/duplexer (i.e. transmitter output).
The short end with the female N bulkhead connector
goes to the station junction panel and out to the
antenna. The long end with the right-angle male SMA
connector goes to the receiver input.

It looks like RG400, and since the receiver is on
slide trays, that cable has to be somewhat flexible.

There are plenty of photos of a UHF MSF repeater on
repeater-builder. I guess very few people in this
group ever heard of that site, much less read articles
there. I'll say it once - for the last time in 2007 -
it's aggravating to hear that people are too lazy to
search for, and read, information on the web. Maybe
it's an "ego" thing.

Re: [Repeater-Builder] Re: "Cheap" P25 repeater ...

[Albert]

Needs to have the proper PA if you want it to operate properly.  Quantro 
PA's are different than the
Quantar PA's and are more like an MSF 5000 PA in the final stage.  
Quantro's usually just have a
low power PA that is fed from the exciter.  This is then fed to the 
high power PA to get your final drive.
I've tried it in the past and it just doesn't work correctly.  What do 
you have right now for a Quantro

and what is it missing?  Might have parts for you.
