Anyone else getting multiple copies of the same email on any or all of
their subscribed Yahoo Groups?

I'm seeing as many as 10-12 exact duplicates showing one time stamp then
the same exact email 6-8 times at a different time stamp.

I do & a grammar checker also.  I try to make what I write readable.
Writing without capitals, punctuation, & spacing is unreadable.  I just
delete it most of the time.

There are three ratings of PP that all use the same size shell. These
are the 40 Amp, 30 Amp, and I believe the third is 15 or 20 Amp. Most of
the ones you see sold are the 30 Amp version. The 40A is built obviously
heavier than the other two.

My previous comments were all relative to the 30A version.

RE: [Repeater-Builder] Re: Power-Pole connectors NOT for power

I've never had an issue with the bodies coming apart.  When I slide them
together they're a pain to get apart.  I read some place that some CA. ARIES
groups decided to reverse the standard polarity.  One may not want to glue
your go box radio connecters.

I've seen poorly made Chinese made clones that were junk, and I've
seen the real Andersons that almost needed Channelocks to pull apart.
I've also seen ones with defective plating and insufficient spring tension
get so hot they melted the bodies.

You get what you pay for.  If all you've seen is the clones, then you
experience will tell you that yes, they are junk.

BTW the Johnson 8655 900mhz mobiles have a set of chassis mount
Powerpoles mounted in the back panel. Really surprised me the first
time I saw them.

And Eric's suggestion about pre-gluing the bodies is a good idea.

What is the problem?  The directions say, "Push in until they click".  How
hard is that?  The little ones go together just like the big ones.   Anybody
with one eye and half sense can do it.  They are the greatest thing to come

I second that.

I myself have found these little power pole connectors (which are  
recommended by emergency groups) to be a bit too delicate for me. And  
if improperly built, will have little or almost no contact tension at  
all. Honestly I was a little shocked when I started seeing these  
little buggers marketed for emergency amateur radio purposes. The  
bright side I see in that is everyone can connect with minimal fuss.  
But if the connectors were improperly built, I wouldn't be surprised  
to see a few of these tapped up during a real disaster in order to  
keep them from falling out of their other mating half.

For years, I myself have utilized the larger SB 50A Anderson  
connectors on my primary Amateur Radio (TS-450 / IC-910) and Solar  
system at my home QTH. Now try and pull those babies apart. Talk  
about contact tension. You can't accidently tug on you power harness  
and pull these apart.

One more thing, my jaw dropped when I had built my K2-100W. It uses a  
chassis mount variant of the tiny power pole connectors out from the  
rear of the unit.

Well, just my two cents.

Yes, they do, and they are quite happy to charge over $100 for it.

In that article Kevin shows you how to do the same thing for
under $10.

Yes, it's uncalibrated, but a counter doesn't care.

And if you really want to get a calibration on your home-brew one,
it's not that hard to measure the insertion loss.

delivered with a "combination manual" that comprised as many as 12 separate
LBI documents collected into one binder.  Each of the individual LBIs was
selected, based upon the specific modules in the radio.  Since each radio
might have any one of four or five difference transmitters, exciters, power
amplifiers, decoders, receivers, etc., each manual was different.  Moreover,
the manual you need for your specific radio is based upon each of the
modules contained in your radio- and may be unlike any other radio.

Please advise exactly what radio you have, by the Combination Number, or by
a list of module numbers appearing on each PCB module.  The chances are good
that the Master LBI Index contains each of the LBIs you need to put together
a complete manual that covers your specific radio.

73, Eric Lemmon WB6FLY

RE: [SPAM] [Repeater-Builder] Flat Audio

[Fred Flowers]

Shorty,

I use GE Mastr II repeaters & Mastr II mobiles for links.  All these "flat
audio" modifications are a waste of time.  We have over 4 hops of links.
The difference in simplex & duplex audio, if any, ain't enough to worry
about.  I don't understand the need to carve on perfectly good radios,
designed by engineers a whole lot smarter than I, & gain very little in the
real world. 

 

Time & money can be put to better use on the real important stuff like
antennas, duplexers, feed line, controller, & a good repeater to start with.


 

I think sometimes modifications are done just for the sake of modifications.

Subject: [SPAM] [Repeater-Builder] Flat Audio

 

Hi Group,

 

Some comments of the flat audio thread...

 

Flat Audio through a repeater simply means that the repeater does not mess
with the audio through-put.  The End-to-End audio path is flat through the
repeater.  There is no de-emphasis or pre-emphasis going on inside the
repeater audio path.  The repeater receiver leaves the audio alone, the
controller leaves it alone, and the repeater transmitter leaves it alone.

 

One of the tests that should be performed on every repeater is to test the
audio frequency response through the repeater.  A signal generator should be
connected to the repeater receiver, and a full-quieting 1 kHz tone should be
sent into the receiver, at say 3 kHz deviation.  The repeater transmitter
should be adjusted to also be transmitting 3 kHz of deviation, as measured
on a service monitor.

 

Then the audio frequency should be swept between 300 Hz and 3000 Hz in 100
Hz steps on the signal generator, and the transmitter deviation should not
vary more than 1% or 2% from the 3 kHz deviation as viewed on the service
monitor.

 

That is flat audio through a repeater.

 

In practical real-world service, every users transmitter pre-emphasizes the
audio on transmit, and every users radio de-emphasizes the audio on receive.
The repeater should leave the through-put audio alone, and your repeater
will sound just like simplex does.  No audio processing should be done
inside the repeater, period.

I was with ya, right up until you claimed that linking technology
should be compared to dorky recordings of The Three Stooges.

I agree WAV file sound effects, especially if you have to PAY to add
them to a repeater, are useless, and make the system sound "hammy".

IRLP and EchoLink, however...  are just linking technologies... they
tend to attract just about EVERYONE, twits included... you take the
good with the bad in that case.

[Sarcasm on...]

The only people I've noticed IRLP or EchoLink driving away -- are
people who haven't had a measurable pulse since around 1968.  We keep
a couple "quiet" repeaters for those folks.

Unfortunately some of our quietest machines are on UHF, and many of
them feel that band is out of their technical reach, since their
mono-band VHF rig without CTCSS has been operating "so well for all
these years".  And UHF is so high up there anyway, perhaps they might
find it difficult to tune an antenna for that band...

Use a DB-408 the mast is the same size top & bottom.  Hang it right side up
from the top.  You'll most likely be happier with the 408.  The beam with is
fatter.  It will fill in holes in your coverage area better.  The 420 has 3
dB more gain, however this will just help a little way out & hurt your

Subject: [Repeater-Builder] Effects of doubling RF output on UHF repeater?

One of our 70cm Amateur Radio repeaters is currently outputting 50 
watts into the duplexer.  We're considering replacing the existing RF 
power amp with a 100 watt model.

Current draw on the 50 watt unit is 8 amps.  The 100 watt unit will 
draw 20 amps.  Our power supply is rated at 36 amps continuous, and 
the duplexer is rated at 250 watts.

Half of our users believe that the repeater's output power is 
perfectly matched to its receiver.  That is, users of high powered 
mobile radios generally lose repeater reception at about the same 
time the repeater's receiver loses them.

However, the other half of our users believe doubling the repeater's 
power output would generate increased activity since the repeater 
could be heard more "comfortably."

We could upgrade without changing any of our other infrastructure.  
However, these questions arise:  1) Will the hundreds we pay to 
upgrade actually translate into significantly increased range?  2) 
Will we risk generating additional receiver noise by doubling our 
output power, thus losing coverage in the process?  3) Will using a 
higher power level shorten the life of other system components over 
time (e.g., power supply)?

By the way, our frequency coordination would be valid even if we 
doubled our output power.

Have a customer with the following issue:

xmtr site.

Issue: Very low level audio of radio station appears on Mastr II's 
xmtr (yes, external controller). Repeater owner hasn't fully

Question: The only way I see this happening is due to some AM

RE: [Repeater-Builder] Re: Combining antennas.

[Fred Flowers]

Skipp,
Thanks for the reply.  As I stated, I need to maintain a low profile.  There
is a 2 meter & 7/8" line on the tower.  The antenna is too high in
frequency; therefore the return loss from the antenna is about 4dB.  I have
a DB-224E that I'm going to replace the one on the tower with.  I also have
a DB-408 & a desire to put up a 440 repeater.  You can see where I'm going.


Can you recommend a good commercial diplexer?  I have a Maxrad.  Pictures of
what you did would be helpful if it's convenient.

Well yes... I'm doing it. They use the same mast but not the 
same feedline. If you needed to use a common feedline I would 
look at a commercial diplexer first... mostly for the higher 
power level capacity. I've used Comet and Diamond with great 
results... but any bad reflected power might cause the diplexer 
to fail... besided the failed antenna and diplexer you had better 
provide protection for the PA unless you're into amplifier 
repairs and/or replacement. 

The combo ends up being a lot of metal on one mast... so you had 
better be ready to properly deal with the installation. The ant 
assembly ends up being pretty darn heavy.

I didn't want to deal with the extra diplexer hardware/loss so 
I ran two feedlines. But I wouldn't have a problem using a good 
quality diplexer and upgrade the Hardline to the next size up.

Fred,

I have heard they are not really good for depleting but I have used a knock
off of a dual band antenna on my two repeaters when it was on my 60 foot
tower at my house, it worked good enough but now on my commercial site I use
the DB antennas.  I only have 12 antennas up there right now, the tower was
engineered for 42 DB folded dipole style antennas.

It would be interesting to test one at the 400 foot transmit platform if it
were not so expensive to get them up there.

Fred,

DB Products used to make, probably still do, a antenna just like you
described.  Just need a crossband coupler mounted at the antenna or two
coaxes going to your equipment.  Works well, don't use a cheap crossband
coupler though.  Buy a commercial grade one and you will be happy.

RE: [SPAM] RE: [Repeater-Builder] Combining antennas.

[Fred Flowers]

That is my understanding, however DB products have been bought out & I think
the whole line will be or has been discontinued.  I'm wondering it they just
stuck both antennas on a mast & shipped it?  Or did they have to do some
tweaks?

Has anyone tried to combine DB224E & DB408 on the same mast?  We have one
free space on a nice tower with a good location.  The 2 meter antenna on the
tower needs replacing.  I would like to install a 440 repeater.  I have both

Just went down and checked a few things.

Yes, CG is on transmitter. I pulled the cable to it and the TX went
off. It wouldn't key with the tone disconnected...is there a jumper
you have to use for no tone?

It's the intercom button on the 10volt card that causes the tx to go
off when you push it. 

I've noticed when the TX is off using this switch I hear a hum like
it's pulling more power. Maybe normal but doesn't make the sound when
tX is full power.

PPT light is on on the 10v board. Never goes off even after pulling CG.

This one hasn't had any mods. All original GE as far as I know.

Going up on the hill to play with the other one now...

Thanks for everything,
Ben

Steve, Jeff, Nate,

Ya'll are on the right track. I did some additional tests. It not the
147.765 subscriber it's the 147.93 subscriber that is throwing the stinky
stuff into the fan. Keying the 33 repeater does not cause the 165 repeater
to come up. However, when both repeaters are on the air 33 will keep 165
keyed & the 33 audio can be heard on the 165 repeater. As soon as the 33
subscriber unkeys the interfering signal on 165 goes away. 

I a ham not infected with ctcss phobia, therefore 33 (which I built) has RX
& TX tone. This lets me TX on 33's input & not key the repeater. The 165
repeater is not interfered with. Also lowering the power of the 147.930 TX
clears the problem. 174.33, 147.93 & 147.165 have to be on the air to cause
the problem in the 147.765 RX. I assume it is in the 147.765 RX, I don't
have access to look at RX audio on the 147.165 repeater.

Is it valid to add 600 kHz to the intermod calculator? I get an interesting
fifth order when I do.

147.9300 MHz - 147.3300 MHz - 147.1650 MHz - 0.6000 MHz - 0.6000 MHz =
147.7650 MHz Right on the 147.165 input.

As I said before, the owner may have added a preamp to 147.165 a day or two
ago. This problem just came to light last night. These two repeaters have
been on the air for years. I was wrong about the spacing, they are 4 miles
apart. The 33 repeater equipment was getting tired & I replaced it with a
Mastr II station repeater two weeks ago. I can't say for sure if the
problem started with new 33 equipment or the preamp on 165.

It looks to me like the cure is to notch 147.930 at the 147.756 receiver.
Anyone have any thoughts.

Yep, that's going to be the key... been there done that... Ye olde 600
KHz split on VHF problem.

It creates perfect mixes with users and the repeaters themselves that
fall right smack on the input of the next repeater along the band. A
close-in high-powered user to a VHF repeater can mix with it with bad
results for the next in line machine. Requiring CTCSS on a different
tone than the original machine and users will cover up the problem,
but not fix it, of course... not a permanent fix, but sometimes
necessary.

If Jeff's observation is correct, and you only hear input activity...
try to find a ham who's rig causes the issue consistently (and you'll
probably find that HT users don't, also -- they're usually just too
weak to create a strong-enough mix).

Then you can have that person lower their power and see if the problem
signal on the repeater's input seems to drop out quickly or get much
weaker, since you're looking for a mix that would drop off rapidly as
one of the transmitter's power levels was lowered.

If that's not it... have a 600 KHz AM station in your town? There's
always the possibility of other mixes as well... Jeff's test is the
kicker to start with -- do you hear the full TX tail of the other
repeater or just user input? Does it do it on ALL transmissions or
just certain users? Anyone involved in the situation live real close
to either repeater, who you know has high gain antennas and runs lots
of power?

I drive a truck OTR and at times work with FEMA. Would it be possible
to put together a mobile repeater system that could be used in areas
without power? I have a generator system in my truck so I have 110
power available. My interest would be in something semi permanently
installed without need for putting antennas up or down. I realize it
would have a rather limited reach but would theoretically allow an ht
user 5 miles east of the truck to talk to an ht user 5 miles west of
the truck when they wouldn't be able to talk simplex. With mobiles the
effective radius presumably would be greater as well.

My questions are is this feasible and reasonable? What would be the
least expensive system I could put together to do this job? Thanks in
advance for all suggestions. 73 Leo K5LDB

keyed & the 33 audio can be heard on the 165 repeater. As soon as the 33
subscriber unkeys the interfering signal on 165 goes away. 

I a ham not infected with ctcss phobia, therefore 33 (which I built) has RX
& TX tone. This lets me TX on 33's input & not key the repeater. The 165
repeater is not interfered with. Also lowering the power of the 147.930 TX
clears the problem. 174.33, 147.93 & 147.165 have to be on the air to cause
the problem in the 147.765 RX. I assume it is in the 147.765 RX, I don't
have access to look at RX audio on the 147.165 repeater.

Is it valid to add 600 kHz to the intermod calculator? I get an interesting
fifth order when I do.

147.9300 MHz - 147.3300 MHz - 147.1650 MHz - 0.6000 MHz - 0.6000 MHz =
147.7650 MHz Right on the 147.165 input.

As I said before, the owner may have added a preamp to 147.165 a day or two
ago. This problem just came to light last night. These two repeaters have
been on the air for years. I was wrong about the spacing, they are 4 miles
apart. The 33 repeater equipment was getting tired & I replaced it with a
Mastr II station repeater two weeks ago. I can't say for sure if the
problem started with new 33 equipment or the preamp on 165.

It looks to me like the cure is to notch 147.930 at the 147.756 receiver.
Anyone have any thoughts.

Yep, that's going to be the key... been there done that... Ye olde 600
KHz split on VHF problem.

It creates perfect mixes with users and the repeaters themselves that
fall right smack on the input of the next repeater along the band. A
close-in high-powered user to a VHF repeater can mix with it with bad
results for the next in line machine. Requiring CTCSS on a different
tone than the original machine and users will cover up the problem,
but not fix it, of course... not a permanent fix, but sometimes
necessary.

If Jeff's observation is correct, and you only hear input activity...
try to find a ham who's rig causes the issue consistently (and you'll
probably find that HT users don't, also -- they're usually just too
weak to create a strong-enough mix).

Then you can have that person lower their power and see if the problem
signal on the repeater's input seems to drop out quickly or get much
weaker, since you're looking for a mix that would drop off rapidly as
one of the transmitter's power levels was lowered.

If that's not it... have a 600 KHz AM station in your town? There's
always the possibility of other mixes as well... Jeff's test is the
kicker to start with -- do you hear the full TX tail of the other
repeater or just user input? Does it do it on ALL transmissions or
just certain users? Anyone involved in the situation live real close

of power?

Subject: [Repeater-Builder] Effects of doubling RF output on UHF repeater?

One of our 70cm Amateur Radio repeaters is currently outputting 50 
watts into the duplexer.  We're considering replacing the existing RF 
power amp with a 100 watt model.

Current draw on the 50 watt unit is 8 amps.  The 100 watt unit will 
draw 20 amps.  Our power supply is rated at 36 amps continuous, and 
the duplexer is rated at 250 watts.

Half of our users believe that the repeater's output power is 
perfectly matched to its receiver.  That is, users of high powered 
mobile radios generally lose repeater reception at about the same 
time the repeater's receiver loses them.

However, the other half of our users believe doubling the repeater's 
power output would generate increased activity since the repeater 
could be heard more "comfortably."

We could upgrade without changing any of our other infrastructure.  
However, these questions arise:  1) Will the hundreds we pay to 
upgrade actually translate into significantly increased range?  2) 
Will we risk generating additional receiver noise by doubling our 
output power, thus losing coverage in the process?  3) Will using a 
higher power level shorten the life of other system components over 
time (e.g., power supply)?

By the way, our frequency coordination would be valid even if we 
doubled our output power.

Given the horror story given here recently by Dave KA9FUR, I can't even 
consider ICM at this point.  It's as if most of the crystal manufacturers 
just don't care if they put out a decent product anymore.

Maybe the answer is DDS modules.  Sure, they need stabilization or 
compensation as well, but at least they become an integral, non-replaceable 
part of the radio.  Not sure how you'd direct FM them, though - they may 
not like having their reference modulated.

What about a band pass on 147.765?  It may take a crystal filter or just

Ya'll are on the right track.  I did some additional tests.  It not the

to come up.  However, when both repeaters are on the air 33 will keep 165

RE: [Repeater-Builder] Intermod

[Fred Flowers]

Kevin,

Please allow me to pick your brain.

 

I was just informed of an intermod problem with 2 two meter repeaters.  They
are on towers about 2 miles apart.  The frequencies are 147.33+ tone 107.2 &
147.165+ no tone.  Two weeks ago I replaced the 147.33 equipment with a
Mastr II station repeater & 4 cavity DB duplexer.  I believe the 147.165
repeater to be a Micor.  When the 165 is on the air, 33 can be heard on the
input of 165.  I show a third order of 270 kHz away & a fifth order of 270 &
105 kHz away.

My question is, are the 105 & 270 kHz signals close enough to cause problems
with a Micor receiver?  I have worked on Mastr II's sense they came out.  I
have spent the same amount of time running from Micor's. :-)  

BTW I heard through the grape vine that the owner of 165 added a preamp in
the last day or so.  I don't know what kind.  I don't know how he's dealing
with desense.

confused and reset or worse, lockup the controller. It also charges the
battery the RIGHT way, with a 3 stage charger. It can be duplicated I am
sure, but at the price, I just would buy it and spend the time tinkering
with the RF for a good repeater.

The 10V regulator seems to have a strange mechanical failure of some type. It appears to have intermittent operation when I apply pressure to it. (It is internitant on it's own, but pressing on the case seems to let me put it in either a on or off state.) Suspecting a cold solder joint, I reflowed the solder on the bottom of the board to make sure that the leads have a good connection, but it still is flakey. My questions are as follows.Are there any other components or connections I should be looking at in the radio?Could the bad connection be inside the case of the regulator?I just want to make sure that I get the problem fixed and sometimes the obvious failure, isn't.Thanks in advance for your guidance and advice.-- TerryKE4PJWYahoo!

and replace itwith the MASTRII exciter board. That'll fix that problem real fast. The onlything that you need to do is arrange for the necessary +10 Volts to operateit, even the least technical ham should be able to take care of that.

The only two that interchange I know of are the late 110 w VHF & 75/100 w UHF.  The early 110 w vhf that uses 4 transistors in the final and the low band may interchange.  I have both and I'll look.   Not only do you have to drill & tap all the holes.  You have to rob the little metal stand offs from someplace, to hold down the circuit board.  I've done it on a drill press but a Bridgeport would be easer & more precise.    Fred KF4QZN    - Original Message - From: Virden Clark Beckman Sent: Sunday, December 14, 2003 12:56 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Heat sink anyone?  Actually it doesn't, most of the heat sinks are band specific unless youwant to drill and tap about 20 some 6-32 and 14 4-40 holes in thealuminum to hold components down - I did it and it is a very tediousproject.-- 73...Clark Beckman N8PZDYour use of Yahoo!

Re: [Repeater-Builder] Re: mastrII help

[Fred Flowers]

Coy,   I use a different point to take audio from the receiver.  I use P904 pin 16 RX PA.  Look at the schematic for the IF & Audio board.  On the Audio IC U604 pin 6 one will see RX PA out.  This is used in the station intercom option.  C635 is used to couple the audio to the Audio PA.  You can remove that cap and not have to put a load on the speaker output.  If you want RX test audio put a switch in series with the cap.  Also notice that this point is after the volume control, Channel Guard filter & De-emphasis filter.  Use the NHRC vol-sq board to set your level to the controller.  One should have all one needs for RX audio.  Make sure your controller does NOT have de-emphasis enabled.   This method will give you control over the RX audio out & the radio will have the nice "GE" sound.  - Original Message - From: ac0y5 Sent: Saturday, December 13, 2003 2:26 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: mastrII help  Loren, I have a repeater built out of a VHF MASTRII mobile running a NHRC2 controller. First, your repeat audio should come from the Volume/squelch High next, if your repeat audio is not high enough crank up the Rx input gain. I suggest setting the master level out pot on the controller to mid point and then adjust the remainder if the controls to the desired level. I prefer to adjust the receive level for 4Khz deviation in, you get 4Khz out. That way if you ever need to make small adjustments you can use the master gain c
ontrol. as far as CAS or RUS I prefer CAS, but choose which ever you prefer. I modified the CAS detector so it would not draw excessive current from the circuit. Since I built my NHRC2 controller using sockets for all chips including the opto it was easy. CAS and RUS are active high (CAS/RUS output is about 9 volts unquenched) I used a resistor in the input pin on the opto tied to a NPN transistor Base. The emitter and collector are plugged into the emitter and collector socket pins of the opto socket. I used Molex connectors for all connections internally to the systems board and I found connectors for the Power input. I used no part of the cable harness. If you would like to try this, get a squelch/Volume board from NHRC.If you have tried what I suggested above, have you tried turning up the deviation level on the exciter board using the pot? Use a deviation measuring device to set your output.73 and good luck and let me know how it goes

Re: [Repeater-Builder] GE Z Matcher

[Fred Flowers]

Sean,   All you have to do is replace the PA boards.  Take the cast shield off the low pass filter.  That gives you better access.  Some people replace the medal strip between the PA & filter board with solder wick.  Put a small hump in it to allow for heat expansion.   Fred KF4QZN    - Original Message - From: Sean KE6MOW Sent: Saturday, December 13, 2003 10:08 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] GE Z Matcher  umm...

Re: [Repeater-Builder] UHF Links with Voters

[Fred Flowers]

I have a UHF repeater with two remote receivers.  The links are also UHF.  I use GE MVP's.  They operate as Mini repeaters with no drop out tail.  The path length is 20 miles and I run about 10 watts.  I use a 10 dB yagi on TX.  The receive ant is the same ant as the repeater  I use a mulit coupler to split off all the receivers.  I'm not using a voting tone.  If you are using a GE voter I think it can be operated without voting tone.  That way you don't have to run your link TX's on continuous. (If I'm not right about this, someone put me straight.)   Fred KF4QZN  - Original Message - From: franknmiss Sent: Wednesday, Decemb
