Subject: [Repeater-Builder] Wacom WP-639 Duplexer question

 

  

Good evening, our club has a Wacom WP-639 four can duplexer as part of
our repeater system. Input Fq is 147.915 and Output Fq is 147.315. We
have a 600kHz (+) offset. Very simply, our main problem is when we run
the transmitter at full power 100 watts, there is a HUGE desense on the
receive side of things. When we drop the transmitter power level to
around 20-50 watts, the receive side opens WAY up to a large area where
people can get into the repeater. As we begin to bring up the
transmitter power, "white noise" begins to appear and the receive side
starts to desense again. All the cables have been switched to double
sheilded cables and all the same wavelength in length. We have the
duplexer seperated & sheilded from the transmitter & preamp parts. We
have not replaced the antenna feed coax with double sheilded coax yet.
Antenna is a Hustler G7 atop a 55' mast. The duplexer was retuned just
over 1 year ago. Any suggestions as to what we could look into next?
Some of us believe the problem is with the tuning of the duplexer
receive cans. Thank you very much.

RE: [Repeater-Builder] Re: Seeking emergency system design help

[Andrew Seybold]

The new repeaters are exactly the same at the older ones, and the older ones 
are capable of being converted to narrowband with programming, all Motorola and 
the all are in simulcast mode, we have plotted the differences between one that 
is wide band and one that is narrowband in over 50 different locations and the 
signals are, when seen  by a mobile unit, weaker from the narrowband radios, 
the mobiles are all capable of both wide and narrow band service and of the 160 
channels in the radios some are narrow band, also at the same time we added 3 
new simplex channels on 150 and same result, car to car range is diminished 
somewhat however we have not measured that at the moment

Andy, my comment was not directed at the professionals, such as yourself and 
others I know personally that are on this list. They were based on his stated 
requirement for a disaster recovery radio system. It's not something to do 
cheap or without expert guidance.

 

People keep commenting on losing range with narrowband systems. A large UHF LTR 
system I installed and maintained lost no discernable range switching from 5 
KHZ to 2.5 KHz. All else was the same. Same antenna system, same repeaters, 
same mobiles. They just pushed a button to bring them to the new talkgroups.

1) There is NO requirement to go digital

2) There is NO requirement to go 6.25 KHz. Yet.

 

You can safely install an analog 12.5 KHz system and expect many years
of use from it. By the time 6.25 has a firm use by date, you'll be
looking to replace the current system anyway. Of course, you CAN use
something like MotoTRBO or NexEdge f you don't mind paying a bit more.

 

If this is truly an emergency type system, then you need professional
design help, not just from this list.

Please abandon the idea of using D-Star equipment modified for non
amateur use.
First this is ILLEGAL.
2nd there is no commercial equipment that I am aware of that is
compatible without modification.

I would suggest using Kenwood Nextedge technology.
This is very similar in performance to the D-Star and has a bandwidth of
6.25 KHz on a simplex radio (Mototurbo can not operate at 6.25 KHz
without infrastructure)
The FCC has already stated that the 6.25 KHz bandwidth is coming they
just don't give any date prediction and I would not design a NEW system
that did not comply directly with the ability to use this bandwidth.

This is probably the most stable technology in todays market that can be
set up with off the shelf equipment.
I am too far away to help but would be glad to advise any legal way that
I can.

RE: [Repeater-Builder] Re: unsubscribe (reading yahoo group posts - a butter way - no popcorn)

And I am one of those with separate folders for two reasons, first it
makes things easier to see, and I have never had a problem with getting
email mixed up, I subscribe to multiple yahoo groups and each one has
its own folder which makes it easy to see when there is new email from
each group.

Secondly and most important to me I get so much business related email
on my Blackberry that by using folders I don't get groups to my BB, and
so I can concentrate on business emails and when I check in with my
desktop or laptop I can see the groups with messages since the last time
I have looked at them.

In this case, then, a few spam messages are just easy to delete. I know
from experience that spammers don't have to have access to your email
account to spoof your email address, since mine has been spoofed
multiple time.

all of the agencies: Fire, both County and City, Sheriff, and City PD

The old GE Signal to noise voters work great-Doug Hall (Hall

CHP uses mostly 154.905 for their extenders (Pac-Rats), and they also
use it for chatter between cars-if you can hear a signal on that channel
there is at least one car close to you, when they leave the car and
activate their handheld  you will hear a beep on that channel also, many
CHP cars have started keeping their Pac-RT's turned off until they exit
the car-however many still keep them on all of the time.

This is off topic, but does anyone have a source for property and

As I recall I used to replace the voter lamps with 28Vdc lamps and they
were not as bright but lasted for a very long time, the 12V lamps run
hot-we used to replace all GE and Motorola Grain of wheat bulbs with 28V
versions to save on service calls for burnt out lights

Yeah they turned it into an innovation center-showing off future
technologies-I really enjoyed it-saw it first when working for them in
the late 1970's, and many times since, last time I was on campus they
held a cocktail party in it and had about 20 different new technologies
being shown and discussed, great look at the future but the past is just
as important.

Motorola had a really tremendous museum at their campus in Schaumburg,

It is now Against the Law in Il To Rebroadcast Public safety Communications

I know most of us in this Hobby are aware of all the Scanner Type

I always liked the idea of seeing something big on the News and finding a site 
from that area to listen to it Live . 

Well it looks like Il has put together a law against doing this I do not know 
about other states . Or how this is going to stop the On Line Scanner stations.

Also as written unless I have permission it looks like I cannot rebroadcast the 
Amber Alerts which come out over My Emerg Weather Receive on My Repeaters I "am

RE: [Repeater-Builder] Trbo to be DOA 2012 Say Hello to Tetra

[Andrew Seybold]

Well-there are several companies which are making 12.5 KHz conversion kits for 
Mastr II's and other radios, where are not type accepted for commercial service 
but can be used for ham service, the big issue to me is that the commercial 
community has years to prepare for 12.5 Hz narrow banding (below 512 MHz) and 
the vendors have been building systems capable of both wide band and narrow 
band use for many years. How long will it take to get these same vendors to 
start providing both 25 and 12.5 and then 6. 25 KHz radios for ham service? You 
cannot expect hams to simply dump their existing radios and buy new ones-public 
safety and LMR operators have had a lot of time to prepare so we should have 
the same option.

 

The bad news is that wide band commercial radios are going to be plentiful and 
cheap in the next few years as commercial operators are forced to change to 12. 
5 KHz channels, it would make more sense for us to be able to take advantage of 
these WB radios and stay wideband for a few more years than race to keep up the 
LMR folks.

The plan as I have it is to merge P25 and Trbo into a Tetra Product, for 
release in 2012, at which time Turbo will be discontinued and abandoned as its 
not true 6.25kc and wont comply with the new 2.5kc standard that all will have 
to start adhering to. Trbo takes up 12.5kc though it provides 2 voice paths, 
its not 6.25kc wide.

My question is when will the 440 and 2m bands start talking about making a 
unified 6.25 kc divisible bandplan and apply it nationwide? They will have to 
do it so might as well get started talking about it. I know that there are a 
lot of people with 25/30 kc radios that are not going to care for hearing about 
this. 

A good first step is to design the layout in 12.5 kc steps for each band and 
start planning on at least going to 2.5kc deviation around that time..

The attached will get you started with a repeater on port 1, and 3
remote bases on 2 3 and 4.

There are no id's included, although the contents have a line that
deletes them.

Follow them with a new ID on the next line.

It has a cactus style beep boop - but you can change it to anything you
want.

Hang times are there for the repeater, but zero for ports 2 3 and 4.

You can reverse engineer these commands and put in the parameters that
you want to change, and then load this back in as an ascii file to the
controller.

Each time you want to change something, change the attached .txt file,

RE: [Repeater-Builder] Just a Crazy Thought

CB Repeaters are illegal? You are assuming that the FCC is paying
attention to the CB band-last I talked to them they have walked away
from the band-no one is licensed, amps are used by lots of people and
the FCC does not have the people or the interest to patrol the
band-therefore it has become a no-man's land of 27 MHz garbage-the best
thing that could happen is that they start using repeaters and blow

There are devices which are used to provide home phone services via Cell
phone service-they create their own dial-tone and "look" just like a
landline phone but you will still need a contract or at least a prepaid
account, which I believe will cost you more than a simple Landline
phone-but If you want to investigate, try Cellular and there are others.

RE: [Repeater-Builder] Dropping the Autopatch--Keep 911

[Andrew Seybold]

I have an older Sprint Unit-designed to be used to replace house wired
service, it has an antenna, you plug it into 110vac and then it has an
RJ-11 on it which provides dial-tone and ringing to the rest of the
wired phones in the house-but it can also be used stand-alone. The one I
have has been activated but is no longer in service, I will part with it
for $50 plus shipping if someone wants it.

There are devices that provide an RJ-11 jack to interface POTS phones 
with cell phones. This would permit you to just plug your autopatch 
into the device. A web search will find these. They range from high 
end multi-line devices to those in the $100 to $200 price range.

This is a link that shows some of the lower end items. I am sure that 
there are more out there and there may be better ones than those shown

RE: [Repeater-Builder] Dropping the Autopatch--Keep 911

[Andrew Seybold]

Analog cellular was discontinued in Feb of 2009, AT&T and Verizon turned
their analog off on the day it was permitted-it is possible that some
smaller operators are still offering analog but I don't know of any-and
ALL cell phones are required by law to be able to dial 911 even if they
are not subscribed-the carriers and the public safety folks are trying
to get this changed because many people  are giving their old phones to
their 2-5 year older kids who are dialing 911 because they don't know
any better-but analog phones just don't plain don't work on either AT&T
or Verizon any more-Sprint and T-Mobile never offered analog so if there
are any smaller operators out there still offering analog then they
might work, but I doubt it.

RE: [Repeater-Builder] Re: Early FM Repeaters (tubes and more)

If I might add my 2 cents here-I have now narrow banded a number of
Mastr II receivers, all high band, using the kit from Com  Specs, it
works Great HOWEVER, the receivers all have a problem with the squelch
threshold and there is a lot of popping going on-setting the squelch
tighter does no good-the issue seems to be that the noise settings for
the Mastr II-we have tried many different fixes including adding a Mot.
Squelch, and adjusting the "hidden" magic pot-to no avail-even sitting
on the bench with no signal applied they are very noisy-and while the
sensitivity measures about the same as before, the performance is not.

A big can of worms and there seems to be a lot of people 
on many groups who live to post various FCC rules along 
with their interpretations. Bores me to tears to try and 
read the legalese these folks spout. 

Some key points if I may... 

The narrow band physical mod is to the receiver. The 
transmitter is not a mod, but typically a standard 
deviation and audio level adjustment. 

It is the responsibility of the License Holder to 
ensure the emissions are legal. I personally have been 
told by more than one FCC Field Agent and a former Office 
Chief... (still working at the FCC in a higher capacity) 
they are not going to get excited about properly upgraded 
equipment properly running within the limits of the 
license requirements. 

The above has proven to be the case the few times I've 
had site interactions with the FCC. I've never seen a 
Field Agent walking around with a type acceptance list 
or computer doing said look-ups.

now, other uses include full house control of lights, heating etc, each
light switch in a home is also a repeater and it will be used in many
new big office buildings where instead of running wires from lights to
switches the lights will be direct wired with a zigbee node and the

I worked on an antenna problem recently on a 900Mhz spread spectrum 
meter system here in Connecticut. I only spent an afternoon, but the 
technology is fascinating. Two way communications from selected sites 
to the meters will eventually be implemented. If the customers meter 
does not have a direct path to the site it can relay it's data through 
another meter that it has connectivity to. Kind of like a big mesh 
network. Every meter is also a repeater. It is eventually going to be 
a two way network, not just for meter reading. The power company will 
be able to control the load of devices in the customers home or business

location (presumably for a discounted rate) as the power company needs 
to adjust demand. A good example would be to shut off your electric hot 
water heater for 5 minutes. This would probably have no direct effect 
on the customer, but would be a great cost saver for the power company.

Using spread spectrum and 900Mhz, the range of this system is amazing. 
Very few meters are in dead zones. These bad zones only need a meter 
strategically placed on a high building or power pole to become a 
repeater. Very impressive system.

450-470 MHz is alive and well and still full of public safety, business
and other users (including, of course GMRS and Family radios), and it
won't be going away anytime soon-every new allocation made by the FCC in
the future is liable to be broadband only so the channelized stuff has
to have a home too-although the Public Safety folks also have 14 MHz of
"new" 700 MHz spectrum which is starting to be used for channelized
systems-all P25 and on 12.5 KHz channels moving to 6.25 KHz over time.

As far as the Securicor radio, I don't think it programs on ham bands,
and only later versions of the mobile had talk-around (simplex).  The
repeaters were set up for trunked use only.  They make attractive
ballast pieces for trebuchets and sailboats, though.

As a matter of fact, I'm playing with one right now.

If anyone has schematics or a service manual with schematics it would
be greatly appreciated and would aid my efforts tremendously. Or any
information on the mobile radio that was used with these would help as
the repeaters seem to share the RF and SPU boards minus a few
components here and there. It seems to be technology that has been
allowed to die.

The company that designed this stuff was called Linear Modulation
Technology out of England, a subsidiary of Intek Global. These were
later produced by EF Johnson as the Viking LX series. It is unknown if
Midland while under the Securicor name actually produced them or not.
Mine has a EF Johnson klingon added with the wrong shade of white
paint and a Securicor sticker slapped on top of that.

The system used is called Linear Modulation. Similar to SEA's ACSSB
system, but different enough that the two companies products are
incompatible. Apparently the FCC didn't care what people used on
220-222 MHz, as long as it fit into a single channel.

Both are Upper side band designed to fit in a 5kHz wide channel. DSPs
spilt the audio passband in the middle for insertion of a pilot tone
while the upper portion of the original audio is transposed above the
pilot tone, you get about 3300 Hz of audio bandwidth, about 400-500Hz
of split for the pilot and the rest is channel guard. In LM, the
pilot tone that is used for AFC and AGC. In ACSSB the pilot tone also
serves to send trunking data, while the audio is compressed and
expanded for noise reduction.

In the Securicor the receiver brings the RF down to a 12.5kHz second
IF and the DSP goes to work on it as a software defined radio. As a
matter of fact this is considered the first SDR made, with patents
back to 1991.

The transmitter is basicly a phase method SSB generator that uses the
DSP and 2 DACs to generate the 90 degree phase shift. there are like 5
mixers on the RF board.

RE: [Repeater-Builder] Re: what pac-rt means

[Andrew Seybold]

George-I will let the Motorola guys on here answer most of your
questions, I tend to stay on the GE side of things, however, the HT does
not become a repeater when placed in the cradle, but a simple HT turned
into a mobile, The HT's generally had a single channel in them, with PL,
not sure about that one, the switch I believe you will find was supposed
to enable and disable the PAC-RT that was attached to a different mobile
radio mounted in the trunk and with a control head up front, therefore
the combination you have should work as an HT and also as a mobile with
amp but not as a repeater.

 

Hope this helps a little

RE: [Repeater-Builder] what pac-rt means

[Andrew Seybold]

Just to be clear the "drop" is planned, it is designed so that when
multiple cars are on the same scene only one of them has a PAC-RT in
operation, otherwise it would be a zoo-so the drop is really the
synchronization of multiple PAC-RTs, the first system I was involved in
was in the mid-1970's and was the state of Ohio, then on to California
and the CHP, and Nevada used to use PAC-Rts. Also, today you can find a
lot of the mobile repeaters around-and they make good portable
repeaters-HOWEVER, most of them, at least the GE ones, made sure that
the receiver sensitivity was very poor so that it only picked up local
HT traffic. If you have one you will find that in the first receiver
stage-the ICOM and associated components, there are a number of caps
which have been left out in order to keep the receiver deaf.

I always found  their selection of radios to be a bit odd until about 10
years ago. For a while they would use the GE system in the car and a
motorola for other systems, but the two would never really synch
properly and there was always the drop out every few seconds that was
only about a half second long but none the less annoying! i think they
have changed systems now and odnt have this issue anymore.

Wesley, no I don't in fact my module is sitting at a shop of a friend
who has three others just like it, all with the same problems-the
biggest issues are below-but also the fact that many of the IC's are no
longer made and there are no substitutes for them-which is why I added
to your post, hoping someone in this group had a magic solution, I
really like the 3000, simple to operate and stays on Freq when it is
working-but I guess I might have to try and solder the ICs into the
board and see what happens.

Fortunately on the left coast we don’t really have a lightening problem AND 
since our sites are all within view of the ocean, I don’t do anything but 
fiberglass OR coated folding dipoles, aluminum does not like salt air at all.

 

And as Nate says—all you have to do is look around—and you will end up on a

the Northeast FM Repeater Assn, and then Phila’s Para, then on to Cincy, and 
the same thing, make friends, show you know a little, have a Cushman and are 
you ever popular.

Now on the left coast, this has happened twice—once near San Jose and now in 
Santa Barbara—LOTS of repeaters, very few folks who know how to make them talk 
and keep them talking—it is a lot of fun, and rewarding, and yes it costs money 
out of my own pocket here and there but that is what I like to do—build em and 
keep em running—let someone else use them!

realize something's wrong with the repeater...

 

But... after all the good comments about the Hustler Spirit antennas, if I 
*had* to use a fiberglass stick, it'd be first in line in the spreadsheet for 
cost/benefit analysis!  :-)

 

Otherwise, 99.9% of the time, it's Sinclair folded dipole arrays for me.  The 
heavy-duty ones, not the wimpy little ones.  (GRIN!)

 

And to the guy who just showed up saying he has "always wanted to build a

some help years ago, and now I have repeaters coming out my ears.  

 

No need to build your own... in most areas there's PLENTY of repeaters that 
aren't performing up to spec, and/or need some TLC.  Getting involved is step 
one, step two is shelling out real money for your own test gear, and once you 
have that... you're "sucked in" forever.  And not just for your machines, it's

RE: [Repeater-Builder] ARRL Approves Study Committee to Research & Develop Plan for Narrowband Channel Spacing

[Andrew Seybold]

The narrow band requirement for commercial LMR is for stations in the
150-512 MHz band, they have already been purchasing wide band/narrow
band capable radios for a number of years-the dates are Jan 1, 2011,
only narrow band radios can be sold, and Jan 1, 2013 all stations must
be using narrow band (12.5 KHz) but there is also a further order that
says narrow banding will continue to 6.25 KHz, and yes, going from 25
KHz channels to 12.5 KHz channels reduces the range of a repeater by
about 30%, and lots of public safety agencies have filed for waivers to
extend the time beyond 2012 but it is my opinion that the FCC will not
grant the waivers-

I have also narrow banded several GE Mastr II receivers-using the
filters sold by Comm Specs and I can tell you that this mod create havoc
with the receiver squelch noise levels, and basically makes the receiver
a noise generator-

As for getting additional spectrum in the 2M band-dream on-we are very
lucky that we are not losing what we have-and if you are in Northern
California you might have received notice from the feds that your 440
repeaters need to be tuned back to 10 watts of output power because of
the Increased Federal band usage.

Most 2M repeaters are underutilized and the FCC has been tasked by
congress with providing a list of all spectrum and its usage-when they
make their tests if we are not making use of our spectrum on a regular
basis we are going to lose more of it-so the end game here is to make
use of the spectrum we have and to increase traffic on the repeaters in
any given area-the idea of private repeaters with a few users may cost
us spectrum in the future-more open repeaters with more users will help
our cause-what is the expression? Use it or lose it-and this is a VERY
real threat to us, the commercial operators are looking for 800 MHz of
additional spectrum -and it won't take them very long to identify what
we have as spectrum to go after.

If so, I need a favor.

The first implementation of PL used about 20 tones.
The 32-tone "standard" list didn't come until later.

Does anybody have a copy of that early tone list?
It would have been somewhere in the 1950-1955 time frame.

Web Page GE LBI listing is pretty darn impressive. 

I found the 100 watt Low Band Transmitter Manual before Eric 
provided the PA PDF URL so now I have both. I saw in the 
transmitter manual the normal "nominal" drive is about 250mW. 
(thank you Eric)

I can't find the numbers listed below on the board with the 
exception of a large 6 etched out of copper on the board. I 
might now assume the unit is the 30-36 MHz unit mentioned 
below unless the pc board label is printed somewhere not within 
obvious view. 

If the PA is the 30-36 MHz range... I'm starting to wonder 
how well it will work at 29.6 for Amateur Radio 10 Meter 
Repeater work?

Again thank you for your replies... I'm still sorting through 
the remaining flea market "stuff".

RE: [Repeater-Builder] GE LB VHF RF Amplifier Drive Level? basic specs?

[Andrew Seybold]

Check out http://www.repeater-builder.com/ge/lbi-master-list.html  do a
control F and type in the part numbers

 

They sound like typical lower powered amps for base stations (as opposed
to continuous duty repeaters. They are designed to mount in a base
housing where any of the amps go, they should have one PL-259 on a
angled bracket and room for another one just above it, 

Hope this helps

On the way home from yesterdays Lincoln, CA. Ham Swap 
I noticed a bunch of surplus GE Radio Gear just "up and 
jumped into the back of the truck". 

Two of the hitch-hiking items were GE VHF RF Amplifiers, 
looking a lot like a GE Master II Mobile decks factory 
mounted into a frame used in a base/repeater application. 

The RF Decks appear to be VHF Low Band units with the 
printed part numbers of PL19B219688G6 REV on each. The 
final output devices are 4 labeled C4104P1 transistors 
as is the single driver. The remaining first input device 
is a transistor labeled C6965P1. 

So... can anyone tell me the basics about this PA Model? 

Drive Level? 
Realistic Output Level? 

The output of the PA goes toward a covered T/R Relay section 
in the chassis/frame corner where I see connections for a 
receiver port. Is the T/R Relay normally powered/energized 
with each transmission to route the RF Amplifier to the Antenna 
(output) Port? All the RF Connections appear to be the RCA 
type... 

Unlike Motorola RF Amplifiers... I'm not seeing an RF Power 
Stage Control Voltage line/wire/connection point from/on the

The two chassis that came home with me look to be real cookers

RE: [Repeater-Builder] Passive fer wifi

[Andrew Seybold]

Dennis-used to do it on VHF a lot, the Garden State parkway in NJ has
maintenance sites about a mile off the road-in order to cover them we
used back-to-back yagis or corner reflectors-HOWEVER what made them work
was the harness between the two-in those days done by Phelps-Dodge-VERY
critical dimensions.

 

Have never tried Wi-Fi, there are a lot of cheap active Wi-Fi repeaters
available which work well if you have AC, and IF you have enough signal
to feed them at the location you pick.

 

Otherwise a second access point at your house with an outdoor yagi
attached to it might do the trick-not a second Wi-Fi router but an
access point only with an external antenna-they are also easy to come
by.

What happens if you use the bandpass and the duplexor on the other 2M

My next attempt is to take the bandpass out of line and try it just

Good news John, I trust that the receive antenna is higher than the
transmit antenna? And it appears from what you said that the vertical
separation is sufficient to take care of the de-sense issue-HOWEVER,
that does not mean that your transmitter is clean, only that you have

We did discover that the receive works great when the transmitter is
attached to another antenna.

Receive strength went way up. But, of course that doesn't fix the

So for now, the receive will be on the repeater antenna and the transmit
on a separate 2 meter antenna.

What model of watt meter are you using? Typically the accuracy gets
worse 
at the low end of a particular range, so unless you're switching 
ranges/replacing slugs to keep the forward indication at the top 50% of
the 
meter's scale, the accuracy may degrade.

Could also be a TX that's going dirty at the higher power level.

If you aren't using an isolator between the TX & duplexer, I'd try that 
first. Sometimes the Mastr II RFPA doesn't "like" the pure reactance of 
the notch in the duplexer.

Hi Rodney and others.
The CAT5 cables are definitely shielded and I suspect that they are
properly terminated.
There are 10 CAT5 cables in total and an LMR200 cable. I suspect the
LMR200 goes to a GPS unit which is on the tower. Six of the CAT5's go to
the six panels and likely the other four are used on dishes on the tower
that pick up and relay the signals coming to the tower.

The VHF repeater is using a Sinclair 210-C4 on the top of the tower with
the panels mounted just below that (approx. 10 feet down) 
The repeater is multicoupled to the 210-C4. All feedlines for VHF and
UHF antennas is hardline.
The power supplies for the panels are switching type. The noise is
across the VHF band. 

Thanks for the comments so far.

[Repeater-Builder] Enabling PL encode on icom repeater

[Andrew]

Hi,
I have installed an external controller to an icom repeater as per the pdf on 
the RB website.
I see how to get the PL decode working again, but does anyone happen to know 
how to re- enable the PL encode after the internal controller has been taken 
out of the loop.

[Repeater-Builder] RE: UHF REPEATER ANTENNA IDEAS WANTED

[Dr. Stephen Andrew Wilson]

Dear Friends:

Our club (Radio Club Querétaro, XE1RCQ)is in the process of putting
together a UHF repeater for our authorized frequency of 438.150.  At
the moment we only have a Ringo-type antenna, and are looking for
ideas for more efficient home-made antennas for this purpose. I tried
several Google searches, and only came up with a few trillion
commercial UHF antennas.

Our system at the moment is quite simple, and consists of two Motorola
GM300 radios, with a Celwave duplexer. 

Thanks in advance for your kind assistance.

[Repeater-Builder] spectra repeater?

Re: [Repeater-Builder] Re: MSF 5000 CLB

[Andrew G.]

Bob,
   Sounds like there's a problem with your Arcom controller (RC-210 I guess?). 
I've had mine bug out a few times where something similiar would occur, but it 
usually corrected itself after being reset. Could be firmware or a bad 
programming string somewhere... 

As far as the open squelch noise goes, thats something I've never encountered. 
I run 3 CLB UHF Stations and a CXB 900MHz Station with no cooling on the 
control tray and this hasn't happened on any of them. Is the white noise 
appearing in the hangtime only with no cor activity on the RX? Does this still 
happen when you run the MSF with the internal controller?

Andy KC2GOW

P.S. We can fight over the legality of the time announcement on repeaters on 
another thread...hahaha

Hi,
Does anyone happen to know the current draw on transmit of a 100W UHF
Moto MSF5000. 
The VA rating on the sticker calculates out to around 8A. I just want
to be sure before I go plugging it in and tripping a circuit.

Re: [Repeater-Builder] GR300 Repeater Housing - Fan Replacement

Tony,
It's been a while since I've opened a GR300 case but I do remember it being 
nothing more than a standard 4" Fan in the back. Just about any should do the 
trick. You might want to re-mount your fan to the outside of the case for easy 
replacement/cleaning (thats what we did to avoid ripping everything apart).

Also, when you flip open the control tray, make sure the blue ribbon cable is

Subject: [Repeater-Builder] Help with dead msf 5000

I bought a msf 5000 cxb vhf station for my club to build a repeater. 
this unit was rack mounted along with several public safety repeaters 
so I did not get it in the original cabinet. I was shipped the power 
supply, the pa and the rf deck with controller. Before shipping the 
seller removed a secure board because hams do not usually need them and 
we dont. I reasembled the unit in a 4' GE cabinet and connected all 
the cables that were sent to me as best as i could figure out without 
any instructions. When i plug the station in the 12 vdc cooling fans 
come on but the control deck is dead. I found 1 cable that came from 
the power supply and plugged it into a jack on the rear of the rf deck 
and another cable that went to the pa from the rf deck. I also found 
and connected the rf cables as needed. There are still some left over 
connecter pins on the pc board at the rear of the rf deck that I do not 
know what is supposed to be connected to. Inside the control deck I 
see what looks like a 5 pin connector coming from the rf deck and it 
does contain 13.2 vdc on the red and black wires. Something must be 
missing causing the controler not to light up at all. Cam anyone 
supply me a interconnect diagram so I can see if i have a missing cable.

Yes, it does have three slots for horizontal modules. They are filled

So I would say it's a full duplex unit. When it was in service it was
used with Wireline control.

Eric,
 USE THE RADIALS. I tried using a couple that had lost them to the wind/ice 
also and the performance is pretty poor. I just made the radials out of some 
aluminum stock and bought a new hose clamp. RFS gave me the exact dimensions 
for the radials for 440-450. If I find them I'll post them. Otherwise if you 
call they should give them to you.

Hi Guys,

We've made tremendous progress on the 7330 since my last report! Here's
the latest news:

1. We've set an introductory price for a package consisting of the 7330
Main Board and LED Display Cabinet combination at $399(!) plus shipping
($15). This is an *extremely* competitive price for a controller of
this quality and capability.

(If you haven't yet read the paper that discusses the philosophy behind
this new series, please check out
http://www.scomcontrollers.com/downloads/scom7330newdirectionspaper.pdf.)

2. The cabinets are finished and the Main Boards are being assembled.
I've built some display boards, and wow, do those blue LEDs look cool
against the black front panel and white graphics! (Yes, Mike, the Power
ON LED is green.. :-)

3. We still have some work to do. For example, most of the testing is
being done by Dave and Steve in their individual dungeons and needs to
be moved to the LaPorte shop. Dave's working on the manual. And both
guys are continuing to work on items that appear on our long
"wouldn't-it-be-nice" feature list.

4. Rather than turn this thing loose in its current state, we'll be
looking for a few customers to become beta site testers. We need folks
with previous 7K programming experience who can bridge over to the new
command set with limited documentation. If you're interested, please
note that the price will still be the same and you'll need easy access
to your repeater site. On the other hand, you'll be contributing to an
interesting evolutionary period in controller history.

5. While no one on the design team will be at Dayton this year, a 7330

Re: [Repeater-Builder] New repeater Motorola or MA/COM

[Andrew G.]

My bad on that one Steve. Meant to only throw it in as 900. We had a need for a 
high split 900 station 934-950 and could not get a M3. Still fighting Motorola 
for a Quantar to use there. Due to the frequency pair we have, it overlaps the 
two models they make between
  TX freq & RX Freq, but thats another story for another thread.

  Hello Andy, are you meaning the M3 is not made for 800 Mhz., or not 
dual band (800/900)?  The ones I maintain are 800 Mhz.  Steve

Re: [Repeater-Builder] Moto GM300's Used With External Controller - COR Problem

[Andrew G.]

Make sure pin 8 on the 16pin accesory connector is programmed to be an output, 
with an active high signal output with COR. Once that is setup it should work 
like normal.

Re: [Repeater-Builder] Coax for cabinet and for feedline - other than hardline

  It is a wise move. I used about 75ft of LMR-400 to get my UHF machine on the 
air in a pinch. This install unfortunately became permanent. For a while the 
LMR is OK but after about a year or so in the weather you start getting duplex 
noise occasionaly in the machine. For a 130ft run Andrews LDF4-50A (1/2") or 
eqivalent is fine. If you want to spend the extra money LDF5-50A (7/8") is a 
lot thicker/stiffer but has about .8db of loss for 100ft @ 440MHz.

  The RG-142 is OK for duplexer cabling. Only improvement here would be to go 
to RG-214. As far as equipment jumpers RG-214 would be the better bet 
especially for the TX side of the duplexer.

  Bad Idea. The Daiwa is a nice meter, but is not exactly the best shielded 
device in the world. Especially with "UHF" SO-239 connectors on the back. Just 
adding more loss and another source of noise/desense in the cabinet.

  The Diamond is fine in my book (prefer with N connector but whatever is 
available). If you want to go commercial grade, the RFS PD-1151 is the 
equivalent to the 510. Otherwise if you want to really look for the horizon 
with the most gain, the Andrew or RFS 22ft 10dbd verticals are really nice.

  The 850 is better than a micor (not trying to start a holy war with this one 
guys) in the long run. It is new, synthesized, and best of all, new. Never had 
a problem with one before.

Does anybody have info on this radio? Specifically I am looking for where to 
get COR/PTT/AUDIO to use this as a link radio. Any help is appreciated.

Re: [Repeater-Builder] MSF-5000 external PA

[Andrew G.]

I don't know about an MSR2000 PA because of the design of that station. I would 
think that if you gave the MSF station itself the voltages it wants through the 
control cable and had an external PA to take the IPA power, it would work. 
   
  P.S. I'm also interested if anybody has done something like this.
