Gary:  The guy that marketed that 40 db power pad was actually a rep,  
a real character.  I still have the data sheet and picture somewhere  
here in my library.  He used to tell me his real money came from  
making and selling waders.

BTW I do have the schematic and JPEG of the Cushman 40 db pad with  
the fuse inside.  Should I send it to someone?

One brand I considered was Crescend for UHF, they are rock solid.

Okay all, looking for opinions.


Our club is going to purchase a 220 amplifier and a 440 amplifier  
for our repeaters.


For 220, we're looking at either the TE Systems 2210RAN or the  
Henry C100B10R

For UHF, it's either the TE Systems 4412RA or the Henry C100D30R.

We have a Henry C300C30R in use for about 3-1/2 years now (running  
it at 250w output) on our 6-meter repeater and had to send it in  
about 13 months into its life to have the finals replaced.  No  
problems since, though.  I was pleased with Henry's response to the  
problem.  Even though it was out of warranty, they fixed it under  
warranty.


Though the TE systems amplifiers have more output (150w vs 100w), I  
have concerns about their reliability.  The local D* repeater has  
had a lot of problems with their VHF amplifier, and it's not very  
clean (of course, that could be the fault of the D* repeater  
transmitter, too!).


What are your opinions, TE Systems vs Henry?

Re: [Repeater-Builder] Mastr II synthesizer

Hello Brian:

I have a GLB synthesizer with the complet original manual in working  
condition when I took it out of the car.  when I took it out of the  
car, it was wrapped with clear plastic, and tucked away.  Never  
thought about selling it, but maybe it is worth $30.00 (plus  
shipping).  If you have any questions, let me know, and I'll check  
the manual.  I'm the original owner, and built it from their kit.  It

Hello:

I  presently have a dual band 2 and 70 cm antenna on the rear trunk

Re: [Repeater-Builder] DB-224 drain holes

[Tony Faiola]

Hello Dave:

I have a DB-224 stored behind the garage.  It didn't have the weep hole 
in the bottom of the elements.  I have pictures of it somewhere in my 
files.  What happened was water built up in a few of the elements, froze 
and bent the element like an arch or archer's bow.  I thought my 
eyesight was going West on me looking at it at the 200 foot tower level.

The aforementioned antenna was eventually replaced with a new same 
model, and it did have the weep holes on the elements.

It's also interesting to note that I spent money to send it back to DB 
Products since they didn't believe me, then they did.  They sent it back 
to me without repairing or replacing it.

The least they could have done is thank me for the change in future 
product design or replace the bent elements!

This is not the first time commercial and amateur radio manufacturers 
have eagerly placed products in the marketplace without proper testing 
in the "Real World".

[Repeater-Builder] FS UHF & VHF Duplexers

[Tony Faiola]

For Sale - UHF & VHF Duplexers

I need the room, and all these duplexers were working and taken out of 
service and stored inside.  I have more specs, however these are fairly 
popular duplexers (with exception of the one not known manufacturer VHF 
unit).

DB Products DB-4072 Base Station UHF Duplexer 6 cavity 2.75 MHz 
separation or more.

TxRx  five cavity Band/reject VHF 6.625" Duplexer.  Requires some 
interconnecting cables.

VHF six 8" cavity Pass/reject duplexer manufacturer unknown, but has

Asking $625 for all three as a package.

If you need more information or JPEG of each of them, let me know.  This 
is a first advertisement, and I won't go to other sell sites for a

Hello Skip:

Please give me your name and address, and I'll send you the three ring 
binder for the generator.  It will give you a good run down on the 
operation and installation.  Drawings are included.

You don't need to give me the six lottery numbers.

Re: [Repeater-Builder] Quintron Low VHF 4-400A PA

[Tony Faiola]

Hello Keith:

Take your time copying it.  I think there was another fellow interesting 
in the info also.  It cost me $12.00 to UPS it to you.  It's amazing how 
these shipping costs have gone up!

You need to share it with other interested hams, however I need it back. 
  There aren't many of these manuals out there.

The earlier ham just made me crazy getting it back to me.  It took him 
at least three months.  Others on the reflector had similar problems 
with others.  It's the small percentage that spoils it for others.

Anyway, glad you now have it to copy and share.

Re: [Repeater-Builder] Vega Tone remote model C-514B

[Tony Faiola]

Hello Jack:

Probably wasn't available because it was an early 90s product.  The 
C-514B control side is used with the RP-223B-4 remote station panel, two 
separate pieces, and the four frequency version of the C-510C. I assume 
you have both and require both manuals.

I have the manuals, however someone out there may get to you earlier 
than I.  However, if any source falls through, let me know, and I'll 
help you.

Hello Kent:

I'm not sure if you received any definitive answers concerning your query.

Many of the Motorola and GE base stations used tone or DC remote radio 
control consoles.  In some cases, the supplied stations already were 
equipped with the remote tone panel, and in others, they were purchased 
as a complete remote system.  Sometimes, DC telco leased line were 
utilized and sometimes audio telco lines, whatever was available at the 
time.

These remotes could handle one PTT or more (typically 2175 Hz) and 
multiple frequencies (F1-1950 Hz, F2-1850 Hz, etc), and Monitor (2050 
Hz).  Vega Signaling Products, Telex Communications, Inc. manufactured 
these products, and there are a number of others.

Without going on with more details, go to this website 
 and check out the many varieties of 
products mainly for signaling.  They had, and maybe still do, a fax back 
feature to download their manuals.  It was loaded with neat circuits of 
their signaling products, and could give you lots of ideas and information.

Some of the other radio manufacturers had some special requirements for 
their remote signaling (don't they all?), but we accomodated almost all 
of them.

Have fun.

David: Here's a draft of the test for some future column concerning the 
matter you asked about this morning at the Laurel ARC VEC test session.

Q. When a repeater transmits its station identification as [call 
sign]/R, isnt that in violation of Section 97.119(c) where it says that 
no self-assigned indicator may conflict with any other indicator 
specified by the FCC Rules or with any prefix assigned to another country?

A. Yes, it is. You are correct.

W3BE-O-GRAM: Embarrassing to report, but this question came during a 
Technician training class from a not-quite-ready-to-be-a-ham.

After I had explained that, in the station identification announcement, 
the call sign must be given exactly as assigned on the ULS (Section 
97.119(a)), but that Section 97.119(c) authorized one or more indicators 
to be included with the call sign. Each such indicator must be separated 
from the call sign by the slant mark (/) or by any suitable word that 
denotes the slant mark. If an indicator is self-assigned, it must be 
included before, after, or both before and after, the call sign. No 
self-assigned indicator may conflict with any other indicator specified 
by the FCC Rules or with any prefix assigned to another country.

For an example, I displayed the call sign of a local repeater appended 
with /R explaining that it is there in order to alert the users that 
it was being operated under the accommodations for repeaters in Section 
97.205

Assuming that so many repeater station licensees could not possibly be 
wrong, I told him that R was not a prefix assigned to another country. 
Wrong!

On the way home, it came to me that I had in the past worked stations 
whose call sign had the letter R as the prefix. A visit to 
http://www.ac6v.com/prefixes.htm confirmed that was still the case. Whoops!

Nice site.  What was very interesting was the chair behind the Collins

Re: [Repeater-Builder] Folded Dipoles for 6m Repeaters; Stacking for Gain?

[Tony Faiola]

Hello Robin:

We have modified some used Decibel Products low band dipoles of 
different sizes and fabricated a phasing harness to provide us with an 
approximate 3 db gain omni directional 6 meter antenna.

These three modified dipoles are on each side face of a three leg self 
supporting 200 foot tower.

We are still in the testing stage of this system, however you can check 
our web site to see pictures of it.   The 
site is new, so we are still in the process of updating it.  We will 
eventually include the design parameters for the three face three dipole 
type 6 meter antenna.

Re: [Repeater-Builder] UHF Power Amplifier

[Tony Faiola]

Hello Guys:

You're right on the money.  Initially, Vocom's  (Cresend) first attempt 
with amplifiers was terrible, lots of years back.  Any radio tech could 
have done a better job of putting something together.  I do have 
pictures of these first attempt VHF amplifiers to show others at the 
time to prove how lousy the product was designed.

For the past five or ten years, we have used the newer VOCOM 2 meter 
amplifier.  This is before they became Cresend, and I must say that this 
250 watt amplifier has performed admirably for this length of time.

They have their act together, and I would now recommend them for amateur 
radio repeater use.

Hello All:

Need to get rid of some things around here not being utilized.  One of
them is the subject Clegg FM-76 Transceiver, 220 MHz band.  A manual
copy comes with it, and there is no mike.  This unit does put out the
specified power and the receiver operates fine.  Loaded with crystals.

I'm not sure of all these crystal frequencies since it was difficult to
read them all.  Asking $80.00.  You pay shipping.

Hello Joe:

We just put up (before the cold weather) a phased three dipole (AKA 
DB-212-3) phased antenna array for six meters.  Each dipole is mounted 
on each face of our three leg 200 foot self supporting lattice tower. 
The phasing harness and feed lines are in the process of going up when 
the weather moderates.  There is design data available for the phasing 
harness, three and four dipoles.

We are looking forward to firing up the system in the Washington, DC 
area.  I do have a few JPEGs of it. I hope it plays as well as it looks!

Re: [Repeater-Builder] Looking for data on old heliax

[Tony Faiola]

Hello Jeff:

I thought I had an old comprod catalog, but can't find it.  However, I 
did have an old 1974 vintage Prodelin catalog.  It had their line of 
Spir 0 foam coaxial cable listed.

It did have listed in it a very similar 1/2" type cable with a VF of 
81%.  Perhaps they made this cable for com products or vice versa.  The 
VF for the 75 and 50 ohm cable of this size and 3/8" and 7/8" were also 
the same.

Again, if you want me to fax the page out of this catalog, let me know.

I'll bet the VF is 81% on that vintage cable.  During that era, they all 
competed with the same spec cable.

Hello Jeff:

I found a 1974 Phelps Dodge catalog in my library.  It covers the 50 Ohm 
Aluminum Sheathed foamflex cables, FX12-50 and FX 12-50H, but nothing on 
the FX-14-50.

Interesting thing is that the specs don't mention the VF, only 
dimensions, loss, etc.

If you would like, send me your fax number, and I'll fax you the pages 
of the cables from the catalog.

Re: [Repeater-Builder] message recording/playback on repeaters

[Tony Faiola]

The DRC 186 controller does this function plus many more, however the 
company that produced this controller no longer exists.

There are probably other controllers that have the function you seek.

Hello Walter:

We are presently working on a 6 Meter antenna system for our new 6 Meter 
repeater.

After looking at the various options, we decided to use some old surplus 
DB-212 Decibel products Side mount antennas.  You can use these side 
mounted folded dipoles in a single, double, triple, and quad type 
configuration.  We picked up some old beat up units and are using three 
of them on a three leg self supporting tower.  You can easily build the 
phasing harness for the more than one type configuration.

Check the specifications and application sheets on this antenna, 
available on a number of web sites.

If you chosse the three antenna option as we did, you will get gain and 
a fairly good omni pattern.  We thought this arrangement would be easier 
than  trying to mount a large vertical off the tower.

Ciao, Tony, K3WX

It has been a while, and no one has answered your request for 
information concerning the Quintron Corporation QT-7080 50 MHz Transmitter.

I gave (free) one of these transmitters away a number of years ago.  It 
was extremely well built and great for amateur use in the six meter 
band.  Fortunately for you, I never gave away the manual with all the 
schematics, etc.

Let me know if you still require the info, and I'll copy and send it to you.

Probably off list is better to contact me.

Re: [Repeater-Builder] M57719N RF power module

[Tony Faiola]

Hello Brent:

I have been working with some of these bricks from Toshiba and 
Mitsubishi.  If you ordered the module or are ordering this module from 
RF Products, buy the specifications sheet ($1.50) with the module.

The specification sheet has much valuable data in it including a power 
input verses power output curve, etc.

It's usually easier to lower an input stage than the power module (drive 
level) using lower voltage or low power pad techniques.

Looking at the aforementioned spec sheet curves, they show you what 
power output you can expect verses power input.

You do need to be careful of the power module output spectral quality 
with these procedures.

Hope these few tips help.

Re: [Repeater-Builder] Desense im guessing?

[Tony Faiola]

Most of the amplifiers such as the ARR (Advanced Receiver Research) are 
over kill on the amplifier gain i.e. 24 db, however the Motorola RF 
preamplifier, Models TLD8421B and TLD8422B have only a 10 db gain.  The 
latter has a two stage aperture coupled helical resonator and a tuned 
output stage to match the receiver input.  This little guy has very good 
spurious and image rejection, selectivity, and intermodulation 
characteristics.  We use it at our shared (two club receivers) sites 
with a four port splitter.  Net output is 2 db.  We use the ARR with a 
window filter to feed the two port and two four port splitters with gain 
left over.  This extra gain is padded down to prevent any of the radios 
at the output from being overloaded, and we have lots of different 
receivers at the splitter outputs.

The pad suggested in other posts after the preamplifier makes a lot of 
sense (not desense).

this is the 2175 decoder card.  BTW this 221 series was available in

You need the Model 510N tone remote control console (like a teleset with

Re: [Repeater-Builder] Re: Cetec Vega question

[Tony Faiola]

Hello Skipp:

The 221 and 222 Series was replaced by the 223 series about 12/87.  This 
new series replaced most of the new Motorola base stations tone remotes, 
also GE type base stations.

Please give me the model of your tone remote, maybe a RC-223, RC-223-2, 
etc.  I will send you a manual to loan you for copying and posting for 
others.  Anything you want to give me for postage or what ever, give to 
this repeater web site as a donation - sound fair?

I also have a Uniden ARU 251 450-470 25 Watt repeater manual available 
for someone to keep (not loan) and post for others.  I would hate to 
toss it in the trash when someone out there could use it.

O.K. Rod.  A good night sleep after drinking all those vodka martinis 
does help.

The Model 221 is the tone remote stations panels, including case and all 
mounting hardware Transmit (PTT) function only.  compatible with C-510B 
and Motorola/GE sequenctial tone format.  The price as of 1987 was $376.00.

Hello Rod:

It might be from the Model RA-231 DC-Remote Station Adapter (065-), 
but I'm not sure.

If you could send me a JPG of the board (component side), I could match 
it up with one of the many Cetec Vega manuals in my library.  There is 
just about every manual (pre 90s) in there.

Then I could make a manual copy to send you.

Hello Andrew:

Nextel used quite a bit of the Commscope 1 5/8" hardline at many of
their sites.  You may want to check some of the Nextel Techs and see if
they will loan you (I doubt it no one should loan tools) or put them on
for you at a reasonable price.

Ciao, 73, Tony, K3WX

P.S. I have step by step pictures (taken by me) somewhere in my file
(somewhere) of the connector installation at one of my Nextel sites.

[Repeater-Builder] Celwave PD200 Repair

[Tony Faiola]

In addition to my last posting, I forgot to mention one point concerning
the base sandwich.  Besides the metal plates having the three holes for
the clamping 1/4 inch bolts and the UHF female connector, it has an
additional open hole straight through the sandwich.  This is the weep
hole to leak out any moisture that would collect in the base aluminum tube.

The way this antenna is designed, we know that we would never use it
upside down for the obvious reason mentioned above.

Re: [Repeater-Builder] Celwave PD200 Repair

[Tony Faiola]

Attention:  Mike, WA6ILQ, Gary, K2UQ, and Randy, W0AVV

Hello All:

We finally took the 220 antenna apart, and it was an education. I would
like to share our experiences with you.

First, depending on the vintage of the antenna production, these
antennas may be assembled and disassembled differently.  I have looked
at some other Stationmaster type antennas, and there are some
construction variations, however my pictures and comments only concern
this particular model.

This antenna as I previously mentioned had been up on a tower for a
considerable time, and it was broken (and repaired poorly) about a foot
and a half from the top earlier in its' life.  This repair job probably
resulted in the eventual failure and extreme difficulty taking it apart
for trouble shooting and repair.

Mike, if I could Email the Jpeg pictures to you and make them available
elsewhere, then others can easily see the construction and problems that
can occur with this type antenna.

In the photo of the antenna tip, there is one allen screw holding the
last antenna element in place.  This allen screw goes through the brass
tip which is epoxyed to the fiberglass tube and pinches against the top
element.  This allen screw has to come out in order for the whole
element assembly to come out FROM THE BOTTOM of the aluminum antenna
base.  There was no heat necessary.

There are three countersunk screws at the top of the aluminum tube base
where the fiberglass tube meets the aluminum tube.  They need to come
out.  These screws hold the circular brass doughnut connected to the
internal brass tube part of the internal antenna.  Please note that
epoxy covers these screws, so you need to scrape the epoxy away very
well to get at the allen head, and be careful not to strip the head with
the allen wrench! Using WD-40 around each of the three screw rims
carefully helped in removing them. Also, the fiberglass is never
separated from the aluminum base tube.

Next is a killer.  This is the doughnut sandwich where the SO-239 UHF
connector is mounted.  The way this connector assembly is held in place
is by tightening the three 1/4 inch bolts and compressing the two
circular (inside the aluminum base tube) plates together with a rubber
bushing or doughnut inside.  This rubber bushing expends, and prevents
the the inside guts or antenna stacking assembly from sliding out.

What made it so difficult sliding this assembly out of the tube bottom
was the two plates were rusted and corroded very badly.  One of the
three bolts broke because the inside end was frozen.  We sprayed WD-40
around the inside perimeter so it would slide out easily, but it fought
us all the way.  We had to make up a plate with holes to place at the
antenna base tube, and use the two remaining bolts holes to mechanically
screw out the assembly.

The pictures show the center conductor break in the bottom element.  The
center conductor of this element needs to be replaced. Also, the two
sandwich plates are extremely corroded and need to be replaced.  One of
the pictures displays the foam spacers used to hold the elements in
place throughout the fiberglass tube.  We also noted there was no bees
wax in the tube, only the foam spacers.  

We have investigated the Polane T Plus epoxy for the fiberglas repair,
and the index needs to be updated.  The prices are out of sight as well
as the minimum quantity.  There are other solutions, but this is a
separate story.

I assume there are lots of these antennas out in the field, and they
could be modified and/or repaired for amateur radio repeater use.  This
above information might help you make a decision to buy a new one or
modify or fix a free bee.

Have fun.  Ciao, Tony, K3WX

I have removed these three allen head screws, however the epoxy is
wedged between the aluminum and the fiberglass.  Will heating the
aluminum near the fiberglass loosen the physical connection?

I did remove the allen head screw from the top metal tip.  With a little
WD-40 on the tip (no heat necessary) the one foot of broken fiberglass
pulled out of the tip and exposed the one foot of copper element.  It is
important to note that the metal tip separates into two pieces.  After
the allen screw is taken out, the center of the tip separates from the
collar portion of the tip.  This collar portion of the tip is fastened
by epoxy to the fiberglass tube at the antenna top.

I can see where we have to lay it flat on the ground or a board.  It
looks very fragile.

We did take out the three bolts as mentioned, but I would assume this
whole assembly should slide out of the bottom...or the top of the
aluminum tube?

One question is the antenna base.  There are three brass bolts, 7/16ths,
in the base around the UHF connector.  We took these screws out, however
nothing came loose.

I realize what you are saying about the top of the aluminum base support
tube, and it has to be separated from the larger diameter fiberglass
tube...but what about the connector portion of the antenna coming out. 
Does it slide out with the towards the antenna top or come out of the
bottom of the base aluminum tube.

Incidentally, for this PD-200 antenna for 220, the top element has the
bandwidth inscribed on the copper with the two operating frequencies.

Thanks for your first response.  I did take digital pictures of the
various sections and parts, but the big picture will come after
separation of the base parts.

[Repeater-Builder] Celwave PD200 Repair

[Tony Faiola]

Subject:  Antenna Repair Fiberglass Collinear Antenna

We were given a 5.8 db Gain Stationmaster for the 220 band, and it seems
to be very sick.

There is no DC continuity directly across the UHF connector, and the
VSWR is horrible!  

We are in the process of taking this antenna apart, however there are
some of you on this site have been there and done that.  This subject
has been covered a while back, but I can't seem to find any reference in
the index.  If I recall, there are three screws holding the base, but
the antenna fiber glass sheath will not pull out, only if a torch heats
the solder at the antenna tip.  

Also, the index does cover the Celwave Paint procedures for the
fiberglass after assembly (this antenna needs this work).  The index
needs to be updated, and even then the price of the gallon minimum of
the urethane paint and catalyst is exorbitant! I have been told by some
of the locals that a supply house in my area for Corvette and boat
fiberglass repair will fix me up with UV non metallic type urethane
paint at a reasonable price.

You can contact me direct ([EMAIL PROTECTED]) or via the builder site.

Thanks.

Tony, K3WX

John:

We had a very similar problem in the Washington, D.C. area with our
147.00/146.40 repeater, however it was a 160 Meter dipole off the 200
foot self supporting tower about 30 to 40 feet from the duplexed
repeater antenna.

We raised and lowered the dipole for experimentation purposes while all
were listening to duplicate the problem.  All listening appreciated the
education from it. You could hear the stronger of the two AM stations
come and go as we raised and lowered the dipole.

We went to remote receive sites instead of a duplexed repeater and never
looked back!

[Repeater-Builder] Micor Receiver Identification

[Tony Faiola]

Hello Everyone:

I have two Micor Receiver boards, and would like to get a schematic for
each one.  Also, what was their application?  There is nothing in any of
my micor manuals.

Board #1:  TLD 5782AV  Appears to be 142-150 range.  Has normal F1-F4,
but looks like it has 4 Rx and 4 Tx elements for F5 - F8.

Board #2:  TLB 8454B1 has two RCA type jacks on the board instead of the
normal one RCA jack.  Much more circuitry on the element side of this board.

Thanks for any information.

Tony, K3WX

In addition, the part number for this Motorola chip is 5183977M16, and
the list price is $19.61 (Ouch) each.  Therefore, be careful when you
try to salvage one of these chips from the A & S board.

Motorola has approximately 1500 chips in stock.

I have an Oregon Scientific wireless weather station, also on 433 mhz,
at the
50' level on my tower and I have never heard a peep out of it!  I have a VHF
weak signal station and operating on 432mhz have never heard it.  Our local
repeater uses 433mhz links and so far it has not heard it either, it is only
couple miles down the road from me, and with the weather station
transmitter at
the 50' level on my tower it would hear it if there was something there.
 I hear
mine at 433.95 and that's the only place I hear them.

I saw one guy told you about spurs all over the UHF band, that certainly
has not
been my experience here.

Try it, if it does put out all that crap, send it back!
