I know that they are available on the Batlabs site...  try

believe that the pinouts for the Maxar, Maxar 80, and Moxy were all the same.

All of the MSR2000 audio and control modules are the same, regardless of 
band.  Only the RF modules differ.

Where would I look to find a CTCSS Tone Board for an ex RCMP VHF repeater

Are the UHF CTCSS boards compatible ?

I also use Hijack This! and Startup Control Panel...  both excellent tools, 
but many less-experienced computer users won't know what to do with the scan

therefore only recommend them to those who know what they are doing under

Re: [Repeater-Builder] Silver Plating - Cheap & Easy

[George Henry]

It's actually used photographic FIXER that contains a lot of "free silver"...  
the fixer removes any unexposed silver in the film emulsion.  For many years I 
recovered the silver from my fixer by adding powdered zinc, which will dissolve 
more easily in the solution than silver will, causing the silver to precipitate 
out.  Collected over 28 ounces over the years.

His method of silver plating probably involved connecting the negative lead of 
a 
low-voltage source to the "can", filling it with used fixer, and then 
suspending 
a zinc electrode in the solution, connected to the positive lead.  The zinc 
goes 
into solution, and the silver, instead of precipitating out, plates out onto 
the 
can.  If the fixer is sufficiently loaded with silver ("exhausted", in 
photo-speak), it will plate out on copper without any current source, but 
adding 
the batteries will speed things up & result in a thicker layer of silver.

Re: [Repeater-Builder] More on GMRS - Fwd: FCC NPRM proposes complete part 95 rewrite

[George Henry]

The comment period for the NPRM ends July 7.

If you have not already filed comments in opposition to this radical 
re-write of Part 95, which would essentially turn the GMRS into more 
channels for FRS & possibly open those frequencies up to businesses, PLEASE 
do so immediately!!!

The most effective comments are those written in your own language, and 
citing your experiences with GMRS that make these rule changes unacceptable, 
i.e., the limits of simplex operation & therefore, the need to retain 
repeaters in GMRS, particularly for public service/emergency use; the 
behavior of children & young teens on FRS and unlicensed GMRS use that makes 
the elimination of the age requirement untenable; the need for licensing to 
keep voluntary coordination & interference resolution possible, as well as 
to retain the professionalism that currently exists among licensed users, 
etc.

Even if you're NOT a GMRS licensee, PLEASE help us defeat this!!!

[Repeater-Builder] Re: is a repeater needed

[George C]

The project can be fun, and educational...but are you talking amateur or GMRS? 

If amateur, look here:
http://www.txvhffm.org/repeater/

Set location to Houston and the hit "search". But look at surrounding towns as 
well. 

As far as coordination goes, there is a waiting list on 2 meters, not on other 
bands. 
http://www.txvhffm.com/index.php?option=com_content&task=view&id=113&Itemid=38

Look at "zone 2", which includes Houston. 

If you're talking GMRS, its tough. No coordinating body, but a good web site 
for info, and to see what's out there is http://www.mygmrs.com/

Try this again, my first posting never got posted.

I did a MSG search on Micor and got no where. I want to the FILES area and

Or what did I do wrong in my searching of this group?

Re: [Repeater-Builder] Re: Verizon Tarif

[George Henry]

Some people have successfully fought their local phone company, using the 
argument that amateur radio is specifically NOT a business (citing Part 97), 
and gotten residential or other cheaper rates than the business line rate.  
OTOH, some phone companies have refused to accomodate hams, stating that the 
tower location is obviously not a residence.  

Try contacting your nearest ARRL volunteer counsel...  he might try writing a 
carefully drafted letter on your behalf.  Letters from lawyers often get better 
results than letters from Joe Ham...

[George]

sir i agree...if you have infra red heater at front of you 2kw and the power is 
heating your ass after 6 hours of working outside at temperature below 20 
degrees F you will be apreciative for the comfort this thing provides and you 
will not be asking yourself how hapmful this microwave emitter isthis is 
the reality: stay away from antennas that emmit 1000 watts...mine is less than 
500 watts and no body is lurking arround.

[Repeater-Builder] Re: how far

[George]

thank you for the understanding! no offence of any kind here takeing or giving!
transistors are bipolar and made by mother motorola 8o watts capable each 
8X80=640 watts pure power PEP ofcource the lifespan will be short if the supply 
is 27 volts and the consimption is 80-90 ampers that is impossible to me...so 
the driving input is 130-140 watts the supply is 24 volts and the consumption 
is less than 60 ampers...purring like a kitten. the result is satisfying and 
the duplexer is happy with the power inputed to it.

[Repeater-Builder] Re: how far

[George]

the amplifier is class "AB" and is 8 mosfet transistors beautifuly engeneered 
to split and combine the power inside the amp...there are impedance balancing 
ciquits to keep the power properly distributed from the input amplfied and 
outputted to the duplexer or site combiner. now this amp runs far bellow it's 
capabilities just for the sake of the distortions that can occure from 
amplfying...moreover there is error ellimminating computer for the input signal 
just for the sake of linearity and error and distortion free output from this 
beast! yo know that this is important for digital communication
i am using it at it's power capabilities because is analog and does not matter 
the errors if the carrier that is carring my vice and the TPL.

[Repeater-Builder] Re: how far

[George]

i'll give you the answer:
i don't have commertial tower, that is why the high power at the antenna, that 
is why the high gain from the antenna for receiving, that is why the line is 
7/8 heliax foam 30 feet long, that is why a siclair antenna amplifier between 
the duplexer and the msf5000, now, my car has a 45watt remote installed 
spectra, modified to use 150 watt "C" class amplifier and receiving antenna 
separated from the transmitting antenna, that is why i am using 4 watt MTS2000 
all over the city and that is why i ask questions here "how far" and am i in 
the ball park with the range of my setup

[Repeater-Builder] Re: how far

well this amplifier is rated 90 watts you can see it on e-bay just type 
powerwave in the search. it has error eliminating computer inside and no 
distortion what so ever. i have it "modified" and use it at 450 watts and i 
pushed it with two power supplys that can put more than 120 ampers at 24 volts. 
the antenna is rated at 500 watts...
i wonder why woud they do that...just to put out 5 watts?

[Repeater-Builder] Re: how far

[George]

this is wrong: the amplifier that i use is linear rated at 90 watts running 
digital multicarier...there are arround 20 amplifiers inside the site. pointing 
120 degrees in a triangular pattern with 9 or more antennas like mine are 
emitting arround 2kw on one level only. the towers are two or three levels for 
different freqzs...there is big diesel generator in the site's yard that 
supplys the site in case of power outage.

ok the antenna is from cell site 14dbm 4-element in a plastic housing, the 
amplifier is 600 watts capable linear mosfet 8element hybrid splitters and 
combiners... but the power supply is up to 65 ampers at 24 volts, driven by a 
"C" class 130 watt amplifier. the antenna is not on a commercial tower (no luck

repeater is in the attic and the line is 30feet. the duplexer is celwave 
doesn't like more than 450 watts in.

The same channel elements are used in both the VHF and UHF MSR2000.  I have 
a number of the KXN1086 & 1088 elements (5ppm), currently crystaled for 
450 - 470 MHz.  I have had very good luck re-crystalling them myself for ham

Re: [Repeater-Builder] Cold temps and repeaters

I remember the 146.79 repeater in Henrietta (Rochester) NY back in the 
mid/late 70's  It was housed in an old 'fridge in a shed in the middle 
of a farm field, at the base of the tower.  IIRC, it had a fan to cool it in 
the summer, and a 25-watt light buld to keep it warm in the winter.

KISS at it's best.

I've seen it happen. Changes in temperature can affect the stability of a

weather changes as well. It's 12 chilly degrees here in western New York and 
the snow has been heavy all day. 45 would be a heat wave ;-)

The old command was: (PW) 18 (hours 00-23, minutes 00-59, month 01-12, day

The history of the "right coast" FM development is pretty accurately 
described on page 59 of this document:

http://www.docstoc.com/docs/11595271/The-History-of-Ham-Radio

I haven't quoted it for copyright reasons but it gives a sane take to  all 
the madness of the time. 146.94 was the defacto standard repeater channel 
that was perfect for the traveling ham because every city had a repeater on 
that pair.

BTW...I still have some Progline crystals just in case anyone wants to try a 
"new" repeater  ;-)

the microphone (TX-RX). now the cradle has a switch under the radio it says 
PAC-RT on and off...what does it mean for this setup? do i need another device 
to make it working as repeater, how to link it to a 800mhz spectra (if i 
needone) with this setup because the RSS for spectra have option for vehicle 
repeater, do i need to programm the device NTN1325B, do i need to program the 
mts2000 to work in the cradle as repeater, if i use a GTX how the GTX gets to 
work with the repeater. i also have MSF5000 working with all my devices and i'd 
like the msf5000 to hear the pac-rt (the vehicular repeater) working together 
with the spectra GTX and msf2000.
please keep on topic because i don't care what police department had what 
communications problems!

Thanks, all pretty much as expected. I'll fool around regarding battery. 

It does work and meet spec, clean transmitter, insides very clean. I'll have to 
come up with the blank code plugs and I know among the folks I know here in

[Repeater-Builder] need help IDing duplexer

[George C]

I have a Phelps-Dodge mobile type duplexer that must have been an OEM job, 
Model is 166C7487P3, was originally on 406-420. 

It is four cavities, RCA connectors, one female on the second cavity, and at 
each end a teflon cable to a male connector. Assuming the one on teh device 
(female) is antenna it just doesn't tune right. It looks like high pass side 
has about 20 db notch, other side at 60 db.

[Repeater-Builder] Motorola Suitcase Repeater data need

[George C]

Hi everyone.

I have a Motorola Suitcase P44SYS1180BT. Looks like it was modified to -3180 
(PL), clean mod. Can anyone confirm that this is based on a pair of MX320-S 
radios? I haven't had time to do more than a checkout and visual. No duplexer, 
it was originally setup on an impossible split for mobile duplexers (1.5 MHz). 
Battery never installed. Second thing I need to confirm. I have heard two 
versions of battery info. One is 8 Volt, one is 12 Volt. 12 makes more sense to 
me, but don't want to experiment. 

Lastly, I have the 450 MX pdf manual from the site here, but need original 
manual or a scan. I'm not even going to call /\/\ about it, I'm sure it isn't 
available. According to a posting on Batboard the manuals are:

Hello to the group.

I have a Motorola UHF GR300 repeater that I want to find a few parts for. I 
don't know the part numbers, yet. So I will try and explain them.

1) The cover plate that goes on the bottom and covers the Duplexer.
2) A cover plate the replaces the RICK.
3) The Zetron controller that was used or was a option for the RICK

And if anyone has UHF GM300 radios they would like to sell. :) 

Just want to rebuild this little repeater. 

You can email me at kc7...@yahoo.com
Thanks for any or all help.

Re: [Repeater-Builder] Repeaters vs RC

[George Henry]

No, the number of "channels" in an RC system refers to controlled functions 
of the aircraft, not RF channels.  For example, a plane with rudder, 
elevator, ailerons, throttle, and retractable landing gear would need 5 
"channels."  The system still only occupies ONE RF channel.

Re: [Repeater-Builder] Bendix King ERU4010B

[George Henry]

I'll take a guess from the "ERU" model number that it is a UHF repeater... 
innards might be those of the EMV4990 UHF mobile, which is programmed thru 
the mic jack with EMEDIT software (DOS) and a very basic programming 
interface (MAX232 and a couple of outboard components).  You might try 
checking with the Yahoo BK_RADIO group to be sure.  Software and interface 
schematics are in the group's file area.

[Repeater-Builder] Re: ROIP - Cheap

[George Csahanin]

Has anybody ever found a "cookbook" setup for this. I have a pair of 2600's, 
and the VIC-2E/Ms, and NM-1's, but it seems my IOS version is 12.3 and won't do 
it, plus, IOS, while fairly intuitive, has so many crankhandles that I get lost 
in the setup. 

It seems that while the hardware may be readily available ( a friend sent three 
2600's thta were being tossed out) the real issue will be IOS. About 8 years 
back a friend in DFW had this setup, but as a remote phone line extention. Same 
basic stuff. And you cannot beat it for reliability.

But for site link I use DRIL which is a modified "simpleh323" deal. Run it on 
CF card with a pair of Netier XL-2000 250 mhz computers. 

I'm also playing with app_rpt. The USB audio interface has issues. But for 
non-critical (amateur radio) applications, its ok. Maybe overkill for a link. 
Also trying limey-linux, have my first working build there. Not bad, no moving 
parts.

I picked up a Decibel DB4072 on E-Bay for only $100, and the seller even 
tuned it to my frequencies for me...  a much better option, if you have the 
flexibility to wait for a good deal.  (I couldn't get a mobile duplexer to 
move more than about 4 MHz without major degradation...)

Hi Tony, 

I have seen a situation where a section of thin aluminum plate 
was cut to fit on/over the original PL module. A Comm Spec 
TS-32 was placed on the Aluminum mount/plate with double sided 
tape and parallel interfaced with the original MSR-2000 PL 
module. The plate "stood off" from the MSR-2000 PL Module PC 
Board with classic threaded standoffs. Probably the 3/8 or 
1/4 inch length 4-40 or 6-32 size were used. 

Working from memory... I believe the original circuit only 
used the Decoder section (portion) of the TS-32 but I'm sure 
it wouldn't be rocket science to make encoder work (taking 
the encoder gate/mute on/of operation into consideration) on 
more than one CTCSS encoded tone. 

One might suggest a couple of contact Emails to the remaining 
Surplus Radio Dealers... I'd contact Ted at MDM and go from 
there... also posting a want on various yahoo radio groups like 
this one.

[Repeater-Builder] Fw: [DSTAR_DIGITAL] FCC Ruling on Repeater Definition

[George Henry]

Federal Communications Commission
Washington, D.C. 20554
March 23, 2009
DA 09-657

Mr. Gary R. Mitchell
President, Northern California Packet Association
P.O. Box K
Sunnyvale, CA  94087

Re:  Petition for Declaratory Ruling filed December 5, 2007

Dear Mr. Mitchell:
This is in response to the petition for declaratory ruling that you filed on 
December 5, 2007,
requesting that the Commission clarify the definition of a repeater in the 
amateur service rules. 1  A
repeater in the amateur service is defined as "[a]n amateur station that 
simultaneously retransmits the
transmission of another amateur station on a different channel or channels." 
2 You seek clarification of
whether the word "simultaneously" in the definition refers to the signal 
information being retransmitted,
or to the fact that the receiver and transmitter must both be active at the 
same time while acting on the
same signal information.   Section 97.205(b) of the Commission's Rules 
specifies the bands on which amateur repeater
stations may operate.  3  You state that some amateur radio operators are 
operating on bands other than
those set forth in Section 97.205(b) with systems that are essentially voice 
repeater stations, but that
digitize and retransmit the user's voice, on the theory that because there 
is a small delay in retransmitting
the signal of another amateur station, the signal is not "simultaneously" 
retransmitted and, therefore, the
system is not a repeater.  4  Prior to 1994, a repeater was defined as "[a]n 
amateur station that automatically retransmits the
signals of other stations."  5  The Commission revised the definition in 
order to clarify that certain
accommodations for message forwarding systems do not apply to other 
operating activities such as
repeaters and auxiliary stations.  6 The Commission proposed to define a 
repeater as "[a]n amateur station
that instantaneously retransmits the transmission of another amateur station 
on a different channel or
channels," but ultimately replaced "instantaneously" with "simultaneously" 
because commenters noted 
2.
that there is always a small propagation delay through a repeater.  7 As one 
commenter explained, "The
word `simultaneously' in this case means that the repeater is receiving and 
transmitting concurrently,
whereas each signal might be slightly displaced in time between receive and 
transmit."  8
To be able to repeat another station's transmission, a repeater must be able 
to receive a
transmission from another station and retransmit it.  Because the word 
"simultaneously" in the definition
is used to modify "retransmit," we believe it refers to a repeater station's 
transmitter being active when
retransmitting the signal received by the repeater station's receiver from 
another amateur station.  We
conclude, therefore, that "simultaneously" as used in the definition of a 
repeater refers to the receiver and
transmitter both being active at the same time.

Accordingly, IT IS ORDERED that, pursuant to Section 4(i) of the 
Communications Act of 1934,
as amended, 47 U.S.C. § 154(i), and Section 1.2 of the Commission's Rules, 
47 C.F.R. § 1.2, the Petition
for Declaratory Ruling filed on December 5, 2007 by Gary R. Mitchell IS 
GRANTED to the extent
indicated above.

This action is taken under delegated authority pursuant to Sections 0.131 
and 0.331 of the
Commission's Rules, 47 C.F.R. §§ 0.131 and 0.331.

Re: MSR-2000 

Moving the exciter is possible and probably not ultra hard 
rocket science. Moving the receiver down is not easy or practical 
and in some cases possible. I'd enjoy seeing a copy of the 
paperwork George or anyone else sends you...

I need to move a UHF MSR2000 exciter 450-470 down to 423.xxx. I am looking 
to see if anyone has done this and what Caps needed to be changed.
I looked in the construction files here but didn't see anything there about 
doing this.
Thanks for any info in advance

Re: [Repeater-Builder] BRAMCO Reeds

[George Henry]

Wa back when (~25 yrs.), I picked up a Bramco 2+2 decoder at a 
hamfest for $2.00.  Jumpered around the second decoder chain to make it a 
plain 2-tone sequential decoder and used it with a R/S scanner for my local 
FD dispatch tones.  Seems to me I used Motorola 'sponder reeds from a 
Pageboy in it, and it worked FB  Memories.....

BRAMCO reeds were made for a number of 2-way companies over the years, the 
color of the reed in meaningless. Each manufacturer selected what they 
wanted, light blue,  dark blue, red, silver, bronze, etc. likewise, coil 
impedances were variable as well, from 500 to 5K ohms. if you have the stock 
number, usually beginning with an "A0", I can probably tell you what you 
have. Decoders can be used as senders, however the drive is higher to get 
them to fire off reliably. note too that the Bramco reeds are position 
sensitive... especially below 100 hz...if you are going to use mechanical 
reeds for an application, try to get old Motorola "gold" reeds, TU217 sender 
and TU333 sponder, they were better in all aspects, especially sensitivity 
to close in the sponder reeds.

Didn't 'sponders have contacts on them. Or am I confusing them with other 
vibrating devices found in radios that are my age...??

[Repeater-Builder] Re: Scanning (was Re: Syntor X9000 Manuals)

[George Henry]

That's how I've scanned the manuals I've uploaded...  fortunately, I have 
access to a couple of Fujitsu flatbed scanners with document feeders that 
will handle the long pages, and in color, B&W, or grayscale.  (they are 
literally right outside my office door, in our medical records department)

I'd be more than happy to scan anything for the list, for just the cost of 
sending the originals back.

Re: [Repeater-Builder] Re: SCR-1000 crystals

[George Henry]

Exactly the problem...  so far, I have received copies of specs that say 30 
pF, 12 pF, and 8 pF load capacitance

sheesh...

Yep... and there are a few different varieties of oven type
assemblies. They can have different load specs and even
different (non standard) temp break points.

If you're shooting in the dark trying to order crystals...
good manufactures can take a very reasonable guess at the
crystal specs if you can supply a basic osc circuit diagram.
The trick is having the right diagram or drawing one up.

oh joy...

Re: [Repeater-Builder] SCR-1000 crystals

[George Henry]

Thanks to all who replied.  Apparently, sometime between the manufacture 
dates of our 2 repeaters, Spectrum changed something in SCR200 receiver 
oscillator, such that the load capacitance is substantially different.  We 
ordered crystals from ICM for the older of the 2, and whatever specs they 
worked from, the crystal would not warp down to freq without changing the 
trimmer cap value.

Our club has 2 Spectrum SCR-1000 2-meter repeaters (one from 1988 and one 
from the early 90's) which apparently have different crystal specs...  I am 
trying to find out the board revisions numbers or exact dates of 
manufacture, but in the meantime,  does anyone have the specs for the 
various revisions of the TX and RX???
