RE: [Repeater-Builder] How to disable a R-100 Watch dog timer?

[Juan Tellez]

I have done when use an external controller, completely disconnect the "big
board" and wire it direct to

RX/TX assemblies, if you got the manuals is easier.

Asunto: [Repeater-Builder] How to disable a R-100 Watch dog timer?

 

Hello,
Does anyone know of a way to disable or lengthen the watch dog timer
on the RX and TX of a Motorola R100 repeater?
I have bypassed the internal controller and am using a NRHC5 controller
along with external pl encoder and decoder.
It would be really nice to be able disable the microprocessor timers 
that the receiver and transmitter have. Has anyone gone about this
process? If so, how? As I understand it, the two timers are hardwired
in to the microprocessors and the count down starts when a monitored
data line changes state. Just moved the equipment cabinet into the house
and will be diving in with the logic probe and DVM.
I do have the service manual both hard copy and pdf.
If anyone has any tips or tricks on this repeater please let me know.
Thanks,

[Repeater-Builder] TS-64 on an MSR2000

[Glen]

Hello,

I just hooked up my new TS-64 to the MSR2000.  I did it this way:
Black to pin  1 Squelch Gate (GND)
Red to   pin 12 Squelch Gate (+V)
Green to pin 10 R1 Audio (JU1 removed) discriminator output from rx
Blue to  pin 13 R1 Audio, High pass audio out of TS-64
White to pin 14 Squelch Gate PL indicate, line pulled to +12 with 2K, and to
CAT500 PL input
Gray to  LINE PTT on MSR2000 backplane
Orange to CAT500 pin 10 DB25 PTT
Yellow to pin 11 Squelch Gate Tx Audio (TS-64 tone out)
Violet to pin 13 Squelch Gate (Local PTT) idles high, no local mic installed

I set the DIP switch as follows:
ON ON ON OFF ON ON = 141.3

The Squelch Gate card is removed.

Jumper clipping the White to ground mutes the MSR2000 audio.

Verified power going to TS-64.  TS-64 does not mute the rx audio.  With PL
indicate line high,
CAT500 attempts to transmit via PTT going to TS-64 PTT input.  TS-64 does
not take it's
PTT output low however.

Factory defaults on TS-64 jumpers, none set that I can tell.

It was my intention for the TS-64 to keep the White low until tone is heard.
Then it would
release that line, telling the CAT500 we have PL, then the CAT 500 would
key, then the TS-64
would key.  Upon CAT500 release of PTT, the TS-64 is supposed to reverse
burst and delay a little.

Thing works fine without TS-64 if I manually do PL indicate with a jumper
clip and hook
CAT500 PTT to Line PTT on MSR2000.

Any one out there that has experience with TS-64?  BTW I tried ALL the tones
on the input
freq.

[Repeater-Builder] Celwave Antenna Info

[Alan M. Maslin]

Hi ... I'm new to this group. 

I'm trying to figure out what type of repeater antenna our club has. No 
one in the club seems to know what it is and it's important that I find 
out. It looks to be a Station Master but it's not the large 20' 
version. It appears to be about 8' - 10' high. It's up at 75' on a 
tower so I can't get to it. I have heard that Celwave (or Phelps-Dodge) 
made a short version of a Station Master but I can't find any info on 
it. Wonder if any of you know what it might be. I primarily need the 
gain figure.

Thanks & 73,

[Repeater-Builder] 900 MHz link radios and 6M repeater

[wa1nh]

I am writing an article (time constraints will put it until next week)
about how I used an MT1000 low band (42-50) with an MVA as a remote
receiver, directly coupled (you should see where I found COR) to a GTX
900MHz mobile 12 watt (turned back to 5 watts and fanned)to link it 7
miles away.  I am using a Maxtrac 800MHz radio that was upbanded for
receive in 900MHz through a NHRC-5 to a maratrac transmitter set at 70
watts and fanned.  Except for the cor on the MVA ( which is pin 5 ),
ALL of the information was derived from Repeater-Builder.com.  Thank
you all for your articles.
Man this is gonna save me money on low band duplexers.

Thank you all for your responses to the question last week about the
GE master pro power supply.  I think I no longer need it.  Circle M

[Repeater-Builder] HELP! 2nd try GE Mastr II 900Mhz

[Dan]

I have in my possesion a true 900Mhz Mastr II repeater. I was so 
surprized to find it I didnt look around for any manuals.

Does ANYONE have information on this rare bird??? It has what looks to 
be a IDA controller and some kind of secondary board mounted on top of 
the cabinet. It is all true GE in the gold anodized cabinet, card cage, 
drawer unit.

Anyone??  help? point me to the info, would love to get this war horse

it has a IDA controller and another outboard control or interface on 
top of the unit. It is all true GE. As far as the little checking I 
have done it looks to have NO mods. Any one out there in Mastr II land

[Repeater-Builder] Celwave PD128-2T Tuning Instructions

[Harry Miller]

Does anyone have the tuning instructions for a Celwave PD128-2T 30-
54MHz antenna.  Contacted the manufacture and they say it's obsolete 
and they don't have instructions anymore.  I found reference that said 
the 2FT meant that it was "field tunable" with a hack saw and tape, but 
you needed the specific lenghts.

Has anyone had any experience with the antenna.  We want to tune it to 
52 MHz form a repeater.

[Repeater-Builder] Re: Yet another request for Help on a 6M repeater

[w6jll]

I've been working with 6M repeaters for some time, along with my mentor (ELMER) 
- just a 
friendly word of advice regarding the Mastr Pro. The receivers are great but 
the EP38 can 
have some real problems. You MUST change the HV caps - I've done so - the total 
cost is 
about $50, not to mention the time involved. Then, you are dealing with a very 
very heavy 
power supply tube multiplier and final. Be wary of the "stacking" relay that 
combines the 
HV, yours is likely dirty by now and will require attention. The antenna relay 
is virtually 
impossible to find if yours fails. Also, the 10V regulator may require some 
attention as the 
caps may be bad. Be absolutely sure to bring your up to power slowly and check 
all of the 
voltages before you hook up your strips.

In brief, think twice before putting that behemoth on the air. Unless you have 
a real 
sentimental attachment to Mastr Pro (I did, mine was given to me by my then 
Elmer. now 
an SK), there are a better (and easier) choices. A Mastr II or MII Exec 100W 
can be had for 
about $50 from any one of a number of reliable suppliers. The 100W version is 
great, 
because by disabling 2 of the 4 final devices you get left with a solid 
continuous duty 50-
60 watt radio that will play all day, and well into tomorrow. You also get a 
solid state radio 
with components that are likely 10-15 years newer than your Mastr Pro. If you 
are paying 
rent (as I do here in LA) by the amount of rack space you occupy, the Mastr II 
or Exec II 
will be much cheaper than the EP38 which takes up a lot of room. Also, if your 
landlord 
sees those tubes he may surcharge you for electricity.

Just a few thoughts. Been there, done that. But that's what its all about. Have 
fun.

Well if you can hear a commercial FM station coming through your repeater it

  Good morning on this soggy, Friday Morning.



  We've been experiencing a recurring problem every once and a while. It's
not our repeater, but its driving me nuts trying to figure it out. It sounds
like badly tuned can's, somehow feeding the output back into the input.
Except, it isn't from our repeater. And it covers a wide area. I've heard
another repeater being bothered by this and also a local commercial FM
broadcaster came through. If I turn our repeater off, it's still there. ( I
said I was trying anything.)

  Do you guys think trying to use direction finding equipment might produce
some results??

  Oh, this noise is so strong, even my signal at 25watts at a distance of 4
miles won't trigger the repeater!



  Any ideas??

Re: [Repeater-Builder] NHRC-3/M2 Processor Noise

I mentioned that I have the audio amp disabled.  I do this by sliding a piece 
of Teflon tubing down over the pin that supplies power to the audio amp.  It is 
easy enough to pull the tubing back off and use the amp for desense testing by 
doing it this way.

I think I picked up this method for disabling the audio amp here on the

[Repeater-Builder] Just say "no" to Grouply

[skipp025]

Evidently there's a new "service" called "Grouply".  It offers 
to put all your Yahoo-Groups onto one page and somehow merge 
all the messages in a way that makes it easier to navigate. Most  
think Yahoo's method is fine just as it is, so many don't bother
accepting the invite.

However - some hams are, in fact, signing up for "Grouply".  
Grouply accesses Yahoo groups in two ways.  You can tell Grouply 
which groups you belong to, in which case Grouply attempts, 
automatically, to join all those groups.  Or, what most folks 
do, is they simply tell Grouply their Yahoo name and password, 
and Grouply "retrieves" all the new messages for whatever method 
of presention.

But here's where it gets ugly - Grouply then accesses the 
member database of groups who have not kept it hidden, and 
sells those email addresses to spammers...and, if they have 
someone's Yahoo account name and password, they have access 
potentially to a LOT of other personal info.

Not sure how to prevent this from happening on repeater-builder 
some group moderators are making public announcements, asking group 
members to not use Grouply to view their Yahoo group.  But in fact, 
if "method B" is chosen by the Grouply participant, moderators 
will never know if "Gary K6XYZ" accessed the group himself, or if 
Grouply posed as Gary to do it.

Anyway, if the question comes up, "Just say no" to Grouply.

I posed this question to the NHRC Group with no response.  I wonder if 
someone here has an answer?

I have a NHRC-3/M2 controller installed in a Mastr II mobile and have
had it in service for several years. It has a high frequency noise or
whine that I can hear and shows about 200 Hz deviation on the service
monitor.

I am wondering if there is a ground strap that can be added either to
the board or to the radio that will reduce this noise. I have the
audio amp disabled so that is not the source of the noise.

I am just returning this controller to service and would like to
reduce or eliminate this whine. Maybe some kind of rebalance of the
audio levels is possible to help?

Thunderbird has a *lot* of settings in the advanced section of the 
options. You can probably make it do anything.

Re: [Repeater-Builder] RE: Strange oscillating noise problem.

[DCFluX]

The actual carrier is 145.25, which is cable channel 18. You would
hear a buzzing sound but only on the output, it wouldn't go through
the repeater.

Hmm, Cant find a VHF manual for the VXR-5000, do you know what the 1st
IF freqency is? In the UHF it is 47.9 MHz which seems goofy to me but
may be something else. Even so 144.63 - 49.7 = 96.73

Can you provide the model and frequencies of the UHF repeaters?

RE: [Repeater-Builder] RE: Strange oscillating noise problem.

[Richard MI Ranta]

Sorry, I should have provided more info.

The repeater is a Vertex Standard on a frequency of 145.230 mhz out, 144.630
mhz in.
We have moved the repeater since the photographs displayed on the web site.
We're now using a Antenna Specialist 711 ( I hope I have that model number
right), brand new, and about 140 feet of Andrews Hardline.
I too think it's intermod, and have been entertaining the idea that there
could be a dirty pager around here somewhere. 
We had the can's tuned by a professional ( if you go to our links page,
click on T & W- they are also our landlord. Great folks!)
I also have heard this noise ( I wish I could be more accurate with it.
Perhaps I'll record it the next time it starts and put a link up here so you
can hear it) on two UHF ham repeaters also.

Good morning on this soggy, Friday Morning.

 

We've been experiencing a recurring problem every once and a while. It's 
not our repeater, but its driving me nuts trying to figure it out. It sounds 
like badly tuned can's, somehow feeding the output back into the input. Except, 
it isn't from our repeater. And it covers a wide area. I've heard another 
repeater being bothered by this and also a local commercial FM broadcaster came 
through. If I turn our repeater off, it's still there. ( I said I was trying 
anything.)

Do you guys think trying to use direction finding equipment might produce 
some results??

Oh, this noise is so strong, even my signal at 25watts at a distance of 4 
miles won't trigger the repeater!

 

Any ideas??

I see from your club website that you are running braid/foil coax and RG-213 as 
jumpers to the duplexer. You might want to consider a change to heliax for the 
antenna run and superflex heliax to the cans.

That said, you may still have other issues at play. But it's always best to 
clean house first.

Tell us more about the repeater, like the frequencies. Also if you are
hearing it on the output it is most likely intermod or a mix.

When considering occupied BW, that's only part of the equation.  Modulation 
bandpass is important too.  Here in SoCal on 2 meters we specify a 3 kHz 
cutoff, with all modulation products down 20 dB @ 4.4 kHz.  Unfortunately 
that makes "flat audio" an impossibility, but that's the price to pay for a 
proper 15 kHz spacing implementation.

The users of this particular system are pretty advanced and already have P25 
Radios. I think this would be a minimal issue.

I Agree. However the requirement for this opportunity is that the equipment be

Not to knock D-Star, but I am personally tired of being beat about the head 
with D* D* D* every five minutes on both groups, the air, and at Hamfests. I 
made the mistake of joining a Digital ham & D-star yahoo group (just trying to 
stay up on things) and my inbox was never the same.


That being said- again the requirements of the opportunity is P25 capability. 
Along with that all the users of the system have P25 rigs and are itching for a 
good P25 Capable repeater around here too.

I would not consider any digital right now if it was not an requirement of the 
opportunity. My feelings are most Ham repeaters are made up of surplus 
commercial grade equipment of the past, so in 10 more years you will not find 
any commercial D* equipment floating around, but P25 will be abundant.

Also, if Icom was so sure of the format why would they not offer it 
commercially along with or as an alternative to P25? Other manfactuers are 
introducing their own formats besides P25. I am hesitant that D* has a shorter 
lifespan than P25 just due to the fact the commercial world is P25 and that 
equipment will be around a while.

Hey

If your looking for pass through as is audio check out the ICS controllers.
The audio quality is quite good.

[Repeater-Builder] NHRC-3/M2 Processor Noise

[Jim Brown]

I posed this question to the NHRC Group with no response.  I wonder if someone 
here has an answer?

I have a NHRC-3/M2 controller installed in a Mastr II mobile and have

had it in service for several years. It has a high frequency noise or

whine that I can hear and shows about 200 Hz deviation on the service

monitor.



I am wondering if there is a ground strap that can be added either to

the board or to the radio that will reduce this noise. I have the

audio amp disabled so that is not the source of the noise.



I am just returning this controller to service and would like to

reduce or eliminate this whine. Maybe some kind of rebalance of the

audio levels is possible to help?

Five?  Try over a dozen... And sometimes double or even
triple that.  See 
and count the hops from Los Angeles to Santa Fe NM.
Then do a hop count from Carson City NV to Corpus
Christi, TX or even to Austin.

I've heard a conversation on the LA to Santa Fe path, and
you'd swear that the guy in NM was on the local machine
(except for the squelch tails when the links drop - and BTW
the controllers and the links are all full duplex).

Remember every solid red line is an RF hop, and every dot
is a repeater.  Some of the systems are VERY complex,
just count the lines going into a dot and then add the local
UHF repeater port(s) and the remote base port(s) as they
aren't shown.
The dashed lines are non-RF hops (some are piggybacked
on corporate T-1s).

Re: [Repeater-Builder] Re: Comspec TS32P encoder control (CAT Audio)

[Bob M.]

This is getting slightly off the original topic...

I suppose some mild amount of equalization can help, but it can also be 
implemented completely incorrectly and cause a lot more harm than good.

Case in point (Dave M, start laughing) is a local UHF repeater. The trustee has 
a slight hearing problem (loss of high-freq) and almost all of the users have 
Yahoo handhelds (VX2s, etc). Naturally there's an EchoLink port and multiple 
receivers, and links to just about everything in the area. The main repeater 
has had its pre-emphasis, audio filtering, and limiting defeated and a stereo 
EQ feeds it. Basically it is a straight line from -20dB at the low end (20Hz) 
to +20dB at the high end (20kHz) using both channels in series, way more than 
the standard 6dB/octave pre-emphasis, and no low-pass cutoff above 3 kHz. No 
test equipment was used to set up levels; it was all done by ear in an attempt 
to get FM broadcast-quality audio out of a 1 inch speaker.

So with no limiting or low-pass filtering, the repeater puts out strong 
sidebands up to 20 kHz away, pretty much ruining any use of another repeater 
that's the reverse split, 25 kHz adjacent, and 13 miles away. A deviation scope 
shows peaks out to 7 kHz, but a spectrum analyzer shows a much wider bandwidth, 
almost all of which is high-frequency noise from marginally weak signals that 
gets amplified way out of proportion to the actual voice audio.

So if you must use an EQ, make sure the transmitter still has the final word on 
pre-emphasis, low-pass filtering, and limiting.

Re: [Repeater-Builder] what does this email mean?

[Chris Carruba]

Kevin,

Something to chew on ...

I work at a elementary school.  I manage 3 to 4 classes of  25 or more students 
(aprox 100 students) at a time.  There are MANY times that a few are disruptive 
and action needs to be taken.  However I am firmly against punishing the whole 
group for the actions of a few... instead I punish those involved in the 
incident.

You asked - What does it mean?
It means some didn't like the way I handled a recent explosion of 
off-topic email and the way I handled the members that would not listen

Re: [Repeater-Builder] Re: Comspec TS32P encoder control (CAT Audio)

[Paul Plack]

I think this gets debated because the downside of audio processing bothers some 
repeater ops more than others.

If you used 20 dB of audio compression in the audio path, you could give pretty 
much all users the same deviation on the output. You'd also suck up 20 dB of 
noise on weak signals with low audio, and have a really annoying "pumping 
effect" on fully-deviated users unless a long delay was used on the decay side.

If you used multi-band audio processing to make the spectral distribution of 
various users' audio more consistent, it can have some really odd artifacts. 
Back in the 70s, many AM broadcast stations began processing bass separately to 
deal with the annoying pumping effect common when playing disco records. Later, 
as processors evolved to more bands, this technique became a popular weapon in 
AM broadcast "loudness wars." Now that most AM broadcast stations have moved to 
spoken-word formats, they've kept their multiband processors, and many of them 
make newspeople sound like they always have a cold at best, and like trained 
ducks at worst.

One downside I haven't seen mentioned regarding the use of outboard equalizers 
is the greatly increased potential for ground loops in the cabling. Three-foot 
unbalanced coaxial audio cables terminated in RCS plugs can be bad news at a 
site with lots of RF around. If your own FM transmitter gets into the audio 
harness, it can cause very subtle distortion which isn't always intuitive to 
track down.

I think the best thing we could do to make repeaters sound consistent would be 
annual "green screwdriver nights" to get everyone's rigs set up properly with a 
service monitor. Clubs used to do this all the time, but it seems to have gone 
out of style.

If we could make all users sound great with audio processing on the repeater, 
what happens when the user whose audio is 20 dB low has to operate simplex from 
a fringe signal area during an ARES activation?

This is definitely a "religious" debate amongst folks.

Very odd.  Gotta love e-mail.  Everyone can have their own

I'll share a few other quick thoughts about mail, mail clients,  
servers, etc...

Thunderbird is great, as I mentioned before, but be careful when you  
start experimenting with multiple mailers to see what you like.  The  
vast majority of folks on the Net are using their ISP's mail service,  
and most ISP's do only POP3 protocol.  POP3 was originally designed as  
a system that allows you to get your mail off of their server, and in  
the process it removes it after it copies it to your local MUA as us  
old Unix mail geeks call them.  Mail User Agent.  The software you  
read your mail in.  (MTA = Mail Transfer Agent, that's the software  
your ISP runs to move the mail from one place to another.)

Later POP3 clients added the ability to "Leave mail on server".  They  
did this by telling the server "I didn't really get that last message"  
even though they did.  This is why if you've got multiple computers  
and you choose "Leave mail on server", things like your "new mail"  
flags and stuff just don't work right between machines.  Later POP3  
servers added real "support" for doing this right, and all of this  
"magic" is pretty much hidden from the end-user by their MUA.   
(Outlook Express, Thunderbird, Eudora, whatever.)

When you're testing new mail clients -- you want that "Leave mail on  
server" feature turned on from the start in any new clients you point  
at your ISP's mail server.  Otherwise, you're going to be ultra- 
frustrated by the fact that your new toy you're playing with just  
downloaded all your new mail into itself, and the next time you open  
whatever "old faithful" client you've been using... none of that mail  
shows up.  "No new messages on server"... Hey, wait a minute!  Where'd  
those messages go?!

So be careful when trying out new things.

Of course, the Internet geniuses figured out there was a "better way"  
and created a protocol called IMAP later on.  IMAP mail servers are  
unique in that the client gets a COPY of the message but does NOT have  
to delete it off the server.  IMAP servers also usually understand the  
concept of mail "folders" that are up ON THE SERVER, not just a folder/ 
directory that the local MUA creates to give you a "view" that looks  
like your mail is neatly sorted into folders locally.  The problem  
is... for ISP's and mail providers, that people don't delete e-mail...  
it gets "saved" for later review by many people, and this means DISK  
SPACE on the server if you're offering IMAP to your customers.  So  
most don't.

I *highly* recommend it, if you can find a provider with IMAP  
capability, to use one.  With one caveat.  Gmail.  Gmail (as many  
know) has both POP3 and IMAP support, but it's hideously weird.  If  
you "tag" a message via the Gmail web interface with a "topic" name,  
that becomes a "folder" in IMAP.  It's just downright odd, unless you  
like it.  I don't.

Here, I've been running my own MTA mail servers for years so I  
have IMAP.  I open Thunderbird on the Windows machine, or Mail.App on  
the Mac, and every message is right where I left it... in the Inbox,  
in the "Repeater-Builder" folder, etc.  In fact, the mail SERVER sorts  
the incoming mail and Repeater-Builder new messages go DIRECTLY into  
that folder... they never hit the Inbox at all.  It's AMAZING when you  
can do this type of server-side filtering and combine it with IMAP on  
the clients.  After that, ANY IMAP client displays your folders and  
your messages the same... and they're all "synced".  I can have the  
Mac on the desk next to the Windows machine and the next time both  
check for new mail on the IMAP server, they both show that there's new  
messages in whatever folders they're in.  If I remember right, even OE  
could do IMAP.

(Another gotcha to know... you'll see providers say they have "IMAP4"  
support.  IMAP4 *usually* refers to Microsoft Exchange servers (an  
MTA), talking to Microsoft Outlook (the full blown, not Outlook  
Express, version.)  IMAP4 is generally compatible with all regular  
IMAP clients, but you often pay too much for that extra
