KB7YLU - Ted and his son KG7HUG - Chris (in the background) were at K7IOU's garage where yours truly and Dave did some work on an IRLP node computer scheduled to be installed at Northern Arizona University attached to the K7NAU repeater. Chris is a junior studying engineering at NAU.  We managed to get it hammered into shape enough that it can be returned back North to finish the installation.  Maybe we'll have some traffic from up there some day.

Our TEP RFI troubleshooter KD7AYQ - Gary retired a few months ago and TEP has not been too interested in replacing him.  They are aware of their responsibility for EMI and RFI, however, their replacement guy doesn't seem to have the required skills.  Please call their RFI Representative, Scott Dickerson at 520-275-9563 or the TEP Shop at 520-745-7119 if you have any noise.  The more they get pestered, the more they'll realize they need to take care of these problems.  Plus, if they don't the AZ Corporation Commission and other entities will get on their case.  So...CALL "EM!

Our man, Rick - N3RO, did a total remodel of his shack for the new year.  Looks pretty neat and functional, of course.  You can hear Rick nearly every day on the BART when he connects on his way home for lunch at 10:00 AM Tucson time.  You can find Rick on QRZ and he also has a website: http://www.n3roradio.com  Check it out!

The ailing 900MHz BART repeater was feeling ill and required some new duplexers and a total redesign of the band pass filters and other things and now it appears to be working better.  The cans are behind the nice black panel with the silver screws.  Can't see much, but they're there!

With a great deal of frustration and repetitive actions the 927.8875 repeater is one the air and integrated into the BART system.  The problem was just too many different colors of wires.  Anyway, it seems to be working pretty good.  It is located at K7IOU's place and seems to have good coverage.  Break out your 900 machines!

KC7JFC - Tony
Some time back the 94 hicupped when I turned the power off to see if it was guilty of creating noise on 75 meters.  When I plugged it back in, it wouldn't work.  In the process of troubleshooting it, I needed to find a Squelch Gate Card to see if it was the repeater or the controller.  Tony and KD7UIZ - Don were there and I mentioned that I had a spare but couldn't find it.  From that, Tony went on a hunt and yesterday at the Village Inn, he surprised me with important spare MSR-2000 cards he had scrounged up.  There was an R-1 Audio card, a Station Control card and TWO Squelch Gate cards.

Thank you Tony and whomever provided you with the circuit boards.  Maybe it'll be stable now that we have spares.

The crew got together and completed the 2nd stage of the tower project and for the most part finished the job.  The 220 antenna was moved to the top as opposed to being located at the same level as the 900 antenna.  The top guys were moved down, the semi rigid heliax was insatalled and the 900 machine was turned on and is operational.  W1KSZ - Richard was the first contact followed by KD7UIZ - Don, seems to work OK.  Next will be to interface the machine to the BART.  Afterwards, K7IOU provided hamburgers.  KB1EDU - Chad took off before the burgers.  You missed it, Chad! I think Fred ate yours.

So the other day, Dave - K7IOU says "What is that boatanchor stuff doing on the BART page"  So, I thought about it awhile and decided to create an AM page.  Announcements for hamfests and other related items will still be posted as required.  Ok, Dave?

Since we're going to have an addition to the BART repeater system, a 900 MHz machine, Dave thought it best to install a beefier tower to hold the additional monster 900 antenna, so we had a tower party yesterday. You can see it in what looks like a junk pile.  It's at least 12' long. Why so big when a quarter wavelength is about 3 inches?

Dave and I dropped the old tower the other day and he had already made a new mounting plate, part of it compliments of KE5SQC - Randy, and had two sections of the Rhon 25 standing already.  It was a bit warm, but a steady breeze kept things fairly cool and at least the tower is up, guyed and the 220 antenna is on.  School is still out as to whether it will be moved to the top of the tower or not.  N1DHS - Gary and WA0RTO - Fred did the climbing duty and it went pretty well with no incidents, if you get my meaning.  KW7RS - Rolly, KB1EDU - Chad and WA1BZQ - Bruce helped too.

More to come!

Our man K7IOU - Dave decided to present a BART participation award to our Arkansas Echolinker KE5SQC - Randy .  Of course, you all know that Randy lives in Fishook, Arkansas, Population 2.  So, here is the award:

The picture doesn't do it justice because it's really a LARGE "fishook".  Here's a picture of Randy and Mom holding the award to give a better perspective.  <Click Pictures to Enlarge>
 
When Dave asked Randy about Fishook, here's what he said:


Well there David, thats a very interesting question you have asked. Let me see if I can answer as best as I am able.... In the form as a Proper Noun, it would be spelled as I have in the past. As a place I live at the present moment in time and space on the Planet Earth in the Milkey Way Solar System South of the line just East of Sole Creek, Missouri and West of Rockee Pointe, Alabama it would be spelled as I do. Although you are compelled to think that you know I understand what you are asking, I'm not sure that you understand what I'm answering is not exactly what you most likely want to hear! Therefore it is most likely a diferentiation between what you see and what I spell may just make it more likely misunderstandable.The proper spelling for a Fish Hook is as spelled, Fish Hook. Now, if you were to take a trip, say to that place, just East of Sole Creek, Missouri and West of Rockee Point, Alabama, you would find yourself in Fishook, Arkansas.

  I hope this helps you to understand that I know what you have asked and hope that what I have answered, is, the proper answer in as far as I understand what you have asked. Although there are other answers to your very interesting question, I am sure, this only represents one of many other ways there may be to answer. Therefore I assume you understand that this answer will, most likely, only propagate other thoughts on how to answer your question.

 

         Randy,

            Fishook, Arkansas

One of our newest Jerry Bob's Breakfast attendees AE7YQ - Bill gave me a motherboard so I can build a spare computer for the IRLP/ECHOLINK/WIRES system.  Recently, KB1EDU - Chad donated a computer to the cause.  He had one that'd been rolling around in the back of his pickup truck for a while and he mentioned that he was gonna' take it to the desert and use it for target practice.  I talked him into giving it to me and I managed to coax it back to life.  So now, the computers on the BART will probably last a long time now that there are spares.

Yesterday was the 30th running of El Tour De Tucson, a 111 Mile and other Fun Rides bicycle race.  Local hams take responsibility for the manning and coordination of many aid stations and also assist the riders when needed.  The BART 146.94 repeater was used for handling traffic in Sector 2, primarily the North East side of Tucson.  Everything went smoothly and it appears that it will be doing it again next year.  Of course, the Echolink, IRLP and WIRES plus the links to the other repeaters were all shut down for the event.

So the door bell rings and it's the mail lady and she's got a small box.  Turns out it's from Fishook, Arkansas.  "What the heck is this?" I'm wondering.  I opened it and in there was a thank you card from "The guys in the morning", KE5SQC - Randy, K7GEL - Ken, N3RO - Rick, AB7IC - Tom and VK3JRE - Rex.  It said, "Thanks for all your work and expense.  A gift to show our appreciation for all you have done."  I can only assume it's for the "BART".  Well, it's my pleasure.  Only thing is, where am I gonna' find a belly big enough for this belt buckle?  What a deal!  Look at that case that Randy probably sewed himself!  The thing is 4.5 X 6.  I guess I'll mount it on a plaque.

K7IOU had a malfunction in his 224.74 machine and spent some time troubleshooting it and finally discovered the problem with a squelch gate card.  He felt so good about it that he decided to tempt fate and do a "re-organize" on the repeater, link radios and VoIP system computers.  It looks so neat that a gremlin might come in and try to do something .  We'll see !

5 June 2008

Dave - K7IOU has made a few changes to his system including the Echolink connect prefix and disconnect.   The connect prefix is * (star) and the disconnect is now # (pound).
An IRLP node has been added to his system.  The node number is 3033 and requires a "B" prefix in order to differentiate from the 3892 node.  The disconnect is B73.

And to top it all off, Dave has a WIRES-II node #1381.  So, the BART has two of everything. If you hear anyone connecting, please give them a call.  

As you might already know, the N7JND simplex node is connected to the BART 24/7.  Lee, WB9TPD has re-established his Echolink Conference server.  To connect to Lee's server, just DTMF 111 and you'll be there.  Enjoy !

We regret to announce the passing of Hobart (Bart) Paine, who passed at the age of 84.
Bart - K7CC was the original owner and licensee of the 146.34/94 repeater which is
part of the B.A.R.T. system.  Bart originated the B.A.R.T. many years ago and allowed it
it to be revived by the users of the system.  May he rest in peace.


6 August 2007

Dave - K7IOU has added an Echolink node to the BART system.  The node number is 22474 (not coincidental) and the access code to connect is: *C and the disconnect is ##.  What that means is you have to DTMF a *C followed by the node number you want to connect to.  Dave has some shortcuts installed and probably will share them with you.  Have fun !!


12 March 2007

Well, it finally happened !!  The Kenwood repeater is now installed, replacing the old
G.E. that has provided service for many years.  I have been thinking about it for quite
a few months now and, personally, I'm glad it's over.  Below are a couple of pictures
of the event, and click <here> to read the synopsis of the whole thing as it unfolded
since Gary turned over the Kenwood TS-820 Repeater over to the BART.  I didn't tell
it all because I wouldn't have anything to talk about at the breakfast meetings.

Gary - N1DHS, Dave - K7IOU, myself - WD7F and Fred - WA0RTO made the trip to the
Lemmon and installed the repeater in the same location as the old G.E.  Fred is a U.S.
Forestry Service communications guru and without his help it would not have been
possible.  Thanks, Fred !   It seems to be working pretty good, but that illusive crack-
ling is still there when the input signal is a little weak.  The new Motorola GM-300 link
that we installed Saturday seems to be keeping the AGC wrapped tight enough that
the crackling is less when the input to the repeater is via the 94 or the 74 machines.

There was only one snag.  When the pictures of the event are posted, you can see
that there was enough ICE on the dirt road up to the Lemmon site that Gary's pretty
Toyota Tundra (no 4-wheel drive) couldn't make it.  So, we unloaded the stuff into
Fred's company truck and we made it the rest of the way up the trail to the site.

A project is underway to replace the 448.350 repeater on Mt. Lemon with another
more modern repeater, specifically a Kenwood TKR-820 that Gary (N1DHS) has
had in service as 449.800 for several years.  Gary re-programmed the repeater, and
and it is in the possession of KD7TXO and WD7F for further tweaking. The repeater
has been modified to allow operation on 12 VDC as well as 115 VAC and prevent the
repeater ID and announcements to be linked to the  224.74 and 146.94 systems.  It
is operational on 448.350 at KD7TXO's QTH and has been encorporated into the
BART system.  As soon as weather and schedule allows, the repeater will be moved
to Mt. Lemon.

 The 146.94 (110.9) and 224.74 (136.5) repeaters are linked to the 448.350 (107.2)
Mt. Lemon repeater.   N1DHS, Gary, has allowed us to complete the link.  Thanks
to WE7H, we have an operational link radio, an ICOM-2720H, which Ed donated
to the cause.  There are many minor things to be ironed out, such as squelch tails
and audio levels, but it seems to be working pretty good just out of the box.  This
link will expand our coverage greatly over a large portion of Arizona.

Thanks again, Gary Matthews - N1DHS, for the use of your machine.


The MSR-2000 146.94 repeater is now linked to the recently completed & converted
Micor 224.74 machine. Every effort is being made to insure that audio quality is
maintained and it will not be apparent which
repeater is the source.  DTMF access
to the Voice over Internet (IRLP/ECHOLINK/WIRES) modes is the same as the
146.94 machine.

In January 2004,   Twenty members of the revised BART group

purchased a Motorola MSR-2000 repeater, CAT 250 controller,
RLS-1000 switch along with other items and presented to me to
replace the tired old machine in use at the time.   We're talking
major SURPRISE here!  I consider the repeater to belong to all.

HISTORY:

BART was originally organized by Hobart Paine, K7CC.  The original
group consisted of over 150 members.   Bart, K7CC, remains as well
as Don Brumbaugh, N7AEU.     I will attempt to locate a roster of the
BART group and post it and I'll see if I can find more members around.

Who the heck is BART?

BART is a group of Tucson Amateurs who operate and
control the 146.34/.94 VHF Repeater current located in N.E.
Tucson near the crossing of Harrison Road and Snyder Road.
To be more exact:  
N 32.17.39  W 110.47.28
                             
Grid Square:  DM42oh
                              Power at XMtr:  90 watts
                              Antenna:  Ringo Ranger ~50'
                              
BART, and the repeater as well, was rejuvenated to include
some new users of the .94 machine.  Bart Paine, K7CC,
started BART many years ago, and he is the last of the
ORIGINAL members.  You can be a member too.  Just
use the .94 repeater.  No dues, no fees to pay.  If you're
so inclined, send me a photo and I'll post on on the
Rogues Gallery!
The repeater is currently connected to WIRES (Wide
coverage
Internet Enhancement System) as Node# 1128.

It is connected to the IRLP (Internet Radio Linking Project)
system, Node# 3892.  Enjoy!

The repeater is now connected to EchoLink Node# 1125.
Wow!  We're gonna have traffic!

Here are some pictures of the new repeater
and IRLP, ECHOLINK & WIRES boxes.
They might not represent be the latest configuration.
