TARC D-Star Repeater Update
The TARC D-Star repeater,
on 443.000mhz is up and running with the network connection working
good. We still have some packet loss between the tower and the
gateway computer, but I've tried to decrease the packet sizes by an
increase in the hopping frequency so that noise or problems on one
segment of the 900Mhz band has a smaller impact on the total quality of
the audio being transmitted across 900Mhz.
I enjoyed the D-Star web program put on over last weekend of Dec at the http://www.w5kub.com/
web site. It had a lot of great information in it. There
are reruns still available on that web site. There were a couple
of times that audio cut out as they changed speakers or at the start of
a session, so just hang tight what that happens in the replays, and
you'll get audio back shortly.
I currently have 443.000
connected to reflector REF014C. Reflectors are internet connected
hubs which handle the large bandwidth needed for lots of users being
"internet" connected to one or more repeaters. If you want to
connect to a different reflector, you can use the 'unlink' mechanism by
sending a 'U' in position 8 of the UR call field. The list of
possible reflectors can be located on the internet by searching for
"dstar reflectors". The http://www.dstarinfo.com/reflectors.aspx web page is at the top of the results.
To connect to one of the reflectors, set the UR call to the reflectors name with an additional 'L' character in position 8.
Each of the reflectors
listed, has a "Usage" description of it, and location information
etc. You can click through the links there in your web browser,
and see which repeaters and users are connected to which reflectors.
There was a lot of
information provided on the DV-AP and DV-Dongle devices. These
devices are internet connected dongles which allow you to use D-Star as
The DV-AP is an "access
point" like device which you connect to your computer. It has a
low power FM transceiver on board, which you can talk through, with
your conventional FM equipment. That device provides the D-Star
CODEC to encode/decode your voice for D-Star. It then gateways
your transmission into the reflector/repeater which you've used your
computer to connect to.
The DV-Dongle is also
connected through your computer, but requires you to use a headset for
your audio in and out. If you are setting near a computer, and
can stay there, then this device can make it possible to get into
D-Star with that simple restriction on your movement.
Both of these devices can be found on the internet at the various ham radio equipment stores.
The DRATs application was
also reviewed. DRATs allows you to use your D-Star radios digital
data services to send text messages, transfer files and other related
data services. It is a great ARES resource for support activities
because you can use your D-Star radio, as you would a TNC, and this
application provides all of the "applications" without you having to do
the extra work to manage your data transfers manually.
There are lots of D-Star nets being run world wide. There is a list at http://www.dstarinfo.com/nets.aspx
which you can review to see if there are some interesting topics which
you'd like to participate in. If you have a DV-Dongle, you can
sit at your computer and connect to these nets and participate
directly. With the DV-AP, you can also connect via your computer,
but be able to use your FM HT, around the house to participate.
If you want to use a D-Star radio, then you can check for any activity
on a local repeater, such as the TARC 443.000mhz. If there are no
other users who need the repeater for something else, then you can
simply link the repeater to the appropriate reflector and participate.
This coming year, I will
be taking some time to do some D-Star demonstrations and programs at
the club meetings. If you have an interest in D-Star, feel free
to send me an email to email@example.com and I can try and provide some answers or pointers to answers.
The TARC repeater systems have been undergoing several changes,
upgrades and new equipment over the summer. Here's the low
on what has been happening.
- A new Repeater System on 147.045mhz
and Installed in Mannford, at the 442.000mhz site, and the old Lookup
Mountain machine was used for the new 147.180mhz repeater mentioned
- A new 145.110mhz System will be brought on line
Lookout Mountain on the old 147.045mhz system's antenna sometime before
the end of October if all goes well.
- A new 147.180mhz repeater is now online in east
Tulsa at the 443.850mhz site.
- A new D-STAR repeater was acquired and
installed at Lookup Mountain on 443.000mhz.
- All around the greater Tulsa area, there are
digi-peaters which are in place, to help eliminate the single
dependency on ETULSA which is now offline so that it's antenna system
can be used for the 147.280mhz system.
We owe a big thank you to the generous contributions of money, time and
effort by Bob Buford, Jerry Moyer and some of their coworkers, as well
as some matching funds, courtesy of their employer,
Conoco/Phillips. If you see these folks, please
give them a
thank you for helping the club extend and maintain its equipment.
The D-STAR system on 443.000mhz was obtained for "free" due to a
program that ICOM has had to try and extend the use of D-STAR by
providing repeaters, which might encourage people to use or buy D-STAR
capable radios. There are lots of things to read about
the Internet. Here are some things that D-STAR provides to
Amateur Radio operator.
1. Station to station communications, through repeaters via Internet
linking. This is similar to echolink's capabilities, but it
digital, and more dependable in implementation it seems. We
working on finalizing the internet services connection to the repeater
site so that we can make use of these linking facilities. The Gateway
to repeater link for the 443.000mhz machine is experiencing some spotty
operations due to the quality of the antenna system we currently have
access to at the repeater site.
2. Call sign routing allows you to just say you want to talk to another
Amateur station, and you don't have to know what repeater they are
using. That information is stored in the global D-STAR
and the Gateway computer system, attached to the repeater, has access
to the information about all stations, and will select the gateway
repeater on the other end to connect you through.
3. Much like echolink conferences, there are D-STAR reflectors, which a
repeater can be connected to so that larger "systems" can be created
and interest specific nets can include many more stations.
4. At the top end of the system is the 1.2Ghz and higher linking radios
which allow Ethernet connections into D-STAR so that it can be used
"across" town, to provide a wide-area network. The lower
frequency radios provide data services at lower speeds, and use serial
data connections into the radio.
To use D-STAR effectively, you need to create an account on some
Gateway computer somewhere in the world. Generally, it's a
idea to have your account on the repeater system in your hometown, or
some place where you usually hang out. Having your account on
that repeater system, will allow you to use D-STAR more fully.
Noid, NM5I has also setup a D-STAR repeater on 443.025mhz at 36th St.
North at the Police station. Noid is trying to finalize the
operations of the Internet connection to his repeater as well.
To read more about D-STAR, you can look over some of the associated web
sites such as the following:
1. ICOM D-STAR Information http://www.icomamerica.com/en/products/amateur/dstar/dstar/default.aspx
2. ICOM ID-1 radio for 1.2Ghz communictions http://www.icomamerica.com/en/products/amateur/dstar/id1/default.aspx
3. ICOM 2820H - D-STAR optional radio http://www.icomamerica.com/en/products/amateur/dstar/2820h/default.aspx
4. ICOM IC-91AD dual band HT http://www.universal-radio.com/catalog/ht/0091.html
5. ICOM D-STAR repeater hardware http://www.icomamerica.com/en/products/amateur/dstar/2000_4000/default.aspx
6. D-STAR users web site
7. D-STAR Information Site http://www.dstarinfo.com/
There are lots of other sites around the Internet, and you can find
lots of stuff linked to by the #6 and #7 links
you have questions about how to use the local D-STAR repeaters, trying
asking on the local nets, or on other repeaters.
Most of the D-STAR radios support both D-STAR and normal, analog FM
emissions, so that you can use these radios for existing
repeaters. There are a couple of D-STAR repeaters
and of course all over other states and areas of the world.
information at the link #6 above (dstarusers.org), reveals more about
all of the D-STAR repeaters in the U.S.

to make sure there are no "rumors" being spread:
fire marshall ordered the repeaters (plural - also involved is the
443.000 UHF machine - the one that is not on the link system)
"unplugged", because they were being powered by an "extension cord"
that was not rated for the amount of power they draw.
a. This is technically not the case, because (1) 443.000 was
actually down, and shouldn't have been counted, however the fire
marshall doesn't see it that way - it WAS plugged in.
b. Both repeaters are powered by one 13.8V power supply, so
it is substantial, it actually only draws 4 or 5 amps even if both
repeaters were transmitting, therefore the cord was actually still well
within its ratings - basically, the fire marshall didn't "do the math",
he just decided to be hard-nosed about it.
fire marshall (and the building owner's) position in this case is
understandable - this inspection was shortly after TWO fairly
spectacular fires in the building!
the extension cord may not have itself been a fire hazard, it is NOT
code - no permanently mounted equipment is supposed to be powered by
extension cords in a commercial building, PLUS no outlet is supposed to
be installed in a closet (too easy for them to be damaged because they
are "hidden", plus they get missed in inspections). So in
case, the extension cord is to reach a "working" but illegal outlet
because the "close" outlet we used to use was pulled out when another
tenants equipment was removed.
we are negotiating with the building owner - we have an electrician who
has done a quote for the work required to restore the original outlet
to operation while at the same time bringing it up to code.
we have to work with the building management company to get their
approval, then the city to get a permit and then inspections.
issues with the "lease" of this space and paying for power.
building has changed hands (or at least management) since this space
was originally donated to TARC, and apparently the records (if any)
were lost. In conjunction with getting the permit/building
modifications negotiated, we will also renegotiate the lease.
However, we're dealing with not one, but TWO bureacracies here, and
these things take time.
meantime, normal TARC operations (nets, special events, public service
events, etc.) are held on the 147.045 repeater (positive offset, 88.5
patient, once we get the legal side worked out, it should take us (or
rather, the electrician) about an hour to actually get us back on the
air - once he gets an okay from the building owner and the city.

made of 3/4" EMT conduit, wood and wire, and is designed to be ground
mounted and guyed with rope. It can be set up in 5 minutes
packs in a 4' 6" by 4" tube.
The conduit will be pre-cut into the appropriate lengths - base, 10m
top, and add-on stubs for 12m, 15m, 17m and 20m. Switching
is done by adding the stubs with couplers, with each lower band
requiring all the stubs for the higher bands. The lengths
cut for the middle of the SSB portion of each band, but tuning down for
CW can be handled by adding a short (2" to 6" as needed) tuning stub to
The kit is the wood base, conduit (pre-cut and drilled), couplers,
conduit straps, screws, ring terminals, and radial wires (8), plus a

of the goals
of the ARRL is education regarding amateur radio, with the intent of
bringing new licensees into the fold. As a special service club, the
Tulsa Amateur Radio Club strives to do the same in many ways. One
obvious way is through licensing classes, but there are other ways we
can reach out to non-hams as well, such as holding events in public, or
giving presentations to other community organizations.
