Route 66 On The Air Guidelines

QSL to
Tulsa Amateur Radio Club
P.O. Box 4283
Tulsa, OK  74159-0283

Have you ever been on the receiving end of the pileup?  Or have you ever wished you were?  Do you get frustrated at Field Day or during contests when you call and call and it seems like the "dx" never hears you?  Well, have I got the event for you.

Route 66 on the Air is a week long event (7PM Friday, September 10th through 7PM Sunday, September 18th) where every area ham can experience being the Rare One that everyone wants to talk to.  The event commemorates the Mother Road - Route 66 from Chicago to LA.  This year 20 (18 permanent and 2 rovers) stations will have sequential 1x1 callsigns from W6A in Long Beach, CA to W6Q in Chicago.  (W6R is new - in Springfield, MO and with Bob Heil as a guest op and W6S and W6T will be rovers mobile on the route).  We (the Tulsa area) will be W6L once again this year.

This event is open to ALL area hams.  If you have HF privileges, you're eligible - and 10 meters has been open of late, so even the Techs can get in on this one.  Even if you don't have HF (privileges or equipment) you can still get involved.  For one, VHF and UHF contacts count.  For another, many of the area hams with HF stations lose their voice by the end of the week, and would gladly let you use their station.  All you have to do is ask.

Since the sponsoring club (the Citrus Belt ARC in Orange County, CA) awards a clean sweep certificate for everyone who contacts all 18 regular stations (the two rovers don't count for the sweep), there are a ton of people on the air from all over the country - and even the world - who are looking for all 18 stations - and that means they're looking for US.  I've never had to call CQ for long before generating a pileup and last year worked over 400 stations - and there were more calling than what I could work every time I got on the air.

This is event is open for all bands (even VHF and UHF) and all modes, so there's plenty for everyone to do.  And it's open to all hams, so tell your friends even if they're not TARC members or don't live in Tulsa - all they have to have is the ability to hit a repeater on the UHF link system and they can join in.

All we ask is that first, you keep a log of at least the callsigns of those you talk to with the date and (approximate) time of the contact.  Paper, spreadsheet, or logging program export will work.  Operator name, city, state and signal reports are all optional (but nice to have).  Second, to avoid confusion (since we can't always hear each  other - being so close together) that we only have one station using the W6L call per band/mode at any one time.  So if you want to give it a try, call on the UHF link system first and ask if anyone is using W6L on your band and mode of choice - and if no one answers up, it's yours.  Keep listening though, in case someone calls asking for the band/mode that YOU are on.  And please share - some of us work so we only get to play radio in the evenings, so if you've been on all day, don't monopolize the "best" bands in the evenings, too.  We especially need CW and digital ops, and also people that can work the lower bands - especially 80 and 160 meters for the close in stations where 20 and up will go right over.

Suggested frequencies are those ending in 66 (or 33 for CW), so 14.266 and 21.366, for example.  But with 19 other stations, don't be surprised if everyone from 14.250 to 14.280 is calling "CQ Route 66".  Just find a clear spot and throw out the call.

If you need any tips or have any questions, feel free to contact Bart N5TWB or Gregg W5GGW for more info.  And if there are any disputes regarding the W6L call, Gregg has the final say - since his name is on it.

TARC D-Star Repeater Update
January 2013

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 well.

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 w5ggw@cox.net and I can try and provide some answers or pointers to answers.


TARC Repeater Update
December 2012

The TARC repeater systems have been undergoing several changes, upgrades and new equipment over the summer.  Here's the low down on what has been happening.

  •  A new Repeater System on 147.045mhz was created and Installed in Mannford, at the 442.000mhz site, and the old Lookup Mountain machine was used for the new 147.180mhz repeater mentioned below.
  • A new 145.110mhz System will be brought on line at 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 new APRS 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 D-STAR, on the Internet.  Here are some things that D-STAR provides to the Amateur Radio operator.

1. Station to station communications, through repeaters via Internet linking.  This is similar to echolink's capabilities, but it is digital, and more dependable in implementation it seems.  We are 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 system, 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 good 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 http://www.dstarusers.org/

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 above.   If 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 in OKC and of course all over other states and areas of the world.  The information at the link #6 above (dstarusers.org), reveals more about all of the D-STAR repeaters in the U.S.

DIY Vertical Antenna Kit

The Portable-Convertible-Vertical that was the presentation at the July TARC meeting will be made available in kit form at the Ice Cream Social club meeting in September.  In order to take advantage of quantity discounts, we'll be collecting pre-payments for the materials through the August club meeting (August 19th).  The cost is $20.  Quantities are limited, so first come, first served.

For those that missed it, this antenna is not an antenna for permanent mounting, but is rather a portable quick setup antenna suitable for emcomm or similar use on 10-20m including the WARC bands.  It's 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 and 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 bands is done by adding the stubs with couplers, with each lower band requiring all the stubs for the higher bands.  The lengths will be 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 top.

The kit is the wood base, conduit (pre-cut and drilled), couplers, conduit straps, screws, ring terminals, and radial wires (8), plus a PVC ring for the guy ropes.  Building requires a screwdriver and crimpers or soldering iron and takes 15 minutes.

Eastern Oklahoma / Northwestern Arkansas Skywarn

As you may or may not know, the TARC is involved with the Skywarn network of community service oriented clubs. The W5IAS linked repeater system is the largest, the best and most efficient repeater system in the State of Oklahoma. When emergencies arise in our areas of coverage, the W5IAS linked repeater system serves both as a communications system and a community service. Covering some 50,000 square miles from I-35 to deep into Arkansas and from Texas in the South to Kansas in the North. During times of disasters and other emergencies the W5IAS repeater system will be used for relaying information from one area to another. Several times in the past this impressive system has played major roles in the safety of our communities. Everything from severe weather to the phone outage of the year 2000, which was covered by the TARC and the link system was used to cover the area hospitals. Thirty minutes after the phones went down the TARC was there with a net organized, hours before the EOC and others in the area even knew the phones were out. The TARC is very proud of this system and is always ready to help out in those times of trouble when we are needed the most. The W5IAS linked repeater system is still growing more impressive by the day and is always ready to leap into action.
