April 4th 2015 RaDAR Challenge: Define your Journey!


1. Aim
The RaDAR “Challenge” is a unique event aimed at promoting the use of Rapidly Deployable Amateur Radio stations. This challenge is for all licensed radio amateurs not limited to South Africa. A RaDAR operator can take part in any of the three defined categories (see point 7) which may be changed at any time during the challenge. The
points system is so structured as to encourage portable RaDAR operations, especially moveable RaDAR stations. Moveable RaDAR stations rely on fixed and portable stations as a point of contact using channelised frequencies. “Search and pounce” techniques are also allowed.

2. Date and Time
From 00:00 UTC to 23:59 UTC on Saturday 4 April 2015 and from 00:00 UTC to 23:59 UTC on Saturday 7 November 2015 - 24 hours will give equal opportunity to the international community of RaDAR operators. RaDAR operators can define their own operating time schedule or remain active for the full 24 hours.

3. Bands and Modes
All amateur bands are allowed including cross band contacts via amateur radio satellites.
Modes – CW, SSB, AM, FM or any legal digital mode. QSOs via terrestrial repeaters will NOT be allowed.

4. Suggested HF calling frequencies
See http://zs6bne.wordpress.com/2013/03/06/radar-calling-frequencies/ for the latest international list of frequencies. The WARC bands can be used considering this is a RaDAR Challenge and not a contest as such. It provides better opportunities for RaDAR contacts during difficult propagation conditions. Recommended digital modes frequencies – Refer to the South African Radio League Contest Manual, General Rule 15.

5. Exchange
The RaDAR challenge requires more than a minimalistic information exchange. Accurate information exchange is considered more important than a large QSO count.
Call sign, name, RS(T) report, QTH and grid locator. Note the grid locator can change as RaDAR operators are allowed to move position at any time. The grid locator of six characters is acceptable but should preferably be accurate to 10 characters for higher
position accuracy. Smartphone applications are generally used to establish more than a 6-character grid locator. If working non-participating stations, call sign, name, RST and QTH is acceptable.

6. Scoring
1 point per QSO.
Individual QSOs – per mode, per band, per satellite, per call sign.
If the moving RaDAR station has moved the required distance (see point 7) contact can be made with a previously worked station, again.

7. Categories and multipliers
The following multipliers are applicable to determine the final score. If category/mode of transport changes were made during the challenge, than calculate accordingly.

X 1 – RaDAR Fixed station (At home or in another building)
X 2 – RaDAR Field station (Portable – away from home)
X 3 – Moving RaDAR station – See modes of transport below.

Modes of transport and required movement distances (moving RaDAR stations only)
Vehicles, motorcycles and motorboats etc. (Motorised transport) – 6 km
Bicycles – 2 km
On foot and paddle canoes – 1 km
Wheelchairs – 500 m
Aeronautical mobile stations are considered moving stations and can communicate at any convenient time.
Note: Moving RaDAR stations can move at any time but are required to move to the next destination after five contacts have been made from the present location. The move needs to cover the required distance before further contacts are allowed to be made. This requirement tests the ability to rapidly re-deploy your amateur radio field station.

9. Bonus points (All categories)
Five (5) points (The equivalent of five QSOs) for a minimum of one satellite or any digital modes QSO involving a computer, smartphone or digital modes device. (For clarity thereafter 1 point per Satellite / Digital modes QSO).
Five (5) points for the first successful same continent RaDAR to RaDAR QSO (As may be confirmed by the extensive information exchange.
Five (5) points for the first intercontinental (DX) QSO
Ten (10) points for the first successful inter continental (DX) RaDAR to RaDAR QSO (As may be confirmed by the extensive information exchange).

10. Log Sheets
Log sheets must be submitted by 14 April 2015 and 17 November 2015 and sent by e-mail to edleighton@gmail.com.

See https://zs6bne.files.wordpress.com/2015/03/11046905_10152762072212759_727315224761083499_n.jpg for a log sheet specifically designed for the 2015 RaDAR contest.
Note: A photo of the station (JPG format) MUST accompany every log entry. A photo is required for each new location that moveable stations visit. These photos are used to promote amateur radio and the RaDAR concept showing where amateur radio can be used to communicate from and in the many different ways.

RaDAR Challenge: Have it Your Way!

The previous Rapid Deployment Amateur Radio (RaDAR) Contests were four hour events on the first Saturday of April and November. The contests were a specific four hour time slot which worked for me and I did enjoy working against the clock. However, for operators all around the globe a specific time slot does not work. Eddie ZS6BNE has evolved the RaDAR contest into the RaDAR Challenge which will be a 24 hour event on the same days. That will to give us the maximum flexibility to schedule our operations. Likewise RaDAR is about motion. Make five contacts and move! How you move is up to you. I will let the graphics below tell the story. Funny, I had thought about doing RaDAR ops for Field Day. Moving during Field day is non-traditional but not precluded by the rules. Now with the RaDAR Challenge being 24 hours I can have a Field day RaDAR style in April. I really would like to hit all my favorite spots in one day. Of course now the challenge is getting April 4th set aside.




If this idea appeals to you visit Eddie's Blog and the Google+ RaDAR Community.

Follow up on the QSO Today Podcast

In the podcast for QSO Today with Eric Guth I could not remember my "Elmer" Doug Snellgrove of Dothan's call from my Novice days in the late 60s. My Dad worked with Doug at the Post Office and my Dad went to Doug to get me started in ham radio. Doug gave me the Novice test and loaned me a HT-6 transmitter for my Novice station. My novice call was WN4JFW. When Forrest WB4SVX back then and now N4FRQ living in Mobile Alabama, heard the podcast he noted that Doug's call was K4DR. A google search brought up his QSL on a site of antique QSLs. Further searches came up with the info below.  Doug's other hobby was photography. I note there is a Doug Snellgrove Memorial B&W Photography Award given each year at the Dothan Peanut Festival.



Birth: 
Apr. 4, 1919
Chancellor
Geneva County
Alabama, USA
Death: 
Sep. 7, 1990

Parents Thomas Abraham Snellgrove and Eula Stokes.

Information from the Wiregrass Archives in Dothan: (submited by Rachel Dobson)Joseph Douglas "Doug" Snellgrove was a semi-professional photographer who created a visual record of SE Alabama and SW Georgia in the 1960's through 1980's. He was particularly interested in color photography of flowers and black-and-white photography of rural lifeways. He made many photographs of rural tourist attractions, such as Westville in Georgia and Landmark Park near Dothan. Mr.Snellgrove was a World War II Army veteran, and worked for the US Postal Service from 1958 until his retirement in 1978. Born in Chancellor, Alabama, Snellgrove was a lifelong resident of Dothan, alabama, and a member of the Cloverdale United Methodist Church.
The "D. Snellgrove Collection" of his photographs is in the Wiregrass Archives at Troy University, Dothan Campus.

QSO Today with Greg, N4KGL

I had the honor of doing a QSO Today Podcast with Eric Guth 4Z1UG. Eric has quite a impressive list of podcasts with hams. Some you may know and others you would not. But they all have a great personal stories. Eric combines great interview skills with his technical skills to do the podcast. My podcast covers more than ham radio and you will hear how it all ties together. All this reminds me how blessed I am to have the support of my wife, parents and friends. Thanks Eric and everyone enjoy the rag chew!

N4KGL RaDAR Meetup Ops for February 2015

Saturday, February 7th, was the Monthly On-The-Air Meetup for the RaDAR community. I was not too ambitious on a location. I chose my front yard since I needed to help out with Suzy our basset puppy. As the bands included 40 and 15 meters I decided on a 40 meter dipole. The 40 meter dipole covers 15 on the third harmonic. I also paralleled a 20 meter dipole on the same coax. This makes quite a yard display. I used a tripod structure made from "camo" poles to hold up the center and fiberglass poles for the four dipole ends. The center being only about 24 feet up I would say it qualifies as a Near Vertical Incident Skywave NVIS antenna on 40 meters.

Greg N4KGL's setup in his front yard.
Center pole for the dipoles. Note there is a rollup 2 meter slim-jim antenna at the top.
A 28 watt solar panel just for fun. It topped off the battery so it was putting in more than I was using.
My first QSO was actually line of sight to my neighbor K4GXV Vic at the end of my street. My next CQ yielded a call from KK4SGF in Albany Georgia which is 130 miles away. I'd say that was NVIS. Then, I found Tom G0SWB warming up the 21.350 15 meters frequency. Tom was Pedestrian Mobile. He was between S3 and S6 with fairly good copy. We exchanged grid squares. His was JO01MS49GV. I believe he was running 20 watts and I was running 12 watts. It is a joy to work a /PM DX station. Below is a selfie video of Tom's Pedestrian Mobile gear. Warning it might be scary for small children.


I jumped back to 40 CW and ran across AK4JA Bobby in Newnan, Georgia. This was fun because I have worked Bobby several times including 60 meters. I also met Bobby for breakfast when he was in Panama City a while back. We exchanged SKCC numbers. Bobby is one to watch for as he often runs QRPp. Fred VE3FAL was monitoring the meetup on Google+. The -21C wind chill in Thunder Bay, Ontario would not allow an outing there. But never the less Fred suited up with his PRC 104 radio and stepped outside into the weather.  We pulled off a QSO back on 21.357 15 meters. His grid square was EN58HH.


Note Fred worked KK4QAM Don in Alabama at the end of the video. Don is another RaDAR op and he setup a homemade Buddistick for the meetup.

My last QSO was with Mike VE3EDX on 21.063. He sent Grrrrr which is a good sign he was a Polar Bear op. You never know who you will run into. Well it was not in the cards to redeploy and my setup was fairly heavy with the camo poles. I have had good success with the 40/20 dipole combo. It is handy if you can pull it up with a tree limb. I did that for my SOTA outing.

Eddie ZS6BNE was doing a mountain RaDAR adventure in South Africa that started well before the RaDAR meetup. Details to follow he says. I like this photo from the outing he shared.

Eddie is the originator of the Shack In a Sack concept in South Africa. This later became known as Rapid Deployment Amateur Radio or RaDAR. Eddie's life adventure in Amateur Radio is the subject of a recent podcast on QSO Today with Eric Guth.

So this was my take on the RaDAR meeting. Not a lot of QSOs but it is hard to beat working my friends doing RaDAR pedestrian mobile. The last photo is Suzy a RaDAR beginner.

Rockets, RaDAR, Philco and Puppy Weekend

This weekend was a Samson Alabama rocket launch. Bob KK4DIV from Lynn Haven, Florida attended a launch for the first time. My first rocket launch was a 3 inch diameter payload rocket with a two meter fox on-board. Although it was in-sight all the way, we used the opportunity to do some tracking. Bob used a tape measure antenna and I used an Elk antenna.

My second launch was a rocket having an unusual shape. It is the Stealth 54 Rocket from Art Applewhite. It consist of foam board covered by fiberglass. It does not go very high due to the large amount of drag. Never the less with a K motor the trip up is pretty spectacular. The trip down does not require a parachute as the drag slows it down.

Bob and I setup on the field for Rapid Deployment Amateur Radio (RaDAR) ops. Bob worked Puerto Rico and Brazil on 10 meters. That was pretty good with his FT 817 on internal battery and a MFJ 1889T antenna.

I set up with the Alexloop and the KX3. I worked a station in the Azores on 17 meters SSB.

 Micky and John W8JER also joined us to watch rockets and talk radios.

While in Dothan on Sunday, Tom WD0HBR and I continued troubleshooting the 1930 Philco. It had a loud hum in the speaker. However with a short antenna and tuning around it picked up a local gospel program from WOOF in Dothan. the station overcomes the hum to some extent. It was quite exciting and surprising that the radio worked. We thought there were more serious issues, but it basically only needed the power switch cleaned to get it going. Thanks Tom for the help with this radio!

Linda and I have a new puppy named Suzy. She is a eight week old basset. We picked her up in Gainesville, Florida FL on Friday. She is very sweet and oh yes and cute.

How Sweet It Is By the Saltwater

On the MLK Holiday, I signed up to operate as K3Y/4 for two hours in the morning. K3Y stations are special event for the Straight Key Century Club Anniversary. With the nice weather, I decided to operate portable at St Andrews State Park near Panama City, Florida. As QRP is not encouraged for K3Y I took the Icom 7100 for QRO. I chose 15 meters and picked a spot with a picnic table right on Grand Lagoon. I deployed the N6BT Bravo 7K right on the water. I kept busy for the two hours with twenty five CW contacts. Two were DX, France and Czechoslovakia.




After some lunch, I decided to proceed to Sandy Point at the Northeast end of the park. I had to lighten up so I took the KX3. I still decided to continue with the Bravo 7K. At twelve pounds not so light, but I discovered I could put it on my shoulder and do pretty well. I setup after the one kilometre walk. I really enjoy the boat and yacht traffic in the channel. I also discovered a rather large bird was listening in. I made seven contacts on 17 meters. Several were very long as I got quizzed on the KX3 and the Bravo 7K. The Bravo 7K lived up to expectations for the day. When the wake of the larger boats came in the waves crashed on the tripod. I held the frequency rather well using the Bravo 7K near the saltwater. I got some good reports for using 10 watts. Having nice weather, a beautiful location and ham radio come together on my day off is awesome! Enjoy the photos.
