I enjoy Rapid Deployment Amateur Radio, Field Days, QRP, satellites, and CW. I have many friends in the hobby that make it fun. I will keep you posted on what I learn about amateur radio on this blog.
Today was the Second Second Saturday Sprint for June. The SSS is sponsored by the Google+ QRP Field Ops Community and runs from May through October. I decided to deploy the Field Day Loop in the front yard. I got out early and set it up. I captured the setup on video. I also used an ArtCraft AH4 Interface box successfully with the Icom AH-4. This allows me to initiate tuning of the AH-4 from the Elecraft KX2.
I took on a challenge today I chose to operate QRP. I also decided to feed the loop from the bottom corner for vertical polarization. I knew that was not the best idea for 40 meters. It was OK on 20 meters. It is preferred on 15 meters for the loop, but no signals heard on 15.

I started on 40 CW and was glad to hear my friend Don KK4QAM in Sweetwater, Alabama. This was followed by local contacts with Mike KM4ELJ, Bob KK4DIV, and Don KK4DWC. Bob KK4DIV was set up at Under The Oaks Park about 12 miles away. Next was 20 CW, I had four SKCC contacts and one casual contact. I went to 2 meters and worked KK4DWC Don, N1HQ Jack, N4FA Charlie all on simplex. I rounded the two hours out with Jack N1HQ on 20 SSB. He lives on my street. I was pleased to work N9XG doing SOTA on 40 CW and KJ4UHR on 40 SSB in Kentucky. It felt like the bands were weak, but I can't complain about a page of contacts.

I will go back to feeding the loop at the bottom center for Field Day. But, I had to give the bottom corner feed a try. I will be setting up at Falling Waters State Park on Friday afternoon, June 23rd with the same antenna. That evening will be QRP Night. So basically I will be ready ahead of time. I can do some contacts for Parks On The Air Saturday morning. I will kick off Field Day using the call N4Y and category 1A. at 1800 UTC Saturday.
I did my first overnight camping trip at Falling Waters State Park Florida. This was a POTA activation for KFF-1864 and a dry run for Field Day 2017. I was at campsite 11 which will be the same campsite for Field Day. I was glad to see that the loop antenna fit well. I placed it in in the center of the pull-in area. It did get the interest up of the neighboring campers. They came by for a chat and said they were quite impressed with the push-up process. Of course, they did not know what it was for until they asked. Doug my immediate campsite neighbor is going to put photos of the antenna on his travel blog. He and his wife Barbara travel in an A-shaped camping trailer. Doug says Linda and I could have lots of fun camping.
I had a mix of contacts including working my friends in Panama City, POTA chasers, and museum ships. A highlight was working EA8ARI at EAFF-0079. This qualifies for WWFF Park to Park awards. I also worked KH6ZM in Hawaii on 40 meters CW. I had 56 contacts total. The antenna performed well for US and DX.

I slept in the tent-cot I brought. It is an easy setup. Thanks to Rick NZ2I for the idea. The one test I did not get was enduring a downpour. It thinks it would disrupt operating. We will see what Field Day brings. I am real confident I have the right piece parts gathered. The Icom 7300 was a joy to operate. I will operate Field Day with a few friends. The callsign will be N4Y. I am ready to go.
Saturday, I set up the Field Day loop antenna again in the front yard. This was an opportunity to test the antenna with the Icom AH-4 tuner. While I was there, I substantially pulled together much the gear I would use in Field Day. This included the Icom IC-7300, battery, my solar panel and the 10 ft by 10 ft canopy and so forth. It is helpful to see and use them together. It helps build confidence that my pack up will be complete. The video below gives the tour. I only made a few contacts on 40 and 20, but I am feeling good about the loop. I did have a good QSO with Tom WD0HBR in Dothan on 40 meters. The loop tuned well on 40 through 10 meters. So I am going to stick with the Icom AH-4 tuner.
My location for Field day this year is Falling Waters State Park in Chipley, Florida. I have reserved the same campsite I will use for Field Day for this Friday night, June 2nd as a pre-Field Day test. I can get the feel on how my gear and the antenna will fit. Who knows I might get new ideas or discover adjustments. It also will be an opportunity to activate Falling Waters for the Parks On The Air Program WWFF-KFF. The park is reference KFF-1864. Here is the announcement:
KFF-1864 Activation by N4KGL
From: Saturday, June 3rd 2017, 12:00 am UTC
To: Saturday, June 3rd 2017, 4:00 pm UTC
I plan to camp out and activate KFF-1864 Falling Waters State Park in Northwest Florida. I will operate mostly 40 and 20 meters using CW and SSB. This is a warm up for ARRL Field Day as I will use the same site for that event. I will spot on DX Cluster see http://wwff.co/dx-cluster/ See WWFF-KFF Parks On The Air details at https://wwff-kff.com/ I should be in the range of the AC4QB 145.330 repeater. Chasers welcome. I submit the logs to WWFF and you automatically get credit.

Note: Field Day is June 24-25, 2017. I will be using callsign N4Y. My category is 1A, and the section is Northern Florida NFL.
On Sunday afternoon I spent some more time on my Field Day Loop. I measured it out and put the insulators at the right places. I also setup a feed point at the bottom center and the bottom corner. I made a 300-ohm jumper to the AH-4 tuner.I have not tested it with the AH-4 yet. Thanks to Myron WV0H for help with analysis of this antenna. This is a 100 ft wire loop 30 ft across by 20 ft high. The bottom wire is 10 ft above the ground. It is NVIS antenna on 40 meters and has 39 deg elevated lobes broadside on 20 meters when fed at the bottom center. It has low angle radiation on 20 through 10 meters when fed a the bottom corner. The three poles are strapped to angle iron driven in 1ft in the ground. The poles allow raising the loop in push-up fashion. It is designed to fit in a camp site without using trees or extending beyond the bounds of the camp site. I can use the Icom AH-4 tuner or a matching transformer with a tuner at the rig. The 300-ohm feedline and the tuner can be switched from bottom center to bottom corner.
The 2017 Second Saturday Sprints sponsored by QRP Field Ops Google Plus Community began on May 14th. These are two hours 1900 UTC to 2100 UTC. See the rules at this link. The goal is to work other members of the group. However, any contacts you make will count. Therefore you can leverage off of other events. This is good practice for RaDAR style ops. I leveraged off of SKCC contacts and Arkansas QSO Party. Likewise I have a cadre of local chasers. They had no problem working me in town on HF. I also made contacts with them on 2 meter simplex.
Note the three poles for the loop antenna.
I setup in the front yard of my house. I wanted to test an antenna configuration for the upcoming Field Day. The antenna is a 30 ft long by 20 ft high loop supported by three 30 ft fiberglass poles. The motivation for the loop is to stay within the confines of the camp site at Falling Waters State Park. I anchored the poles with a length of angle iron. I pound them in the ground about one foot and strap the poles to them. I can attach the wires at the top of the poles and push the poles up. There is no weight at the top other than the wire going across. This is pretty easy to erect. The loop is fed at the bottom center which is about ten feet high. I used a Chameleon 5 to 1 transformer at the feed point and 30 feet of RG-8X to the tuner which is an LDG IT-100. The rig was my Icom 7100 on battery.

For the sprint I started on 40 meters. There was very little activity on the band perhaps due to conditions. I did snag local chasers Rick NZ2I, Bob WB4BLX and Bob KK4DIV. So I don't think I can draw any conclusions about the antenna on 40. I hope on the next test the band is more active. On 20 meters the band was better. I worked six stations out of town with no problem I also got WB4BLX, KK4DIV and Phil N4STC near by. So I will give the loop antenna a passing grade on 20 meters.

Myron WV0H kindly did some analysis on the antenna configuration. The analysis indicated that using larger coax like LM400 would be beneficial to reduce losses. I have many options for feeding and matching the antenna. I may try 300 ohm line as well. Note, I plan to dry run Field Day on June 2nd at the Falling Water Camp site. Then I can custom fit this antenna to the site. Of course I have many antenna options to consider.
Operating from the shade
I am looking forward to future Second Saturday sprints. I hope to work some members next time. I also did some satellite work earlier in the day. I met with Bob KK4DIV and Bob WB4BLX behind the PCARC Club house. I was able to get three on FO29. So I got a good dose of ham radio on Saturday.
I decided to do this year's June 24/25 ARRL Field Day apart from the local club. I have a camp site reserved at Falling Waters State Park near Chipley, Florida just South of I-10. The funny thing is I am not a camper so we will see how that goes. Being new to camping, I better stay out of trouble, Therefore, I plan on keeping my antennas out of the trees and within the limits of the camp site.
For planning purposes lets say I have 30 feet of linear space for an antenna. So I envision a 30 foot long and 20 foot tall vertical loop. I can support that with two 31 foot Jackite poles. The bottom of the loop will be ten feet off the ground and fed at the bottom center with an Icom AH-4 tuner. It seems I have read that in a wooded area horizontal polarization is better. Myron WV0H modeled the loop and says it will be a good NVIS antenna on 40 meters and has a 39 deg lobes broadside on 20 meters. That should do fine for Field Day. Of course, I better try to setup and test this antenna with the tuner before the event.
I have an Icom IC-7300 that gets light use so I am leaning toward using it for the event. I like the spectrum scope to help walk across the bands. I am likely going non QRP but the jury is still out. I will be all non-commercial power using LiFePO4 batteries from Bioenno with solar assist. The site is partial shade.I have a 10 by 10 foot pop up canopy with a bug screen. For sleep, if I get any I have a new tent cot.
I have some buddies that will drop by and possibly operate. I actually reserved the call N4Y November 4 Yankee. Maybe they will bring some food because Suzy and I will get hungry. There are more details to work on. If you are not out on your own for Field Day check in with your local club. Our Panama City ARC will operate from the Bay County EOC.
Sometimes things just work out to your favor. This was the case for my Rapid Deployment Amateur Radio (RaDAR) Challenge outing on Saturday April 1st. I chose St. George Island State Park in Florida. This is a beautiful park with beaches on the South side and bay front access on the North side. The weather was stellar with clear blue skies. Contrast that with Julian OH8STN operating RaDAR in Finland. He endured freezing rain but still had a good time.

I thank Eddie ZS6BNE of South Africa for originating RaDAR. The RaDAR Challenge now occurs the first Saturday of April, the third Saturday of July and the first Saturday of November each year. I have been participating since April 2013. The RaDAR challenge is a 4 hour stress test for your portable equipment and operating skill. In the Challenge, you make five contacts and move to another location. The distances vary by the transportation mode. I was on foot which is requires one kilometer. I chose to use my Icom 7100 for the expected difficult conditions. The battery and rig are heavy but a dog stroller I have made moving the gear very easy.

Eddie was not able to practice RaDAR on foot this year. He recently was bitten on the foot by a large dog while jogging. However, Eddie was operating portable and focusing on RaDAR DX. That influenced me to choose St George Island. I subscribe to the salt water effect. This is that low angle radiation is enhanced for vertically polarized antennas at the shoreline or over saltwater. St George Island has a clear shot toward South Africa over the Gulf.
My first stop was on the beach. I had a schedule prearranged to walk through the bands on CW from 10 meters to 20 meters. I could not hear Eddie. He could hear me but I was too weak to work. However, I did QSO with Eddie's friend John Kramer ZS5J on 15 and 17 meters. I still needed five contacts to move. Then I worked Rubin AC2RJ on 20 meters. I was unaware he was chasing me but that QSO helped get the five. He made a RaDAR video from his end.
On my second stop, I set up my low dipole on forty meters. That enabled me to work chasers close by. That included Mike KM4ELJ near Panama City and Tom WD0HBR in Dothan, Alabama. A pleasant surprise was Craig NM4T The Huntsville QRP Guy. He worked me from his home in Alabama. It just happened that April 1st was the Florida State Parks On The Air Contest sponsored by the Lakeland ARC. I made a string of 16 contacts that counted toward that contest. I worked two other Florida State Parks including K4LKL which was the bonus station for the contest. The operator was a friend Matthew KK4FEM.
I timed my third stop to coincide with a SO 50 pass. Making a satellite pass counts toward a bonus for the RaDAR Challenge. I envisioned getting my five contacts all on the pass. The sat was so busy that I lucky to get one contact. Matthew KK4FEM came through for me. I picked up the remaining four on 20 SSB using the low dipole measured out for the band. This completed the four hours. But there is more.
The World Wide Fauna and Flora program for the USA, WWFF-KFF, has awards for radar. making three transitions in 24 hours qualifies for a Warthog award, four is the Rhino award and six for the Cheetah award. I had enough for the Warthog but one more stop would give me the Rhino. So another one kilometer walk and I got five contacts on 20 CW. Two were WWFF chasers from Croatia. See my Rhino Award here. But there is more.
On the way home, I passed by a small Florida State Park where the Florida Constitution Museum is located. I spent one hour there and got ten contacts. That is enough for a WWFF-KFF activation. I certainly was blessed with a wonderful day to practice RaDAR, the Florida State Parks On the Air and World Wide Fauna and Flora all on the same day.Doing RaDAR you learn to leverage off of other activities going on at the time. Propagation conditions for my ops were better than expected.
I was also pleased that Julian OH8STN, Tom G0SWB, Mickey NY2MC, Scott ND9E, and Rubin AC2RJ among others practiced RaDAR in unique ways. Some others just could not make it out. We all look forward to the July 15th RaDAR Challenge. Of course, it is unbearably hot then in Florida. The tables will be turned.
