August 6, 2016 - Mounted to the west leg of the tower where the club's N9XH repeater and APRS systems are located, is a new internet subscriber module. Located at 120' the module points towards the Polk County Government building where the access point had been installed the week before.
Tower climb
August 6, 2016 - Project manager Rick W9RGS asked his friend Mike if he would climb the tower and install the module. Once fastened to the tower, a shielded CAT5e cable was laced down and secured. The module receives its power from the cable as well as transporting data.
Subscriber unit install
August 6, 2016 - Mike secured the cable to the tower leg as he descended. He is perched just above the UHF beam pointed toward Taylors Falls as a part of the remote link serving the St. Croix River gorge in Polk County.
W9RGS drone
August 6, 2016 - A camera drone was used during the installation to document the process. It also provided a great reference point for height. Rick W9RGS, drone pilot and project manager, was able to tell Mike how high above the ground the drone was, which in turn indicated the expected height the subscriber module needed to be mounted.

Peppa Pig Journey to Near-Space
Hidden Oaks Middle School - PeppaSpace
May 27, 2016 - The StarTribune reported a nice story about the Hidden Oaks Middle School high altitude balloon flight which took place on May 24th. The data collected during the flight indicated the balloon rose to over 85,000 feet - 16 miles - surpassing the goal of 80,000 feet. A low temperature of -40 degrees and a maximum speed of 117 miles per hour were also recorded.
Hidden Oaks Middle School - PeppawithSchool
May 27, 2016 - Peppa Pig is now an experienced traveler. Three-hundred middle schoolers watched as two high altitude balloon's payload tracked their path, captured photographs and collected data on temperature, altitude and air pressure so students could analyze it in science class. APRS tracking transmitters were attached to both flights, KC9ROI-11 and N9CHA-11. "It's one of the rare opportunities for [students] to get real data," said Becky Stark, science teacher. "We had perfect weather." (StarTribune)

Introduction to Amateur Radio - Chris KC9NVV
KC9NVV Valley Christian School Presentation
May 10, 2016 - Chris KC9NVV, club Treasurer and ARES/RACES DEC presented a program introducing amateur radio to students at Valley Christian School, Osceola. Chris answered questions about the hobby including a thoughtful query from a young man who asked, "What do the astronauts eat aboard the International Space Station?" A lively demonstration of radio teletype, Morse code, and voice were also presented. With an antenna set up outside the classroom, Chris, and assistant Greg N9CHA had some of the kids talk through the N9XH repeater to Becky KD9FZN. Favorite colors, pet names, and what classes were most enjoyable filled out the conversations. After the presentation, several students asked for more information!
 
K9WEN Tower Project - Just Add Water (Cement)
K9WEN Tower Base
May 7, 2016 - One of the most important steps in putting up a tower is proper planning, good quality materials, and strong engineering. Bill K9WEN has taken the time necessary to plan and construct a heavy steel tilt plate for his 40' tower project. Osceola is a challenge when it comes to digging a hole. Glacial deposits including trap rock is very hard to dig and requires lots of patience and plenty of strength. Next step, add the cement!
 
Becky KD9FZN First Antenna & Ham Shack Installation
KD9FZN Antenna Mast
Photo: Becky KD9FZN

April 23, 2016 - One of our newest members, and a recently licensed ham, Beck KD9FZN, installed an antenna mast to her home on Saturday. The 2" aluminum mast is 20' tall, with a 4' fiberglass mast mounted on top. At the very top is a Diamond X50 VHF/UHF vertical antenna.

Becky and her husband Jon mounted the mast to the gable end of their home using lumber tied into the facia. U-Bolts fasten the mast to the roof. At the base they dug out a portion of dirt to accommodate a patio tile and a aluminum car wheel to act as the lower support. Once backfilled the bottom portion of the mast is securely in place. An 8' ground rod was installed as well.

At about the 6' point on the mast is an Icom AH-4 auto tuner which will feed a 150' length of wire supported by two nearby trees. This end fed antenna will be cable of 80 - 10 meter operation.

Coax cables include a 65' length of LMR-400 used for the VHF/UHF antenna. Another 65' length of Belden 8214 for the HF station, and a 65' length of multi-conductor shielded control cable which attaches between the rig and the tuner.

Becky has a first-class ham shack too. She is using the Yaesu FT-8800 for both VHF and UHF FM communications. On HF she has an Icom 756Pro. Both rigs are powered by a 30 amp linear power supply and Rig Runner. Digital modes are supported using a Signal Link interface and a laptop computer.

Look for Becky on the air! She listens regularly to the N9XH repeaters.

 
Looks Like New! - KD6TWC's SB-221
SB-221 2KW Linear Amp
Photo: Rick W9WS
April 16, 2016 - The Heathkit SB-221 2KW linear amplifier... owned by Robert KD6TWC and brought back to life by Rick W9WS. Utilizing 2 3-500Z tubes, this 80-15 meter amp can produce 1200 watts from a 100 watt exciter. Wired for either 120vac or 240vac, this 1976 model unit is not as popular as its predecessor, the SB-220. The only difference was the elimination of the 10 meter band on the SB-221. However, licensed amateurs could purchase the parts needed at time of assembly to accommodate the higher frequencies. Robert's model has a new black front panel rather than the typical green one which was provided to the original owner. The sleek, black panel gives the amp a commanding look and will be a much-treasured addition to his ham shack.

February 20, 2016 - Once again this year, the American Birkebeiner ski race was supported by ham radio volunteers, including many from the PCARA. Radio communications from the various checkpoints and aid stations is a vital part of keeping the race officials aware of conditions during the Cable to Hayward event. PCARA volunteers: Chris KC9NVV, Rick W9WS and wife Paula, Paul KB9TYC, Tom AC9LG, Duana KC9UVK, Dale W9DKB, William N9DIW and Greg N9CHA.
Birkie 2016 ski race
February 20, 2016 - Of the 10,500 skiing participants, only a few could not make the entire journey down the course. When a skier dropped out, the ham radio operator at the aid station took down the bib number and recorded the reason as an equipment failure, medical reason, or fatigue. This information was then relayed to net control where the data was logged into a database system being monitored by race officials.
Birkie 2016 Volunteers

February 20, 2016 - Volunteers from all walks of life, from all areas surrounding the Northern Wisconsin event make the Birkie possible. Handing out water, food, energy drinks and supplements, clearing the trail of debris, parking, hauling supplies, and many other tasks are cheerfully accomplished by people who want to support the event. Wally N9VAO, EC Sawyer County and Chris KC9NVV DEC NW WI have been working together for months recruiting and planning the ham radio component of the race. John N9UPC set up a new repeater in Hayward as well as a cross-band link to provide course-wide coverage.
OO Tipper
February 20, 2016 - At the support station set up at "OO" Greg N9CHA and William N9DIW implemented a 20" antenna mast system. The base of the "tipper" is positioned under the van wheel and the mast is put together and tipped up into place. The antenna was used to cross-band the signals since a 5 watt hand held was not efficient enough to communicate directly.
OO tipper mast
February 20, 2016 - The "tipper" antenna mast can be seen in the center of the photo, blending in with the surrounding trees. An FT-8800 was programmed for use, running 10 watts out to the VHF repeater near Hayward, and 5 watts on UHF to the local hand helds. Power was supplied by a deep cycle battery and voltage regulator.
