Becky KD9FZN First Antenna & Ham Shack Installation

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

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.
"Space Weather" Presentation - Noel Petit WBØVGI

April 9, 2016 - What is it? It's a Magnetometer of course! This instrument was on display during the program presented by Noel WBØVGI at the April club meeting. Through a research grant from the National Science Foundation, Noel was instrumental in the MACCS (Magnetometer Array for Cusp and Cleft Studies) project implementation and post processing of data. Amateur radio operators enjoy the results of this data combined with other observations of space weather and it's affects on the layers of our earth's atmosphere relating to radio propagation.
WBØVGI Space Weather
April 9, 2016 - Noel WBØVGI prepared and delivered an excellent presentation on space weather during the April PCARA club meeting. The effects of the suns' energy and how it relates to the magnetosphere and radio propagation is a topic Noel is well versed in. He teaches computer science at Augsburg College in Minneapolis and is instrumental in the measurement of space weather around the globe. Noel and his team of scientists and students provide data which is compiled into the K-index used by hams as a forecasting element of MUF.
Kit Building Fun!

March 12, 2016 - Solder smoke! Is there anything so enjoyable to a ham radio kit builder? Rick W9WS inspects his work as he assembles a battery voltage monitor kit. The members brought in their soldering stations, tools, magnifying lenses and lighting to participate in the March 2016 kit building portion of the club meeting. The cost of the kits were under $20/ea with most of them around $10. In an hour the members had their kits built and tested.

March 12, 2016 - Mark W9GWG, Greg N9CHA and Wayne KC9RBL joined in the fun of putting together various electronic kits. Mark assembled a code practice oscillator while Wayne tried his hand at an electronic clock kit.
Bill K9WEN kit building
March 12, 2016 - Bill K9WEN examines each component prior to installation. He selected a clock kit that allows you to program the current time, set an alarm, and display a countdown. Each of the members brought different experience levels to the exercise. Everyone had a great time.
