Antenna in the Wind
I think many of you might enjoy a funny compare and contrast set of pictures from N1CHS the Chelmsford High School Amateur Radio Club in Chelmsford, Massachusetts. This is the club that my brother and I founded in 2005. Some antenna work was done recently to replace a temporary mast used to hold up a Cushcraft R6000 antenna from the ARRL Big Project Grant in 2006. The antenna has been on a temporary mast since about October 2009. It has since been replaced with a more appropriately sized antenna mast.

Clutter In The Clubroom
Imagine the following scene. Opening the door to the club station you notice the door bumps against something as it swings forward. “Ah! I forgot to move the rusty repeater the club owned in 1982!” you exclaim; at the same time wriggling through the doorway into the room. Flipping on the light switch you take notice of the decades of successful radio, electronics, and other assorted equipment collecting by past and present club members. Congratulations on owning a 12 foot by 8 foot junk box.
Clubs are a collaborative effort. They take years to establish and decades to perfect. Along the way good intentions get the better of us all and university students are not excluded. Ham radio enjoys a large percentage of people who like to build projects; often the projects pertain to radio but this is not always the case. We all have a time where after obtaining someone else's junk, namely your treasure, intended to be put into a project but in the end you get busy and it never gets done. Do this over the course of fifty years and jeez, it adds up!
One of the best ways to correct this is to make it a club event. Club room cleanup days can make monotonous and often laborious tasks fun for everyone. Well, it may not be THAT much fun but its a heck of a lot more enjoyable than doing it alone. It's nice to get permission from the proper authorities (i.e. club advisor, president, etc) to get rid of equipment that is cluttering the club room. First off give members a chance to grab what they want from the dumpster pile. Just do this under the condition that the equipment can't be stored in the club room. We all know where that leads too and it can be counterproductive. Recycle as much as possible and find a dumpster you're allowed to dispose trash from your club into for the rest.

K2GXT clubroom even had three Rhon 25 tower section in the room, they are still there but hung up on the wall as shelves.
Clutter free club rooms are efficient club rooms and as my rowing coach (RIT Crew) always says "A clean boat is a fast boat!" More members can fit into the space and it becomes a showcase for prospective radio amateurs rather than the equivalent of a walk-in closet for junk parts. Winning the award for the messiest shack isn't exactly prestigious! Good luck to all who are affected by messy club rooms, you may just need all luck you can get
Getting Louder at School With Amplifiers and Antennas
One of my recent projects for K2GXT has been to fix a broken Yaesu FL-7000 HF amplifier which K2GXT owns. It spent the summer at my house in Massachusetts where I actually have the time to fix it as opposed to at school where there is little free time. Bill Grassa N4ATS provided helpful information and parts for the amplifier. The power supply transistors had been blown causing the voltage to be too high. This caused the Yaesu FL-7000 to trip its protection circuits whenever the push-to-talk button was keyed; hence, we had an amplifier which was unusable.
Prior to this the RIT amateur radio club ran barefoot which means using only the transceiver with no amplifier. This typically is about 100 watts with most of today's radios. Building an amateur radio station capable of transmitting a strong signal with only 100 watts is an important consideration. A station that is loud with such capabilities means it has an efficient antenna system and location, for the most part. When an amplifier is introduced to the mix, The loud signal heard on the air is that much more effective when the amplifier is used.
This boils down to antennas. There's no sense in using an amplifier with an amateur radio station that radiates power inefficiently. The RIT amateur radio club has such a station on the air. An off center fed dipole (OCFD) was built and installed a year and a half ago. The antenna is also referred to as an off center fed doublet. More information can be found on the L.B. Cebik (SK) Website. The antenna radiates efficiently, often preferred over the high frequency (HF) beam we also own. The Yaesu FL-7000 is going to really pump up the signal of the club with the antenna system installed. If you operated a school club with an ineffective antenna try to fix it before adding an amplifier to the system.
