Field Day for OVARC is also coming up on June 22-23, 2013. Look at "Field Day" for more information. Read Field Day News #6 to learn about Field Day Tactics.
The Golder Ranch Repeater on 440.400 is off-line being upgraded. Check back here or look for a Groupspaces email to the OVARC membership announcing when it is back on-line.
Gary, KT7AZ, is working on some upgrades to our repeaters system. Once completed the audio performance of the Golder Ranch 440.400 repeater should be corrected and maintenance of the system will become easier. Look forward to more announcements here on the website, on the Sunday night net, and our monthly meetings.

OVARC will participate in ARRL Field Day on June 22-23.
For those unfamiliar with radio contests, I will describe the two basic techniques for operating.
RUN stations stay on one frequency calling CQ and working stations who respond. Typically, stations with big signals will run for hours on end. Stations with peanut whistle signals will be unable to hold a frequency for calling CQ, thus will not be running.
SEARCH & POUNCE (S&P) is the technique of tuning systematically up or down the band working CQing (RUN) stations which are not yet in the log. Stations lacking big signals typically spend most of their time doing S&P, but all stations use this technique at some times during a contest, especially when RUNning is not productive.
N1MM Logger provides for both RUN and S&P techniques. The HELP files in the program elaborate on them.
The first part of the FD exchange is the station class, which consists of a number (corresponding to the number of transmitters in simultaneous use) and a letter, A through F. Letter designations are described in details on the ARRL website. OVARC will be class 3F, meaning 3 transmitters operating from an EOC.
While Field Day is a simple contest, copying the exchange requires some familiarity with the ARRL Section and its abbreviation, which is the second part of the FD exchange. You can find the list at: http://www.arrl.org/section-abbreviations
The complete printed list will be available at each operating position during FD. Note that while some sections are the same as their US state, such as AZ for Arizona, other states have more than one section. California has 10 separate sections! The section, not the state or province, is what must be logged for a legitimate contact. The logging software will reject abbreviations other than those on the list, as will the sponsor of the contest (ARRL)
One more time: there is a terrific instructional video detailing how to use the logging software that we will be using. Program is called N1MM Logger, and link is:
If you plan to operate a FD station, PLEASE view this video!

Amateur Radio and High Altitude Balloon Launches
Professor David Iadevaia, KF7MZY
Prof. Iadevaia will speak on the importance of Ham Radio in high altitude balloon launch, tracking and recovery. The high altitude balloon activity is part of NASA Space Grant program which sponsors high altitude balloon programs at the colleges and universities in Arizona.
Some topics he will cover from an actual flight:
Cross Band repeater
How to get involved
ANSR (Arizona Near Space Research)
Video from 87,000 feet over Picacho Peak
Here is an example of an actual photo taken from the balloon:
