QSL?

Presented by Tom W8TK

The Q-code was developed decades ago to make communication via Morse code more efficient. It was the predecessor of the abbreviations used today for texting. QSL means “I acknowledge receipt” and with a question mark added, QSL? means “Do you acknowledge receipt?” Over the years, QSL has come to mean a written or electronic confirmation of a contact (Q-code for contact = QSO) made over the air. Tom, W8TK, will describe the tradition of exchanging QSL cards and reasons for doing so, with numerous examples of cards from his collection. He will also discuss design, printing, mailing of cards, QSL bureaus, and modern electronic QSL methods.

W8TK has been continuously licensed since 1959 and has exchanged thousands of paper cards over the years as well as uploading over a half million contacts to Logbook of the World.

Navigation and GPS

Presented by George NG7A

  Figuring out one’s location and how to get to a destination may be one of mankind’s oldest pastimes. Navigation and positioning are crucial to many activities and yet have been quite cumbersome. Over time, all kinds of technologies have attempted to simplify the task, but each one has had a major disadvantage. When the US DoD decided to have a super precise form of worldwide positioning, they had the kind of money ($12 Billion) to build something really good.

Our own George NG7A will briefly examine the historical forms of Navigation and then delve into the inner workings of GPS. He led the RF design team at UPS Aviation Technologies that developed the World’s First GPS Receiver certified by the Federal Aviation Administration to provide vertical guidance through the clouds to within 200 feet of the ground. Some practical tips on best operating practices of GPS and how to minimize jamming from other radios will be offered.

Software Defined Radios

Presented by Stephen Hicks, N5AC

  

Is Software Defined Radio (SDR) the future of ham radio?
What makes an SDR different from a classic radio?
Would an SDR make my radio use better and more fun?
Can I work more stations in a contest with an SDR?
Is SDR just an architectural difference in the "guts" of the radio or is it more?
Can I get an SDR with knobs?

Steve will discuss the genesis of Software Define Radio (SDR) and its debut in ham radio. He will cover the different elements of an SDR in an easy-to-understand way and provide you with a working knowledge of the different kinds of SDRs and the benefits of these differences. He will then talk about how an SDR can provide benefits in different operating modes and the tradeoffs that have been made in the production of different SDRs. An overview of FlexRadios products and some other SDRs will be provided including a look at Maestro, FlexRadio Systems' new breakout device that is changing the way hams look at SDR. At the conclusion of the talk, Steve will answer your questions about radios and how they work.
