More About Bits and Baud

The 10-meter band offers something for hams of every license class, including Technicians, who can use voice, Morse code, and digital modes on this band. Scott Freeberg, WA9WFA, joins this episode of the podcast to take us on “A Tour of 10 Meters,” and to explain why right now is the best time to get on the band, thanks to the terrific radio wave propagation being generated by Solar Cycle 25. 

The podcast takes a field trip to W1AW, ARRL’s Hiram Percy Maxim Memorial Station, to hear from W1AW Station Manager Joe Carcia, NJ1Q, about all the ways to “Practice Code with W1AW,” from daily code practice sessions at a speed that suits you, to Qualifying Runs where you can earn certificates for submitting accurate copy.

ARRL Director of Emergency Management Josh Johnston, KE5MHV, joins the podcast to share details about ARRL's updated Emergency Communication courses, which have been broken into three successive levels – Basic, Intermediate, and Advanced. The courses are available free of charge at the ARRL Learning Center.

ARRL Radiosport and Regulatory Information Manager Bart Jahnke, W9JJ, and ARRL Contest Program Manager Paul Bourque, N1SFE, join the June episode of the podcast to spread the excitement about ARRL Field Day, which is coming up on June 22 - 23.

This year’s Dayton Hamvention, coming up May 17-19 in Xenia, Ohio, will be extra special — it’s also the 2024 ARRL National Convention. ARRL Director of Marketing & Innovation Bob Inderbitzen, NQ1R, joins this month’s podcast to share details about ARRL-sponsored activities at the show, including several of the ARRL-sponsored forums and the Youth Rally.

We often hear about served agencies when hams talk about disaster response and emergency communications. ARRL Director of Emergency Management Josh Johnston, KE5MHV, joins the podcast this month to discuss exactly what and who served agencies are, and where the Amateur Radio Service fits into their responses.

The Solar Eclipse QSO Party (or SEQP), is an on-air event coming up on April 8, the same day as the next total solar eclipse. The SEQP is a great opportunity for hams to contribute data to studies of Earth’s ionosphere, the part of our atmosphere that makes radio communications possible, and all you have to do is get on the air and operate as you normally would. The lead organizer of HamSCI, Dr. Nathaniel Frissell, W2NAF, joins us in this episode to explain how to get involved.

The January/February 2024 issue of On the Air featured a story from Brian McSpadden Gardener, KE8JVX, about “The First-Year Experiences of a General-Class Ham,” in which Brian detailed how he got his feet wet as a General, and how he put together his first station for HF. Brian joins this episode of the podcast to tell us a little more about his first year as a General, as well as what he’s done since then.

Maintaining a “junk box” — a collection of odds and ends that can be used in future projects and repairs — is a time-honored practice among hams. Every ham radio junk box has to start somewhere, though. The cover story of the January/February 2024 issue of On the Air, “A Fine Mess: Starting Your Junk Box,” by Eric P. Nichols, KL7AJ, offers advice about how to do just that. The January 2024 episode of the On the Air podcast digs deeper by going on location to the workshop of W1AW, ARRL’s Hiram Percy Maxim Memorial Station. Station Manager Joe Carcia, NJ1Q, welcomes us into this working space to show us some real-life junk boxes and discuss how they come in handy. Check out the VIDEO edition of this episode:Starting Your Junk Box (youtube.com)

This episode ties into a feature in the November/December issue called “Bits and Baud,” which discussed important elements of digital communication, namely the quantity of information a transmission delivers -- known as bit rate -- and the rate of speed at which the information is delivered, which is known as baud rate. The article’s author, former QST Editor Steve Ford, WB8IMY, joins us to explain more about the differences between bit rate and baud rate, as well as why hams are concerned with these measurements in the first place.
