Tektronix 475 Oscilloscope and Android Signal Generator App

Watching a capacitor charge 250 times a second The lines are a bit wide because the signal source was noisy

Tek 475 Specs

An oscilloscope needs a function generator

Frequency Generator App set to 1 kHz

Square Wave?

Square waves are not

Reduce the time base to zoom in

Yea, square wave.... not so much

The square wave is bad but sine and triangle waves look good until the frequency get's near the top of the range or the amplitude is raised too high.

Sine Waves look good

Triangle waves are on as well until you go up in frequency

The free app is inadequate for bench testing

Only the beginning

I have my opinion on ARRL asking FCC to grant more HF privileges to Technician-class licensees.

I verbalize them in this video:

After you hear my comments, please leave your comments.

The Air Show Experience
By Brian and Jo Marie Topolski KA1VCA

Veteran air show attendees, Brian and Jo Marie, recount the various aerial acts they saw during last year’s air show schedule, including some they had never seen before, and they let you know what frequencies they were monitoring along the way. You’ll also get tips on attending air shows near you—when to arrive, what to bring, what not to bring, where to set up for the best view and why you shouldn’t leave early.

Air Show 2017:
My Flight in a B24 Liberator and Flying with the Geico Skytypers
By Kevin Burke

Over the years, as a veteran air show attendee with media credentials, Kevin has found himself in the air in some amazing air show aircraft. Last year he had the chance to fly in a WWII-era B24 Liberator as well as the chance to fly in a WWII-era Navy SNJ-2 trainer with the Geico Skytypers, both of which gave him unforgettable rides. He gives us some terrific photos he took of the vintage aircraft he saw.

TSM Guide to Monitoring Air Shows
By Larry Van Horn N5FPW

Anyone who has attended an air show will tell you it is thrilling to watch the close quarter flying of the Blue Angels delta formation or the hair-splitting maneuvers of the Thunderbird opposing solos. But there is a way you can add to the experience by monitoring the performing teams’ radio communications. With a radio scanner in hand, you will experience a whole new perspective of the show that few attendees will get—the radio communications from the aircraft cockpit of the show performers. Larry gives you the frequencies you need to complete the air show experience.

Drones 101: Learning to Fly Small Unmanned Aircraft Systems
By Mario Filippi N2HUN

Over the past few years, drones, known to the Federal Aviation Administration as small Unmanned Aircraft Systems (sUAS), have exploded onto the consumer scene, and their popularity keeps growing. Once found only in hobby shops, drones can now be purchased at big box stores or on-line ready to go, batteries included. So where does one start? How does one navigate the process of selecting a drone, buying one, and obtaining some basic training? It’s a little more complicated than you might think, as Mario explains.

TSM North American Air Show Schedules

This year there’s an air show coming to an air field near where you live. Take a look at the 2018 TSM Air Show schedule for some of the more popular aerial acts on this year’s tour.
