TV for one million: Exploring KSDK's broadcast tower

KSDK-TV broadcasts to well over 1 million households in the St. Louis metro area. And my Dad and I went to their broadcast tower last month to explore how the digital TV signal is delivered through the air to so many people.

On our tour, we explored over 75 years of television broadcast history, seeing how things transitioned from thousands of volts down to hundreds, and from analog audio and video to all-digital.

And we even found strange artifacts of the past, like this random microwave dish that received a signal through the roof of the broadcast building for a time:

My Dad and I just posted a new video on the Geerling Engineering YouTube channel where we explored the tallest radio tower in the St. Louis metro area, the so-called 'Supertower' that has a 10-station combined dual FM antenna system (dual 4-bay FMVee by Dielectric) at the top:

Review: iRig mic for iOS and Android

Jeff's Rating: 4/5

tl;dr: Great-sounding, reasonably-priced microphone, purpose-built for the smartphones and tablets, with few downsides.

The iRig mic was introduced in 2011, and promised to be one of the best ways to get sound from your mouth or instrument into the iPhone 4, iPod Touch or iPad/iPad 2. Since then, it has been tested to work with newer iOS devices like the iPhone 5, and many Android phones. I've updated this review (in 2013) to reflect my more extensive testing since I originally reviewed the microphone in 2011.
