FM Radio in a Mint Tin

If you know me, you know I like to build electronics. It doesn't always have to be radio-based, as I've built many things using Arduinos and Raspberry Pis. Today, I want to put something together that is both practical, fun and creative! And one day, it could even be useful in emergencies when information is crucial.

More CB Goodies: AM to CB converter

 Another impulse buy, but one that has lots of historical significance and one that sparked my curiosity. What came in the mail this time?

Hammo Can 2.0

The project that was supposed to be but evolved into something else.

If you recall a few years ago, I built a portable battery box using a $5 plastic ammo can. It works phenomenal with my CB and ham radios. If I need a 12V source to test circuits with, I can also use it as a portable power supply. But what about my original idea?

Cobra 21 LTD Classic Mic Conversion

From one of my eBay escapades, I picked up an older Cobra 21 LTD Classic. It was a really clean radio and I really like it actually! A step up from the Cobra 19 but with Cobra's Dynamike control. I received it without a microphone, however it didn't matter what microphone I tried. I would always get around 20 to 30% peak modulation. What's going on?

Midland 13-857: An Unexpected Joy

 After the initial failure of the 13-853, I decided that I needed to send it off to a local CB shop for repair. In the meantime, I purchased 3 more 23-channel CBs for conversion - just in case :). One of them is a Midland 13-857 - the coolest CB radio I've ever owned.

CB to CW PART 2

 In a previous post, I briefly discussed a way to convert an AM-only crystal-controlled CB radio into a 10 meter QRP CW rig with some additional features. Now that I've discussed the theory, I've written this post to track my progress and give you some information should you want to do the same.

My Thoughts on Citizens Band

 So I'm not one for making opinion posts...but...

I want to make it clear - CB radio is what got me into ham radio. I remember going down to clean out our basement one day when I was about 10 and I stumbled upon a bluish-grey metal box with a mic coming out of it. It was a Roadmaster (Royal Sound) RE4000 CB radio - and it changed my life forever. And for all you CBers reading this post - I hope that I can speak for all of you...

Listening to DX AM stations

Yes, including transoceanic ones!

Recently, I picked up some TA7642 chips from Amazon on a whim. Originally, I wanted to make a shortwave receiver with an external BFO for a QRP project, but I learned that these chips only worked up to around 3MHz. However, not all hope was lost.

Zenith Royal 20: An AM radio House Find

 Over this past weekend, I headed east to help clean out my grandpa's childhood home. It will be demolished in the next few weeks but it still had some things in it. One of those things was a Zenith AM radio - cool! I'm a huge stickler for AM radios. I love listening to stations over 200 miles away at night and I love the warm tone of AM. This is fueled even more by my amateur radio passion.
