Elenco AM Radio Kit - Model AM 780

The other day at work I found some Elenco AM Radio Kits in the way back of the instrument room. It appears to be 16 years old, but there isn't any definitive date on this kit. This was a really simple kit and they provided everything including the solder. I only skimmed the instructions on a few sections of the radio because with this particular kit any entry level electrical engineer or technician would be able to see the schematic and populate the board.

The whole mini-project took about an hour for myself and this was pretty fun thing to do during a lull at work when none of the equipment was "broken". This post is probably just going to be photos and a short video showing that the kit works fairly well. It works pretty well even inside, but in fairness, Purdue has WBAA AM 920 on campus.





















These are some of the photos that I took during the progress and following is the video I took that it actually works.
 
 UGHH, I'm so sorry I took a vertical video:(

Ozark Patrol Regenerative Receiver

In 2014 I earned my amateur radio license as a General operator. To teach myself a little more about amateur radio, I purchased a regenerative receiver kit from the ham radio group Four State QRP Group that was designed by David Cripe(NM0S). It's pretty simple and was not super expensive($46.00), but I haven't been able to hear any broadcasts with it so far.

Anyways, I finally got around to soldering it a few days ago so this project of mine is a little more recent than my last post, but I'm probably going to jump around at first because I would like to get material on here first for others to see. Later on I expect to be more consistent and current with my projects.

I forgot to get a picture with the knobs.


I'm pretty proud of this.



This was a lot of fun and I was able to practice fearless soldering as I call it. The philosophy of soldering without fear. Maybe explanation was not necessary.

I have been using it to pick up weird noises, but I was unable to tune in to anyone broadcasting yet. If I get to tune in to anything I'll try to post a video.









Here's a small video of the receiver being tuned, but it does concern me that maybe I've accidentally made a musical instrument for electro-techno. Also I have to apologize for the quality of the video, I took the video with my potato phone, but I think it shows what I've built well enough.
