JARC Joplin Hamfest

Once again the  Joplin Amateur Radio Club put on a great Hamfest! The SEKARC table was a success and next year I think we will need to get TWO tables! The club made some money from the sale of some donated gear and many menbers that brought items to sell, did so! This years fest was even better than last years. Several of us got to meet Bob Heil as he stopped by our table and with our table being right next to Big Larry NØMST there was always entertainment going on!

Build An AM Radio In A Box

Here is a great little project... an AM radio receiver with amplified speaker, using a 9 volt battery! Schematic is included. If anyone decides to build one of these, take pictures and take notes. It would make a nice follow up article.

Also, does anyone have a cool box, or an idea for a box to use for this project?
