Electric Radio Magazine is a technical publication that revolves around vintage amateur and Military Communication modes. VHF, UHF, HF, RTTY and other modes are welcome. While I can't post the whole article on here I can send anyone my original PDF that I sent in. Here is an image of the first page of the article. I would highly recommend anyone who has an interest in vintage radio subscribe, its not digital so you will get a monthly hard copy and the price is reasonable. http://ERMag.com
