...Part #15 Broadcasting INFO. However, there is some. Domestically, Progressive Concepts has stepped-up the game on Part #15 'Radiating' gear. https://progressive-concepts.com/collections/part-15-transmitters/Part-15-Transmitters However, nothing commercially available, today, for AM Carrier-Current Broadcasting. So, some of us are considering making Carrier-Current Couplers via 'Homebrew' on the cheap, yet do it safely. Boomer, of AM690, has a Talking House 92mW transmitter where I did a quick set-up coupler test on 520kHz. Crude, but it did cover the immediate neighborhood. Here's another torroid-less coupler idea. Seems easy enough. If you decide to build something like this, have it fised, in-line, around 2A, for safety. More later, as we get into this. Nice Summer project, eh???
