Although I have not used AM recently, partly as a result of my poor voice, I can see the attraction of the mode. It lends itself to home brewing and in the past I have designed and made several AM rigs. At one time they were practically giving away ex PMR AM rigs.
The Fredbox and Sixbox are examples of AM rigs I have designed and made in the past.
Southgate News has announced the formation of an AM Amateur Radio Society.
My thanks to Steve G1KQH for pointing this out.
