Kyle Drake, LPAM engineer and evangelist extraordinaire, last year put together a comprehensive guide to building and operating LPAM stations. Originally, only hard copies were available, and then for a small fee. Now, Kyle’s released his LPAM handbook in PDF format (2.3 MB) under a Creative Commons license.
This manual is amazing: 100+ pages detailed information on how to get the most out of medium wave. There is no other resource like it. It is essential reading and reference for anyone serious about LPAM broadcasting.
