As we have shared in previous posts, it's generally agreed that low power AM broadcasting under Part 15 has the best opportunity for useful legal range, due in part to the opportunities for experimentation under the "100 mW power input and 3 meter antenna" subpart in the regulations.
Happily, there is a nice selection of certified Part 15 AM transmitters and Part 15 compliant (meaning the transmitter complies with the letter and spirit of Part 15 without being certified by the FCC), AM transmitter kits on the market today.
Of course, quality and compliance can be expensive and kits require a significant investment in time and a certain skill level to complete, so, which AM transmitter is best?
I think we can all agree that "best" means range - so, of the popular AM transmitters on the market today, which has the best range? Sure, you can research online but all I've ever been able to find is a wide range of opinions and hyperbole and very few facts.
Wouldn't it be great if an unbiased report were created, where sensitive measuring equipment was used by skilled operators to test a collection of transmitters in a straight up, head to head, identical conditions comparison where we could learn once and for all which transmitter would deliver the best bang for the bucks (or effort)?
Enter the Hobbybroadcaster.net AM Transmitter Challenge, a Herculean effort undertaken by the talented and dedicated Bill DeFelice and a cadre of capable assistants who put in the time and, from the sounds of the report, no small amount of work in designing, coordinating and delivering the final word on legal low power Part 15 compliant AM transmitter range.
So, which one won? You'll need to visit Bill Defelice's most excellent web site dedicated to legal, low power radio experimentation, www.hobbybroadcaster.net, and find out for yourself.
Check out The AM Transmitter Challenge on Hobbybroadcaster.net and start planning your Part 15 compliant operation today!
A huge lowpowerradio bog "Thank You!" to Bill and his team for their selfless efforts in finally settling this contentious topic with a repeatable, fact based approach to range measurement.
