Is AM RADIO still relevant? Absolutely! I listen to AM every day. I live just East of Fort Smith, AR my station of choice is KPRV-AM, 1280 in Poteau, Oklahoma, about 30 miles away...this wonderful station is an Oasis in the AM Radio desert. I say this because KPRV is the only station that acutally plays music worth listening to. The music is a satellite-package known as "America's Best Music" a mixture of Adult Standards with ieavy emphasis on music from the 50s&60s. KPRV is a CLASS D station with 1000w daytime and 100w at night. I get good listenable receprtion during the daylight hours up to 4pm, when the inteference starts rolling in (this post is being written in December). I realize that the AM band has a number of serious technical challenges to deal with, the programming on most of the AM stations I've heard lately, stinks! It seems that with very few exceptions, all that can be heard on the AM Band is one talk show after another...the names Rush Limberger and Glenn Pecker come to mind. It seems that whiever gets the most people angry fastest, wins! Yes there is a definate need for some major technical improvments, and at least some of these should be implemented, and after the refinments, how about some decent programming? without some quality programming, all the technical refinements will be in vain. I think AM (maybe FM too) should remain analog. As far as I know, DIGITAL AM has created more problems than it has solved. CRAP is CRAP, whether the signal is digital or analog, so let's improve the programming too! I'm not very warm to the idea of moving the smaller AMs to the low vhf band, but if this should be done, the migrating stations should remaing analog, as there are millions of portable radios out there that can tune the old analog TV channels..Make those technical improvements, then give me something worth listening to. KPRV-AM has what I want to hear, my time spent with this station is time well spent...Yes AM radio is still relevant and can be even more so, when there's something worth listening to!...steve, Lavaca, Arkansas.

AM became a synonym of low quality audio reception even without being affected by any sort of interference. This has to stay as a fact since it seems FCC has no idea yet about the new economical technique concerning AM systems. Because now, a new DSB-SC detector (not Costas Loop or similar) could be implemented even in low-cost radio sets with all the benefits of synchronous demodulators and with the Automatic Frequency Control (AFC) function found in FM sets. On the side of the AM broadcasters, their transmitted energy will be of the two sidebands only since no carrier is needed. And if some will be allowed to double their bandwidth (during daylight for example,) they can broadcast HI-FI music (up to 16 KHz)! Unfortunately this almost ideal AM communication cannot see the light till FCC will have the time to understand the new DSB-SC demodulator which can replace the diode detector for almost the same cost. Obviously the new radio sets will be able to receive an AM signal having any AM index.
