NAB is interested in testing all-digital on the AM/MW band in the USA. I say the only way to be able to make the right decision as to what method is best for AM digitization is to permit DRM broadcasting on MW during this test phase. DRM has been OK'd for SW by the FCC but iBiquity has locked down AM and FM bands with the IBOC HD format.Problem is, iBiquity HD AM has been shown to be a real dog, with many stations attempting to use it shutting it off due to poor performance. The iBiquity HD AM simply can't stand up to the rigors of skywave propagation. DRM on the other hand is ideal for groundwave and skywave conditions alike. HD is fine for FM but DRM30 is THE solution for digital conversion of the LW, MW and SW bands, hands down! We have years of research worldwide to prove this point. Who can we rally to challenge iBiquity on AM in the United States?
