A Solution Without a Problem

Paul Thurst, writing in his Engineering Radio blog in a piece entitled “HD Radio: A solution without a problem,” took another chunk out of the bloated blather hyping HD radio in a recent column, saying at one point: “One of the station that I service had a Harris Deathstar go off line for four days. NOT ONE PHONE CALL, NOBODY CARES!” Paul is an honest-to-god engineer, as you can see quickly by perusing his blog. Much of the material is way over the head of the novice, and light years beyond what’s passing as “educated” talk about the great scam of IBOC (his alternate title: “A solution that causes more problems”). Says Paul:

Naturally, HD proponents will cry “But this is only temporary! Wait until the transition to all digital!”


If HD radios were indeed flying off the shelves as iBiquity claims, and if the public expressed interest, okay, maybe. Clearly, that is not the case. The only thing that HD radio is doing is creating more interference. Period. More interference to the parent station and more interference to the adjacent channels all for an audience that does not exist. Another way to put it: NOBODY IS LISTENING.

The conclusion of a bona fide engineer (as opposed to those make-believe engineers at NPR Labs and iBiquity with their false claims and fudged data):

Lets see where FM IBOC stands:

  • Rolled out with 1% digital power vs analog carrier, the system was found to lack building penetration and generally performed poorly in mobile listening environments (NPR labs study, Nov 24, 2009)
  • FCC allows up to 10% digital power vs analog carrier to overcome these problems, a few stations implement some type of power increase
  • The  shows that self interference is the largest problem IBOC needs to fix, one that is un-fixable due to the laws of physics
  • The public yawns, turns on their iPod

IBOC is a failure, both in AM and FM bands.

We are watching the self destruction of radio broadcasting in the US.
