Re: [IRCA] KRKO DIGITAL

["Rick Lewis" <ricklew@xxxxxxxxxxxxxx>]

Hi Pete and All,
1370 is covered in noise, and 1360 is more affected by the noise than in
hybrid HD mode.
I believe I'm about 30 miles from the transmitter.
In this test I don't know what they've done and what they haven't done.
No question about it; KRKO wasn't decoding before the test; they are now.
As expected, their HD coverage is better.
But the bit rate isn't better, so the audio is swishy and unpleasant. The
highs are artificial, and the audio is fatiguing.
On average, the Sony takes about four seconds to decode the signal versus
about eight seconds in hybrid mode.
HD proponents would undoubtedly consider this a success.
As a listener, even putting my DX preferences aside, I expected better. I
wouldn't listen to audio like this on a PC, and I certainly wouldn't do it
on a radio.
Standard AM sounds better. It may have fewer highs, (and I love hearing high
frequencies!), but it's easier on the ears.

I tuned in to KRKO-1380 about 10:03 PDT this morning and it was operating in
normal analog. At 10:05, it switched to digital. All white noise which
extended over 1390. I couldn't tell what was happening on 1370 since the
KKMO-1360 transmitter is one mile away.
