Re: [IRCA] KRKO DIGITAL



KSL puts in enough digital sideband hash to eliminate 1150 and 1170 in Minnesota at night :-))

Rick,

If that is the case, then I do not see an all digital happening. However, going back to the early 90s, when Bob Rusk did one of the first articles on IBOC for Radio World, I thought at the time, the FCC would never okay such a noise maker. I was wrong as many were in the industry at the time. Here, the all digital on 1380 last night did not seem to interfere with 1390 as much. The bandwidth seemed more narrow, but KRKO is not a powerhouse here, so if someone like KSL decided to go all digital it may be a difference situation. KRKO is stronger than KKXA is by far, but still no powerhouse. KIRO is the strongest Puget Sound station I receive day or night, followed by KJR. KIRO has about 86 KW aimed at me. None of the Puget Sound IBOCers are really that strong here. 1090 isn't either. My worst offender is KSL, followed by probably KFBK. KFBK is not really that listenable in analog as with the high end part of the band, night fades, often they sound like they are broadcasting from a barrel. KCBS is also IBOC, but doesn't QRN as much running most of their power South. I will try for the KKXA test tonight, but I don't feel I will have much luck, not with KGDD in the mix. KKXA is almost DX here at night. KKXA IS DX days and tough to get. KGDD sends their power to the W/NW.

73,

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.
