No Digital Synchrony on KVIL (ops...) LITE-FM

J

JRZFM100

So I just purchased my first ever HD radio. It was a long search because my main objective was to get an HD tuner with "forced analog" - as to be able to force the receiver into analog mode to make a direct comparison between FM and HD quality.

With my tuner set in the auto-blend mode, free to auto switch between analog and HD, I noticed the music on LITE-FM would skip or repeat itself. Same skipping was observed with LITE while driving through difficult reception areas too.

Low and behold, when comparing KVIL's analog and digital using the forced analog / forced digital modes of the radio - KVIL's analog program material is NOT delayed, and leads the HD-1 program material. It was this way on Saturday evening and remains this was through Sunday evening.

KVIL's analog audio is not in time synchrony with its digital audio. That makes for a very weird listening experience in for those listening in the normal HD blended mode!
 
No one has time to correct the time delay difference as often as HD needs to have it done, and I'll bet more
than one engineer has given up, or decided to let the system sound that way to help it out of its misery as soon as possible.
Many engineers are overtaxed and haven't the time to babysit the time delay. There are more pressing issues.
 
With second generation 'all in one' analog+digital exciters (consider Harris Flexstar for example), synchronization of the analog audio delay should be a snap.... a mere button push or some other menu setting.

I also believe this feature to be available in advanced, current generation audio processors.

If synchronization were so very complex, then I'd imagine that everybody here would have some evidence of time alignment problems. This is not so. No one else in Dallas has this problem.

Then again, there is one station here with an active HD-3 channel with no program audio... its probably unintentional or they're unaware.

I would not let this happen to a station in Abilene, no less DFW.

I'd also hope that CBS management would be listening to the HD-1 and catch the discrepancy during the acquisition and blend to digital sequence which occurs every time you change the preset.

Perhaps CBS has a technical problem such as an exciter out for service or some other equipment problem.

Finally, it is sad to see that so little attention is given to the HD. Perhaps a direct result of having so few HD listeners.
