Please fix the HD-1!

Post by ai4i »

We have experienced the following on stations, usually right after a major change is made such as returning to HD service or adding an HD2 or 3. It goes on for a few days or weeks until the engineer in charge figures out that something is wrong and probably gets on the horn with the manufacturer. Our receiver starts out in analog, in the usual way until it locks onto the HD1. When it eventualy loses the HD signal, it goes silent, popping between the HD-1 and silence, never to return to the analog mode. We cannot even force it to remain analog. What can we tell or Email the engineer?

WENZ 107.9 in Cleveland was doing this when I went by their tower in July.

WPRO 92.3 here in Providence won't lock in HD. The HD light just keeps flashing. If you listen to the side frequencies, the "hash" sounds like the old cable descrambing data frequency on 106.5.

I've noticed this happen with a few stations as well, the signal locks in HD mode and will not blend back to analog when the signal drops out it also flashes 'HD LOCK' on the display... you will have to force the radio to lock in analog (I know mine has a setting to do this)

the most notable culprits here in NC is WZFX 99.1 In Fayetteville & WBCN 1660 AM in Charlotte

WZFX is having issues???? I have worked out at that site and know the engineer there. Is it still going on?

Correct me if i'm wrong, but this is something that can be turned on or off by the radio station. (The ability to blend back to Analog).

The only HD processor for which I have a manual is the Omnia-6EXi, and I don't see any indication of such a function therein.

I don't believe you can force digital on an exporter, since the analog fallback is due to the HD signal falling below a pre-set threshold. Once that threshold is crossed, the digital signal is no longer "in control" of the radio and it will fall back to analog, even if there's no analog signal present. You can set the exporter the other way though, and force analog even if your digital carriers are present.

Every time I've had an HD radio "lock" on HD, it was due to a CPU issue and power cycling the radio fixed it.

The blend options are set in the exporter. Disabling automatic blending (in theory, listeners can manually switch still but I'm not sure if consumer radios can, I've never actually tried) is sometimes referred to as "sports mode" as stations will ramp down their delay so that their coverage of a sporting event is live.
