WDET Broadcasting on 101.7 and 102.1

[MWmetalhead]

I think WDET is transmitting an analog signal in sidebands intended for HD (hybrid digital) transmission.

I'm about five or six miles to your SE, Colonel, and I'm hearing a pretty clear analog signal from WDET at 101.7 MHz and a not quite as clear (yet still unusually strong) signal at 102.1 MHz. If I were tuned to 101.8 MHz or 102.0 MHz, that wouldn't necessarily be unusual, but it certainly isn't something I should be hearing at 101.7 or 102.1 MHz!

Definitely something going on from a technical standpoint that demands immediate attention from WDET's engineers.

I'm pretty sure 101.5 the River had the same thing happen a few months ago. Transmitting its analog signal on 101.3 and 101.7. It was fixed a few days later. I know bleed-over happens on stations that have bad or no signals, but this with WDET is much different. I hope enough people are complaining.

The issue can be caused by RF feedback, a common problem in tetrode-based tube transmitters that are not properly neutralized.

If they are on an old backup transmitter, these could be the cause.

As of today, Sunday, January 17th I am no longer hearing WDET on 101.7 or 102.1. What about your reception?

Ditto for me. The spillover onto 101.7 & 102.1 is no longer occurring. The audio on 101.9 is noticeably louder than before. During quiet segues, I'm noticing a slight AC hum (it's not loud enough to be bothersome and one has to listen closely to even hear it). Perhaps backup equipment is now being used.

Didn't notice at all today on my radio.
