Anyone know what the signal on PGE's 153.665 MHz is about?

This is for the Northern Willamette Valley.

The signal has been continuous for approximately 20 minutes It's full-quieting for me and full scale on the signal meter (just like their regular repeater traffic on this frequency). The signal is modulated with a rapid pulsing sort of audio. It may be a data stream.

Comments are welcome.

Update:
The signal is still present. The dispatcher was just on this freq and advised a field unit that "something is crazy with these radios" and that another individual had contacted "communications" to sort the issue. I could barely detect the field unit under the mystery signal's audio but the dispatcher was loud and clear.

It seems they've fixed it. No more signal.

The communications guy just came on asking when "the noise" quit and stated he was on his way out to look at the voter. Apparently they had a power outage (PGE with a power outage - haha) which directly preceded the onset of this persistent, noisy signal.

I sounds like the receiver at the repeater site got unsquelched by some other transmitter, or intermod from multiple transmitters, so the repeater just kept broadcasting.

The dispatcher would come in clear because his input to the repeater is a different radio channel or a landline.

Yeah, it was some kind of an 'endless loop' situation without question. It seemed to correct itself without intervention, though, because the signal disappeared before their comm person arrived at the site and the dispatcher had no clue concerning the problem's causation (other than that it may have stemmed from a power outage situation).

And I understand the remote base concept. But thanks.
