5696u open mic bridged comms channel?

[McRadioface]

Over the past few days, theres been a streaming type of transmission on 5696, Rather than speculate on it with my crackpot theory, theres a ton of chatter on it with phone conversations, radio check-ins, search and rescue operations, windows dings, iphone ringtones and yes, ALE.
It only dropped out for about an hour and a half at 0500 UTC during the past 24 hours Ive been listening to it.
Often there are top of the hour radio checks or chatter and sometimes piped in music or entertainment audio.

Thanks for adding to this, I'm not crazy after all wow was there ever a ton of stuff to hear on this frequency during this period.

I can believe there was a ton of stuff to be heard on this frequency during that period being that of a hot mic in the COMMCOM Op Centre. The Op Centre has remote links to various receive and transmit sites and one can only speculate that the console was somehow latched in the TX position. I enjoyed listening for 30 minutes but by virtue of professional courtesy I had to advise them of the issue. Left to be seen if anyone reaches back and says thank you. Radio silence (no pun intended) so far.

Figured it was Cutter Healy, you get the same?

It was US Coast Guard Communications Command (COMMCOM) Op Centre.

Here is a nice diagram of the communications systems network:

This is the Atlantic region facility:

5696.0 kHz has 2 transmitter sites registered; Chesapeake, VA (transmitter apparently in Pungo, VA) and San Diego, CA (transmitter apparently in PT Reyes, CA).

I have looked around the base in Pungo using Google satellite images but have yet to locate the antennae field. Large area and nice looking base.

Common frequencies are 5696.0 kHz, 8983.0 kHz and 11201.0 kHz.
