Hey Ridge, I dialed up 11175 about one hour after you posted your note that day. I was in and out of the shack after that, but did not hear a peep. Before that I was at work, but did not hear any corresponding traffic on 311.000 MHz. That does not mean anything other than they were out of my range for UHF. I am about 150 miles SE of you.
...and I just realized I was not monitoring the UHF EAM frequencies. ~ sigh ~
