I haven't tried to hear the "A" beacon on 2097 yet but have not been able to hear any of the 4 MHz beacons in central Illinois yet this winter. I'll keep listening, though. Best times in the past have been a couple hours before sunrise during the winter. I've heard most of them in past years.
Is the "CO" beacon on 3449 kHz defunct? I haven't heard it in a long time and see it's not on the list of current active beacons.
