Interesting, I have Hexie again this morning at 1118z. I heard it on the 4th at 1112z. I did not hear it yesterday, but I am not sure I tried at this time of the morning. There seems to be a short window when I can hear it.
I have something around 4096.04 as well, but it looks more like an always on weak carrier vs a dasher.
None of the other 4 MHz beacons. I did have A earlier on 2097.
