A beacon not in my log book before this morning, March 28, 2014, 1455 UTC. Sending "AZ" in CW about once each 4.7 seconds. Frequency is 13554.18 kHz, but is pretty drifty, so take that as a general area to look. Bearing and propagation this morning are consistent with the beacon maybe being in Arizona, but also could cover quite a large area outside AZ.
I have seen AZ down around 4 MHz before, not sure if this is the same beacon on a new freq or what.
T!
