I suspect that'd be DYNOTRON or DYNATRON.
)And then you must remember that such messages, the format of them, and any confirmation of what / how they are used, is classified information, so people who actually know are probably not going to say much. I can say that when I was active duty I occasionally sent and received messages very similar in format to EAMs (but they were not EAMs), and that is pretty much all I am going to say on the matter.
jk but u kno I never listened for em around 06:00z...I've heard a lot like 23:00z...14:00z...I'll monitor around 06:00z more often. I fall asleep early!
In a side note, I've lost count at the number of emails that I receive from people who swear that an increase in EAM traffic means that WW3 is imminent.

I like to say that as long as it doesn't spell out WING ATTACK PLAN R, we're probably OK.
The beacons send the Morse slowly enough that you can write down the dots and dashes and decode it later. In fact, most pilots don't know Morse. The dots and dashes are printed out for them on various navigational charts next to the beacon location. However, learning Morse (called CW by Hams) can be rewarding. Go to the ARRL website and look up the W1AW code practice schedule. They transmit code practice sessions every evening on various frequencies. They put in a good signal here usually on 40 meters 7047.5 khz. Put your 750 in SSB mode and fine tune in the code with the BFO knob.
NDB stands for "Non-Directional Beacon" which actually means that the beacon transmits in a pattern equally in all directions. They are used for aeronautical navigation. The aircraft is equipped with a radio called an ADF (automatic direction finder) that when tuned to the beacon frequency drives an instrument with a pointer that points the direction to the station. This technology has been around for a long time and has been largely superceded by newer technologies the most recent being GPS. Therefore, many NDBs have been and are being phased out. Enjoy them while you can.
That beacon QT that you are hearing is a Canadian across the Lake from you located in Thunder Bay Ontario. It actually transmits on 332. From your location you are well positioned to be able to hear lots of Canadian beacons. Fortunately, the Canadians have not been phasing out their beacons as much as in the U.S. Often, the NDB is the only navigational aid available at many very remote Canadian airstrips.
However, you will need a good antenna to get the most out of your 750. That rotatable ferrite will pull in only the strongest nearest signals. The nice thing about the 750 though, as you have noticed, is the ability to connect an external antenna to the 3.5 mm jack on the ferrite bar. Go to the Universal Radio website and get a mono-mini to SO-239 adapter (their part #1619) that will plug into the 3.5 mm port. Get a pre-assembled RG-8X coax with PL-259 connectors on each end. Universal sells them in various lengths from 25' to 100'. The coax will run from the adapter to your antenna. My suggestion would be the EF-SWL antenna (Universal #2205). Or you can homebrew your own antenna with whatever wire you may have around. All kinds of antenna plans on the internet. Just be sure to disconnect the antenna when not in use to protect from lightning damage. (btw, you can also use that EF-SWL antenna for shortwave listening on your 750... get adapter Universal #2122 and connect to the BNC connector labelled SW on the right hand side of the 750 and make sure the INT/EXT antenna switch is in external EXT).
Hope this helps get you started. Any questions, just ask.
