Test EAMs on 7000 USB in the ham band

[ChrisSmolinski]

Not sure if this is an intentional frequency, but I've caught several test EAMs on 7000 USB the past few days.

Interesting catch Chris. Bellow is the transcription.

A few interesting observations.

• In the past, I have only ever heard "MESSAGE OF" when the message exceeds the standard 30 items;
• The use of ZERO is odd. It is not used as it can be easily confused with the letter O;
• The message sounded like it was being passed through a relay; and
• As noted in your video, this may have been a training exercise. The operator sounded fairly new to the radio procedures.

Definitely worth monitoring.

I have heard the use of the term "MESSAGE OF" for all lengths of message, long, short, and "standard".  But it is most common with longer messages.  And when it is sent with the normal length stuff it always makes me take note, sometimes thinking "must be a new op".

That was a US Navy station participating in a quarterly exercise.

US mil can and does use HAM freqs but not often due qrm as US mil are primary users for said freqs, HAMs being secondary users. I recall an instance of USAF yl operating in the 75m band receiving a lot of attention from lonely HAMs.
