Good afternoon Keith and Robert.
Are you referring to the olde directional LW / MF "radio range stations?"
They had five towers with the center one always on and AM on the carrier for
traffic control and weather. The others then made the signal very
directional sending "A" on two legs and "N" on the other two. IF you were
"on the beam" then you hears a steady 1,020 Hertz tone (60 Hz X 17). If
memory serves correctly this was classified as "A-9" transmission. If there
were two "exciters" feeding one mixer / amplifier it would seem that it
would just be one transmitter. IF there are two transmitters on site you
concern would be spot on.
Wow - a lot of "ifs" in that paragraph.
I experimented with scheme on the Part 15 160-190 KHz. band years ago,
keeping the input to the single final below the 1 Watt limit.
That was fun for me to reminisce a little bit!
Doc.

Hi Robert, Keith here in Amherst, NY
You are hearing WA4SZE in TN. His idea for a beacon is a simulation of an
old-style runway marker.
It's explained on his website along with a YouTube video or a fly-around.
The legality is questionable
as it uses two transmitters on the same band & location.
He also runs one on 30 Meters around 10.126. That one is totally outside
of Part 97, unattended on
a shared band where we are a secondary user...

At 28.2098 MHz I'm hearing a string of "A's" one minute forty five seconds
long then quick break and repeat? Anyone else hearing this and know what
it is? (North East of my location)
