Had a question for open discussion

Is there available, can it be done to have an AM and/ and or FM transmitter
that will broadcast over the entire AM and FM broadcast band at the same
time. Or at least multiple stations. E.G.

From 88 - 108 at once or 88-98, then 98-108
Same on AM band.

It would have to be a low power to be able to be used on private property
and limiy range to 300 mtrs

Can this be done, where can l buy it, or how do l make it

Told you it was a dousy of a question, whats your thoughts.

Conceptually, you're describing something similar to
ODFM, used in 802.11(a) and (g). Basically, you create
numerous independently modulated carriers across a band,
combine them and amplify them. If you're intent on
transmitting the same information on each carrier, then I
suppose a simplifying trick might be to produce a comb,
but the general case is basically identical to something
that exists already.

Now, here's a question that follows - suppose you built
an ODFM transmitter that was able to place a signal on
each 'channel' in the FM broadcast band. What could
power-level/signal-strength would be permitted under
Part 15? Would the aggregate ODFM signal be considered a
single signal for Part 15 purposes, or would each 'channel'
be considered an independent signal (since, technically, it
is)?
