The Ramsey AM25b Re-Purposed
I've seen this paper before and have a printed copy because the Carrier Current use of the AM25b is an idea to think about.
I happen to have an AM25b which is not in use because it wasn't equal to the SSTran transmitters, but it could still have a future.
Buried somewhere at Part15_us is a modified version of the Ramsey AM25b re-engineered by Radio8Z which improves many of its weaknesses.
My brain has wondered whether both of the above mentioned modifications could be added with a switch between the two choices.
Still another thought is to use the AM25b as a transmitter for 1710 kHz at the pea-power allowed for that frequency.

The Man Is Right!
DHR said: "Let the good times roll on 1710. One can't spend one's entire life being a victim."
Carl Blare stood up and raised his voice: "That's right!" he exclaimed. "That man is right! An open frequency is the same as a picnic area in a public park! If other picnickers aren't using the space it should be o.k. to spread out and even go over the line beyond the picnic area!"
Carl was on a roll and continued screaming: "We are not victims! We are the public! The airwaves and the parks belong to us! Stand aside! The owners are here to use their grass and their radio frequencies!"
Carl kept ranting but the rest of it didn't get typed on the keyboard.

From the FCC:The fact that there are locations on a radio tuning dial which do not receive a broadcast station, does not necessarily indicate that a station can be added on that frequency. A station's signal on the same frequency or an adjacent frequency that is too distant or weak to be picked up by a radio receiver can still cause interference to other broadcast stations. For this reason, the Commission's rules require that stations located very close in frequency be located in different communities separated by some physical distance, so as to limit any potential interference. Before it can be determined whether any "quiet spot" could support a broadcast station, the interested individual or group would need to have an engineering study performed to determine whether the frequency can actually be used. The Commission does not have the resources to perform such searches for potential applicants. Interested parties may want to retain a broadcast consulting engineer (WE HAVE ONE) to determine what options exist, incorporating factors not under the Commission's jurisdiction (such as environmental and land use limitations, property availability, zoning, and airspace considerations).

Worried At First Then Relaxed
That was an experience reading through that stern FCC "dressing down" about feeling too free about using open frequencies and I began to think I was being asked to take it somewhere else...
But then came this:
DHR said: "We can do our own evaluation and approve ourselves."
Right then I knew that DHR knows what it's all about.
