If they operate at 18.110 , which is end of digital/RTTY band - Yes , if any OO's are paying attention.
The rule reads  18.068 - 18.110 is RTTY, data, but is clarified further down the page as:

97.307(F) Only a RTTY, data or muliplexed  transmission using a specified digital code listed in 97.309(b) of this Part
may be transmitted.The symbol rate must not exceed 19.6 kilobauds. A RTTY, data or multiplexed emission using an unspecified code digital code under the limitations in 97.309(a) of this Part  also may  be  transmitted  The authorized bandwidth is 20 kHz.

Have an older copy of Part 97, so this wording may have been changed.???

On SSB  many get "caught" by operating on 14,350 because the bandwidth of a SSB signal is a tad over 3 KHZ and on 14.350 that would put their modulation products at 14.353;  running a KW amp which is overdriven and splattering would put a station even further out of band.  So it's always a good idea to leave your signal a "guard band" to insure you're in the proper part of the band. On SSB , it would be 3.5 kHz above/below band edge.

Best to read Part 97 yourself and get a big city lawyer to translate

Thanks for keeping me honest Jerry

Randy:

If you  go to 18.110+ 1400  you will be OUT OF BAND !!!!

Read your Part 97.307(f), please .  18.110 + 1400  will put you out of band and you'll probably get a Official Observer Advisory Notice.
