To put it properly -
Keyed sidetone, also known as "modulated CW" is of questionable legality
below 50.1 MHz. It is also poor engineering practice and generates
significant QRM due to carrier leakage, noise/hum modulation,
clipping, and "open mic" noises when a microphone is also connected to
an SSB transmitter at the same time (as it would be between the
dits/dahs).
All of those issues can be observed nearly every day on most HF bands
thanks to the CW by MCW (tone keying) capabilities of both fldigi
and HRD/DM780 in the hands of users who do not understand that the
SSB transmitter and modulation needs to be absolutely pristine and
the microphone disconnected in order to generate a clean CW signal
through tone modulation.
Again, keying the sidetone into the mic input is a grotesquely bad
idea.
