And therein lies the problem. No amateur transceiver on the market
perfectly suppresses the carrier. If you're using LSB to generate a CW or
digital signal, you're certainly radiating the suppressed carrier at some
level, albeit low, and it may be on or very close to, the assigned channel
carrier of some other service.

Depending on your choice of frequencies, it may even be in the passband of
that adjacent service.
