As amateurs we are perfectly entitled to modify our equipment if we
wish. We can build the whole transceiver from scratch if we want to.
The important thing is that 10.151 MHz minus the tone frequency (LSB)
is less than 10.150 MHz, ie the tone frequency must be more than 1 kHz.
If you are uncomfortable with that, then operate USB on ~10.148 MHz
instead, where the actual frequencies are 10.148 + the tone frequency
and must be less than 2 kHz to remain inside the band edge.
The USB option is simpler because you will not need to modify your
