I'd bet the bigger hurdle would be convincing the users to adapt all those
individual radio to add tone encoders. There's a lot of ancient hardware in use
on 10m.

John,
The old HyGain AM/CB to FM/10m conversions were a snap to set up for 100 kHz

Brian,
You described it as "not decoding" but then say the audio is "routed around

So with the decoder installed can you roll the squelch open and still hear
the speaker? If so the decoder is not getting a signal to RX mute.

Those are all good ideas.
Don't forget there are 10M repeaters outside of the US also use the

It seems that someone once told me that in the early days of 10 meter FM the
first repeaters were all 29.60 input and 29.69 output, this allowed for people
to only need an additional receive channel if they already operated simplex.

Comm-spec even gives instructions on how to make CTCSS work on AM CB radios!
Really, 10 FM radios are so plentiful, that uncertainty regarding how well a
converted CB would work with CTCSS is not practical. Besides, I'll bet the
bigger technical challenge would be to get a converted CB to do 100K
Here is a thought - I got caught on this once upon a
time - the dip switches on the CTCSS board have to be
OFF in the indicated positions to decode the tone you
want - not ON as you would expect.
