Robb,
the faster slower effect reverses when you change to the opposite sideband,
clarifiers can be controversial, folk have strong opinions about it,
unlocked over here means TX & RX move together, we unlock the TX side to track the RX,
of course its better to have TX & RX track together,
no cb radio is stable on frequency regardless of what inexperienced people think,
i invented twin shift many years ago so that we could all talk in a group on our cobra 148 gtl dx's
without issues like the coarse slipping back in the notch and everybody arguing about whos on and whos off frequency, IT WORKED,
it does not matter if the group are on the correct ch frequency so long as everybody is on the same frequency, that's impossible with locked clarifiers,
people who think clarifiers should be locked don't have not much experience of talking on ssb in a group/round table or their ears are faulty,
its not fool proof because some people just can't tune into somebodys voice correctly, they are tone/pitch deaf
on average unlocked clarifiers means anybody who's ears work correctly will be on the same frequency,
anybody who's ears don't work correctly can at least be guided to the same frequency as the group so that everybody is not either turning their clarifier all the time or sat listening to half the group off frequency,
chasing each other up and down is often cited as the reason to leave clarifiers locked,
it is a myth that does not happen in practice, the opposite is true,
when there are just two people only one of them need tune in,
listen to 385 when skip is running,
that shitstorm of people all over the shop on frequency is the result of people been able to move RX without moving their TX.
