I have a confession to make, I absolutely detest roger beeps. I used to permanently disable them in any radios which passed through my ownership.

The 'hybrid' single tone Roger Beep modules used in Ham International radios were very strident and quite troublesome - the PTT output transistor used to fail short-circuit, although you could replace the original SM transistor with a conventional transistor soldered to the pads on the module. It was easy enough to make those beeps switchable, but easier still to remove them entirely.
