In CW the transmitter builds its tone from the keyer and ignores the DAX TX
audio path, so the button keyed the rig and sent silence. Confirmed on a Flex:
our side reported the playback as done while nothing went out.
Only the button goes. The row stays, or a CW operator who stopped their
recording would be left with no way to resume it — and the recording itself is
still worth keeping.
