[Elecraft] 1750Hz tone in MCU 3.41 / DSP 2.37, 10-02-2009

[Jan Erik Holm]

PLEASE if you are going to keep this silly thing with a
toneburst at the start of every transmission at least
make it so that i can be switched off.
In Sweden this is not needed for repeater work, after
repeater been activated with 1750Hz it is carrier
operated.
