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

[Alexandr Kobranov]

Hello Wayne and the list!

Just idea about two future developments:

1) redisign this as for Roger-Beeb (at the end of transmit) for any 
voice mode (FM, SSB) - maybe with some tone to choose (sometimes CW 
"K" on higher wpm used also)

and

2) allow it (1750Hz tone) as a possible option for FM only as a 
function of TUNE button (or other one button), just to use it when 
needed without relation to PTT and permanent presence in TX signal

*of course, all switchable options for R-Beeb and FMrepeater friends 
only ;-)*

Surely now implemented 1750Hz beep will start repeater here (if this 
one is sensitive to this) so this is working for now - no doubts.

Many thanks for last f/w!
73!
