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

Hi Wayne and the list,

without having actually testing this:

> * EU REPEATER 1750 HZ PL TONE BURST: If a 1750 Hz
> PL TONE is selected, a 500 ms tone burst will be
> sent on each PTT activation.

This sounds wrong.

During a normal QSO the tone is only needed once. Here in DL the  
1750Hz tone is used to "turn a repeater on," and it stays active until  
it no longer detects an "incoming" signal for 10 seconds or so. In  
other words, transmitting the tone as a kind of inverse roger beep  
would be very irritating.
