Hi,

Similarly, try injecting an RF signal into the antenna jack and see 
how long it takes to show at the AF, or vanish when the signal is 
removed.  You will find it interesting.  Ultra contesters should 
stick to analogue if they want nano second responsiveness to keep 
their rate up.

Personally I don't take any notice of the monitor audio other than 
it offers a certain presence.  The original function of sidetone in 
telephones was to stop people shouting and it works very well for 
that in the K3.  That this is effective is demonstrated by the loud 
half conversations heard when in the presence of mobile phone users. 
The presence of small mirrors in UK phone boxes many years ago was a 
behaviour modifier.  Users could see a face in the box and behaved 
as if they were being observed.

Analogue echo suppressors have long been replaced with digital echo 
cancellers, much more effective.
