Having both a remote station which is 100% home brewed and also having 
done some contesting at W4AAW the M/M remote contesting station these 
are easy enough to overcome.

In a contest which is what after all contesting software is used for 
there is no need what-so-ever to use a paddle and little reason to deal 
with sidetone either.  Nearly all is handled with preset buffers sent by 
function keys or by keyboard entry if necessary.  I did a brief test in 
SS CW using Writelog remote. The first QSO with Randy 5ZD didn't come 
off very well as he asked for a repeat of something and I didn't have 
the messages setup correctly.  But we did get the rather complicated 
exchange done in any case.

Most went flawlessly.

Same situation with another recent test when I worked Chris KL9A who was 
in TI.  He presented at the local club and said it was no problem 
copying my call at 50.  So I hit the old increase speed to 50 and volla  
Chris of course QSL'd all.  There are few that can copy WS7I at 50 WPM.  
Barry W2UP, and Trey KKN and a few others to include Chris.

Having a latency adjustment like RemAud has is a great idea and pretty 
much handles slow pings.  My ping to w4aaw who is in Virginia is 110 
which is fairly horrible.  Yet easily adjusted out.  Writelog has its 
compression setting on the control site side.

One note is that when you have lurkers on your audio stream it really 
eats up the audio which we have found at W4AAW.

Writelog's new interface is awesome for the radio's that it supports.  
Looking forward to seeing more on the SW12!  As I may need to implement 
that as my switching is rather strange at my remote.
