Hi Curt

PSK31 has become my mode of preference.  I operate QRP .... 1.5w idle 
es abt 3-4 w peak.  I originally operated with a home brew 100w 
linear (tube type) with about  20w peak output ... but the amp took 
up most of the desk space so I de-commissioned it almost 2 years ago 
with the intention of getting a  modern solid state amp.  In the 
meantime i continued to operate barefoot (QRP).  I hardly noticed a 
difference.  I still worked some DX and anyone I called came back to 
me.  Calling CQ almost always brings a response.  My antenna 
arrangement consists of 2 dipoles (20 & 15) at the top of my 50ft 
tower  ..... nothing extraordinary.  The USB version of SignaLink 
does and excellent job as an interface.

If I had a less efficient antenna system I might go for a 100w 
linear.  As it is QRP works wonderfully and I have a nice clean 
operating desk hi hi.
