Topband: ARRL 160

 From 13 years experience rather than detailed analysis or any knowledge 
of VE3NEA's decoding methods, I don't think that an additional 
half-space is a big problem - certainly not as compared to running 
things together - for example making TEST N4ZR into TESTN4ZR.  The 
latter makes for many bum spots of TN4ZR, TK2XX, etc.  I see those in 
numbers every contest.
