Topband: 160 skip distance

[K4SAV]

A few years back guys on this forum decided to see what could be worked 
at noon time.  There were a few stations on at that time and I worked 
stations up to 600 miles.  That will vary with band conditions.  It 
doesn't work well if there are no stations on the band.

You can observe the same thing during a major contest when there are 
stations working the band during the day (usually multi-op class stations).
