6 meter interference - channel 03

[Bill Glaze]

Interesting.  I wrote earlier today about flying about 300 yds. from a 
2000 ft. antenna.  I flew on 6 meters, until recently (need to get my 
license renewed), and never had a hit.  Mostly on ham band 04, 03, and 
some on 53.1; I'll have to take a look at my collection of modules and 
see if I have anything below 51 MHz.  Of course, the 50-50.1 custom on 6 
meters as a set-aside for CW only, is just a "gentleman's agreement" and 
is not a law.  Still, most seem to abide by it; but there's always a guy 
or 2 that doesn't get the word.  Have you been able to hook up a set of 
headphones to check and see if you can hear anything?
