[TenTec] SS last weekend

[Ron Castro]

The thumping in the headphones on 15 meters is not an uncommon problem.  Try 
it on 10, and it will probably be more pronounced, and even more so if you 
run power.  You need to wrap the end of your headphone cable around a 
ferrite loop like the FT-240 43 or 77 mix.  That fixed the problem for me 
and for a few others here on the list.
