Topband: Any Chinese stations with Big Sigs operating on 160?

[Michael Tope]

I just occurred to me that my description of the receive situation at 
W6UE is backwards. The 160 meter flat top dipole improved the 80 meter 
receive noise floor from really deaf to pretty deaf. On 160 meters we 
were just really deaf whether we listened on the 160 meter dipole or the 
80 meter inverted-vee :-)
