[SixClub] Different 6M Antennas Different Noise-Level

[kd4e]

Interesting thought.

My rig is a Yaesu FT-857D.  I toyed with the 2.1KHz filter, the noise 
limiter,
and various combinations of DSP.  Will have to consult the docs re. IPO.

I may have an unidentified source of local QRN - the delta loop is 
closer to
the house by 50 feet than the feedpoint of the dipole - I may try to 
relocate
the delta loop and see if there is a difference.

Thanks!
