[TowerTalk] RFI Broadcast Station Mixing in Crank-Up tower?

[Rich Hallman - N7TR]

Has anyone had any problems with intermittent mixing from a close broadcast station with a Crank-Up tower?  I think I may have an issue with one of my towers.   Cranked up I hear mixing all over 80 meters (Every 10 KC).....Cranked down its gone.  I already eliminated the antennas.  Mixing gets very intermittent in wind as the tower moves around.

Thoughts about grounding the top section to the bottom when fully extended?  Was thinking of grounding the coax at the top and bottom of the tower?

Thanks....
