K2 - TVI

[Darwin, Keith]

One of the benefits of running QRP is the reduction in TVI.
Unfortunately this time, it was no benefit.
 
My TV is interfering with my K2.  Usually it is the other way around but
not this time :-)
 
I have an inverted v antenna right above the house.  It is picking up
hash noise from the TV set.  The ground mounted vertical, 40 feet away,
is quiet as a mouse.  Fortunately the vertical works just as well or
better than the v so it's not a great loss.

You might try a bead balun on the inverted vee, if you do not already
have one. This will keep RF from the TV from flowing up the outside of
the coax and getting into your antenna.  Also, rerouting the vee's
feedline away from the TV or its antenna lead might help.  Finally, if
the TV has an external antenna, an old-fashioned highpass filter on the
TV set along with ferrites on the power cord will reduce the radiation
from the TV.
