[EIDXA] Waht are you seeing DQ

[Nelson Moyer]

Rick's comment reminded me that I once had a cracked coax in the rotor loop
from flexing stiff coax in the cold. I noticed it because of fluctuating
signals in the shack and then noticed fluctuating VSWR. Upon inspection of
the coax, the shield was corroded along the split, and about three inches
into the insulation on either side. I replaced the short loop section and
all was well. Another time I had strange behavior on the TH-11 was when the
balun failed and had to be replaced.

Scott,

My only comment is that 9913 is notorious for filling with water.  Do you
have a coax problem?

Does not explain the signal peaks and valleys.
