Try un-subscribing and then re-subscribe.
have you checked your 'junk' filter to make
sure matronics didn't get blacklisted?

I believe that will do the job and you
don't need to put any holes in the airplane.
The 'inside' antenna does not negate concerns
for potential intermod situations discussed in
this thread. Those problems are not common.
They are transient and circumstance based.
The risks are low.

Not necessarily true. I've ordered some
-52 cores and will do some measurements
on the bench. I may have a multi-pass
toroidal balun to offer to your task.

Indeed, although my first introduction to the word--as a young Star Trek
fan--was reading "I Grok Spock" I think in TV Guide. I had no idea what
it really meant until I read the book a few years later.
