[ARC5] Receiver input impedance.

[Bill Cromwell]

I'm a relative newcomer to the aircraft radios but I understand the
antennas were a wire dangled out the back of the airplane. Certainly not
a beverage. Far from a 50 ohm dipole. I like Dave's idea:

1.  Hook up your loop.
2.  See if it works.
3.  Be happy.

I have used a "tuner" in the line to the receiver several times in the
past and it can make a difference. I plan to do it again. But the
experiences I had needed to adjust the tuner when I QSYed very
far...just like for a tube transmitter final. Whatever kind of
transformer we install inside the radio is probably only going to put us
in 'the ballpark'. The idea does have merit. An external tuner may have
even more merit.
