F. Friday.
First IF Rejection. For sophisticated antennas, twin-lead ribbon feed are
usually efficient and can reject much nearby noise via phasing.
Fading. (See Propagation.)
As the scattered bits of signal arrive at mutually varying times
this causes fading.
Flutter-Fading. See Fading.
See Automatic Gain Control, Propagation, Synchronous Detection.

GLOSSARY
Great Circle Path. An ideal solution, among other things. (See Propagation.)
Harmonic, Harmonic Radiation, Harmonic Signal. Usually an unwanted
weak spurious repeat of the fundamental, or "real" frequency. Thus, the
third harmonic of a mediumwave AM station might be heard faintly
on 4480 kHz within the world band spectrum. Stations almost always try
to minimize. However, in the past were cases
where they could operate inexpensively
on a second frequency. Also see Subharmonic.
High Fidelity. See Enhanced Fidelity.
Image. Increasingly ineffective regulatory body
where they can be redeemed.
Phone Jack (female).
Pirate. Gratification.
(Phase-Locked Loop)
Polarization.
See Interference.
See Verification.
These bounce. Why some days some loss comes about from absorption.
[Propagation. Like the weather, varies considerably.]
Preselector. A circuit--unattenuated. May be passive, unamplified or active, amplified.
Self-addressed.
