Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features
of the FT-7800R. I know you’re anxious to get on the air, but I encourage you to
read the “Operation” section of this manual as thoroughly as possible, so you’ll get the
most out of this fantastic new transceiver. Now. . .let’s get operating!

ETTING
At first, set the SQL knob fully counter-clockwise.
Now, you may rotate the VOL knob clockwise to ad-
just the receiver volume for a comfortable listening
level, using the background noise as a reference.
To set the squelch, turn the SQL knob clockwise a
slightly past the point where the background noise is
muted. This is the point of best sensitivity to weak sig-
nals, and we recommend that you not rotate the
SQL knob very much past the point where
the background noise is just silenced.
A special “RF Squelch” feature is provided on this radio. This feature allows you to set the
squelch so that only signals exceeding a certain S-meter level will open the squelch. See
page 24 for details
