Att (Front End Attenuator); Digital Voice Recorder Operation (Dvr) - Yaesu FT-920 Operating Manual

ATT (Front End Attenuator)

Under conditions of extremely high signal levels, the
front end attenuator may be engaged, either singly
or in conjunction with the IPO feature, to reduce re-
ceiver sensitivity.
Pressing the front panel's [ATT] key repeatedly
causes the attenuator to cycle through the various
levels of attenuation provided (in 1 S-Unit steps of 6
dB each):
6 dB Þ 12 dB Þ 18 dB Þ 0 dB Þ 6 dB Þ . . .
The "0 dB" position, of course, represents the "At-
tenuator Off" configuration.

Digital Voice Recorder Operation (DVR)

The FT-920 includes a built-in Digital Voice Recorder
which you can use to record and then replay the in-
coming signal (from the VFO-A path) for a period of
up to 16 seconds. In addition, the DVR may be used
for storage and replay of repetitive ("CQ" type) mes-
sages in your voice. See the section on 'Transmis-
sion" (page 50) for details of the latter feature.
Recording and playback of incoming signals is
straightforward.
Q While receiving, press the [R
(50 MHz), to start recording. The recording level
is set automatically, so you may leave the listen-
ing volume at a level which is comfortable for you.
During recording, the hyphen in the Memory
Channel display field will blink.
R To stop recording, press the [R
tarily again. The last 16 seconds of incoming au-
dio will now be stored. In this way, you can quickly
confirm, for example, if a DX station correctly cop-
ied your callsign through a pile-up.
S To play back the stored audio, press [P
[0] (50 MHz). For playback, the front panel's [AF
G ] control sets the volume level. Incoming sig-
AIN
nals, however, will be cut off for the duration of
the audio memory playback.
