RX-AF Outputs
The volume-controlled receiver AF can be tapped individually for each radio channel on
the
Major BOS 8a.
The outputs can be used e.g. for connecting external AF-amplifier.
The receiver AF (RX-AF outputs) of individual radio channels can be muted either
- manually by pressing the loudspeaker buttons or
- automatically by activating the corresponding busy lines or
- automatically by transmitting on the active or a different radio channel
There is one
muting output
per radio channel with which the connected AF-RX amplifier
can be muted when there is no receiver signal (squelch) (output switches to GND). See
also section
Sockets Pinout.
a)
In
EEPROM register 020
a configuration for the radio channels 1..8 (
bit 0..7)
can be
made so that the RX-AF output is muted while transmitting on the own radio channel.

Encoder
Major BOS 4a
has an integrated encoder for
call 1
and
call 2.
The calls for each channel
are transmitted directly with the corresponding buttons on the keyboard (
RUF 1
or
RUF2
).
The calls are transmitted as long as the corresponding button is being pressed.
