USB on 20, 15 and 10 meters, so the BFO knob will point somewhere
near the 453.5 kHz or 456.5 kHz position.
To receive a weak signal, set RF GAIN to maximum [and turn off
AGC]{
See previous note – there is no off switch for the AGC }. For
strong signals, decrease RF GAIN and increase AF GAIN.
4. Operation in Conjunction with a Transmitter
It is possible to operate in the transceive condition if the
transmitter is FL-5OB. Refer to the Figure 2.
Use as short a length of coaxial cable as possible to connect to
the VFO. When using a transmitter other than the FL-5OB, the mute
terminal must be so connected as to be open circuited to ground
during transmitting, and short circuited during receiving.
If receiver is used while disconnected from the transmitter, M & G
terminals must be shorted together.
5. Transceive Operation
Set the Xtal switch of the FL-50B in EXT OSC position. Switch to
SPOT on the transmitter and set the carrier control to maximum,
then adjust BFO PITCH for zero beat. Return carrier control to the
SSB position. Then the transmitting and receiving frequencies are
the same.
