OTHER OPERATIONS
• PHONE PATCH OPERATION
Most phone patches will work satisfactorily without any
modification to the radio. The PC-1 A Phone Patch can be
used with the TS-940S without modification to the
patch. Operation will be as described in the PC-1 A in-
struction sheet.
Recommended settings are:
PC-1 (A) RX Gain 4
TX Gain 4
Null as necessary
TS-940S Vox Gain 1
AFGain 4
Mic Gain 5
Anti Vox Max
• OPERATION WITH A SECOND RECEIVER
If you prefer operating another receiver in place of the
TS-940S receiver section, you may share the antenna
from the TS-940S during receive-time. Flip the rear panel
RX-ANT. switch to EXTERNAL, and connect the antenna
input of your second receiver to the RX ANT terminal us-
ing 50.Q coaxial cable. Reduce the AF Gain setting on the
transceiver to zero. Mute the external receiver from Pin 4
and GROUND of the remote connector. If a linear amplifier
is also used with the transceiver, diode isolate the exter-
nal receiver and linear to Pin 4, and be sure combined cur-
rent is less than the maximum rating for this terminal.
