7.1.5 Connections to ICOM
Many ICOM’s use a 3.5 mm jack socket for remote control. Bi-directional communication is
carried out over a single wire. Different transceivers have different addresses, so it is possible
for more than one transceiver to be connected to the remote control cable. Further information
can be found in the appropriate literature from ICOM.

adjusts
the frequency but could not read it out.

Newer YAESU’s (FT-920, FT847, FT-1000MP) use a 9 pin SUB-D connector and V24 levels
for control, intended for connection to a COM port of a PC. Also these radios can be controlled
by the

. Solder a 9 pin connector to the attached cable as shown in the table 16.
