Many KENWOOD radios use a 6 pin DIN socket for remote control. Into some older
transceiver types the serial interface has to be installed previously. Please read the equipment
handbook or consult your dealer.

V24 levels for transceiver control. It´s intended for direct connection to a COM port of a PC.
Also these transceivers can easily be controlled by the PTC-IIpro. Just solder a 9 pin connector

3.6.2 Connections PTC - ICOM
Nearly all ICOM equipment has a 3.5 mm jack socket for remote control. Bi-directional
communication is carried out over a single wire, in order that data can be both sent and
received. 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.
