Kenwood TH-F6A/TH-F7E Protocol Specification
This document describes the serial commands used to program and control the Kenwood TH-F6A/TH- F7E handheld transceiver via its serial port.
Introduction:
The Kenwood TH-F6A/TH-F7E transceiver can be programmed through the serial port using a suitable interface optional PC interface cable (PG-4P). This allows memory management (as used by the Kenwood MCP software) as well as software control of the radio.
The information obtained for this document was gathered using the following equipment and software:
Apple Macintosh 17” PowerBook 1Ghz G4 Computer.
ZTERM V 1.1Beta 7 Terminal Software.
BBEdit Version 7.02 Test Editing Software.
Microsoft Word X for Macintosh – Service Release 1.
KeySpan USA-19QW USB to Serial Port Adaptor.
Kenwood TH-F6 FM Transceiver.
Kenwood PG-4P Programming Interface.
HP 18180A RS-232C/V.24/RS-449 Serial Port Interface.
HP 4952A Protocol Analyzer.
Here’s how I did it. I wrote files that contained all possible one, two, three, and four letter commands using BBEdit. These files also had each command alone or with a “0” following each command. I sent these files to the TH-F6 using the “Send Text…” menu command in the ZTERM terminal program. Monitored and recorded the communications using the HP 4952A Protocol Analyzer. Edited the recorded responses from the TH-F6 using BBEdit. In BBEdit, I setup a regular expression that searched for a response from the TH-F6 that was not a “?”. Recorded the commands that had a valid response. Then I went back, with much patience, and “played” with each valid command until I determined its function and syntax. The results of my research were recorded in Microsoft Word.

Dual Tone Multi-Frequency, or DTMF is a method for instructing a telephone switching system of the telephone number to be dialed. The DTMF dialing system was developed by AT&T in the 1960s and was deployed within the AT&T telephone network as a way for customers to direct calls using in-band signaling. This was marketed by AT&T under the registered trade name Touch-Tone®.
The DTMF system uses eight different frequency signals transmitted in pairs to represent sixteen different numbers, symbols and letters. This table shows how the frequencies are organized. The frequencies used were chosen to prevent any harmonics from being incorrectly detected by the receiver as some other DTMF frequency. The transmitter of a DTMF signal simultaneously sends one frequency from the high-group and one freqency from the low-group. This pair of signals represents the digit or symbol shown at the intersection of row and column in the table. For example, sending 1209Hz and 770Hz indicates that the "4" digit is being sent.
