Examples of functions that can be assigned only to the PF keys:
• DATA SEND function:
When modulating the signal using the ACC2 or USB audio input located on the transceiver s rear panel, modulation
signals other than those at these microphone connectors are muted, whereas there is no modulation with the audio input
through the connectors on the rear panel if a transmission is made with the [SEND] key on the front panel. In such a case,
it is convenient to assign DATA SEND function to the PF key.
• TX TUNE function (TX TUNE 1, TX TUNE 2):
A continuous carrier with a certain output level can be sent out regardless of the current settings of mode or transmit output
level. This function is very convenient for tuning a screwdriver type antenna tuner or adjusting a linear amplifier.
For TX TUNE 1, pressing the key each time enables or disables TX TUNE. For TX TUNE 2, the TX TUNE function operates
only while the key is pressed.
By assigning frequently-used menu items to the PF key, the menu item can be called by a single touch.
Hints and Tips
● Extension of PF function
PF keys can be increased by creating a circuit for switching the voltage signal input to the MD and MU terminals of the microphone
connector using an external switch. (Refer to the circuit drawing example)
If you have a microphone equipped with the PF keys such as MC-47, you can assign the PF function to the microphone PF key
and the UP or DWN key.
You can configure the microphone PF key using Menu 94 ~ 99.
Caution:
◆ The figure shows the microphone connector viewed from the front panel, but it is inverted (upside down).
◆ The circuit only shows the connection of DC signals. Be fully aware of loop interference of radio frequency signals and other
possible issues that may arise.
◆ We will not accept any request for fixing problems arising from connecting devices other than KENWOOD's genuine optional
products regardless of the content of this document.
