TH-D7 series :

This transceiver, first introduced in 1999, was updated with the TH-D7AG and TH-D7E2 models. Enhanced versions with new TNC, TNC firmware, and selective calling features.

TH-D7 legacy :

This portable transceiver in 2010 was replaced by the Kenwood TH-D72, an advanced radio with a built-in GPS receiver unit and GPS Logger.

TH-D7A / E cursor keys :

This transceiver employs 4 cursor keys so that you can program most of the functions with only one hand. The UP/ DWN keys function in the exact same way as the Tuning control. These keys change frequencies, memory channels, or other selections, depending on the current transceiver mode.

Note 1: 3.5V is present in this line. Note 2: A 10 uF capacitor is not required when the other equipment has DC blocking capacitors or when a 2-terminal electret condenser microphone is used.

TH-D7A / E external equipment :

When connecting an external speaker, an external microphone, or other equipment such as a TNC for packet radio to the SP jack or MIC jack, refer to the diagram below.

Note 1: Voltage is developed across the 100Ω resistor in the 3.5V line in the transceiver. When 2 mA flows, approximately 3.3V is developed. Note 2: A 10 uF capacitor is not required in the following cases, when the other equipment has DC blocking capacitors, when a 2-terminal electret condenser microphone is used.
