Kenwood TH-D7A(G) Dual Band Handheld
Product Review QST April 2008
Kenwood’s TH-D7A(G) is a full featured dual band handheld that works well, is easy to use, and expands on the original model’s APRS capabilities.
The Kenwood TH-D7A(G) is a unique dual band handheld radio that has integrated Automatic Packet/Position Reporting System (APRS) functionality with a built-in terminal node controller (TNC) and APRS firmware. We reviewed the original version, the TH-D7A, in 1999. Physically, the ’D7A and the ’D7A(G) appear the same, and the FM voice features are comparable. The big difference is that the G version has significant improvements to the APRS functions, along with some other changes that are addressed in the Enhanced Features manual that comes with it.
This 28 page supplemental manual is dedicated to explaining operation with the new and changed features. Although the G version has been available for several years, it has not been reviewed in QST. We thought it appropriate to look at the G version considering the extent of the changes and the popularity of APRS operation today.
The TH-D7A(G) offers 5 W output, extended receive coverage including the AM aircraft band and NOAA weather channels, CTCSS decode/encode, memories and scanning and repeater options and DTMF dialing and memories. The radio also supports Kenwood’s SkyCommand II system for remote control of the TS-2000 series HF radios. The A band receives the aircraft band and VHF, and the B band receives VHF and UHF. As a true dual receiver radio, you can listen to both bands at the same time;
Readers are encouraged to read the thorough review of the original TH-D7A for a presentation of the core features, and to better appreciate the changes incorporated in the G version. ARRL offers several resources that may be helpful to those who are not familiar with APRS operation.
