Chapter 4 Summary Of Enhancement; Band A & B; Keypad Direct Entry; Transmitting A 1750 Hz Tone - Kenwood TH-D7A(G) Instruction Manual

Besides APRS functions, the TH-D7A(G) has several
functions improved or newly added, as below. You may
refer to the given pages to identify differences from a
TH-D7A.
BAND A & B
Without switching ON the TNC, you will not see " "
which indicates the current data band. This modification
has been made because the TH-D7A(G) allows you to
select a different band (A or B) as the data band
between Packet and APRS operations. Refer to page
12 on the other instruction manual (original).

KEYPAD DIRECT ENTRY

When programming a memory channel name, Power-
ON message, status message, or APRS message, each
press of [TNC], for example, switches entry as a, b, c, 2,

transceiver will beep only when it receives appropriate
APRS or DX cluster data. Access Menu 1–5–3 (KEY
