Q: I have a Simplex/Link/Remote Base port. What commands do I enter so a transmitter has no tail?

There are several commands that change the transmitter tail. In the 7330 User's Manual, the pieces that make up the transmitter tail are described on page 11-3.  The commands are described in chapter 11.

This example is for port 1:

MPW 09 0100 0 *                       ; Courtesy Delay, 0 Second
MPW 09 0101 0 *                       ; Dropout Delay, 0 Second Tail
MPW 09 2111 0 *                       ; Dropout Message Time, 0 Seconds (default)
MPW 09 0102 0 *                       ; PTT Minimum Unkey Delay, 0 Second

MPW 09 0200 0 *                       ; Courtesy Delay, 0 Second
MPW 09 0201 0 *                       ; Dropout Delay, 0 Second Tail
MPW 09 2211 0 *                       ; Dropout Message Time, 0 Seconds (default)
MPW 09 0202 0 *                       ; PTT Minimum Unkey Delay, 0 Second

MPW 09 0300 0 *                       ; Courtesy Delay, 0 Second
MPW 09 0301 0 *                       ; Dropout Delay, 0 Second Tail
MPW 09 2311 0 *                       ; Dropout Message Time, 0 Seconds (default)
MPW 09 0302 0 *                       ; PTT Minimum Unkey Delay, 0 Second
