Q: How can I disable my transmitter PTT?

The controller supports control of the transmitter PTT using software switches.  Disabling a transmitter PTT will cause the PTT front panel LED to flash when the transmitter would normally key.  Here are macros for enabling and disabling transmitter #1 PTT:

; 6140*, Port Control: Transmitter PTT Disable
MPW 20 6140 DD 63 0112 0 *              ; TX1 PTT Disable
MPW 29 6140 DD 63 0113 0 *              ; TX1 Untimed Unkey

; 6141*, Port Control: Transmitter PTT Enable
MPW 20 6141 DD 63 0112 1 *              ; TX1 PTT Enable
MPW 29 6141 DD 63 0113 0 *              ; TX1 Untimed Unkey

Sometimes you want to turn off a receiver that is feeding one or more paths.  In version 3.3.1 and newer versions of the firmware, there are new Receiver Enable/Disable Software Switches.  Disabling a receiver will cause the COR and CTCSS front panel LEDs to flash.  Here are macros that disable receiver #1 COR and PTT inputs:

; 6150*, Port Control: Receiver Access Disabled To All Paths
MPW 20 6150 DD 63 0119 0 *              ; Set Receiver Disabled
MPW 29 6150 DD 15 999310 9960 0339 0001 0314 * ; Say "Receiver 1 OFF"

; 6151*, Port Control: Receiver Access Enabled To All Paths
MPW 20 6151 DD 63 0119 1 *              ; Set Receiver Enabled
MPW 29 6151 DD 15 999310 9960 0339 0001 0315 * ; Say "Receiver 1 ON"
Sometimes you want to disable an entire port so that the receiver is also inactive.  Here are macros for that that make use of the macros above:
; 6101*, Port Control: Enable Port, Both RX and TX
MPW 20 6101 6141 *                      ; Transmitter PTT Enable
MPW 29 6101 6151 *                      ; Receiver Access Enable

; 6102*, Port Control: Disable Port, Both RX and TX
MPW 20 6102 6140 *                      ; Transmitter PTT Disable
MPW 29 6102 6150 *                      ; Receiver Access Disable
You can change the macro names as you like.  Note that these macros use the Macro-Only Password.  You'll need to turn on that feature with the following command:
; Enable/Disable Macro-Only Password Decoding
MPW 63 0004 1 *                         ; Enabled (disabled, default)
