TXDELAY(1)              XR32 REFERENCE MANUAL                19/1/2013

COMMAND
        TXDELAY -- Display / Set the transmit keyup delay for a port.

SYNOPSIS
        TXD[ELAY] <port> [millisecs]

AVAILABILITY
        Sysop-only.

DESCRIPTION
        The TXDELAY command allows the value of the transmit keyup
        delay for a port to be displayed or altered. This is the
        interval between the transmitter being keyed up and the
        start of a transmitted packet. (see NOTES).

        Any changes made by this command override the settings
        specified in the PORT sections of XROUTER.CFG, and remain in
        force only until XR32 restarts.

OPTIONS
        If a single numeric argument is supplied, the current value
        for that port number is displayed.

        If two numeric arguments are supplied, the first specifies the
        port number, and the second specifies the new value for the
        parameter in milliseconds.

EXAMPLE
        TXDELAY 3       - Display current setting for port 3
        TXDELAY 3 300   - Set port 3 txdelay to 300 millisecs

NOTES
        TXDELAY is the interval between the transmitter being keyed up
        and the start of a transmitted packet.  It allows time for the
        RF to reach its full value, and for the TX audio circuits to
        stabilise.  Some synthesised rigs require a large txdelay (500
        or more) to allow the synthesiser to swing between RX and TX
        frequencies, and many rigs have audio stages which take 100 ms
        to stabilise while oversized electrolytics charge up.

        One factor which is often overlooked is the other end's
        receiver.  It takes a finite time for the squelch to open, and
        if the rig has just been transmitting it may take a while to
        stabilise back to receiving, especially with synthesised rigs.

        If your txd is too short, you will be sending replies before
        the other end is ready to hear you, and unnecessary retries
        will result.

        On KISS TNC's, you should allow up to 5 minutes for any new
        setting to take effect.
