S-COM 7K - Transmitter Unkey Delay

7K • Chapter 17
17-2
If a station can override the offending station and enter the Reset Transmitter
Timeout Timer command (on page 17-7), the transmitter will return to the air
and the timer will be reset. When the offending station releases his/her push-
to-talk button for at least one second (and no one has reset the timer for the
offending station), the timeout message will be sent again to inform him/her
that part of their transmission may have been lost.
Transmitter Unkey Delay
The Transmitter Unkey Delay holds the transmitter keyed for a programmable
period of time to prevent dropout between software keying requests. Event
macros can be defined that allow actions to occur at these events, eg. to
disable a CTCSS encoder before the transmitter is unkeyed (see page 17-14).
All the above delays and messages—as well as the transmitter timeout timer—
are fully programmable by the trustee. If, for example, the trustee does not
wish to have any courtesy delay or courtesy message, he/she may delete both.
In such case, the timer used for transmitter timeout timer will reset immediately
upon the user dropping his carrier. Figure 2 represents the Transmitter Tail
Sequence.
