Advanced Configuration
• Soft-Carrier Dekey – Specifies how long (in ms) to wait after the removal of the keying
signal before actually dropping the transmitter’s carrier. The default setting is 0, but it may
be set to any value up to 255 ms. In most cases, no change is required from the default
setting. A possible exception is when the transceiver is inter-working with certain early-
generation MDS radio equipment.
• Push to Talk Signal – Specifies the sensing polarity of the PTT line. This must be
configured to one of the following values:
- Off – PTT line is not used.
- Hi – The PTT line is active-high.
