Transmit Inhibit; Maximum Transmit Time; Front Panel Display For 25 Khz And 8.33 Khz Channel Spacing - Park Air T6M User Manual

Transmit Inhibit

Any frequency programmed into the radio can be made 'receive only'. To achieve this, the transmit
function on the channel is always inhibited, or the transmit facility can be inhibited only when the channel
is busy. If warning sounds have been set, a warning is heard when an attempt is made to key the
transmitter.

Maximum Transmit Time

A maximum continuous transmit time can be programmed into the radio's personality. The options are:
No limit.
q
A limit that can be set between 30 and 300 seconds.
q
If a limit has been set, and warning sounds have been set, the radio produces warning beeps
q
10 seconds before the transmission time expires.

FRONT PANEL DISPLAY FOR 25 kHz AND 8.33 kHz CHANNEL SPACING

When selecting an 8.33 kHz channel frequency, the displayed frequency differs from the actual channel
frequency. Table 1 on page 27 shows the pattern used for 25 kHz and 8.33 kHz spaced channel
frequencies from 118.0000 MHz to 118.1916 MHz. The pattern is the same for any frequency within the
radio's frequency range. The display conforms to ICAO convention for 8.33 kHz operation.
Note that operation using 8.33 kHz channel spacing within the USA is not currently allowed under FCC
regulations.
