Notes: This parameter is mandatory if using APRS with a ‘Fixed Location’.
TX Freq [MHz]
The frequency specified with this parameter for analog APRS is totally
independent of the selected channels frequency. The APRS beacon is transmitted
using 1200 Baud AFSK. The frequency data within the following table is subject to
change without prior notice.

TX QT/DQT
It may be required to setup CTCSS or DCS whenever transmitting your position on
analog APRS to a repeater or iGate
. This parameter is normally ‘off’ (no CTCSS/DCS
used), but may be assigned any of the supported CTCSS frequencies or DCS/DCS-
I values. See Appendix A for supported CTCSS frequencies and DCS/DCS-I values.
Default: Off
