7. Modem Setup
There are two menu options available to fine tune the YagTracker modem for use
with any VHF or UHF FM transceiver. The modem is capable of receive and transmit
1200 baud data. The connections can be made through the microphone and external
speaker connections and are fairly forgiving. It’s a good idea to fine tune the settings for
proper deviation and and receive amp gain.
a. Transmit Audio
● The transmit audio is controlled through the menu shown above. The settings
are in dB. Rotate the rotary encoder to set the level. Pressing the rotary switch
in will activate several functions. These functions are activated in a cycle of three
total clicks:
1. One Click -
Force Transmit, no tones
2. Two Clicks -
Force Transmit, with 1200 Hz tone
3. Three Clicks -
Force Transmit, with 2200 Hz tone
● While in the third click function, a fourth click will dekey the transmitter and return
you back to the idle state.
●
While in transmit, the rotary encoder can be turned to set the level. It’s ideal to
monitor your transmitter deviation at the same time, if possible.
●
Once the setting has been completed, use the Beacon/Escape button to exit out
of the menu.
