11.10. Tuning and Diagnostics

Access the tuning and diagnostics screen with the 'Tuning/Diagnostics' button.
From this screen, you can exercise the tracker hardware and set the audio level.
The top row of buttons controls the red and green elements of the ACT LED, the
PTT output, and the power relay, and the second row allows AFSK tones to be
sent, either with or without PTT on. When both tone buttons are on, the tracker
sends alternating mark/space tones at the specified baud rate. The 'Sensors' pane
shows the raw readings from the on-board sensors. The temperature reading is
shown without the calibration constant applied.
Use the RX Gain setting and your radio's volume adjustment to keep the
received audio level (indicated by the blue bar) between 50% and 100% of full
scale when the radio is receiving a packet.
