==== Apogee Lockout
- Apogee lockout is the number of seconds after boost
+ Apogee lockout is the number of seconds after launch
where the flight computer will not fire the apogee
charge, even if the rocket appears to be at
apogee. This is often called 'Mach Delay', as it is
pressure increase, and so this setting should be left
at the default value of zero to disable it.
+ [WARNING]
+ Firmware versions older than 1.8.6 have a
+ bug which resets the time since launch to zero each
+ time a motor starts burning. Update firmware to get
+ the correct behavior.

-==== Frequency
-
- This configures which of the frequencies to use for
- both telemetry and packet command mode. Note that if
- you set this value via packet command mode, the
- TeleDongle frequency will also be automatically
- reconfigured to match so that communication will
- continue afterwards.
-
-==== RF Calibration
-
- The radios in every Altus Metrum device are calibrated
- at the factory to ensure that they transmit and
- receive on the specified frequency. If you need to
- you can adjust the calibration by changing this value.
- Do not do this without understanding what the value
- means, read the appendix on calibration and/or the
- source code for more information. To change a
- TeleDongle's calibration, you must reprogram the unit
- completely.
-
-==== Telemetry/RDF/APRS Enable
-
- Enables the radio for transmission during
- flight. When disabled, the radio will not
- transmit anything during flight at all.
-
-==== Telemetry baud rate
-
- This sets the modulation bit rate for data
- transmission for both telemetry and packet
- link mode. Lower bit rates will increase range
- while reducing the amount of data that can be
- sent and increasing battery consumption. All
- telemetry is done using a rate 1/2 constraint
- 4 convolution code, so the actual data
- transmission rate is 1/2 of the modulation bit
- rate specified here.
-
-==== APRS Interval
-
- How often to transmit GPS information via APRS
- (in seconds). When set to zero, APRS
- transmission is disabled.
- ifdef::altusmetrum[]
- This option is
- available on TeleMetrum v2 and TeleMega
- boards. TeleMetrum v1 boards cannot transmit
- APRS packets.
- endif::altusmetrum[]
- Note that a single APRS packet
- takes nearly a full second to transmit, so
- enabling this option will prevent sending any
- other telemetry during that time.
-
-==== APRS SSID
-
- Which SSID to report in APRS packets. By
- default, this is set to the last digit of the
- serial number, but can be configured to any
- value from 0 to 9.
-
-==== APRS Format
-
- Whether to send APRS data in Compressed or
- Uncompressed format. Compressed format is
- smaller and more precise. Uncompressed
- format is older, but may work better with your
- device. The Kenwood TH-D72 only displays
- altitude information with Uncompressed
- format, while the Yaesu FT1D only displays
- altitude with Compressed format. Test before
- you fly to see which to use.
-
-==== Callsign
-
- This sets the call sign included in each
- telemetry packet. Set this as needed to
- conform to your local radio regulations.
