Apply a correction of RF carrier frequency. This is a method to compensate deviation of the frequency due to production faults, extreme temperatures and crystal resonator ageing.
Represented in kHz. Range: from -30 up to 30.
Most likely that you don't need to change anything here. This page contains measured frequency deviation of different radio modules been used.

A 128-bit hexadecimal key that is in use to encrypt an aircraft position information. This feature is designed to ensure secure data transfer through OGN network toward FAI server while FAI/IGC Category 1 sport event is taking place.
Use a key provided by your gliding contest organizer.
Read IGC secure flight data trackers document for more information.
This feature is available since Release 1.1.
It is applicable for certain hardware platforms only:
- ESP32, ESP32-S3, ESP32-C3 and ESP32-C6
- nRF52840
- CC1352R and CC1312R
- RP2040
- STM32WLE5
- RA4M1
Access to the hexadecimal key on the ESP32-XX is provided through WebUI. For other platforms one should use NMEA command line method.
ATTENTION: Use of wrong key will make your device ignored by both air traffic and OGN ground stations. If you are uncertain - leave the key value to stay 00000000000000000000000000000000 (i.e. no encryption) all the time.
21 - this setting is applicable for OGNTP radio protocol only ;
Below is an illustration of default settings for SoftRF firmware version 1.0
To backup your settings - take a screenshot of the WebUI or SoftRF Tool settings page.
To restore your settings - manually set all necessary selectors, buttons and knobs of the WebUI or SoftRF Tool settings page while using earlier saved screenshot as a reference.
