2026.5.1 - Field Release III / 2026

This release features a new explicit tuner-bandwidth setting and reporting of SDR metrics, allowing for better configuration in challenging settings.

Added

• tuner-bandwidth parameter to customize configuration (defaulting to twice the sample rate)
• SDR metrics reporting (peak, rms, snr) for better local configuration

Full Changelog: 2026.4.1...2026.5.1

2026.4.1 - Field Release II / 2026

This release is tested with 1.2 MHz sampling rate an 1024 FFT size on Raspberry Pi 4-based vhf:trackers. Beware that the signal threshold cannot be set to low, as this increases load and might lead to resource extinction.

Added

• ringbuffer for SDR data to achieve io / cpu - decoupling

Changed

• radiotracking now runs without bash wrapper and with high priority (Nice=-10)
• reduce image size through removed pycache files
• Update-files for pre- and stable releases
• Using tsOS-base 2026.4.1

Fixed

• Hang-Ups could occur in SDR termination

2025.4.1 - Field Release II/2025 (w/ vga_gain fix)

This release is the first one to be called tsOS-vhf!

Features:

• Using rtlsdr fork: https://github.com/librtlsdr/librtlsdr
  • Fixed gain stage settings for R802T tuners: lna_gain, mixer_gain, vga_gain
  • PLL now locks correctly
• tsOS-base update:
  • Configuration of timezone via bootfs
  • WittyPi update
  • authorized_keys via bootfs

Fix:

• Termination status was updated with tz-naive TS, which leads to cbor error.
• vga_gain default is now 7
