Sample rate asked	5 Msps
Lowest working rate	4.608 Msps
Channel width	1.728 MHz

OnAir takes any frequency you type; the numbers above are the mode's starting point and the range its table describes. In the app the shortcut label is DECT cordless phones and base stations on the ten carriers 1881.792....

What OnAir shows

Base stations from their beacons: RFPI with the manufacturer code and system number, level, slots used, system-information tails, a burst log with base and handset bursts. Activity and signalling only: calls are encrypted, the voice is not decoded and nothing is sent.

Tips and caveats

• Checked with generated signals and impairments; recordings of real signals welcome.
• Which radio: No: this mode needs a radio that samples at 4.608 Msps or more, and an RTL-SDR reaches about 2.4 Msps.
• Try it without a radio: most modes include a built-in synthetic test signal, so you can open the screen and try the controls first.
• Receiving and the law: This mode is passive. It only receives, never connects, pairs or joins networks, and never decrypts payloads. Check the rules where you live. See Legal.
