Occupied-bandwidth measurements #
These are historical engineering measurements from 27 September 2026, made against OpenJSQ source revision 444a626f. They are not a new 1.1.0 radio test or a legal determination about where a mode may be transmitted.

The complete CSV records the profile, bearer, FEC, nominal audio center, 99% occupied bandwidth and audio edges, together with the analysis resolution and frame count. The numbers were computed from rendered waveform samples, not measured at a radio's antenna connector. They do not include later transmitter filtering, deviation or propagation effects.
obw99_hz is the width containing 99% of the analyzed power. obw99_lower_hz and obw99_upper_hz are its audio edges; the offset columns are relative to the nominal center. bw26db_hz is a different bandwidth measure and must not be substituted for obw99_hz.
The CSV retains the original names and values, including off-ladder FSQ profiles used in the experiment. A row in the experiment does not mean that profile is offered by a current build. The JG25 specification cites this snapshot for its native profile widths.
Use with the current documentation #
Read the JG25 specification, FSQ specification, and modem descriptions for supported formats and operating limits. The operator remains responsible for the radio setup, emission bandwidth, licence privileges and applicable rules; see the licence agreement. These figures alone do not establish regulatory compliance.
