FM RDS Broadcaster & RF Jammer

A Raspberry Pi RDS FM transmitter plus a simulated jamming study.

01 · The problem

Analyze RF interference and spectrum-allocation behavior defensively.

02 · Approach

  1. 1

    Broadcast on a vacant 434 MHz channel using PiFmAdv (RDS).

  2. 2

    Transmitted carrier noise via gr-osmosdr on an SDR terminal.

  3. 3

    Recorded and analyzed signal degradation.

03 · Outcome

Demonstrated spectrum-allocation and defensive-jamming concepts.
