Locally broadcast your cell phone through FM band using MAX2606 from Maxim:

This design idea presents an integrated IF voltage-controlled oscillator (VCO) that can retransmit the audio signal from a cell phone to the FM broadcast band. By placing the cell phone’s speaker near the microphone, the user can use the phone as a hands-free device while driving.

The light weight, compact size and low cost DSA800 family of spectrum analyzers from Rigol Technologies feature digital IF technology to provide the reliability and performance necessary for RF applications. The spectrum analyzers have a frequency range of 9 kHz to 1.5 GHz with a typical displayed average noise level (DANL) of ‑135 dBm. SSB offset phase noise is typically -80 dBc/Hz at 10 kHz, and the resolution bandwidth is adjustable from 100 Hz to 1 MHz. A preamplifier and AM/FM demodulation are standard with this instrument.
