title: Firefox OS WebFM API - LF or MF
body: <p>The <a href="https://developer.mozilla.org/en-US/docs/Web/API/FMRadio" rel="nofollow"><strong>WebFM API</strong></a> provides access to the device FM radio. </p>
  
  <p>You can set the frequency with <code>FMRadio.setFrequency()</code>.</p>
  
  <p>Does the WebFM API for Firefox OS support <code>LF</code> and <code>MF</code> too, or does it only work with <code>VHF</code>?</p>
  
  <pre><code> - LF   Low Frequency        30–300 kHz
   - MF   Medium Frequency     0,3–3  MHz
   - VHF  Very High Frequency  30–300 MHz
  </code></pre>
  
  <p>Unfortunately, the specification at MDN is not clear enough.</p>
