+      <para>Some receivers are equipped with special wide band receiver which is intended

+      Calling that ioctl with (1) will enable it, and with (0) disable it.
+      This might be useful of receivers that have otherwise narrow band receiver
+      that prevents them to be used with some remotes.
+      Wide band receiver might also be more precise
+      On the other hand its disadvantage it usually reduced range of reception.
+      Note: wide band receiver might be implictly enabled if you enable
+      carrier reports. In that case it will be disabled as soon as you disable
+      carrier reports. Trying to disable wide band receiver while carrier
+      reports are active will do nothing.</para>
