Since I travel by car regularly and don't have XM or Sirius, I've found that using my Palm to receive an audio only broadcast for financial news, etc  is a great option. The signal is pretty steady so as long as I have coverage by cell tower but do have some problems.

I'm curious though, if an audio buffer was available and an Ultra low 'voice' oriented bit rate was used could I get fewer drop outs? I've found that current setting will only drop the bit rate to about 50kbps whereas I'm able to feed a WMA audio feed to my Treo tethered notebook computer at around 16kbps and almost never lose the audio. Thoughts?
