Thanks to Van Norman Audio Visual, ROC has a fantastic Public Address system, with lots of speakers positioned all along the flag line at the front of the range.  However, even with all these speakers, it's not always possible to hear the LCO announcements over the PA system when you're far out on the range recovering your project, or out loading a rocket on the "away" pads.  Also, if you're parked several rows back in the camping area, you may not always be able to hear the PA system clearly.

For these reasons, ROC will be broadcasting all PA system announcements throughout LDRS 29 at 90.1 MHz on your FM radio dial.

The ROC Radio broadcasts make use of a low-power FCC-legal FM radio transmitter, on a normally-empty channel, providing radio coverage to the entire launch site.  Simply tune your car radio or other receiver to 90.1 MHz on your FM dial, and you should be able to hear everything going on.
