If tough, dried-out roast beef haunts you in your dreams, you know the importance of not overcooking meat. The more beef cooks, the less succulent it becomes; quality declines most quickly past medium, or an internal temperature of 145 degrees Fahrenheit. That's the temperature recommended by the U.S. Department of Agriculture, but for juicy, rare roast beef, you can't cook it that much.
Automatic Packet Reporting System (APRS) is a digital communications system that uses packet radio technology to transmit information and text messages over amateur radio.
I should also say something about the Multiple Use Radio Service-MURS. This is an often overlooked service with lots of potential. Unlike the UHF GMRS/FRS (similar to the amateur 70 cm band), MURS is a VHF service, similar to the amateur 2 meter service. MURS radios are permitted up to 2 watts of power, and can use antennas which provide gain. The approximate frequency range of MURS is 150Mhz to 155Mhz on five channels.
