   From QRZ.Com, the Icom handout, and Part 97 Of The FCC Rules -   
   Ham Radio Glossary - An overview of amateur radio terms.   
      
   Radio Regulations   
   The latest ITU Radio Regulations to which the United States is a party.   
       
   RACES   
   (radio amateur civil emergency service). A radio service using amateur   
   stations for civil defense communications during periods of local,   
   regional or national civil emergencies.   
       
   Reflected power   
   Non-radiated power dissipated as heat when the transmitter is mismatched   
   to the antenna or load.   
      
   Rain locker   
   Slang for a bathroom shower.   
      
   Remote control   
   The use of a control operator who indirectly manipulates the operating   
   adjustments in the station through a control link to achieve compliance   
   with the FCC Rules.   
       
   Repeater   
   A system consisting of at least one transmitter, one receiver, and a   
   controller, which receives a signal on one frequency and retransmits it   
   on another frequency. Repeaters are typically located in high locations   
   so that they have greater coverage area. They greatly increase a user's   
   communication range since they can retransmit his/her signal across all   
   of its coverage area. Repeaters are in geographically high locations,   
   and are most commonly used on the 2 meter and 70 centimeter bands. See   
   also "Simplex Repeater".   
      
   RF   
   "Radio Frequency"; typically used as slang for "Radio Frequency Energy".   
      
   RF Burn   
   A painful sensation felt when coming into direct contact with RF energy;   
   can be dangerous when experienced with high levels of RF power.   
      
   RF ground   
   Connection of amateur radio equipment to earth ground to eliminate   
   hazards from RF exposure and reduce RFI.   
      
   RFI   
   Radio Frequency Interference   
      
   Rig   
   Slang for Radio   
      
   RIT   
   "Receive Incremental Tuning"; a common feature on HF radios that allows the   
   user to slightly change the receive frequency while leaving the transmit   
   frequency the same.   
      
   RST   
   "Readability, Strength, Tone"; a system by which a received signal quality   
   is graded, and a signal report is given. "Readability" is judged on a   
   scale from 1 to 5, and "Strength" and "Tone" are judged on a scale from   
   1 to 9. "Tone" does not apply to a "phone" (voice) signal. A very high   
   quality CW signal is "599" (pronounced "five nine nine"), and such a phone   
   signal is "59" (pronounced "five nine").   
      
   RTTY   
   "Radio Teletype"; popular digital mode on HF   
      
   Rubber Duck   
   Also known as "Rubber Duckie", a flexible antenna normally found on   
   hand-held tranceivers. Inefficient, but useable, and they don't poke you in   
   the ribs too badly either! (thanks to WD5CTQ).   
      
   RX   
   Abbreviation for "receiver" or "receive".
