   From QRZ.Com, the Icom handout, and Part 97 Of The FCC Rules -   
   Ham Radio Glossary - An overview of amateur radio terms.   
      
   PA   
   Power Amplifier   
      
   Packet   
   A digital mode that sends "packets" of data between stations. Since it   
   checks each packet received with what was sent, packet communications   
   are error free...what is sent is what is received. This can mean the   
   difference with traffic concerning 10 or 100 casualties. While there   
   are not as many packet bulletin board systems (PBBS's) now, as compared   
   to years ago, many hams still enjoy this mode of the hobby. It requires   
   a rig, a TNC, and a computer. VHF Packet typically is at 1200 baud, while   
   HF packet is at 300 baud.   
      
   Parawatch   
   See Dualwatch.   
      
   Paddles   
   Short for "Morse Code Key", one that contains small paddles that are   
   tapped in order to produce semi-automatic Morse Code (when connected to   
   a "keyer").   
      
   Part 97   
   Portion of the FCC rules relating to amateur radio.   
      
   Patch   
   Short for "Phone Patch".   
      
   PBT   
   Pass Band Tuning. A function electronically reducing interference by   
   narrowing IF bandwidth.   
      
   PEP   
   "Peak Envelope Power"; used to measure power output of an single sideband   
   signal. RF power at maximum amplitude.   
      
   Phone Patch   
   Device allowing audio from a telephone line to be placed in the audio   
   circuits of a transmitter/receiver (thanks to WD5CTQ).   
      
   Physician   
   For the purposes of the Part 97 Rules, a person who is licensed to practice   
   in a place where the amateur service is regulated by the FCC, as either a   
   Doctor of Medicine (MD) or a Doctor of Osteopathy (DO).   
      
   P-N Junction   
   A P-N junction (or N-P junction) is formed by creating two substrate   
   materials of P type and N type on a semiconductor. P type means it is   
   doped with "free holes" (electron depletion) and the N type is doped with   
   electrons. Of course by physics, the free holes and free electrons would   
   like to neutralize each other. A diode is formed with a P-N junction.   
   Basically, when you have a NPN transistor, you have two junctions ... an NP   
   junction between the collector and base, and a PN junction between the base   
   and emitter. Vice-versa with a PNP transistor. How you bias those junctions   
   controls how the transistor works.   
      
   Pink Ticket   
   FCC Notice of Rule Violation   
      
   PL   
   "Private Line", Motorola's trademarked name for CTCSS.   
      
   PLL   
   Phase Locked Loop. Circuit to synthesize the different frequencies a   
   radio will operate on.   
      
   PM   
   Phase Modulation or Pulse Modulation   
      
   Pocket Beep   
   Beeping function when a specific signal is received.   
      
   PNP   
   See "P-N Junction".   
      
   Priority Watch   
   Reception mode, which by a selected frequency is always periodically   
   checked when VFO is set to a different frequency.   
      
   PSK31   
   A digital mode which is rapidly growing in popularity; utilizes phase shift   
   keying (PSK) which is transmitted at 31 baud (speed). For more information,   
   please see http://www.psk31.org. While it does not have "error correction",   
   it can detect signals below the noise floor, using such programs as   
   DigiPan and MixW.   
      
   PTT   
   "Push to Talk"; a button on a microphone or on the side of a handheld radio   
   which activates the transmitter.
