   From QRZ.Com, the Icom handout, and Part 97 Of The FCC Rules -   
   Ham Radio Glossary - An overview of amateur radio terms.   
      
   m. Meters.   
      
   Machine   
   Slang for "repeater", and sometimes for rig.

   Matchbox   
   A device placed between a transmitter and an antenna to tune the circuit   
   to resonance. Normally called an Antenna Tuner (thanks to WD5CTQ).   
      
   Mc   
   "Megacycle"; equivalent to MHz; regarded as an "old fashioned" way of   
   describing frequency.   
      
   Medfer   
   One who experiments with radio communications at low frequencies such as   
   those on the edges of the AM broadcast band (under FCC Part 15).   
      
   Memory bank   
   A set of memory channels organized into a group.   
      
   Memory effect   
   Rechargeable batteries such as Ni-Cad (Nickel Cadmium) and Ni-MH   
   (Nickel Metal Hydride) types may be temporarlity getting less   
   capacity/usage as a result of repeated non-full charge/discharge   
   cycles. It is called so sinc rechargeable batteries lose capcity   
   as if "memorize" wrong full capacity level at less than full charge.   
   Li-ion (Lithium Ion) batteries are free from this effect.   
      
   Message forwarding system   
   A group of amateur stations participating in a voluntary, cooperative,   
   interactive arrangement where communications are sent from the control   
   operator of an originating station to the control operator of one or   
   more destination stations by one or more forwarding stations.   
      
   MF   
   (medium frequency). The frequency range 300-3000 kHz.   
      
   MHz   
   See Hz   
      
   MIC   
   Microphone   
      
   Modulation   
   Method of adding information to a radio frequency carrier.   
      
   MPR   
   "Mass Produced Rig"; a radio which is produced in large quantities; often   
   used to describe radios that are NOT originally purchased in "kit" form.   
      
   MUF   
   "Maximum Useable Frequency"; that frequency above which expected   
   propagation no longer exists.
