Meters. Machine Slang for "repeater", and sometimes for rig. MARS Military Affiliate Radio Service 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. --- SBBSecho 3.14-Win32 * Origin: The Thunderbolt BBS - Little Rock, Arkansas (1:2320/33) SEEN-BY: 1/19 120 123 15/0 16/0 18/0 19/10 37 50/109 90/1 105/81 106/201 SEEN-BY: 116/17 18 116 123/0 10 25 130 131 170 180 200 525 755 3001 SEEN-BY: 135/300 142/104 153/7715 154/10 30 40 50 700 203/0 218/700 SEEN-BY: 220/90 221/1 6 360 222/2 226/18 30 227/114 229/110 112 113 SEEN-BY: 229/206 307 317 424 426 428 470 664 700 240/1120 1200 5832 SEEN-BY: 250/1 266/512 275/1000 280/5003 282/1038 299/6 301/1 113 SEEN-BY: 317/3 320/119 219 319 2119 322/0 757 335/364 341/66 342/200 SEEN-BY: 396/45 423/81 460/58 467/888 633/280 712/848 1321 2320/0 SEEN-BY: 2320/33 105 304 401 3634/0 12 27 56 57 119 4500/1 5001/100 SEEN-BY: 5005/49 5020/715 1042 4441 5030/49 5054/8 5058/104 5064/56 SEEN-BY: 5075/128 5083/1 444 5090/958 PATH: 2320/33 105 154/10 3634/12 5020/1042 301/1 221/6 1 320/219 PATH: 229/426 |
