MOP (Meteor Observation Project) is a DOS- program, to detect radio meteors. The advantage compared to already existing programs for this use is that you don't have to build a special hardware-interface to connect your receiver with your computer. All you need to run this program is a PC (Pentium recommended), a SSB receiver for VHF, a 8 or 16Bit soundcard and, last but not least, a simple cable from your receiver to your soundcard.
