MAP65 works together with suitable hardware that converts RF to baseband. The hardware/software combination implements a wideband, highly optimized receiver for the JT65 protocol, with matching transmitting features using a standard SSB transceiver. MAP65 can be used in both single-polarization and dual-polarization systems. If two polarization channels are available, MAP65 determines and matches the linear polarization angle of each decodable signal. This capability provides a major advantage for efficient EME ("Moonbounce") communication on the 144 and 432 MHz bands. A single-channel system works extremely well for 23 cm EME, displaying all signals (both CW and JT65) in the sub-band 1296.000 to 1296.090 MHz and decoding the JT65 signals.
