Description

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.

MAP65 can accept input signals directly from a soundcard capable of sampling at 96000 samples per second. Two soundcard channels (one "stereo" channel) are required for a single polarization system, and four channels for dual polarization. Optionally, Linrad (by SM5BSZ) or SDR-Radio (by HB9DRV) can be used as convenient and highly effective "front ends" between receiver hardware and MAP65's data input. Linrad offers extremely effective noise-blanking capabilities, especially when strong signals are present in the receiver passband. SDR-Radio offers user-friendly control of supported receiver hardware, as well as many useful and attractive displays.

On the receive side, the following hardware and software combinations are known to work well with MAP65:

WSE with Linrad or direct input from 4-channel soundcard

IQ+ with Linrad or direct input from 4-channel soundcard

SDR-IQ, other RFspace radios, or Perseus with Linrad or SDR-Radio

FUNcube Dongle with Linrad, SDR-Radio, or direct USB input

SoftRock or similar with Linrad, SDR-Radio, or direct input from 2-channel soundcard
