PrepComm MMX TearDown
The MMX Multi-band Morse Code Transceiver is the evolution of the DMX-40+ Morse Code Transceiver,and includes the keyboard! It has the same industry-leading decoder, the same high sensitive SDR receiver, 10 frequency memories per band, RPL microprogramming for custom automation, and more. However, what is added is a band board plug-in system that supports up to 3 bands. Currently, the supported bands include 80, 40, and 20 meters. You can purchase a single band MMX, and add other bands later, purchase a dual band MMX, and add the third band later, or even get all three bands on your initial order!
Specifications are similar to the DMX-40+, such as receiver sensitivity of -119 dBm. Power output is highest on 40 meter, and slightly lower on 80 and 20 meter bands, as listed in the Specifications tab in the right column.
