The core modules of the project are the Atlas passive backplane, the Ozy interface which provides a USB 2.0 data channel between the HPSDR system and the host PC, and the Mercury and Penelope receiver and exciter boards, which use high speed ADCs and DACs for direct conversion of received or transmitted signals in the DC to 55 MHz frequency range.
The TS-820 did not have an LED frequency counter, but was otherwise identical to the 820S. [33] The TS-820S was the most sophisticated (and common) variant. [ 33 ] The TS-820X, unavailable in the United States, was primarily produced in Japan.
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]

M17 uses Frequency-Division Multiple Access (FDMA) technology in which different communication streams are separated by frequency and run concurrently. It utilizes 4,800 symbols per second, 4-level frequency-shift keying (4FSK) with a root Nyquist filter applied to the bitstream. Radio channels are 9 kHz wide, with channel spacing of 12.5 kHz.
