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]
The Lincolnshire Poacher was a powerful British shortwave numbers station that transmitted from HM Government Communications Centre near Gawcott in Buckinghamshire, England, [1] and later from Cyprus, from the mid-1960s to July 2008.

Although not the first software-defined radio on the market, the IC-7300 was the first mass-produced mainstream amateur radio to use SDR technology instead of the older PLL-based transceiver design. [4] Designed to replace the older IC-746PRO the IC-7300 is smaller and significantly lighter than its predecessor. [5]
LPD433 (low power device 433 MHz) is a UHF band in which license free communication devices are allowed to operate in some regions. The frequencies correspond with the ITU region 1 ISM band of 433.050 MHz to 434.790 MHz.
