The LD-1TR is a general-coverage, 100 kHz – 30 MHz, USB-controlled 5-Watt transceiver (transmit enabled on Amateur bands only) intended for Radio Amateurs. Its low cost and high performance (comparable to a typical Amateur-grade receiver, such as an FT-817) make it a great addition to any ham shack. Small in size, it is also ideal for portable operation using a notebook computer. It does require a host computer, either desktop or notebook (not a netbook) with Windows XP, Vista or Windows 7 and a souncard with a stereo line-in connector. Transmitting requires a second soundcard. It also requires SDR signal-processing software, available to downloadfrom several third-parties (HDSDR is recommended) at no cost.Power output is at nominally 5 Watts on the 160 through 10 meter bands, slightly higher (as much as 7 Watts) on some bands and slightly less (but at least 4 Watts) on the others. Available modes depend on the SDR software, but generally include AM, CW and SSB, plus digital modes using additional software.
