New from QRPGuys: 40/30/20m DSB Digital Transceiver II Kit!
https://qrpguys.com/qrpguys-dsb-digital-transceiver2 (https://qrpguys.com/qrpguys-dsb-digital-transceiver2)
The new QRPGuys DSB Digital Transceiver II is a low cost, multiband, DSB transceiver kit, with three easy plug-in modules for 40/30/20m, (additional module pcb’s available). Changes that Steve Weber (KD1JV) have included are, a high pass filter to help with BCB interference in troubled environments, replaced the relay with solid state switching, and designed a multi-band 160m-17m VFO as an easy plug-in option. The transceiver output remains the same at an approximate 2.5 watts on 40m, over 1.5 watts on 30m, and over 1 watt on 20m. The receiver sensitivity was measured at .4uV (-115dBm). The board is the same size, and all the components are included for the transceiver (3.0″ x 3.12″) and three band modules, for 40/30/20m
