Some older versions, try them with HDSDR but the setup will be different from what I describe. There is a version here I have not tried this. may be found in Sodira (Note this has embedded DRM, this makes DRM easy but some prefer Dream) and in other, earlier, compilations of Dream. Read the legal information on the Sourceforge pages. This version is at Sourceforge but note the need to compile (or find) libfaad2 dll for it to decode audio. May 2014, there are later versions here Be aware different versions may not all behave in the same way. I have used version 1.17qt4 for my description, it is easiest to setup. Multiband support, continuously tunable through bands 160m-10m (and from 20kHz.This is one of the digimodes where one does not need VAC when used with a soundcard-based receiver, like a SoftRock.
SSB opposite side-band/carrier suppression transmit: better than -45dBc, IMD3 (two-tone) -33dBc, Receive: better than -50dBc DSP features: Automatic Gain Control (AGC), Noise-reduction (NR), Voice-triggered Xmit (VOX), RX Attenuators (ATT), TX noise gate, TX drive control, Volume control, dBm/S-meter Approximately 5W PEP SSB output from 13.8V supply Simple, fun and versatile QRP SSB HF transceiver with embedded DSP and SDR functions Use original genuine LM4562 or LM833 op amp chip Use original genuine Omron magnetic latching relay All LPF parts use 100V C0G/NP0 capacitors Rich interfaces (CAT, PTT OUT, MIC/KEY, K-head microphone) Independent core board and RF board to avoid own signal interference.
High-precision for KDS brand TCXO, frequency accuracy is better than 1PPM, frequency stability is better than 0.5PPM High emission efficiency, 80m/60m/40m/30m/20m efficiency is higher than 85%, 17m/15m efficiency is higher than 80%, 10m efficiency is higher than 70% Can reach 3-5W power in 8 bands and reserve TO-220 package pads required for upgrades Excellent PCB layout design in line with high-frequency circuit design principles to ensure excellent performance Support to connect to PC and use FT8, JS8, FT4 and other digital mode software control, support CW automatic decoding. It adopts 1602N LCD screen, built-in speakers. The ultra-small size makes it easy to carry for outdoor use. This is a shortwave QRP SSB/CW transceiver. USDR is optimized and modified based on the open source work uSDX/QCX-SSB. USDR SDR Transceiver All Mode 8 Band HF Ham Radio QRP CW Transceiver 80M/60M/40M/30M/20M/17M/15M/10M
