The “QCX+” (QRP Labs Xcvr +): a feature-packed, high performance, single band 5W CW transceiver kit with WSPR beacon and built-in alignment and test equipment. Available for 80, 60, 40, 30, 20 or 17m bands. Experimental use on 15, 12, 10 or 6m (lower power output and reduced sensitivity). For complete details see http://qrp-labs.com/qcxp The Optional enclosure is black anodized…
The “QDX” (QRP Labs Digital Xcvr): a feature-packed, high performance, four-band (80, 40, 30, 20m) 5W Digi-modes transceiver kit, including embedded SDR receiver, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference. QDX transmits a SINGLE SIGNAL, it is not an SSB modulator with associated unwanted sideband and residual carrier, or intermodulation due to amplifier…
simple “digital” monoband transceiver SDT21 The goal of this project was the development of a simple to build CW monoband transceiver based on the direct superheterodyne principle with crystal control a la “PIXIE” or “Rockmite”, but with much better technical data. To minimize the circuit effort, the concept should be as highly integrated as possible…
X5105 is a highly portable transceiver working at HF+6m band, with a built-in power output of 5W. Technical features: Double-conversion superheterodyne, fitted with up to 3 lithium batteries of 18,650mph each. A standard main unit (embedded with one 8-pole 2.7k-SSB crystal filter) An optional high stability, high precision TCXO module An optional 500Hz narrow band…
eroStream Communications near Golden, Colorado entered the hobby radio market in 2013 with their revolutionary CommRadio CR-1 and follow up CR-1a SDR receivers. The success of these innovative radios left many asking for a transceiver of similar size and capability. The answer is the just announced CTX-10. The CommRadio CTX-10 blends high performance, internal SDR…
