The ACOM team, are proud to introduce the brand new 2020S. Solid-State 1500 W: 1.8-54 MHz Linear Power Amplifier with Touch-Screen Remote Control.
The amplifier employs two powerful modules in power splitting/combining technique which is well time-proven in high-power commercial applications to provide sufficient output headroom. Thanks to input and output ports isolation from each other, the intermodulation...
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 extruded...
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 non-linearity....
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 and realizable without hand-wound coils....
