As of 14-May-2020, the QCX transceiver kit has been replaced by the new QCX+ kit http://shop.qrp-labs.com/qcxp
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.
Hard-copy assembly instructions are not included in the kit. You need to download the assembly and operating instructions manual from http://qrp-labs.com/qcx
Note: The QCX transceiver is always shipped with the latest firmware version available at the date of shipment.
Note: the optional GPS receiver module kit is very useful if you wish to operate this kit as a WSPR beacon (it disciplines frequency, time, and Maidenhead Locator grid square). It is also useful for calibrating the transceiver kit, to get the synthesiser reference oscillator precisely calibrated (resulting in accurate transmit/receive frequency).
An optional 50W PA kit is available, which also has an optional enclosure. This 50W PA kit will give your QCX an extra boost for those occasions when you need a bit more power - to work a particular station for a regular sked when conditions are bad; to deal with our bad band conditions these days; to work a particular DX staiton, etc etc. The 50W PA kit includes solid state Tx/Rx switching for full break-in (QSK) operation. The kit includes heatsinks and connectors as well as the PCB and all components. See http://qrp-labs.com/50wpa for more details.
