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.

NOTE: We are currently out of stock of Dummy Load kit PCBs This affects your order only if you included the optional dummy load. 

We are waiting for the new boards to arrive and we expect to be able to ship your order around mid-March 2019. Please be aware and accept that your whole order will wait for the availability of this item. 

 

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 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). 

Note: The QCX transceiver is always shipped with the latest firmware version available at the date of shipment.
