Assembled QCX+, aligned, tested and calibrated. With calibration certificate as pictured. Price includes $45 assembly fee. The assembly includes installation of the TCXO, AGC and/or Enclosure if you order these options. Some of the photos show the QCX+ installed in its optional enclosure.

NOTE: if you order the optional GPS, 50W amp, or Dummy load, these are in kit form, they are not assembled.  

NOTE: Assembled radios are built to order, the waiting list is published here - we ship around 25 per week therefore please accept some waiting time based on this; if you need it urgently then please contact us about it. 


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 160, 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 

Note: the optional QLG2 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). 

The optional TCXO gives very good frequency stability if you intend to use WSPR operation, where frequency drift is critical. It is highly recommended for WSPR operation, particularly if you are using a 17m or 20m radio.

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

QCX-series radios do not have AGC built-in. An AGC module is listed as an option.

NOTE: 18-Dec-2021: The ATmega328 chip is now unobtainable at any distributors, due to the global semiconductor shortage. We have managed to obtain stock to be able to continue offering this item, however, the price was very high and this has necessitated a temporary price increase of $2.79 which is currently included in the price of this item.
