The QCX mini is a high-performance single band HF QRP CW transceiver kit available for just $55 with a 50W amp for an additional $29.50.
My QCX Mini kit from Hans Summers QRP Labs arrived just before Christmas and was sitting under the Christmas tree for me to open. I’ll be documenting the journey with some links to other useful sites along the way. Watch this space!
Made sure to install the IC holder as far to the top of the PCB as possible to ensure sufficient space for the paddle socket and the TCXO board.
Now for a nice cup of coffee before alignment this evening
Alignment now done, no issues (once I had fixed a dodgy soldering joint on the TCXO!). I followed Hans’ video here: (117) Tuning up your QCX+ – YouTube
Initial findings are that it’s receiving very well and RF output at 12V is just a shade over 3W.
Having a Bud to celebrate progress so far!
Transmit test to follow …
Testing the Mini QCX in WSPR TX mode:
My very first transmission tests on WSPR:
And the results – AMAZING – Decoded in Antractica on first transmission, how excellent is that for something that was a bag of components 2 days ago!
Received on both receivers at DP0GVN – Neumayer Station III
Ekstroem Ice Shelf, Atka Bay, Dronning Maud Land, Antarctica
Top 50 spots, all over 1000Km in less than 10min (note only ONE station is reporting drift). Ignore the power shown as 5W, it’s actually 3.6W!:
… and also DP0POL/MM the German Ice-breaker Maritime Mobile (at this very moment the Polarstern, a German research icebreaker is presently off the coast of Africa en route to the scientific station in Antarctica. )
Time to play with CW I think …
No reply to CQ call but picked up on the reverse beacon network in USA and Russia.
Now to bed … Looking forward to some CW QSO’s tomorrow 🙂 Anyone for a QCX to QCX sked?
I am going to put further WSPR posts here: https://m0icr.com/category/wspr
First CW QSO on QCX Mini – Willi DL2IAD
Very pleased to report working Willi DL2IAD (Herschweiler-Pettersheim, Germany) this morning on the QCX Mini. 599 both ways, a solid QSO. Exactly 600Km IO91SO <> JN39QL.
Second QSO on QCX mini GM4ENF 489 (Al in in Cupar, Fife, Scotland)
Boxed up and finished! ( ….. for now!)
A few minutes in the New Year’s Day German AGCW contest on 40m using the Mini QCX

In the build I will be following some of the useful tips by Ryan Flowers (including his YouTube videos), link here: https://miscdotgeek.com/
I’ve just noticed that David Casler (Excellent YouTube channel by the way) has just received his QCX Mini and will be describing his build here: (117) The QCX-Mini 20m QRP Rig Kit Arrives (#342) – YouTube)
