How about an ultra-portable "QCX mini" version? #qcx

Torbjorn Skauli

Hans, I don't think you will have time for this, but here is a suggestion: I sympathize with the thread discussing the larger size of the QCX+. Given the quality of the QCX, many will want the radio more than the building of it. How about a "QCX mini" where the majority of components are pre-installed SMD, on a smaller PCB than the original? The design could aim for minimum size to achieve an affordable true pocket size HF rig. The builder could add only the band-specific parts, and other parts that would be costly to pre-assemble, and an enclosure of his choice. Controls could be installed on a break-off part of the PCB for flexibility in enclosure design. This version could also be more accessible to beginners since it will have far fewer parts to install. Apart from the effort to redo the design (again), hopefully the economics could work out through simpler logistics, smaller board area, lower component cost, and an expanded market?

I say this based on my own experience with the original QCX, which I have fitted into a rater cramped minimum-size 3D-printed enclosure with battery and paddle ( This rig, and a wire dipole, actually fit in the pockets of my jacket. I have been able to use my QCX in odd time slots and spaces such as flight departure halls and family outings, and thereby actually get on the air in a busy life. The favourite location is on the top of the local ski jump, the destination of my exercise bike ride, with an "inverted vertical" wire antenna suspended from the tower in the picture (loaded by a pinecone in the end). From here, the QCX WSPR beacon has hit seven continents (and G0UPL) in half an hour.

I am sure many people will want to have these possibilities in pocket size, at the price point of the QCX, and with only a minimum of assembly to do. For my part, I would certainly want one, and would be happy to design an even smaller 3D-printable enclosure for it.

After the QSX is finished, perhaps, Hans?

Anyway, thanks for all the fun,
