This is a case for a super inexpensive amateur radio 40m transceiver, the Pixie. The case is for a specific variant of the Pixie, available from quite a number of different China sources for a few dollars, such as http://www.banggood.com/DIY-Radio-40M-CW-Shortwave-Transmitter-Kit-Receiver-7_023-7_026MHz-p-973111.html

Note that there are many Pixie variants, and versions other than exactly the one shown will probably not fit.

For the history of the Pixie, see http://www.al7fs.us/AL7FS2.html There is more info on the Chinese Pixie version here: http://kb2hsh.blogspot.no/2014/12/the-chinese-pixie-2-qrp-transceiver.html

The Pixie needs an antenna, a power source, a headphone and a telegraphy key.

Ideally, the Pixie is best served by a proper shielded metal case, of course.

I found out the issue. You have the V3 PCB and my new ones are the V 4.3. It has the Piezo on board and does not have the BNC bulkhead connector on the board (although I will put the BNC's in the enclosure}. The spacing for the earphone and key jacks is about the millimeter or two different. It is also necessary on the old board, to bend the Xtal to fit in the enclosure but reducing the height of the corner mounts can solve that.
I think the the key is a nice addition as well as the battery holder.


If I can ever learn how to modify it, I would make it wider to accommodate a 9 volt battery. That would make it nice and portable to go to the field with


Have a look at this design, it includes room for a battery, and has a primitive morse key built in as well: http://www.thingiverse.com/thing:870953

I like the case. I did find that the openings for the key and ear phones are a bit too wide. I don't know if it is the version of the Pixie that I have or not. In any event I will have to learn to use a program to modify that. I can also make the openings a bit smaller to get a snugger fit.

Thanks for your work


Not entirely sure how you mean, they did fit my Pixie fairly well, which used a 3.5 mm plug and a BNC. There is a bit of room around the openings to allow for tolerances.

I'll print another one. I am still new at this, and maybe I did something wrong in the set up. I'll let you know how I make out

Nice case, thanks for the design. What is the difference between the top, and the top_trim?

top_trim has a hole giving access to the trimpot.
