NOW FOR SALE: sBitx is a 40 watts, high performance SDR

Dear All,

The Developer’s Edition of the sBitx is finally for sale on Before you press the buy button, a few things to note.

1. HF Signals Corporation is now a USA company, registered in Delaware. As some of you know off-line, we are planning to increase our foot-print in the USA in the near future.

2. This is a developers edition, that means, there will be bugs. But nothing that can’t be fixed sooner than later by just running a simple “git pull” command from the command line. That said, the developer’s edition is meant for hackers and homebrewers. Do not purchase it if all you are interested in is a new radio with gee-whiz features. Let the developers get it first. We have limited stock.

3. We hope to bring the prices down as soon as the chip shortage eases. At the moment, we had to purchase the Raspberry Pis at $150 to ship these out.

4. The sBitx can be homebrewed by you. It is actually simpler that the ubitx, circuitry-wise. I will urge you to try brewing it yourself.

If you find any errors on the or‘s pages on sbitx, do write here on the group with #sbitxedits as the first word subject line. Others can skip it if they don’t want to read all that stuff.

Thanks for all the support and love.

  • Uses a hybrid superhet architecutre for high performance design
  • You can build it for less than $100 in new parts in addition to the Raspberry Pi and Display.
