It is ultra-affordable by being a single band radio with minimal parts and almost all pre-populated surface mount parts, which makes it easy to build. It uses an existing and well proven design, the uSDX, which suites these goals. **\u003c\/p\u003e\n\u003cp\u003ePebble HF is a low power QRP radio for morse code (CW), voice, and digital modes*. Pebble HF can output ~5W on battery power but can also output ~1W powered by USB, so that you can get started even without investing a special battery yet. Weighing less than 0.5 lbs (8oz), it is a great option for trying out portable radio.\u003c\/p\u003e\n\u003cp class=\"note\"\u003e* digital modes requires an external adapter.\u003c\/p\u003e\n\u003cp class=\"note\"\u003e** Pebble HF is an open source design based on the classic uSDX.

The backbone of Pebble HF is from Barb's hardware design and an existing firmware design by Guido PE1NNZ. Thank you so much to both of them!\u003c\/p\u003e\n\u003cp\u003eThis project is a day dream that Mike, N4FFF, has had since before becoming a ham. He got started in amateur radio with the believe that a cheap kit radio called the PIXIE is all he needed. He never was able to make a single contact on the PIXIE, but it was it's existance that allowed him to get started. The PIXIE's lack of filterning and tuning ended up being a problem he couldn't get passed. Now we are on a mission to make sure that a great option exists for anyone needting to get started!\u003c\/p\u003e\n\u003cp\u003eMike was introduced to Barb wb2cba by a viewer who was using his TinyDX QRPp radio for digital use. After a decade of actively looking for someone with the right experience, Barb's existing uSDX design was a perfect baseline. He modiied the design to make it ultra-affordable by making it a single band and, importantly, making as much of the design as possible surface mount so that it can be ordered super low cost. It is a brilliant design for this purpose because the base open source project is a software defined radio making it possible to pack a ton into a tiny package with super low cost!\u003c\/p\u003e\n\u003cp\u003eThere are many fantastic QPR radios already (\u003ca href=\"https:\/\/qrp-labs.com\/qmx.html\"\u003eQMX\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eand\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/hamgadgets.com\/cft1-by-km4cft.html\"\u003eCFT1\u003cspan\u003e \u003c\/span\u003e\u003c\/a\u003eare great examples).
