Be a part of the future with a prototype kit build of the RFBitBanger, a low-power high-frequency digital radio by Dr. Daniel Marks KW4TI. Presented by Open Research Institute, this kit is designed to produce 4 watts of power and opens up a new digital protocol called SCAMP. Your donation in exchange for this kit directly enables the development of an innovative Class E amplifier based radio design. It has a display, button menu navigation, and keyboard connection for keyboard modes and keyboard-enabled navigation. This radio can be taken portable or used in a case. If you have a 3d printer, then Dr. Marks has a design ready for you to print.
* Built-in digital modes: CW, RTTY, SCAMP (FSK and OOK, multiple speeds)
* Key jack supports straight keys and iambic paddles
* Open Source hardware and firmware, Arduino UNO compatible https://github.com/profdc9/RFBitBanger
* External sound-card FSK digital modes supported (including FT4/FT8)
* Experimental SSB support
* Serial port support (2400 baud) for send and receive in keyboard modes
SCAMP is a new protocol that allows keyboard-to-keyboard contacts with a digital protocol that has excellent connection performance. See Dr. Marks presentation about RFBitBanger at QSO Today Academy in September 2023 to learn more about SCAMP and the RFBitBanger project.

Updated 27 August 2023 from 3 bandpass filters provided to 12 bandpass filter boards provided, with enough parts to build 9.
All surface mount parts on the main board are pre-installed at the factory. All the through-hole parts you need to complete the radio are provided for you to solder yourself. If you don’t know how to wind toroids or solder surface mount capacitors, this is an excellent kit to learn on. There are just six toroids on the main board, and two on each band pass filter board. You can build just one band pass filter board and operate on a single band, or you can build an assortment. We provide 12 filter boards, enough toroids to build any 9 filters, and a supply of capacitors that will let you build those 9 filters for 9 different HF ham bands. These capacitors are size 1206, which is the largest common size for SMT capacitors and the easiest to solder manually. All you’ll need is a pair of tweezers and your regular soldering iron and solder. We provide detailed instructions on winding the toroids and soldering the capacitors. You get spare filter boards to experiment with.
Support is provided through a dedicated Open Research Institute Slack channel.

Delivery is no earlier than late August 2023. Will be posted here and on the ORI website at https://www.openresearch.institute/rfbitbanger-project/
