Welcome aboard Keiths' Teensy SDR builders group.

The Backpack SDR is an HF transceiver project that is based on the Teensy 4.0 or 4.1 MCU, the Teensy audio interface board and a few other off-the-shelf module to make a complete hf transceiver.  It uses as many off-the-shelf parts as it can in order to keep the build simple and also keep costs down. It’s not a budget build, per se, but the basic mono-band Backpack SDR can be built for under $200.

This group was established to be a single source of information on building and using this little SDR
HF transceiver, and to organize all the information better than could be done in the Facebook group.

To be in this group and build one of these for yourself, you will need a few skills... a good sense of humor, The ability to build electronic projects and maybe some programming skills .. but all are welcome!!! Please no posting links to commercial ads, or self promotion of your company . Please respect other members .. I have a big red button marked " BAN USER" I really don't want to exclude anybody, but I run 3 other forums and I know how to use it!!
