uBITX -A compact HF transceiver
Applying the BITX philosophy (good performance out of absurdly cheap parts) to a multiband SSB radio. The trick here is using an Si oscillator chip that can provide three separate outputs -- so you can do things like switching sidebands by tweaking one oscillator either side of the final filter frequency. Very neat!
