Anyone have the TinySA Ultra? I purchased one recently and it's real handy in the radio shack as it's a spectrum analyzer and signal generator. Has a four inch screen, rechargeable battery, receives up into the several GHz range, has a demodulator (you can use it as a rudimentary receiver), SD card to save traces, can be self calibrated and can fit in your shirt pocket for portable use. Cost $149 when I purchased it. As a ham for almost a half-century and a radio tinker for over 60 years this has got to be one of the most inexpensive and useful pieces of equipment I've seen.
