I’ve just come across this incredible little backpacking SDR transceiver project. Not seen it mentioned on here so thought some of you might find this interesting.

Very interesting. Looks like the perfect SOTA activator rig!
We’ll see how much they’ll finally cost and how it works.
Thanks for sharing, Roger.

Looks good Roger, but I would be dubious about its dynamic range.
Display driver, signal processing, and direct sampling ADC/DAC in a STM32 is a tall order, it would be interesting to see how it handles QSK operation - lots of interrupts to juggle. Not much in the way of front end filtering either, which is typical.
Reminds me of SDRCube, Which is similar in architecture, although underdeveloped IMHO.
Could be promising though, it certainly will win on the power consumption front.
