Update on my faulty uSDX "white button" from Banggood.
Trying to get Banggood to take the faulty radio back didn't go too well. but eventually they offered me 51 quid, half the purchase price. I accepted because by then I had uploaded some new firmware and cleaned up some terrible soldering. I intended to add some photos of the soldering into this video but ran out of time. Now running GW8RDI's V4.00 via GitHub and the radio is performing so well and providing great fun. Basically turned a poorly constructed sdr into a great little bit of kit. The tr uSDX is great too and worked straight out of the box it has to be said.
