London ShortwaveThe PiZero 2W spectrum recorder runs for 7 hours on two 18650s & a step-down 5V converter (which doesn’t seem to add measurable noise on HF). And of course the batteries are hot-swappable as the unit has its own small UPS battery. The only limitation is the amount of free space on the MicroSD card 📡#PortableSDR #SDR #HF #Shortwave #SpectrumCapture #SpectrumRecording #AirSpy
1/4 Final version of the UI (for now). Battery indicator, remaining recording time available & the duration of the current recording (in hh:mm). The Pi boots into this UI and triggers airspyhf_rx to record with the selected parameters if a HF+ is connected. The screen has minimal 🔋 impact when sleeping.
