JUMMAX Green Mini RTL2832U R820T DVB-T SDR DAB FM USB DIGITAL TV Tuner Receiver RTL-SDR Project + DAB dongle Tuner 25MHz-1700MHz
- Spuer mini Realtek RTL2832U & R820T USB DVB-T Receiver Tuner
- Fit for RTL-SDR Project DVB-T Tuning Range
- Runteck Original DVB-T FM + DAB
- Up for sale is based on the R820T (can be the replacement of E4000)tuner IC made by Rafael Mirco
- Chip is R820T, the frequency range 25-1000MHz

complex samples. This has the benefit of having no DC offset spike in
the middle of the spectrum.
So far the tuner dr
