New RTL-SDR Blog dongle - HF via direct sampling, software switchable bias tee

New RTL-SDR Blog dongles with HF via direct sampling are now available for order, here is the short version of the biggest changes :

1) HF support via direct sampling. Connect an HF antenna directly to the SMA connector and tune from 500 kHz – 24 MHz with the direct sampling mod. (No hardware modding or soldering required)

2) Lower internal noise. Less spurs, lower noise floor etc.

3) Software switchable bias tee. No need to do any soldering to enable the bias tee. Can be turned on and off in software.
