This RTL-SDR has inside a USB dongle soldered to main PCB which contains also a low band filter for HF input. The dongle is based on RTL2832U and R820T2. There is no converter for HF band, the HF connector is rather connected to Q input of RTL2832U. Suggested software for Windows is old and without HF (0-30 MHz) support. I tested the receiver with software GPRX on Linux. It works well, both VHF/UHF and HF. However, HF configuration is rather tricky: set Device to "Other..." and Device string to "rtl=0,direct_samp=4". As it is my first RTL-SDR, I can't compare parameters with other products. The appearance looks very cheap: the AL case is overlaid with printed paper.
