Despite some of the earlier FCD or RTL Dongles models having the capacity to tune on HF frequencies
 It does not mean that you will receive properly the HF signals.
Due the very poor IP3 of the front-end and nonexistence of filtering,

the tuner overloads with the intense signals from antenna.
This is why is impossible to receive seriously  HF Bands with "naked" SDR dongles
The HF-converter with is Double Balance Diode Ring mixer and Hi-Level LO,

makes a very rugged  front-end to deal with strong HF signals.
It´s still convenient to had a HF-converter on you SDR: The Reception on HF is clear, sensitive and selective.
As you can see on many videos posted worldwide by CT1FFU  HF-converters.
