RTL SDR Dongle vs Kenwood TS 480 on 14 MHz SSB [00:10:04]

Visit my web page for more information: http://www.qsl.net/z33t
RTL-SDR dongle plus Up-Converter vs Kenwood TS-480 comparison on (HF) 14 MHz SSB.

It is very interesting to see how RTL-SDR dongle (which cost only (7) seven USA dollars) is capable to receive the same weak signals on HF like excellent modern and much better Kenwood TS-480 transceiver.

RTL-SDR dongle can receive from 24 to 1750 MHz (all modes AM, FM, SSB, LSB, USB, DSB, CW...)
In order to receive on lower frequencies (VLF, LF and HF) have to connect Up-Conoverter (which cost about 40 - 50 USA dollars).

Using up-converter is much better than using RTL-SDR in direct sampling mode (without up-converter).

The antenna in this video is Delta Loop, 43.2 meters long.
No DSP on both radios is used. Receiving bandwidth is 2.4 kHz, standard for SSB.

Despite the fact that The RTL-SDR dongle has only 8 bit ADC (Analog to Digital Converter) which limits its dynamic range to about 50 - 60 dB, It is a good performer comparing to much better Kenwood TS-480.
Moreover, in this video I have chosen the receiving signals to be in the middle of the strong signals during the WAE DX SSB Contest. And yet, "little boy" performed amazingly brilliant.

RTL-SDR dongle has unbeatable price/quality ratio on the planet, that is for sure!
