Rock Pi 4B : M.2 & USB 3.0 SBC

Rock Pi 4B single board computer review and demo, including testing a WD Black M.2 NVMe SSD in Debian, and media playback in Android. The video also shows the acrylic case, eMMC module, and large heat sink.

You can find more information on the Rock Pi 4 on its website here: http://rockpi.org/ and in the RADXA wiki here: https://wiki.radxa.com/Rockpi4

For NVMe and cooling tests, see my follow-up video here: https://www.youtube.com/watch?v=l6EUfqywsOI

This is not a sponsored video. However, the Rock Pi 4B featured was supplied for review by Allnet, who sell the board and its accessories here: https://shop.allnetchina.cn/ (outside Europe) and here: https://shop.allnet.de/search?sSearch=rockpi (inside Europe).

Quad band transceiver ZASTONE MP380+

Homebrew HF Vertical Antenna

This is the Cabela 16.5 Classic Crappie fishing pole. I used 1/4" copper tape as the conductor in each section.

SDR Receivers Comparison on VLF, LW and NDB band

SDR-Receivers Comparison on VLF, LW and NDB-band
*** Airspy HF , SDRplay RSP1A and ColibriNANO ***
In this video I am comparing three SDR-Receivers. I have made few recordings with every receiver with the same antenna and choose the best one (one with the best SNR = signal-to-noise ratio). My intention was to ensure the same conditions for all three SDR`s in order to make as fair as possible comparison. For example, I was set the frequency span displayed on the window to be as same as possible for all three receivers. The vertical axis for the signal stregth, was set to be equal (in decibels) too.Airspy HF and ColibriNANO was set to their minimum sample rate (48 kHz). RSP1A was set to minimum sample rate (2 MHz and 8 decimation).
No DSP enhancing on the SDR`s was used except APF (Audio peak filter) on ColibriNANO (I forgot to swith off).
