BladeRF 2.0 USB 3.0 Software Defined Radio Launched for $480 and Up

BladeRF 2.0 Micro

Around 5 years ago, several affordable FPGA based open source software defined radio boards launched including HackRF, BladeRF x40 / x115, and  USRP B200. The company behind BladeRF has now launched an update of their boards with Blade RF 2.0 coming in two versions namely bladeRF 2.0 micro xA4 and bladeRF 2.0 micro xA9 supporting the same 47MHz to 6GHz frequency range, and 61.44MHz sampling rate, but the latter comes with a more powerful 301KLE Cyclone V FPGA. BladeRF 2.0 hardware specifications: FPGA Micro xA4 – Intel / Altera Cyclone V FPGA with 49 kLE Micro xA9 – Intel / Altera Cyclone V FPGA with 301 kLE Analog Devices RF Transceiver 47 MHz to 6 GHz frequency range 2×2 MIMO, 61.44 MHz sampling rate 56 MHz filtered bandwidth (IBW) Automatic gain control (AGC) Real- time custom gain control tables controlled via SPI and discrete external input pins Automatic IQ and […]

$43 Mecool M8S Plus DVB is an Entry Level Android Set-Top Box with DVB-T2/T/C Tuner

Android set-top boxes with tuner usually costs $70 and up depending on hardware specifications, and number of tuners, but if you want something cheap that runs Android and supports DVB-T2, “Mecool M8S Plus DVB” may be worth looking at, since it’s sold for just $55.99 shipped. [Update: Mecool M8S Plus DVB can now be found on Banggood for $42.99 including shipping] In order to achieve such low price, the company had to make some compromises, and the TV box only comes with 1GB RAM, and 8GB storage.  Amlogic however recently published a press release about their “new Amlogic S905X chipset” supporting Netflix and 1GB RAM. S905X is clearly not new, but it’s possible the company made some Android optimizations for their S9XX SoC family that provides a decent user experience even with just 1GB RAM. Mecool M8S Plus DVB set-top-box specifications: SoC –  Amlogic S905D quad core ARM Cortex-A53 processor […]

VideoStrong Introduces Low Cost Version of KI Plus T2 S2 Hybrid Android TV Box with Amlogic S805X Processor

VideoStrong K1 Plus T2/S2 is an Android 5.1 set-top-box with DVB-S/S2 and DVB-T/T2 tuner that was launched roughly two years ago with Amlogic S905 quad core processor. Since then, the company has now launched variant of the model with Amlogic S912 (e.g. KIII Pro hybrid TV box)  or Amlogic S905D (e.g. KI Pro set-top box) processors. But now, provided the information on Alibaba is correct, the company has launched a new version of KI Plus T2/S2 with Amlogic S805X which should be cheaper, run a more recent Android 7.1 operating system, at the cost of losing support for 4K decoding, since the processor only support Full HD (1080p60) decoding at most. Since the company updated an existing product, some specific details are wrong on Alibaba, but KI Plus T2 S2 (2018) specifications should be as follows: SoC –  Amlogic S805X quad core ARM Cortex-A53 @ up to 1.2 GHz with […]

Building a Compact Digital TV Transmitter with Raspberry Pi Zero, Pi Camera, and LimeSDR Mini USB SDR Board

There are few affordable standalone systems that allow you to transmit video over the air, and back in 2016, I had the chance to check out V-Bridge Muses-β MPEG-2/-4 encoder and DTV modular taking HDMI or composite video input. It was easy to use and worked fine, but it would still cost close to $600, and might have been a little smaller. Evariste Okcestbon has now created its own digital TV transmitter prototype, combining LimeSDR Mini USB SDR board with Raspberry Pi Zero board, and instead of supporting external input from HDMI or AV ports, he used an official Pi camera for video, and was able to transmit the video over a 1.2 GHz connection to a Raspberry Pi 2 with an RTL-SDR dongle, with the Pi 2 board also taking care of displaying the video signal.   The full flow of transmission can be summarized as follows: Video from […]

Geniatech ATV598Max is a Certified Android TV Hybrid TV Box with ATSC, DVB-T2, DVB-C, or ISDB-T Digital TV Tuner

Geniatech ATV495 Max was the first model from the company to get official Android TV certifications. There now a bunch of those ATV OEM devices, but if you want one with a digital TV tuner, then the choice is much more limited, and so far, I only heard about ARRIS set top boxes. Geniatech ATV598 Max can now be added to the list, as the company informed me the Amlogic quad core hybrid TV box with ATSC, DVB-T2, or DVB-C tuner had just received official Android TV certification from Google too. ATV598Max specifications: SoC  – Amlogic S905D quad core Arm Cortex-A53 processor up to 1.5 GHz with penta-core Mali-450MP GPU System Memory – 2GB DDR3 (optional 1GB) Storage – 16GB eMMC flash + micro SD slot up to 32GB Video Output – HDMI 2.0a; Audio – Via HDMI, optical output, optional Dolby support Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi […]

Mecool KII Pro Set-Top-Box Upgraded to Amlogic S905D Processor, Android 7.1.2

VideoStrong is making some of the most popular – at least on this website – Android set-box boxes with digital TV tuner on the market with products like Mecool KIII Pro, or KI Pro, mostly because of their affordability. Software may be hit or miss depending on your local requirement (e.g. AC3 on DVB-T2, language encoding issues, etc..), so there’s fairly large number of users and some community tools or firmware such as DVB Channel Editor or Vitmos OS that may make them better devices. Most models are based on Amlogic S905 or S912, but Amlogic launched S905D processor some time ago with better tuner support (multiple demodulator support) which for example allowing me to watch terrestrial TV (DVB-T2) while recording satellite TV (DVB-S2) on Sen5 TV box. VideoStrong decided to upgrade their KII Pro Android set-top box  with S905 processor, DVB-T2/T/C and DVB-S2/S tuners to the new Amlogic S905D […]

How to Use Khadas VIM2 Board with VTV Expansion DTV Board as a Live TV Streaming Server

Khadas-VIM2-Heatsink

Khadas VIM2 is the first and only Amlogic S912 based hobbyist development board on the market, which makes it interesting by itself, but the company also added some interesting features such as an SPI flash for network boot, Wake-on-LAN support, and more. Last month the company sent me a sample of the Khadas VIM2 Basic (2GB RAM/16GB flash) together with VTV Extension DTV Board featuring a DVB-T2/C and DVB-S2 tuner. I’ve already checkout the hardware and shown how to assemble the kit, so for the second part of the review it seemed like a good idea to use the board as a Live TV streaming server broadcasting satellite, cable or terrestrial TV to devices connected to the local network. At first I wanted to use Linux operating system, because I could have run other Linux server services, but SuperDVB, the company that makes and supports the tuner board, only have […]
