A Pocket DATV Transmitter and Receiver with Raspberry Pi, LimeSDR Mini and RTL-SDR

Over on YouTube user Evariste Okcestbon has uploaded a video showing his simple pocket DATV system that consists of a LimeSDR running on a Raspberry Pi Zero transmitting live camera images via DATV which is received by an RTL-SDR running on a Raspberry Pi 3.

If you didn't already know, DATV stands for Digital Amateur Television and is a digital mode somewhat similar to digital over the air TV signals that can be used by hams for transmitting their own TV signals on the ham bands. The LimeSDR Mini is a $139 US transmit and receive capable SDR that is currently crowdfunding and available for pre-order on Crowdsupply. It is expected to ship at the end of February 2018.

Evariste uses a range of software packages on each Raspberry Pi. He writes the following in the video description:

Description of a minimal Digital Tv chain : Transmitter and Receiver.

Hardware used on Tx : PiZero,Picam,LimeSDR Mini

Hardware used on Rx : Raspberry Pi 2, RTL-SDR,Monitor

Software used on Tx : avc2ts,dvb2iq,limetx

Software used on Rx : rtl_sdr,leandvb,kisspectrum,ts2es,hello_video

Special Thx to G4GUO, F4DAV and LimeSDR

Evariste is also the author of Rpidatv which allows you to transmit DATV directly from the GPIO pins of a Raspberry Pi without the need for any transmit capable SDR.

Mr Okcestbon is a very skilled programmer! I have been following him and I’m truly amazed how cool his software is. I could never do such things. Mere mortals need not apply.

It seems to me that comments are dropping off here. Thank You Google reCAPTCHA! This is probably my last comment for a long while (if ever) until the Google reCAPTCHA nonsense with its layers and layers of scripting spy crap is removed 🙁
