Using the SUP-2400 Downconverter with an LNA and RTL-SDR to Receive 2.4 GHz Video

Earlier in June YouTube user T3CHNOTURK posted a video demonstrating him receiving signals above the maximum 1.7 GHz range of the RTL-SDR by using a modified SUP-2400 downconverter. Back in April it was discovered by KD0CQ that a $5 DirecTV SUP-2400 circuit could be modified and turned into a downconverter for use with the RTL-SDR.

Now T3CHNOTURK has uploaded a new video showing more demonstrations of the RTL-SDR + SUP-2400 combo in action. This time he adds a PGA-103 based LNA to boost the signal strength, which gives him better effective range. In the video he shows reception of a wireless keyboard once again, and then goes on to show him receiving 2.4 GHz analog PAL video using the RTL-SDR program TVSharp. The picture is not particularly clear, but it is a decent demonstration.

Watching a VHS Tape using a RTL-SDR

Over on YouTube user DogsRNiceMineCraft has uploaded a video showing a VHS tape being played using an RTL-SDR. To do this he connected the RF out port on his VHS tape player by wrapping the RTL-SDR stock antenna cord around the RF out cable from the VCR. He then used the TV Sharp software to view the VHS tape.

The playback quality is very poor, but the concept works!

TVSharp Updated to Version 1.2

The PAL/NTSC analogue TV viewer TVSharp has recently been updated to version 1.2. This new version features an updated GUI as well as automatic frequency correction and automatic position correction. This may correct some of the scrolling and slanting problems seen in previous versions.

The latest TVSharp can be downloaded from here.

Word of warning: Chrome recognizes the download as malicious, however I have downloaded the file using FireFox and scanned it with Microsoft Security Essentials which found it to be clean.
