Troubleshooting TV Reception with Spektrum and an RTL-SDR

Thank you to "Double A" for submitting his latest YouTube tutorial video that shows how to use an RTL-SDR together with the Spektrum software to optimize TV reception by comparing TV antennas, repositioning antennas and detecting interference.

Double A's video first shows how to setup the RTL-SDR and how to install and use the Spektrum analyzer software. He then compares a popular highly rated phased array TV antenna against cheaper log periodic TV antenna, with the results showing that the phased array works a lot better at most TV frequencies even with accurate positioning. He goes on to show how he scans for FM, 5G and local electronics interference and the effect of an FM filter can help.

This was an excellent video. RTL-SDR dongles were originally designed for Over The Air TV reception in areas such as Europe, Africa, etc., so using one as a tool to compare TV antennas is a great idea. In addition, the dongle that Double A is using can receive from about 25 mHz – 1700 mHz in all modes (AM, FM, SSB, CW) and can be used to listen to police, fire, marine, NOAA weather and other utilities.
Great job Double A.


This software hasn’t been updated in more than 3 years….anyone have any recent experience with it?
