Tv Broadcast signal`s

  • Server Issues.

    We are very aware that there have been system issues the past few days. In troubleshooting the system, it has been determined that the issue is at our provider and is hardware related. As of 12:05 PM ET our provider has moved us to a new server.

    Things seem to be running better on this new server. However in trying to diagnose the issue (before finding out it was a hardware issue) we made some system changes which we need to undo. So if you find any issues or errors please let us know in the Operations Center Forum.

    Thank you for your patience! Sorry for the issue!

Here is a chart of our US VHF-Low Channels:

This scan, using an RTL-SDR V3 dongle and GitHub RTLSDR Scanner software, shows the channel 3 Pilot Carrier:

As N5XZS mentioned in post #24, the rabbitears.info site can be very helpful in finding US VHF-Low channels. Start with this page first:

Allocation Map for Channel​

https://www.rabbitears.info/allocationmap.php

For all channel 2 allocations, fill it out like this, and click on Go:

The RTL-SDR V3 dongle SDR is available here (the V4 doesn't work with the Scanner):
Buy RTL-SDR Dongles (RTL2832U)

The RTLSDR Scanner software is available here:
Releases · EarToEarOak/RTLSDR-Scanner

I use version 1.3.0

There is a short tutorial by Pete Higgins:
OTA Signal Analyzers, Meters, Aimers, Bench Gear...

It took me 3 training sessions to learn how to use the Scanner software. If you also find it difficult to learn the Scanner software, you can use SDR# (SDRSharp) software instead with the V3 SDR. It will only show a little more than 2 MHz of the 6 MHz TV channel, but that is enough to show the low end of the channel to see the Pilot Carrier and estimate the SNR.
