Hello Thomas,
I noticed you have included the SDR# AM Co-channel Canceller in your blog, I’ve made a video of the SDR# FM Co-channel Canceller in action.Es IQ files are from August 2020, received using an Airspy HF+ Discovery using SDR# 1732, near Lobatse, Botswana. Playback
in SDR# 1772.
A couple of people asked me why the SDR# FM Co-Channel Canceller was only cancelling adjacent channel signals in my video above.
This video is for you:
FM Co-Channel Canceller separating two stations 60kHz apart on the OIRT FM band, received by Es in the UK:
Wow! This is simply amazing! Thank you for the demonstration Peter.
Again, the Co-Channel Canceller is a free upgrade for SDR# users.
Like I said before, this is revolutionary. Now that it (quite unexpectedly) works on FM too, I wonder if this would also work on SSB?
This sounds amazing!
I would like to try this out with files created with an Elad FDM-S2. I already tried, but with not very good success:
– A 1.5MHz (or bit more) mediumwave file loads ok but its center frequency is 0 (zero) and not even at the same place as it should be (it was 1130 kHz in the file but 999 whenp played with sdr# .1773).
– Starting playback of a 6 MHz FM file causes an immediate crach without any error codes.
Here’s another that is co-channel, from a 2019 Sporadic-E IQ WAV file.

Shouldn’t this be described as an adjacent channel canceller? Co-channel is when two stations are operating on the same frequency or channel.
Obviously you didn’t watch the second video.
