I may have named this topic wrong, not sure. Is HFDL and HF-ACARS the same animal? This freq is for HFDL ARINC.

HFDL is very susceptible to a undesired tone on frequency, to the point of no decodes even for strong sigs.Ok thanks for that tip, never done HFDL before yet.
It looks like you have a fairly strong signal that is not HFDL in the passband, but I could be wrong.If you mean the signals up on 9350 and thereabouts, they were AM shortwave stations.
The sig in the pic you posted does not look like HFDL.Possible! Although I have never heard anything before on 8927 here. As this was around 3/4AM here, there was nothing running that would have been causing the noise.
You don't need 10MHz of spectrum displayed to copy HFDL.Not sure if this is a tip or a comment, I was only running 2 MHz at the time, which is typically what I run it at. Only deviate from that in the VHF aviation band, or when I am hunting stuff on VHF/UHF.
My RSP is set to use low IF and decimation 32 with a resultant spectrum width of 300KHz.
Those are very nice. Where's your QTH?
