Thank you for mentioning the sigidwiki site, which is excellent.

I also use the ARTEMIS program, which is based on sigidwiki
and which I recommend for signal identification. It also incorporates a propagation dropdown
menu, which fetches data from NOAA.

I can alo recommend the other program on the Mark's Lab site: POSEIDON

I have forwarded this to the ARRL Official Observers.  This will help us to identify interfering signals.
Thank you for sharing this valuable resource.

When it comes to interference, ARRL seems to lack a lot of know how & info on RFI, maybe because they still think Analog TVI is still around by their old publications

A lot of new Digital HF devices & HF Interference devices out there, they ( ARRL  ) are simply in the dark about them.

HF Cable Modems, Frequency Hopping HF devices on HF, Control HF Motors
HF controlled Timers, SCADA HF, HF Alarm Systems, Hospital HF MRI Interference, Street Light Systems controlled via HF, In-Home HF Networks, HF Furnace/Cooling Systems, Internal Plant HF BPL LAN networks, etc 

Now most RFI interference is out of control and FCC & ARRL useless these days to find it! 

Hi ! Hi! 

These guys did not know what hit them

Old Timers !!
