I'd like to see somebody create a similar type of site that caters specifically to scanner listeners, who may be submitting tropo DX manually from VHF / UHF / 700 / 800. These APRS maps depend upon APRS digipeaters, and obviously those same maps are only taking into account what is being heard on 144.39. If we had someplace where sensible people who can identify tropo events can submit what they are hearing (and from what location they heard it from), especially on higher bands, it could be somewhat useful to the hobby. Of course, the whole idea for using APRS for this is because the mapping can be totally automated. But I've always thought that it would be nice for scanner listeners (who like to DX) to be able to submit confirmed tropo DX on scanner bands that they are hearing, which in turn might encourage others to actually pull out their Pro96Com / Unitrunker / DSDPlus and start sniffing for DX if they happen to see a duct over their area.
