Yes, although it isn't clear whom. It isn't K1TTT is being fed with this 
stuff. It may be something to do with (feeds to) the internet spotting 
services.

It appears likely that someone somewhere (in the EU) is using Windows 
number handling routines is not coping well with decimal numbers using 
'.' rather than ',' as the decimal point.

It is also true that AR-C has a rewritten version that has very recently 
appeared in the wild and there may some problems with some/one of the EU 
stations that use it. But it could easily be caused by yet another spot 
sucker that someone has written.

This was a deliberate policy decision many years ago. One of the main 
drivers for me to write it was the VHF/UHF community in the UK. They 
felt that AK1A did not address their needs. One of which was the ability 
to spot things like Russian VHF TV, FM radio etc to enable them to 
monitor possible tropo / E openings.

I don't believe I have seen such spots for many years now, but they did 
happen in the beginning.

BTW The problem seems to have subsided now (16h45 Sunday)
