Yes, 433.800 is a backup APRS frequency in Europe. Main and the most used is 
I think 433.800 in Europe could be used for APRS as alternative 144.990 
freq. in the US.
Talking about APRS in Europe, do you know how many countries adopted new 
WIDEn-n standards? In Poland we do not have any more TRACEn-n or TRACE. Just 
WIDEn-n and SPn-n, in addition we still keep RELAY and WIDE for continental 
compatibility. Not many information about SSn-n in other European countries.
