[aprssig] A New "Space" Trend ?

[KB5ILY - Travis W. Burton]

Maybe I haven't noticed it in the past, but I have noticed several new stations 
inserting a space between CALL and an SSID.  Plus the SSID is one or two 
letters rather than numbers.  Only one example of this in my stations list 
would be:
NT5RN A
NT5RN B
NT5RN C
NT5RN AB
NT5RN-B
NT5RN-C

Is space a valid character per the spec ?
