Receiving “TOO” instead of “599” is not uncommon. I’ve always thought it was 
because a SHIFT was lost in either transmission or reception.

If you look at the International Telegraphy Alphabet No. 2 (Baudot-Murray code 
or ITA2)  you’ll see that the 5 & T are the same, except for the Letters Shift 
and the Figures Shift. The same goes for 9 & O.  If he was sending you a 599 
(which is faster than 5NN in RTTY) the shift was lost and you received a TOO.  
The same thing probably happened when he sent OH.  Dropped the Letters Shift on 
the O and you received a 9.
