Dear Gene, I found one Pohancsek in the Hungarian phonebook:
Bíróné Pohancsek Mónika 1108 Budapest, Bányató utca 6 3. em. 15. +3612627965 I think, it is not too big investment to write her a letter, you can use the English. If your information about Zoltán Pohancsek is good, try to ask the museum of the Hungarian Radio about him: email@example.com Have a nice result! Everytime be mind to the European polite forms... Lajos Reich, Budapest.
