Last week when in Bhutan, I met Pradhan, A51PN, who was very active from 1972 to 1983 when he worked in the Wireless Dept of the Bhutan government. He gave me his stack of log books to digitize and upload to LOTW, about 30,000 estimated contacts. Pradhan is now 73 and in good health and living a quiet retired life.
I will be able to answer QSL requests for anyone needing a card for A51PN. He has meticulous notes in his logs about QSLs that were returned.
