I worked KH2T in March 2003, and sent QSL with sufficient postage to
JL1EAN's address at qrz.com in September 2003. Then, I sent a second
QSL to the KH2T address on qrz.com in February this year. Next, I
tried emailing JL1EAN but I did not receive a response using any known
email address of JL1EAN.

Does someone know, how to get in touch with JL1EAN or did his mail
address change recently?

Thank you for any hint,

73! Uli, KK8I
