How can I get email address or otherwise contact ham in Russia? (02-Aug-26)

I'm trying get in touch with RZ4HD in Russia (Yuri Chmykhun) as I'd like to discuss a thread he started on qrz.ru (in the VHFDX forum there) in 2021 (he is/was working on application of a type of now-obsolete LDMOS FET that I'm interested in using). Yuri's QRZ entry has no email contact information.

I tried registering with qrz.ru (which hosts the VHFDX forum) so that I could join the discussion (which returned to life recently) --- my meager 1970s-era high school russian helped a little, and I eventually found that I could not register there as qrz.ru does not accept email addresses lacking .ru domain (my email address domain is yahoo.com)

Subject line of this posting is (I hope) reasonably self-explanatory, so any advice and/or help in getting Internet contact with RZ4HD would be much appreciated (including any suggestions on where among qrz I should ask this question!)

Might P.O.Box 88, Moscow still work?

 

I sent you a private message but it's under mod review.
It may be subject to error but it looks right.

 

His postal address is here on QRZ. Its formatted weirdly but you should be able to figure it out.
