How to Contact me...?
The most recommended way is via Twitter:@jr2khb.
The e-mail address: "[My Callsign] @ jarl.com" was already expired on Apr. 2019.
If you are QRZ.com user, the "messege" is possively available, but I could miss your messeges because I'm quite new to QRZ.com.
Another possible way is Facebook. If you are already registered as my "friend", you can send me messeges on "Messenger". I suppose this would be the most convinient way, but I have no idea whether you can contact to me if you are not my "friend".
