Priwet Alex! I believe you are referring to this picture posted by UN7GZ: http://forum.cqham.ru/download.php?id=32295 Was this W16 jumper cable completely missing or was it just poorly soldered? I also noticed some references on the list about the KXV3 RX ANT isolation problem. I assume you know this is covered on the K3 Enhancements and Application Notes page under "Receive Antenna TX Isolation Improvement (RXA Mod Kit for the KXV3)". This mod is not required for units with the KXV3 "Rev B" Main Board. http://www.elecraft.com/K3/k3_app_notes.htm 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/It-have-to-work-better%21-tp1572093p1572212.html Sent from the [K3] mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
