I believe that some K3's later than S/N 211 do not have the HAGC mod. Mine is S/N 222. While installing the KPA3 yesterday I checked the area of the mod and it looks exactly like the pictures of the unmodded board. The resistor that was changed to a LED looks just like all the other resistors, the two resistors that are shorted look just like resistors, and there is no added resistor linking two points. So unless the changes made in production were done in such a way that the board still looks the same, I must assume my K3 does not have the mod, and possibly others post S/N 211 haven't either. ----- Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com Zerobeat Ham Forums: www.zerobeat.net/smf -- View this message in context: http://www.nabble.com/K3-noise-blanker-tp17338480p17368032.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
