Hello Group, After seeing several messages about the D-104, I decided mine looked better in the shack than on the shelf in my study, so I spent some quality time with it this weekend.
It has the preamp built in the base, and the little schematic glued to the base is dated 9-75 which is about when I got it. Wiring it up was no problem and it seems to drive the K2 just fine, but I have a couple of questions. 1. There is a switch on the board labeled E and H. Can't for the life of me figure out why it is there. Seems to only switch one side of the push to talk switch from ground or the other push to talk line. So what's the E and H? 2. Has anyone tried running one of these off the K2 5V line available at the mic jack instead of the internal 9 V battery? VOX won't work as is because the preamp is switched in and out with the push to talk lever. Thanks in advance, 73, Tom, KJ3D (Formerly W3QS) _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
