So has anyone using the k2/100 to drive a heathkit sb-200 linear? If so can
you give me some pointers on the interface to the amp? Still being new to the hobby would like some advice on the subject... __________ Dwight AI4II __________ _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Dwight,
I am going to use my SB-200 with the Elecraft. I have purchased an item called a "softkey" from Harbach Electronics. It is a board that mounts inside the SB-200 and essentially converts the high voltage keying line down to something the K2 can safely key. I haven't installed it yet...it requires a little rewiring to get it in the circuit. Trouble is, Harbach is shut down right now, I think due to a fire or something and Jeff is not taking any orders until he gets his place back in order. There are probably other options, but this is the one I chose because it designed specifically for, and wires in to, the circuitry of the SB-200.

Make sure the keying circuit is for positive voltage. Some of the keying
circuits I've seen for K2 are designed for negative voltage keying... the SB-200 is positive I believe. Larry N8LP Stan Rife wrote: >Dwight, > I am going to use my SB-200 with the Elecraft.

Here is a good interface that will work with the k2 and sb200. Particulars
