More info: Switchcraft #S760, Mouser part #502-S-760 Technical specs: ID .080" (2.03mm), assume 2.1mm OD .218" (5.5mm) See NOTE below Barrel Length .375" (9.52mm) Note: Switchcraft does not list a 5.1mm (0.20") diameter barrel coaxial power connector. It appears that ALL of their coaxial pwr connectors are 5.5mm (0.218") in diameter. I used a caliper to confirm the outside diameter of the barrel of the plug I'd received from Elecraft. 0.218" (5.5mm) on the button. For more info on this Switchcraft connector, go to: http://www.switchcraft.com/ and search for "S760". The plug dimension specs are at the bottom of this page, and if you click on selection #2 (760/S760) from the list at the top of the page, you can download a single-page PDF which shows to detailed engineering drawing of the plug, with references which will match to the specs on the page noted above. I believe this to be the power plug which we are using on our K2s and K1s. They ARE better quality than the plugs available from R/S, if for no other reason that the fact that the center cunductor of the Switchcraft plugs is slightly recessed within the insulator, thus making it more difficult to accidently short the positive lead to ground. The apparent R/S equivalent (at least with regard to dimensions, NOT quality) is their 274-1569 (5.5 x 2.1 mm). The apparent DigiKey part #'s are: Plug SC-1052-ND (as Ron has stated) Socket SC-1153-ND (the SC-1155-ND is SMT) NOTE that the 1998 DigiKey catalog from which I got this info had the Switchcraft part #'s for the plug and jack SWITCHED. However the DigiKey web site (www.digikey.com) had everything listed correctly. Users are urged to RETAIN this information for the future when you will surely need it. And WILL eventually need it... almost guaranteed!

Radio Shack Part #274-1569 for the 'inline' solder plug. They also have
an assortment of pre-wired cables and your choice of tips. Choose the 'M' tip. They have prewired 'Y's', extensions. Nice stuff, but don't expect anyone there at RS to know what you want or where to find it. Phrases like "I think it's in the PowerZone area" will get you to the right spot. The solder inline plugs are in a drawer, not hanging on the wall......All the other stuff is on the wall.

Note that R/S has a similar, but MUCH LOWER QUALITY connector. Generally,
their connectors allow the center contact to protrude enough that it could, conceivably, short out to some thing metal. The Switchcraft connectors have the center contact recessed a bit, making shorts MUCH less probably. 73, Tom _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
