You guys are moving the C73 capacitor over to connect the external antenna, right?

By "linksys" I guess you mean a dongle from an 802.11b,g router? Do they have the same connector as your Tmote? And are the connectors seated well? Also, you're sure you disabled the internal antenna? I think there's a capacitor that needs to be removed on the standard Tmotes. ...I guess I should try this sometime...
