Ed, The Elecraft BL1 can be built for either the 4:1 or 1:1 configuration. Alternately, the BL2 uses a switch to change from a 1:1 ratio to 4:1.
If that is physically too big for you, use the same design as either the BL1 or BL2 and wind it on the binocular core used in the K2 PA output (Elecraft PN E690011) - in that case, the enclosure will be one of your choosing (I suggest non-metallic to eliminate sneak paths that are not obvious on casual inspection). 73, Don W3FPR On 11/5/2012 10:54 AM, Ed Ketterer wrote: > I'm looking for a small 4:1 QRP balun to use with my KX3 (hence, it needs > only 10 watt power capability).
