Lee and the group, I remember there was a lot of traffic about add on speakers at one time. I use an MFJ "Clear Tone" speaker with my K2 (MFJ #MFJ - 281). This is very satisfactory for my needs (YMMV). I am nearly 100% CW, but it sounds OK on SSB too. Also recommended for FT 817 (not that anyone on this list has one of those ;-0) 73, Paul M0CDP K2 #2356 KX1 #231
