I finished building and installing the KAT2 in K2 #1521. It tunes my half sized G5RV on all bands just fine (I had QSOs into Colorado and Cuba on 15m ssb today). With the installed KSB2 & KBT2, #1521 is ready for portable/hfpack operations. Now, if only Spring would come here to NYC! 73 de Mike, W2VD
