Alexey, Make that change IF AND ONLY IF 1) you will never install the KSB2, AND 2) you will not operate above the 5 watt level.
That change makes the K2 PA transistors more efficient at 5 watts and below, but the operation is non-linear and the efficiency is worse if the power is increased above the 5 watt level. So it is not a recommended change except for those special circumstances. If the major use of the K2 is CW only operation at QRP levels on batteries, then it is worthy of consideration. 73, Don W3FPR Alexey Kats wrote: > I have one more question about K2.
