I believe that the K3 and K2 are unique in that they switch the PA out of circuit when low power (below 12W in the case of the K3) is used. Why do they do this? Would it not generate a more linear signal and result in less stress on the low power PA components if the high power PA was used, where fitted, even for power levels of 10W or less?
I have recently become interested in the WSPR beacon mode (http://physics.princeton.edu/pulsar/K1JT), which involves transmitting a continuous signal for periods of 2 minutes. At a level of 5W the underside of the K3 gets uncomfortably hot. Since this is the sort of thing you want to leave running all day, I'd prefer the 100W PA with its big heatsink and pair of fans to take most of the strain. Is this possible? ----- Julian, G4ILO.
