I have a QRPLabs 50W amp kit in the process of construction. I would like to use it with my QMX+ but would like to be able to switch bands on it. I was thinking of just bypassing the LPF in the amp and feeding it into an external LPF that can be switched to different bands either manually or via a signal from the QMX+. Looking at the schematic, I would jump from the C8/transformer junction to C15, omitting the LPF components. I would mostly use 40M to 17M. probably never higher than 17M. I realize it's class C so only for CW.
?
Would this work or is it a Bad Idea?
