Not sure if it's ch25 you are referring to in your reply nick regarding just how bad these amps are as yes he does sayBlack Spirit wrote: ↑01 Jan 2018, 16:33Finally, Someone who agrees with me that the KL203 [MOSFET] is an awful amp, Just by seeing the SWR jump when powered on indicates the amount of rubbish being spewed out of them, I dont have the pleasure of owning a spectrum analyser but i would love to see the results of a KL203 with 5-15w input.
You just have no idea of amonut of garbage going out when you overdrive that box. Lucky, I do not have you in the neighbourhood.
But also earlier says "
kl203 works acceptable as long as you do not exceed 2W AM/FM and 10-12 SSB on input. Looks not that bad on the scope and spectrum analyser.
More drive, more distortion. Tested by myself.
Appreciate they are cheap and cheerful and not for everyone!!!
