Was told they are a lot better than the bv150s that i use. Had one of red ones before lasted 4 days till it popped. Hence why i now have bv150 splatterbox.

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.

For longer talking I suggest to put 12cm fan on top of it.

I normally put around 7 watts AM/FM and 18Watts SSB into mine and have had no issues.
Just be careful using it with a radio such as a PC-999 Grant, as they might give 8 watts on deadkey but with modulation power will rise high enough to hill the amp.

You just have no idea of amout of garbage going out when you overdrive that box. Lucky, I do not have you in the neighbourhood.

Well according to the specs I am not overdriving it.
No complaints yet, exept on one occasion a radio I was using had a fault.
I do use a reasonably good low pass filter.

Finally, 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.

I bought one new and had SWR Problems, Even with an inline filter, Personally i'd avoid them at all cost, They spew out more crap than spamdemon

Specs given by rmitaly are pure b$. Similar to zetagi etc.

I sold my analyser over year ago since I do not play with those toys anymore, but I still have a scope and when I get one of those boxes I will make some screenshots.
