I've often wondered why builders/designers of these amps just don't put in 5 or 6 dollars worth of parts and make them cleaner. Focusing the output transistors in throwing out a signal that is on frequency would also mean using all of the transistors ability where it is needed most. Who wants to pay for amping harmonics and IMD anyway? Sure, it might sound louder at the other end (class "c" comes to minde here), but it really squandering the power that is available. Putting the filtering BEFORE the final transistor stage would help insure a cleaner, more accurate and powerful output. Yeah, it would mean changing the board design a bit and cost more for some parts, but the end result would be far better - IMO...

Besides, if they were to make these amps run on track as they should and be a bit more expensive, it would be interesting to see Hams buying/using them. Especially after they have been collectively knocking them for so long. As opposed to those way over priced/underpowered Ham amps which are hyped up. Talk about a racket; just because you can have a license that allows you to use more power and then getting your last dollar for their overpriced gear. What a crock!

Of course, making the radio as clean as possible before it gets to the amp is also a major concern. Putting a scope on the radios output and cleaning up its act BEFORE it gets to the amp is also a critical factor for clean output...

[QUOTE="Robb, post: 142978, member: 8446"] I've often wondered why builders/designers of these amps just don't put in 5 or 6 dollars worth of parts and make them cleaner. Focusing the output transistors in throwing out a signal that is on frequency would also mean using all of the transistors ability where it is needed most.
