Opinions/Radio for a DX1600X

A liner Class C amp is an oxymoron.

Class C amps are non-liner by definition. They work well for CW and FM and are more efficient than a class A or A/B amp but should not be used for AM/SSB.

For AM/SSB a class A or A/B should be used to prevent spattering.

From looking at the wattage input specs it looks like it requires around 20 to 30 watts carrier and 100 watts peak drive to reach full power output. I guess a radio that would be close to those numbers would be a Galaxy 47 or run a basic radio into a TS Mod V driver, like I said earlier I have never run that much power but I have always liked Galaxy radios so I would try the 47, just my 2 cents.

 

General HP 40 has a carrier of 30 watts and pep of 120 watts, it may match up good.

 

It’s not what you or CW Spook had said. You had said……..

while CW Spook said the opposite Neither is correct as AM and SSB have the same requirements to be amplified without distortion.


The same class of amplifier works for ether AM or SSB (USB/LSB) as the sideband modes are just a hybrid of an AM signal (remove the carrier and one of the 2 sidebands of an AM signal). Enter a Class A or a Class AB amp will work fine for ether AM or SSB modes.

Because a Class C amp is non-linier it will cause distortion on any mode that modulates the amplitude of the carrier. CW has no modulation and FM modulates the frequency not the amplitude of the carrier so a Class C amp works fine for them but not for AM or SSB.

 

Ubu is correct, and I misspoke. Class C is for CW and FM. Actually, there is a way to make Class C work for an amplitude modulated signal, but I don't believe it's ever been implemented commercially. That said, traditionally, the way to get a high power AM signal was to modulate the base signal with a high power audio signal, e.g., a pair of 811's in the final for 500 watts, modulated by a pair of 807s with about 100 watts of audio.
