10 * log (1500/100) = 11.76 dB
It is generally a good practice to ensure that a linear amplifier stays linear. The fastest way to make an amplifier go nonlinear is to overdrive it. The key is to take power output up to the limit but not over it.
I'll let you in on another secret. You get far more bang for the buck out of your antenna than out of your amplifier. Compare a 100 W transmitter to a 1500 Watt Transmitter/Amplifier combo
A good yagi-uda or log periodic antenna might give you 24 dBi of gain for a fraction of the cost of an amplifier. The difference in dB might not seem like a lot but in performance it is substantial. I know lotsa guys who swear by QRP on top of Pikes Peak.Code:10 * log (1500/100) = 11.76 dB
Your correct that antenna gain is the best way to increase effective radiated power and has the added bonus that it also increases your receiver's S/N ratio as the antenna gain is fully reciprocal for both sending and receiving.
However 24dbi gain is really not achievable in any practical manner in the HF ham bands where long distant SSB contacts take place. Heck, 10db gain is going to cost some bucks especially in the lower frequency HF bands.
To the OP about quality of SSB generation. Good carrier suppression is but just one requirement for a good sounding signal. Audio processing, bandpass filtering method and bandwidth is also equally important. Most hams these days use quite a bit of audio compression to keep the average RF power output higher while sacrificing a little audio quality for that extra punch.
Make no mistake, SSB is not a hi-fi quality sounding modulation method, it's designed to generate the best S/N ratio signal for a given amount of power consumed. No power is wasted transmitting a carrier or the opposite sideband. It's power efficiency is it's best attribute, only CW (more code), received with a narrow bandwidth receiver has a higher power efficiency value.
I know. It is awesome aint it? I think it's sounds better than regular AM.
I did not quite follow you. What is the reason for the VOX? A SSB xmitter with a well balanced modulator will not output any carrier until it is modulated with voice. That is the whole selling point of SSB.
The key here is well balanced modulator. See some of your previous post.
Well I think it sounds like Sh*t compared to good FM stereo modulation, but like in wine tasting, it's a very subjective thing I guess.
Well, if your talking about music, yeah, no doubt. I should have stated A3 modulation. So I'm talking voice communication. I think SSB far exceeds all other types of modulation in quality of signal alone, not to mention the efficiency factor.
You're not making yourself very clear?, SSB is probably the poorest 'quality' you can use - BUT - it's one of the most efficient, and perfectly satisfactory for voice communications over long distances. Wideband FM isn't an optionand even narrowband FM (with excellent voice quality) takes far too much bandwidth, and doesn't travel anywhere near as far.
If you want to better SSB, then move to CW - goes considerably further than SSB, but it's also a lot slower and less convenient.
Of course they have the same meaning. The SSB postings sounded horrible like ducks quacking with zero intelligibility.Voice sound quality and voice intelligibility do not have the same meaning.

Modern telephones sound adequate with voices because their transducers have a wide bandwidth and low distortion. Old telephones with their carbon mic and tin-can earphone had poor sound quality and poor intelligibility.
Some cell phones sound horrible. My daughter's new cell phone transmits no high audio frequencies. My son's new cell phone transmits extreme distortion. When used handsfree, both cell phones chop the voices.
I am watching live TV. When the people speak directly into a microphone the sound of their voice is crisp and clear. TV has a flat audio frequency response up to 15kHz and low distortion like wideband FM radio which produces excellent sound quality and intelligibility.
