Further to this end, my experience and practice tells me that an analog
meter under normal speech will show a power level of some 6 dB less than the
true peak level. Some from Europe may argue that this could be as high as
10 dB if one uses the DIN scale. OK, so be it. This goes back to the
discussion of VU meters vs. true peak levels on program circuits. With this
thought in mind then if the analog meter {yes I understand meter dampening
and etc} shows 25 watts and one believes that there's a 6 dB difference
between average and peak levels then the peak output will be about 100
watts.
Using the same rational of 6 dB and seeing 75 watts on the same analog meter
would then tell me that the peak level is some 298 watts. I don't think so
unless there is a significant amount of processing or compression taking
place in the TS-50.
This goes along with many stations where I hear the operator state that the
meter is showing 100 watts out on the power meter and they are running one
of the modern day 100 watt radios. {You name the brand.} And they wonder
why folks complain about their wide signal that lacks significant dynamic
range or better yet the background noise is only 2 S units below their peak
signal or one can hear their adenoids rattle when they inhale. That's
clearly quantity over quality.
I'd say that without excessive processing that 25 to 35 watts is about
correct for a 100 watt radio.
