TS-590S low Speech Processor output
I have a TS-590S for 3 months now and absolutely love it.
I have 1 question though.
Do you guys also have relatively low power output in SSB no matter what you do with Processor input (Pro.I), Processor output (Pro.O) and PWR set to maximum?
On TX the 590's power output meter hardly ever shows more than 60-70 Watt out.
On the TS-570 I could read 80-90 Watt out.
Hope to hear from you.
Had the same problem with a '590 purchased a few months ago -- only about 70 watts output.
After tinkering for a few weeks (playing with various radio settings, master reset, different power supplies, comparing output on different power meters, etc) concluded that the rig was defective.
Vendor took it back and shipped me a replacement -- which puts out 90+ watts on all bands.

mines the same..on FM it shows 100+ all bands;but SSB shows around 20w during normal voice ops. even an external PEP meter doesn't go much more than 50-60 ( a whistle gets 100+)
590 is "weaker" than my FT-950 and FT-450 on SSB
If a whistle puts out 100+ watts, then the radio is fine. What do the 950 and 450 put out? How much weaker is the 590s?
I agree if a "whistle" creates 100W indicated output, then the PA is fine, and probably so is everything else.
I'd just watch the "ALC," and see that it's working and indicating as it should.
A 100W PEP rig normally indicates 20-30W on voice peaks on an external wattmeter unless that is a true PEP wattmeter; there aren't many of those on the market, really just a few.
Every SSB rig I own (five of them) that indicate 100W PEP on a true PEP meter indicate about 20-30W on a regular wattmeter.
about the same on FM/CW most bands;105w but about twice as much on SSB (average ) on the same external meter.

I haven't used the 590 for about a month until last night,it's been in the box waiting for Kenwood to come up with a fix for another problem.
I'm about ready to just sell it.
The Yaesu meter is not PEP.
The LP-100 is. But then, so is the Autek WM-1 and the Ameritron meter. I also have a Bird 43P (same as a 43, but with a PEP board installed inside -- that takes batteries to run it), and it's another PEP meter.
But there really aren't many.
I don't know what the issue with your TS-590 is, but normally you'd want to run a rig with its ALC indication as per whatever the manual suggests; "more" often results in overdrive and distortion, and "less" usually results in "undermodulation," i.e., not really achieving the kind of modulation the rig was designed to optimally achieve.
This is why "turning down the mike gain to reduce power" doesn't work.
The Yaesu meter is PEP only in the sense it has an AVG and a PEP position and requires power;but an LP-100 or Autek it's definately not.I've planning on buying either the LP-100 or the Autek for years,but never can talk myself into spending that much for a meter.

The LP-100A is great. Another way to check PEP is with a scope. Send full power carrier to the scope. Remember where the peaks are. Then do SSB and compare the peaks. They should go to the same point
