Hi all! I am sending this message to both groups I belong too since this one 
needs to be documented further, and the word spread.
If you are a sightless user of the TS590S as I am, there is an important 
condition you need to avoid.
When your rig has the driver logo turned on, it only puts out a small amount 
of power, too small to engage the automatic antenna tuner, so your rig will 
not tune and it appears also that you're not getting out at all on a 
particular band. It happened to me! Not an SWR problem which caused my 
antenna tuner or rig not to work, but the drive logo which appears when you 
wish to drive a linear amplifier or transverter with the rig. The button 
which controls this is the one which switches the view for the meter from 
SWR / / power, to ALC.  The second function of that button is to cycle the 
"driver" logo on the display, and to turn on a condition which limits your 
transceiver to a few milliwatts.  If that condition is turned on, and you 
don't realize it, you will not get out on that band, and the condition is 
remembered per band, so if it is on on one band, it can be off on another. 
The remedy is simple, whenst discovered, the way to make sure it is not on, 
is to press and hold the button wiht toggles the display from power / swr / 
alc, and make sure you get the low tone, which turns it off.  There is a 
single same pitched beep for both conditions of the readout which is 
sigtnificant, and I do not yet know if a voice readout can be set up for 
that or not, which may be.  What had happened to me, now, is obvious, I was 
not getting an SWR CW confirmation of high SWR, just the low beep when I 
attempted to tune any antenna for 80 meters.  ND0B, (North Dakota Bill), 
here locally came over, perused the manual, but the solution was not obvious 
to him immediately until he noticed that the bands my rig would attempt to 
tune on any antenna did not have that "drive" logo showing. BINGO, he 
thought, remmedying the problem with the push of a button.
THANK YOU BILL!
As I say, blind users of this radio, ATTEND, and don't hold down that 
display changing button to turn on the "drive" logo for a few milliwatts 
output, unless you intend on driving an amplifier with the rig, and suspect 
that to be the condition if you get a similar condition of not getting out, 
and a low beep when you attempt to use the auto tuner to maximize your 
efficiency on any band and just get a low beep instead.
