This discussion makes me appreciate my JJRadio program which I've written,
and works well with my TS590. When the program comes up, you immediately
see the important stuff such as your Vox setting, current VFO, whether your
in split mode, the frequency, and the RIT and XIT offsets if any. It also
shows the continuously updated s-meter reading. There are other screen
fields that allow you to see and set the radio's parameters. It's kind of
like an accessible Ham Radio Delux for the 590. It even allows you to look
through the menus, telling you what each item is, not just the menu number.
You can then change the item, and you are shown the meaning of each setting.
I'll be happy to send anyone the documentation file for it, in HtML format,
if you'd like to see what it's all about. If you want to try it, I'll send
you the program. I would ask that you provide me feedback on how it works,
especially if you have problems. I'd like to get it in the hands of some
other operators, to see if you like it as well as I do.
It's a work in progress, and I'm adding to it as I speak. It's my home brew
project, and I'm having a good time with it if nothing else.

Howard:
It's hard to know what the problem is and how to fix it without seeing it
first-hand, but my immediate hunch is that you maybe are in split frequency
operation. To check this, press the second button in the first column of
buttons immediately to the right of the main tuning knob. If, for example,
you are in V F O A and not in split operation, it will just say A. If, on
the other hand, you are in split operation, it will say the letter S
followed by A, indicating split.
Hopefully, others will have additional thoughts.
And above all else, don't worry, we've all been in similar frustrating
situations.

Hi Tom, If I'm right, you have one of these 590s? Can you, or maybe =
anyone here, make a suggestion? I don't understand plenty of the =
functions on there and right now, I can't make it transmit on 75 meters. =
I don't know what I did nor how to undo it. I push buttons for hours = and
it just doesn't work.
Thanks and 73.
