Matt,
Well there is some good news. I guess there is a setting messed up in
MMTTY. You can revisit that some other time.
If your interface is keying the radio and generating the psk tones, that
is a step in the right direction.
A lot of these programs have junk that flashes on the screen and gets
grabbed by the screen reader. You might want to look under the "view"
menu. You will probably see a number of things checked, like status
bar, clock, and maybe some other junk. Try unchecking some of this
stuff and see if the extra speech goes away.
I don't remember what the high and low cut frequencies of the 480's dsp
are. You should probably open them up a bit. If you plan on using
the data mode filtering, you need to read up on that in the 480 manual.
I forget which menu in Digipan, but arrow down and you will see one
that says "use arrows for seek" or something like that. Check that,
and you will use your pc's keyboard left and right arrow keys to jump
to the next signal.
You don't tune in the signals with the vfo knob. Get on 14.070 USB
for example and use the arrow key (in this case right arrow, if I
remember right) and the software will jump to the next signal it sees
and decode it.
There is an area of the screen called "the waterfall display". That
really can't be accessed with a screen reader. Each signal is
represented by a double line like a railroad track. A sighted ham would
use his mouse to choose which signal he wants to decode and click
with the mouse. Then the text from that signal starts displaying in
the RX window.
Setting the menu mentioned above to use the arrow keys will let you
jump to the next signal without a mouse.
I'm glad the TX side works for you. Now you really need to bone up on
psk. Read the docs for the software and maybe some tutorials online.
you will have the same issues getting the screen reader to do what you
want as you did in the other program.
There are a boatload of psk programs out there. You aren't married to
this one.
Hey, it's a hobby. Nobody said it was going to be fun.
