Jim, again, just as an observation, you place almost total emphasis on
Braille output. I don't know how many of us have Braille printers, but I
suspect many more of us have speech output as opposed to a Braille printer
for outputting the program's information. If you symbolize signal strength
in terms of the number of Braille dots, how do you express signal strength
for screen readers? 

Jim, once again, I highly commend you for your investment of time and
efforts in creating and providing your J J Radio program. It appears to be
an especially major benefit for blind access to the Flex transceiver.

Don, a well thought out set of questions.

You can control the AGC speed and level, the low and high filter bandwidth,
the CW APF, autopeaking filter, the automatic notch filter, the noise
blanker and noise reduction.  You can control the filtering on the other
rigs as well, not just the Flex.

On the Flex, you can also define and adjust their tracking notch filters,
TNFs.  In brief, these are filters that maintain their position, and are
handy for filtering out fixed position birdies and carriers.

See above.

Well, at present, JJRadio doesn't support saving/restoring multiple
configurations, and only supports one profile.  The Flex allows you to, for
example, save multiple configurations in profiles, and then load those
depending on what you want to do.  For example, you might have rag chew
settings that equalize the audio for quality, and then DX settings that
equalize the audio for maximum punch.

One thing I plan to do soon concerns how signal strength is shown in the pan
adapter.  Currently, the strength shown is relative to what's on the air at
the time.  I use the number of dots in a cell to indicate signal strength,
using 1 to 6 dots, 1 for the noise floor, and 6 for the strongest signal on
the band.  So, if you have a quiet band, you'll see perhaps a 6-dot signal
which is really very weak, or even just some relatively quiet noise.  I want
to change this so that more dots represent a truly stronger signal.  I hope
that made sense.

The pan adapter allows you to not only view what's happening on the band
now, but what has happened over a period of time.  I'm not sure how to
represent all that information in a useable form with one line of braille. 
Even using multiple lines, with a one-line display, the information would be
out of date by the time you viewed it.
