The colour of the red in the scale being darker the lower the reading does not help and neither does BRIGHT white test overlying the scale numerals. Personally, I would like to be able to see the bar better in the lower regions of the scales.
I would apply these comments to all similarly coloured scales too. Could these not be user configurable?
Sorry for the rant

I agree the low contrast indicators are hard to interpret quickly. When I get an antenna very close to "in tune", the SWR almost disappears. It doesn't completely disappear, but the contrast is so low that I have to slow down my tuning changes quite a bit to see where the null is. This means I'm transmitting tuning carrier longer than I otherwise would need to.
My conventional crossed pointer forward and reflected power meters are much easier to work with. They have sharp black needles against an illuminated face. I realize that implementing a crossed needle type of display in SSDR isn't likely to happen because such a display would consume too much screen real estate, but if we can't have such a display then let's at least have one with good contrast.
This is a big bang for a small buck issue. Changing this display is not a significant software effort (I was a SE in my previous life) but it would make a big difference to the "irritation factor" associated with the SSDR interface.
Of course, they have been designing Digital Spedometers for a while..so they obviously figured out what works
BTW... my car has a heads up display for the speedometer on the windshield.
Sorry for the Fuzzy Picture as it was taken as the reflection off the windshield
.. it displays the speed in large Bright Yellow easy to read Digital Numbers.. no analog.. I no longer ever look at the Analog display as that takes too long to interpret and is never that exact... plus I have the advantage of never having to take my eyes off the road..
I really wish my Flex had digital displays for Power, SWR and S Meter (dBm) all in one place with user selectable color schemes...
I like qrp work and I would like to see the ability for expanded scaling on the rf power meter wrt power out and appropriate selectable power out. For example three options each reflecting full scale deflection:
1. 0 - 1.2w
2. 0 - 12.0w
3. 0 - 120.0w
Overall, the current meters are nice but it would be neat to have the ability to select higher precision or an expanded view.
But as a web developer for modern devices I do know the blue / red / black can cause issues for some people. This was and still is a godsend http://www.uxmatters.com/mt/archives/2007/01/applying-color-theory-to-digital-displays.php I find figure 6 probably the best on my eyes for something that needs to stand out. As this is all WPF maybe the colour wheel can come into play :-)
