An example here would be a low and peak temporary hold display. Normal would be green, max would be red and blue min signal colors. The red and blue would last a second or two so the green level indication could respond quickly to enhance the display. I like the SDR-1000's digital meter (in dBm), as the averaging function (rate) can be adjusted to the user's liking, or turned off. The peak hold and normal display colors (in gradient color hues) can be changed, too, for best visibility. There is also a really cool "analog" representation of an s-meter as an option, that displays in true s-units and incorporates the peak hold feature. The "needle" changes color briefly at the peak reading. It's a high-resolution and realistic representation of an S-meter, and floats in a separate window so you can place it on the Windows desktop wherever you like. Finally, because the SDR-1000 is user-calibrated with a Elecraft XG-1 or other signal meter, the digital meter and the "analog" s-meter are highly accurate across their range. My SDR-1000 blog entry from April 13th shows this S-meter in its prior form, before it was changed to a "floating" window. Analog or digital dBm is certainly more useful that s units. You can program any kind of display you like on the computer supported radios. I would not want the averaging on at all preferring that the display update as fast as possible so that the rate of signal fluctuation can be seen in real time. The drawback is that with rapidly changing signal you would have a tough time seeing the min and max and that is where the min and max hold for a second or two with the different colors would display. I've seen this type of display on audio VU metering and I think it would be good for signal strength indicator. -- Telamon Ventura, California |
