Some users reported that nothing was displayed on the graph when using tinySA (basic). The issue was caused by WinSpectrum's default scan setting of 450 points, which the tinySA (basic) does not support (it has a 290-point limit).
Fixed in version 3.0.1.1: WinSpectrum III now detects tinySA (basic) failure when the number of points exceeds 290, adjusts the scan to 290 points, and correctly displays the graph—no user intervention required.

Additionally, this update includes several improvements and fixes:
? Added LNA on/off command.
? Start/Stop Frequencies are now displayed at the bottom of the graph.
? Fixed logfile reading issue.
? Various marker-related fixes and improvements.
? Added Delta calculation for markers.
?
Tested successfully on tinySA (basic) version 1.4-40, tinySA Ultra (non plus) version 1.4-156 and tinySA Ultra+ versions 1.4-196 and 1.4.197.

About the marker's 'Tolerance' field
Some users may wonder why WinSpectrum III includes a Tolerance (%) setting for peak markers when this parameter is not explicitly found in most VNAs, Spectrum Analyzers, or tinySA devices.
This feature is not mandatory and does not modify the raw measurement data. Instead, it is an optional tool that helps locate peaks within a user-defined range rather than just a single frequency point.
For example, if a peak frequency is set to 10 MHz with a 5% tolerance, WinSpectrum will search for the highest peak within the 9.5 MHz to 10.5 MHz range, rather than just at 10 MHz. This can be useful in cases where signals fluctuate slightly due to environmental factors or device tolerances.
The goal of this feature is to make peak identification more flexible and user-friendly, especially when dealing with noisy signals or spectral variations. Of course, if users prefer a fixed peak frequency search, they can simply ignore this setting.
