We've added a few improvements to SpurFinder Version 3.1g. Some of the improvements are:

• In the demo version, the LO can now be adjusted to 16.0 +/-0.25, which will allow the user to see some of the input and output frequency tracking features
• The "Sliding Input Frequencies, Fixed Output Frequencies" and "Fixed Input Frequencies, Sliding Output Frequencies" controls now work for both up and down conversions, high and low side LO's (all combinations)
• The filename for the current spur scenario is displayed on the front panel for better documentation of results
• This is a free upgrade to users of Version 3.0 and above
