+Quisk Version 4.2.37  August 2024
+=================================
+Quisk now has a new option "Fixed tune offset" on the Config/radio/Options screen. This is meant for
+Softrock radios that need a constant audio frequency to simplify amplitude and phase corrections.
+The value zero means no change to Quisk tuning. Otherwise enter the fixed frequency offset from center.
+If you are using the obsolete "mouse_tune_method = 1" please delete it and use this new feature.
+If you use softrock_tune_vfo.py as your hardware file, you should replace it with softrock/hardware_usb.py.
+
+Quisk now works on Python 3.12. And I fixed a bug in the small screen graph width.

 A high quality sound card is advisable. The analog mixer is not perfect, and it will be necessary to adjust the I and Q
 signals to equal amplitude and 90 degrees phase difference. Use the Config/Config screen buttons to
 bring up an adjustment screen. Adjustments must be made for each band, and separately for transmit and receive.
-The adjustment depends on both the VFO frequency and the tuning offset from the VFO. See my paper 
+The adjustment depends on both the VFO frequency and the tuning offset from the VFO.
+Quisk has an option to fix the tuning offset to a constant and to tune with the hardware.
+The tuning offset then has a constant correction and it is only necessary to correct for the VFO,
+a much less sensitive correction.

 A good strategy is to pick a VFO near the band center, and record corrections at an Rx frequency of -15000, -1000, 1000 and 15000 Hertz.
 If the corrections are sensitive to VFO, record the corrections for these same Rx frequencies at VFOs equal to

 To create a Receive correction point for a given VFO and frequency, attach a signal generator to the SoftRock through an attenuator,
 and look at the image on the graph screen. If the signal is 3500 Hertz above the VFO, the image is 3500 Hertz below it.
