+# Current work list (for Version 0.29)
+  1 Testing CAT Control with Software using hamlib on Linux
+  2 BFO setting based on current value - complete
+  3 Select Tune Step - Testing
+  4 Change Tune control type, Do not keep the original source - Complete
+    - Coded differently after clearing the original source
+    - Prevent malfunction by applying threshold
+  5 stabilize and remove many warning messages - by Pullrequest and merge
+  6 Study on improvement method for cw keying - need idea
+    - set ADC Range value
