Go to file / preferences / bands/ (click) frequencies and edit the upper/lower limit. Found this fix in another post.
Strange behavior after update. Since updating from 2.4 (something) CQRLOG wont accept 146.520 as a freq. When trying to save a FM simplex contact. I get a popup box that states "You must enter correct frequency (in MHz)" and wont accept anything above 146.001. It will accept 146.000 and below. Anyone have an idea why. I perused the config files looking for a freq. limit for each band but was unsuccessful in finding anything that looked appropriate.
Not a deal breaker but I know the software didn't use to have this issue.

Go into Preferences-->Bands-->Frequencies, look 2m, there you can
find highest value is 146,000. You can modify all these by your self,
suitable for you.
