Yes it is normal.
But you do not need measure the frequency all the time.
What I do is (my oscilaltor is a tube one) - I let it warm up for 5-7 minutes, and then I set up a frequency on a stable signal and then I simply switch the signal to radio and no longer measure the frequency, until I need to change it, at which point I repeat the process.
If your generator is stable there is no need to constantly monitor the frequency.
