When creating a new memory channel, the default frequency is not always valid. The default frequency is always 146.01 MHz, which is only valid on radios that support 2M. On radios that don't support 2M, this bug makes it so that the only field that can be used to create new channels is the frequency field.

Steps to reproduce:

Open a .img for a UHF-only radio¶

Click on the Name field of an empty memory channel¶

Type your desired channel label¶

Hit enter.¶

Now, Chirp attempts to set Memory.freq to 146010000 and encounters an out-of-range error.

Desired behavior would be for Chirp to pick a default that is within the valid frequency range for the radio.
