Channel width in favorites get doubled when tuning onto frequency

[bierviltje]

The channel width set in favorites get doubled after it tuned onto the frequency when clicking on the favorite. For example: 8 kHz becomes 16 kHz.

Another small issue in favorites: it doesn't tune exactly on the stored frequency. Sometimes there a mismatch of a couple of Hz. For example: 157100000 becomes 157100006 after it tunes onto the frequency when clicking on the favorite.
