Narrative:

The controller cleared me to go direct to djb. Approximately 100 mi east of djb I tuned in 113.4 (dxo) rather than 113.6 (djb) and proceeded direct to detroit. After about 50 mi the controller asked if we were on an assigned heading and then I noticed my mistake and corrected my heading towards dryer.
