Narrative:
No backup frequency for 1 week. In the past we've only had 1 backup but with ground control frequency OTS for which the backup is now in use for we have absolutely no backup frequency. In the first place the tower should have more than 1 backup. Callback conversation with reporter revealed the following: reporter stated the ground control frequency was blocked by a stuck microphone from a ground vehicle for a week. A vacant frequency was used for ground control. Reporter feels each position of operation should have another frequency available in case the primary frequency is blocked or OTS.
