Thinking about my history, I heard this on a low frequency.

"They've got a wall up for anything not on their frequency."

These days, however, I find myself on my father's frequency.

The kid is off on a frequency of his own.

Soon after the war began, he heard a radio message on a frequency used by the Americans.

They can be found on several frequencies including 103.9, 102.7, 95.3 and at least 6 others.

On the first frequency, it can be easily received throughout Europe at night time.

For the first time in months, he felt that they were operating on the same frequency.

The call would continue to repeat until an answer was received on the same frequency.

I stand ready to get a message from you on a fixed frequency.
