The column started as a monthly in October of 1996. It switched to a bi-monthly format in February, 1998. The final column ran in December of 1999.

After the completion of the column's run I continued to write for Monitoring Times on other subjects, dealing primarily with trunked radio systems and scanners. You can read more about that at www.signalharbor.com.
