An eQSL Verified Callsign
KO4RUL Is a FCC Granted Callsign to Wade Lancaster with all privileges.

Our Earth has a diameter of 12,756 Km and is relatively round with bulging at the equator. In modern times humans and machine measure a Geo position to determine the longitude and latitude. From this information it can be determined the exact location someone or something is on earth. For other uses when a geographical location is needed there is the Maidenhead Grid System. In this system, longitude and latitude are divided into 18 bands, creating a world grid of 324 zones called Fields. Each Field is divided into 100 smaller units, called Squares. There are 32,400 grid squares in the world. This website is hosted on a server located in DM43bm All amateur radio station’s location is in a certain GRID SQUARE.

1.25 Meter Band
The FCC has allocated 219-220 MHz to amateur use on a secondary basis. This allocation is only for fixed digital message forwarding systems operated by all licensees except Novices. Amateur operations must not cause interference to, and must accept interference from, primary services in this and adjacent bands. Amateur stations are limited to 50 W PEP output and 100 kHz bandwidth. Automated Maritime Telecommunications Systems (AMTS) stations are the primary occupants in this band. Amateur stations within 398 miles of an AMTS station must notify the station in writing at least 30 days prior to beginning operations. Amateur stations within 50 miles of an AMTS station must get permission in writing from the AMTS station before beginning operations. The FCC requires that amateur operators provide written notification including the station’s geographic location to the ARRL for inclusion in a database at least 30 days before beginning operations. See Section 97.303(e) of the FCC Rules.
