OPERATING THROUGH REPEATERS
Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. Generally they operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over much greater distances than communications without using repeaters.
Most repeaters use a receive and transmit frequency pair with a standard or
PROGRAMMING OFFSET

If the offset transmit frequency falls outside the allowable range, transmitting is inhibited. In this case, adjust the receive frequency so that the transmit frequency is within the band limits.
