Abstract: A system for simultaneously writing current postage rate charts into remote memories associated with a plurality of postage scale or meter microprocessors incorporates carrier wave transmission of encoded rate charts to the microprocessors. A data block, which includes an encoded receiving station address, the encoded postage rate chart, an encoded incremented rate revision designation and encoded error check characters, is transmitted. Each user's scale and/or meter includes a radio receiver, audio to digital conversion circuitry, serial to parallel conversion circuitry, and improper signal rejection circuitry. Optional direct telephone line reception is provided.
