23cm Band Plan

Receiving JT4 from Beacons

If you are using transverters, set appropriate frequency offsets on the Settings | Frequencies tab. Offset is defined as (transceiver dial reading) minus (on-the-air frequency). For example, when using a 144 MHz radio at 10368 MHz, Offset (MHz) = (144 - 10368) = -10224.000. If the band is already in the table, you can edit the offset by double clicking on the offset field itself. Otherwise a new band can be added by right clicking in the table and selecting Insert.
