The frequency increment must be positive. If this happens, the execution of the macro is stopped. Several error messages can be displayed in the macro editor in case of a parameter. until 146000 then loops back, waiting five seconds between each transmission. The following macro transmits the same message on the frequencies 144800 MHz, 144900. At each run of the macro, the next frequency is chosen. If the macro is automatically reexecuted using the, the same logic applies. In this case, it allows fldigi to scan all FM frequencies by clicking the macro button. If the last frequency has an increment, it is never taken into account: The last frequency is always an upper limit. In this specific case, it allows to test several Weather Fax broadcast stations, until the operator finds an active one.Ī frequency can come with an increment: This means an implicit range of frequencies from this one to the next frequency. Each time the same (optional) audio frequency will be set to 1900 Hz. It means that the transceiver frequency will be set to 2616.6 kHz, then at next execution to 3853.1 kHz etc. Several distinct separated with a semi-column, in increasing order. The frequency set can be specified in two distinct ways, which can be freely combined together. It can typically be used to iteratively try several frequency for a given test. Each time the macro is executed, the next frequency of the set is selected. The utility of this feature is to allow a scan of a range of frequencies by re-executing the same macro over and over. If the current frequency is greater than any frequency of the set, then the macro choses the smallest, first frequency of this set. When the macro is executed, it choses the first frequency of this set greater than the current one. It is possible to give several frequencies, which specify a frequency set.

The macro tag and its delayed flavour allows the user to set the transceiver frequency to FFF.F (In kHz) and optionaly set the audio frequency to NNNN (In Hz).
