Tac/Com Control Head Manual | SM06 Rev. 4.10 |
For each channel stored in the control head, there are three possible data entries; identification label (ID), receive frequency (RX) and transmit frequency (TX). If equipped, the radio may also have tone and scan information associated with these entries. Note that
The ID label or channel name has no effect on radio operation, and is provided for operator/pilot convenience in identifying the selected channel. Any alphabetical character, the numbers
Help can be used at any time when editing, to give instruction for the operation being performed. The exact data that pressing HELP provides depends on the current activity, as it is
It is important to remember that while frequency data may be edited, the radio itself must be an agile radio, with the AGILE MODE ENABLED on the interface card for any change to actually take place. Crystal controlled radios, or PROM coded radios which allow editing of this data in the master edit mode (for reference only), will not change frequency after editing. Receive frequency editing is also allowed for guard channels (also crystal controlled) used in some radios, but again, this is for reference only, and no change will take place in the operation of the radio.
When editing RX or TX frequency data, only those frequencies the control head recognizes as valid can be entered, and only in the fractional multiples allowed. If mismatched multiples occur when editing, a warning message, FREQ ERROR will appear, because the RX and TX frequencies must both be divisible by the same synthesizer interval.
The last positions (far right hand) on the RX and TX lines are for tone data (these locations have scan flags on the ID line). Depending on the type of radio installed, differing codes are possible here to represent the CTCSS (or
