3.4.1Radio Specific Controls

Radio-specific

Controls

Radio specific controls allow the general operation and function of each radio to be modified independently. The radios are identified as 'RT1, RT2', etc. to the left of the display, and the line of text continues through the display to connect to the specific controls for that radio on the right hand side of the control head. The exact functions that are provided on the front panel via the radio function switch will vary with each radio type. Some radios support very few features, while others require both the front panel switch, and a number of status line functions to set all of the radio functions. Guard controls are not available on all units.

In general, the GUARD volume control permits a zero volume level without turning the radio off, but in some instances, such as USFS GUARD RX controls, this will not be true. OAS government contracts require that this level not go to zero regardless of pot setting, with a minimum fixed output at all times.

A second set of controls is provided for guard operation only when 'H', 'U' or 'V' interface cards are installed. Note that the GUARD volume control has no OFF detent position. Forcing the control fully counter-clockwise may cause switch damage. The internal minimum guard volume adjustment is accessible through the right side of the control head. The additional guard controls provide selection of the guard 1 and guard 2 channels, plus a separate RX status indicator.
