Paul Prestia, KA3OPZ informed the FWRC websmaster that he has configured a continuous tone-coded squelch system (CTCSS) tone of 141.3 Hz on the output of the FWRC repeater on 146.91 MHz, located on the campus of IPFW.
The repeater’s input continues to operate on carrier squelch, which means CTCSS is not required to use the repeater. The tone on the output, however, will allow users to optionally configure their radios to remain silent except when the repeater is transmitting, thus preventing the reception of intermodulation interference, distant repeaters on the same frequency, etc.
The table below reflects the current CTCSS status of all FWRC repeaters as of today:
Repeater (MHz) | Repeater input CTCSS (Hz) & status | Repeater output CTCSS (Hz) & status |
444.875 | 141.3, required | 141.3, present |
146.76 | 141.3, optional | 141.3, present |
146.94 | None | 141.3, present |
146.91 | None | 141.3, present |
