place of the pot presently in a circuit with this method of squelching. Also good in voltage divider networks, and current controls. Notice other versions of these
The other method of squelch control uses the quieting phenomena during reception of a signal to open the squelch. When there is not a signal there is plenty of random noise received, especially high frequency noise. This high frequency noise is used to close the squelch when the quieting effect is not present. With this method all that is needed is the three pot connections on the URC1 in place of the pot that previously controlled the squelch. These variable pots can also replace the level detection method by tying the wiper output to the high output.
To use the variable pots:
This is the simplest way of controlling signal levels such as volumes, voltages, powers, etc. Always tie the common ground of the URC1 to the common on the unit you are trying to control. If you are worried about the common on the unit to be controlled not being isolated, run the URC1 off of an isolated power supply. Using this method should protect the URC1 from damage from grounding errors. L0 does not have to be tied to common, but must not go lower in voltage than the common of your URC1.
To use a Level Output as a Variable Power Supply or Voltage Source:
This configuration allows a user to adjust a
