BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Beacon Call
A Beacon Call checks for the best channel to use between two stations. It
allows the Operator to determine the signal quality between their station and
the station they want to call on a particular channel, but without actually alert-
ing the station they are doing so.
When a Beacon Call is sent to another station, and if the channel being used is
open, the remote station sends back a distinctive four-tone revertive signal. The
Operator can judge the quality of the channel for communications purposes by
the strength and clarity of this distinctive tone. Using Beacon Calls on several
available channels will determine which channel is best to use either subse-
quent Selcalls or Telcalls.
Note: both stations must be programmed for Selcall or Telcall operation.
