1) select the number of 100 Hz channels you want visible 2) select the start frequency for the browser (your transceiver may not rx signals below this value) 3) select the inactivity timeout for the browser.

This text can be a simple text snippit such as "CQ" or any regular expression. With a regex you can specify a more generic pattern, which means that you can match more things and your search is somewhat noise tolerant. Here is an example for a CQ from a US station (should match most callsigns): cq.+[aknw][a-z]?[0-9][a-pr-z][a-z]{1,2} This says "cq followed by at least one character, followed by one A, K, N, or W, followed by an optional letter, followed by a digit, followed by a letter that is not q, followed by one or two letters". The search is case-insensitive. All plain text is a valid regular expression, unless you really had been looking for these metacharacters: .[{()\*+?|^$ These will have to be escaped with a backslash. |
