Temporary radio test command generator

Use this page to join the shared temporary radio test without overwriting the node's saved primary radio settings. The default window is Monday, September 21, 2026 at 5:00 PM through Wednesday, September 23 at 5:00 PM Pacific time (48 hours), using 910.1 MHz, 500 kHz, SF8, CR7.

The page reads the complete test definition from its URL. Change the query parameters to reuse it for a different window, display time zone, or radio tuple; no source edit is required.

    The test will include bridges. If the Puget Sound area experiences a
    widespread power outage or loss of cellular service, we will end the
    test early and revert to the normal 910.525 MHz channel.

    Run <code>get radio</code> and record the saved primary tuple. Both
    primary TempRadio methods return to that saved tuple; they do not store
    a return tuple inside the temporary command. On a Companion, also run
    <code>get radio2</code> and <code>get radio2.cross</code> so you can restore
    any non-default secondary-profile setup.

The scheduled commands require current full-parser firmware. Companion tempradio2 and tempradioat2 require a build with dual-radio-profile support. If a node reports an unknown command, update it or use only a method that its installed firmware documents.
