Response Inhibit

As of R2.7.0, it is possible to prevent a radio from responding to any command from a rogue (unknown/unauthorised) radio. Examples of these commands include Radio Check and Remote Monitor.

This feature is different from Transmit Inhibit in that, with Response Inhibit, the user is still able to PTT and transmit.

With Transmit Inhibit, all transmissions from the radio are turned off - including PTT presses.

This is a CfS feature and requires the purchase of a licence in addition to the firmware upgrade.


  1. Thanks Wayne for your reply on OTAP & remote monitoring, I thought it's best I follow up here to keep your website on topic!

    Is Response Inhibit a per radio licence? What exactly is or isn't blocked when activated, or is it customisable? I understand their PTT will still work, but will it stop all ARS messages, or can some devices be set up as 'trusted devices" (eg Trbonet)?

    Thanks again,

    1. Yes, the licence is done per radio.
      With this enabled, all transmissions, except that which is achieved by pressing the PTT, are disabled - that includes ARS etc.
      Bluetooth and WiFi are not affected.
