Settings for SimpleRadioStandalone with Hornet

If you intent to fly with others in DCS, SRS (Simple Radio Standalone) is a must. So get familiar with it and see download and installation information from:

To make it work best with Hornet, I suggest to use one hat for both radios 1 and 2. I use Thrustmaster Warthog, so I have plenty of buttons/hats to use.

I have selected “Coolie switch” from throttle to be as a radio selector. Hat left click for radio select 1 and hat right click for radio select 2 (radio 1 is left radio on hornet and right is number 2):

To set Radio 1 and 2 select buttons in SRS, go to Controls tab and with set button you can select them:

To make same Radio select buttons work as an radio PTT (Pust To Talk) button, go to Settings tab and set it on:

Now you have a radio selector switches that also work as an PTT switches.
