Event-1 Cannon Won't fire

[i_am_lugnuts]

I bought this campaign quite a while ago and am just getting around to flying it now.  Imagine my disappointment when I got the F-5 in my sights in mission 1 and squeezed the trigger and.... nothing.  I checked my bindings and tried to shoot with the space bar.  Still no luck.  I backed out and loaded one of my own F-14A missions and it worked just fine.  I went back to the campaign and reloaded the ammo before start up in the event that maybe it didn't load correctly.  Didn't work. I loaded a Pair of AIM-9s and they did fire correctly.  I also noticed some strange responses from Jester during startup.  He acknowledged me in the affirmative after I put the right throttle into idle and again when when I turned on my HUD.  Something seems askew. Any thoughts?

No mods are installed and a campaign reinstall was done as well as a DCS repair.

I bet it’s because you have the gun trigger assigned to the spacebar. Assign it to smth else. Dcs thing. As for the affirmative, that’s the automated RIO at work right there.

Do you have the airsources turned to both....no air, no guns.

Sidewinder firing point me in that direction. Another plane in airstart (canned missions) has the air source usually to both

Thanks guys. Lt Jaeger, I think you nailed it.  I have a bad habit of leaving the air off.  The noise annoys me...lol  That's probably what happened.  Reflected, I took your suggestion too.  There's no need for to me to have the spacebar bound in a mission that requires frequent spacebar use.  I never use it anyway.

So, it works now.  I had a ball in mission 1 and landed with 800lbs of fuel
