you wont have every asshole with a smartphone seeing and trying to mess with your net.

what frequency do you believe this transmitter uses and why do you believe smartphones in the US can mess with it?

is there some reason you believe 446mhz is an unlicensed band in the US?

stj:
you said "wireless" so i took that to mean wifi modules.

search LPR yourself, it's used for stuff like car fobs.

i'm using encrypted spread spectrum 915mhz, which is a much better solution.

315mhz/433mhz car fob frequencies are not available for use in the US for general purpose unlicensed communication. the band use is quite restricted.

446mhz which you mentioned earlier is used in Europe for PMR unlicensed. in the US, that is right in the middle of the licensed 70cm band.

Based on your recent post, I think you are what you have said.
You are paranoid and egoistic.
If all you care is NASA or MIL-STD quality, then don't spam on a forum with most users making consumer/industrial stuff for a living.

have you ever seen a large gasoline fire ball go off? Or a 15 inch shell explode? Or maybe some high explosives someone had laying around to add some ground boom to a show?

   Yes, yes (and bigger) and no, not a fireworks show, otherwise yes up to 500lbs .MIL.

You can connect this thing to a fused blasting cap if you want.

   Blasting caps aren't used in commercial fireworks. EVER.

What do you think I am complaining about a fucking alarm clock? It's a detonator circuit.

  Wrong again, motor-mouth.

Do you think someone is gonna give a shit about class D restrictions at a private party or something?  :palm: :palm: :palm:

   Are you accusing the OP of ignoring the restrictions at a private party?  Would you care to provide some proof of that accusation?

I think its just people that never experienced a close up explosion or real heat in their life talking a buncha idiotic shit in this thread.

    I think the only person in this thread that that applies to is yourself.

    FPAG member and I've been been making safe fireworks for over 50 years.  You OTOH don't know WFT you're talking about.

   I usually ignore threads like this that display obvious signs of major stupidity but I got tired of you ragging on about things that you clearly don't have any knowledge of.  In at least half the cases you don't even know the proper names of the items that you're carrying on about. 

   OP, nice work, carry on.

You clearly wrote that you don't give a shit based on your handling of pyrophoric, toxic and carcinogenic chemicals and synthesis of high explosives without safety precautions in your boxers. TNT, RDX, HMX, nitrated plastic / plasticizer fumes.. all that stuff is not great for you buddy. Do you even know the properties of nitric acid oxidized encapsulant fumes? Maybe read about effects of substances like TNT on a human.

Maybe you should not be doing safety analysis ? I would not want to get TNT containing solution spilled on me. Perhaps invest in a lab coat, fume hood, goggles and a mask?

  Blah, Blah, Blah.  The OP talks about a firing box and YOU start carrying on about inadequate wiring and ignitors and now you throw in Nitric Acid, RDX, TNT, HMX and other things that are not and have NEVER been used in fireworks.  I'll say again that you have no idea what you're talking about and are just making s**t up!  You need to stop before you prove yourself any stupider than you already have!

   Interestingly there is one high explosive that at one timewas widely used in fireworks.  It's one of the few names that you haven't thrown into your arguments so obviously you don't know what it is.
