My microwave practice is pretty rusty..

For one thing though, the 'horn' - inlet behind plastic at top, side - is intended to feed into a 'tuned cavity': yer box! Mismatch there is (back to Helmholtz). ie you might transfer negligible power unless you do a proper match. Recall that, one of the interlock features (should \ufffdswitches Both fail) - IS this low but not negligible spraying out into the room.. Experimental suggestion: Forget just.. removin doors and of course buggerin their interlocks {no bugger jokes - I had to explain a sign to a nun from England! once, askin me about a sign on a Big red flashin lite in the control room, When this light flashes - a control circuit has been buggered Heh. Wanna know the definition of tact ?} Anyway, I'd guess - assumin old ones are so cheap ya don't have to actually Use it again: remove the Klystron assy with its vestigial 'matching horn' and maybe just pattern your add-on to that: to a similar "expansion rate" of the 4 sides. Maybe some links somewhere can give a better clue; 2.4 GHz is pretty low \ufffdwave freq. anyway, so your precision won't need to be of the sort of ~S-band and Real microwave physics. A valuable piece of data would be: some way to guess the permeability (?) of Your particular Soil / er mound VS that of air - and see a EE book re loading the horn appropriately. Sorry it ain't a no-brainer - though it might be to someone working daily in RF stuff. I'd definitely invest in an el cheapo leakage meter. A thermometer can measure the achieved efficiency "into the mound". Turn off [First!] take rectal temp - the mound that is - switch on. Tinfoil might even be a good way to invent your own er tuned cavity between. You got it right when the ants start streamin out. Planned for that? They are hardy little beggars - even Inside an oven.

And in terms of species, H. Sap. might be older than a particular type of fire ant, insects being fast plastic evolvers. But ants in general have been around a lot longer than primates.

I mercilessly off only.. the occasional Smart-ass one who makes it into the kitchen, since I know they follow odor trails of any One such who returns with a Soups On! message. Generally house remains ant-free, and I don't much mind the little beggars sharin the local trash til - a bunch of them go for a long vacation when I xfer the bag to the wheelie thingie for pickup. Beside the point re fire-type I guess. Back-hoe - one scoop to faraway vacant (?) lot? fAntasizin again..

They swarm quickly and leave postules when they bite and can kill a small child if enough bites comb ined with antihistemic reaction. Just shudder at what laying all the poisons will do. Never met a nursery owner down here who doesnt have 0ne or several cancers at the age of 50. I be in the trpics so the bugs reign. My idea of a cone emitting microwaves or other type of wave (sonic radar radio etc ) that will have a minimal environmental impact somewhat safe to use is what I am after. thanx, bill can I have my ones and zeros back?

At humongous levels @ ~54 Hz IIRC - shakes guts to bits, 4x Hz - anal sphincter gives up yada Your guess, the resonant freq. of fire-ant abdomens - surely up there; maybe KHz. Sustained 100 W audio with heavy (lead sheet?) sound absorber over back (facing the world) - might be as effective as \ufffdwaves. Voice coil may need cooling. Hi power amps now dirt cheap. Experiment on a few - belly up? You got the dB level and the freq. Hey - it's science.. A.

As qualitatively different in how you use them as between a gas stove and a "normal" microwave. Anyway, we once found a roach -- only the once, really! -- and decided to see if we could make it pop. Put it in the mini-nuke for 10 seconds. It just wandered around inside. (Now keep in mind, this thing would boil 8 oz. of water from room temp in less than 20 seconds.) Tried it for 20 seconds. Nothing. "Screw this ... " Two minutes. It just crawled around. Apparently (I discussed this with a biology major later.) many bugs don't have enough water in their body for microwave to work. All their mass is actual stuff, not just hollow cells full of water. (PS: We sterilized the inside of the nuke after the experiment.) This is my sig. There are many like it, but this one is mine.

I suppose there might be some undesirable side effects, but I think it would solve the ant problem. White guys in suits know best - Pat McCurdy
