lets think about this.
how much power is your standard kitchen microwave oven?
Range is 700watts for a small, apartment, bachellor sized oven for zapping
pizza or left over chinese take out. Upper range is 11 or 1200 watts for a
large family sized oven for making serious meals.
On average, acording to wikipedia, a modern microwave oven has an efficiency
rating of 64 percent...so 64 percent of the total listed rating.
at a 700 watt rating, this would be about 448W. At a 1100 watt rating
its around 704W.
You could probably heat one precooked hotdog in a 700 watt microwave oven in
about 2 minutes or so....perhaps less, maybe 30 seconds to achieve a nice
hotdoggish split.
This is precooked, so there is no need to actually cook the meat.
Cooking real meat, like chicken, beef, pork, whatever, probably 20 minutes
plus to get it properly cooked, though still rare. this would be at the 700
watt range.
Now, imagine you have a 1.2GHZ transmitter...there is no cooking cavity to
bounce the RF around in to consentrate it's radiation towards a central
point for cooking purposes. You could use a wave guide to consentrate the
RF into a narrow beam though.
You would need at least 448 watts of RF, at 1.2GHZ to think about cooking
the meat, and would have to key down for probably 15 minutes minimum to
achieve enough heat to cook the inside of the meat...meanwhile, you would
have to cool the amplifier with a pretty large water cooling system...not to
mention higher power levels.
The ts2000 puts out 10 watts on 1.2GHZ...
we won't even get into types of modulation and carier and all that kind of
stuff that doesn't factor in when refering to microwave ovens.
They use a magnatron to convert power from a transformer into RF which is
then sent through a wave guide into an enclosed cooking chamber.
So, in practical terms, you could never cook anything even with a waveguide,
and an inch away with 10 watts out of the ts2000....well, perhaps you could,
but it might take weeks.
it would be like trying to cook a hotdog with your wireless internet router,
which is close to the same frequencies used by residential consumer level
microwave ovens.
With high power and a wave guide at 2.4 gigs, you can heat a glass of water
apparently, but I've never actually seen or read proof of any ham operator
doing this.
it takes a huge amount of cooling to operate any kind of power on 1.2GHZ
with a modulated RF signal.
Most guys that use 1.2GHZ amateur frequencies with an amplifier have pretty
large water cooling systems.
Microwaves use a cooling tube, and the RF is not modulated as we know it in
communications terms.
So the short answer is, you can't cook a hot dog with an amateur 1.2ghz
transmitter.
