What, no shortwave?
You have asked quite a few questions, which we combined with other 
respondents hopefully can answer.
 DD> What's the diff between AM / FM.
AM = Amplitude Modulation
FM = Frequency Modulation
For a detailed technical explanation, please refer to an electronics 
xtbook.
 DD> HOw come FM seems to be a much stronger signal , and can go in
 DD> Stereo (AM Cannot) , but then why can I get AM stations from like
 DD> OHIO and places far away at nightime?
Propagation changes between day- and nighttime. Your reception area increases 
dramatically after sunset as you have noticed.
 DD> SO there are other transmissions outside the regular 530-1700
 DD> kHz.
You better believe it.
 DD> If you're able to get to
 DD> 1700 kHz and start again at 88MHz , there must be an imbetween .
Elementary Holmes, from about 1800 KHz (1.8 MHz) to 30 MHz you have the 
Shortwave Bands. Above that are various TV Channels, and the 6m Radio Amateur
Band.
 DD> since it's all in Hz's.
 DD> and therefor why wouldn't AM get stereo , since it's also Hz.
You need a special receiver for AM Stereo and the station, of course, has to 
also broadcast in Stereo.
 DD> And why is AM effected and goes all screwy when I turn on my
 DD> computer and FM doesn't , it must be the Hz level I guess?
Interference, your computer (and mine) are not very well shielded and 
generate RF Noise which the radio picks up.
 DD> SO where can I pick up a radio that will pick up these
 DD> frequencies. ?
Local Ham radio stores, or places in Toronto that you can order from. I would 
not be surprised if North Bay has a yearly fleamarket where you could look 
around for different receivers.
 DD> And what's the cost?
Depends on what exactly you are looking for - from hundreds to thousands.
 DD> What kind of transmissions will you recieve?
Again, depends on what you buy. Ham Radio, Marine and Aeronautical, 
International Broadcasters, Police, Fire, Ambulance, AM- FM, Satellites, the 
list is endless.
 DD> Anyways I'm going on too long here , hope someone can help me
 DD> out?
We are trying...
 DD> ANd what is Ham Radio?
If you have Internet access, go to rec.radio.info and you will find detailed
explanations and FAQs. In your Newspaper store look for QST- or CQ Magazines, 
check out your local library for those as well and any radio related books.
Good luck,
