Simplex Radio means talking to other people on a single radio frequency without the use of repeaters.
5 Watts and a well-placed antenna is all you need. More power works better, but it's all in the height and efficiency of the antenna.
HAVE FUN...make new friends
LEARN...good Simplex takes practice (and a few bucks)
SERVE COMMUNITY...if an emergency arises you'll all be prepared
K.I.S.S. .... Keep It Simplex, Stupid!!
All it takes is a commitment to build a network of licensed Hams:
From the ARRL Operating Manual (2003):
Chapter 3, FM The Friendly Mode, in a paragraph marked "Go Simplex" it says, among other things:
"After you've made a contact on a repeater, move the conversation to a simplex frequency, if possible. The function of a repeater is to provide communications between stations not able to communicate directly because of terrain or equipment limitations. If stations are able to communicate without a repeater, they should always use simplex whenever possible so the repeater will be available for stations that need its facilities." p.3-10

Biggest and baddest advocate for Amateur Radio in the U.S. and possibly the World:
You don't have to be a member to access many of their resources. Membership is indeed worth it, though.
Don't be surprised that 146.415 isn't on the list of "normal" Simplex Frequencies, but that's the beauty of Ham Radio: WE decide where to operate on the approved portions of the band.
Many factors affect radio signals, but the important ones are:
See formula below for calculating line of sight distance for radio waves.
The formula, of course theoretically, for how far your signal travels over the face of the earth:
Line-of-sight = Square root of (2 X height of your antenna) PLUS the Square root of (2 X height of 2nd antenna)
Or, if you're bad at math, use the calculator here.
Sounds like a medical condition, but this link will give you the relative (to you) direction of any other station to you so that you know where to point your directional antenna.
