Jerry, By your questions it appears you are interested in finding out more about eme (Moonbounce) but do not know very much about it. On 2m eme is conducted in the 144.030-144.100 sub-band for CW, and on 144.100- 144.160 for digital eme. Psk-31 is not used and not really suitable. A mode called JT-65 is used for digital eme. It is a narrow-band FSK mode using software and computer soundcard to drive a SSB 2m radio. An excellent article on eme is in the current ARRL Handbook written by Joe Taylor, K1JT, author of JT-65. This will answer many of your basic questions on what eme is and how to get started. http://physics.princeton.edu/pulsar/K1JT/ http://www.n1bug.net/operate/emebasic.html http://www.vhfdx.info/jt65bintro.html One cannot decide today I am doing eme. Where do I transmit? If you have a good satellite or terrestrial 2m yagi and at least 150w you have the basics to start. But there is a lot to learn before one should expect to work eme. There is the basic station setup. Tracking the Moon. Frequencies and procedures used. As you get into it quite a bit to coming up the learning curve. Give yourself at least a couple months to accumulate this knowledge so you are better equipped to try eme.
