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.
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.
