old school hobbiest

hello out there. Im trying to get back in the loop as i have been out of the sat community for some time. So if anyone can direct me to some help with my dm500 for 28.2 channals that would be great. soft & firm stuff. A mate of mine set it up (something with gemini) like 4 yrs ago, so im going to need to start from the beginning. I appreciate the help. Also and new recievers out there that are better and easier and friendly please direct me. Much appreciated Thanks.
