Well, the main idea is to transmit audio over 100 km/62 miles of distance. The transmission would be in straight line without any physical object that can interrupt the transmission. I thought a satellite dish would be a good option because they transmit and receive data to large distances. But any other option that anyone suggest for the same goal will be appreciated. I won't use a satellite, but I will use terrestrial to terrestrial communications.
Technically, you can use transponders in the 144 MHz- (2 metre) band of amateur satellites for such experiments. It WILL NOT meet commercial requirements. It will be periodic in availability.
You can link up with radio amateurs to get more info on these.
That is your problem, there are likely no available channels. You cannot just put a 62mi data link on the air without spending ~$10K in legal and licensing fees. You might be able to rent a subchannel on an existing terrestrial link.
Hams routinely do 100km GHz links, but that cannot be used for any commercial purpose, nor can music be transmitted.

I didn't know that there is the possibility to rent a channel. Well, I can ask with radio amateur. But as I'm reading your posts I see that I've to use a very high frequency (Ghz) to transmit signals over long distances.
No, I just had a 1hour conversation with friends ~1000km away on 7.135MHz. I routinely talk to hams on 146MHz using a mountain top repeater that is >150km from my station using just 1W of output power...
Look at a path loss calculator **broken link removed**. Play around with it.
I want to do a project where I use a satellite dish to transmit radio using FM or other modullation that you recommend.
It's like walkie-talkie but using a satellite dish. I don't want to use other system, I want to use satellite dish.
Yeah, and I want to communicate with a dead relative using a single germanium transistor transmitter powered by a watch battery fed to a coat hanger antenna.
Which channels are legallly available for amateur use in your jurisdiction? Which country are you in? In most countries radio transmission is highly regulated so that radio interference between legal users is avoided. Your presence on the airwaves would be easily detectable by the Authorities.
@HiTech
Sounds perfectly doable. But what will you use for reception
