What do yo do with your ham radio? Is it just like talking to your buddies on the phone?
Yes and no. Amateur radio is about 100 hobbies with a radio related thread running thru all of them..Yes some people like to just get on and talk to their mostly same buddies all the time usually on the same frequency. Not so interesting for me. Some hams like to build equipment, or antennas or station accessories. I do some of this. Some like to talk about their projects and some hardly ever get on and talk with anyone more than just testing the project they just built. This is similar to what you see on here with the guys construction projects. Some are focused 100 percent on public service, and have no interest in conversing with anyone, except in a disaster to pass radio traffic. I have done this, and would again, but it is not my primary focus Some are DX (distance) chasers, working toward one or more of the many certificates and plaques, and try to work as many countries, regions, states etc on various modes and bands. I have done my share, but I don't really care about the awards or plaques or QSL (confirmation) cards for that matter.
Some only work VHF and above frequency, and enjoy the extra challanges that come with making things work at those more limiting frequencys. (microwave techniques in building equipment can be more challangeing)
Some just like to get on and make new friends every time and chat a while with them if they are interesting to them or not so long if they are not.. I fit in here for quite a bit of my operating. I also like the computer based digital modes, which is much like what I am doing here, exchanging information thru a keyboard, but without infastructure. When you are on HF and you are communicating from you station thru your wire or aluminum antenna to his antenna and down to his station there is no supporting infastructure like you have here. It is just you, him and the natural ionosphere. If both of you are on battery power, and/or solar charged, the world could go to heck in a handbasket and you could carry on. Not so much here as you know with our wifi, home routers dsl or cable borne services, the huge fiber backbones, gateway routers, servers etc. All of the million things that make up the internet and this service.
Anyway I have touched on only a few aspects of Amateur Radio, and I may not be the best spokesperson for this, but I have been into it since 1971. Others (many) on here (and you know who you are

) please feel free to jump in with your views on Amateur Radio. It is very diverse, almost like a bunch of tractor owners.
Hope this helped a little to explain a difficult to explain and diverse subject.
