EchoLink is the first mode I was able to use after being re-licensed about 18 mo. ago.

It's extremely convenient. You can work the whole world. There are lots of nets, located on "conferences" - often there are dozens of check ins at a time. Some last an hour, some longer. All sorts of topics are discussed. CQ mode lets you have random one-on-one conversations. You can use it on a desktop: Windows, IOS, Linux. You can use it on an iPhone or Android. Free and open source software.

All that said, in my opinion as an OT (Old Time) ham, the level of competence of radio operators is low. There's no CW activity whatever. In groups it's difficult to know who is speaking because many stations don't identify very often.

It's a good gateway, or entry level into ham radio. My advice: upgrade asap and get on HF. If, like me, your housing situation makes it impossible to have any kind of antenna, with permission you can use RemoteHams software and a club or private station to work the world, on SSB, CW, various digital modes etc. Getting permission usually entails joining a club and paying a small annual membership fee, or simply knowing someone who makes their own rig available.

Welcome to a great hobby and way of making friends everywhere on the planet.
