Previously, it was said that using high-power equipment was the way to go, but now...
- The budget is sufficient; models 7300 and 710.
- The budget is sufficient, but not quite enough; 891
- The budget isn't sufficient, so I would recommend the G90S/G90N. Pair it with a good antenna (like a full-size GP or a standard V), and start with FT8 – that will also work well.
While a QRP radio might not be ideal for beginners, if your budget is limited, you can initially focus on using it with a 5W power FT8 mode to communicate. This setup is also suitable for beginners and allows you to learn the communication patterns. Later, you can gradually upgrade your equipment as needed.
