Basically, I'm planning to use a G90S + GP20 + power supply (20W) for FT8, which should be sufficient. As for SSB, I'm considering joining an association and using a 100W setup afterward.
I'm currently lurking on Xianyu (an online marketplace). If anyone in the forum is willing to sell a G90S, please let me know! 😊
In conclusion, thank you all for your suggestions.😘
