Assembled from various sources, a complete set.(Sparse)The main structure of the shortwave radio stations was also becoming clearer.
- 5-meter boom antenna - GP
What's this called again (the antenna mount)?

Radio: ICOM IC-706 (borrowed)
Although it covers the entire frequency range, FT8 seems less convenient (?).
Mixed-key, borrowed
Power supply
What about using a modified 13.8V (or native 12V) server power supply inside?
If I were using it outdoors, what kind of battery would I typically use? Would a lead-acid or lithium iron phosphate (LiFePO4) battery be better (although a 100W power battery might be difficult to find)?
Thank you very much to all the seniors for your valuable advice on my first foray into shortwave equipment.
