LY4SA Depends on conditions where you use it and what frequency. For 2m band you have to be licensed HAM. For PMR I've tested in urban conditions and it is about 2km

LY4SA true measured power out is about 7-9W. Battery capacity is very large and enough for a long time, I don't think you need spare batteries, but it's up to you.

LY4SA My guess - VHF and UHF are nor filtered by switch and goes through while HF is filtered by internal circuit. Open your SDR switch and try to move short black jumper to other position then it is now. Hope this helps
