So I got my general and an FT818 to do SOTA/POTA. Using it portable with an external 5Ah LiPo and a HyEnd 10/20/40 end fed. I have yet to make any contacts in the 8 hours total that I've used this. I've tried from a mountain, local park, and a suburban parking deck. Antenna has been hung vertically, inverted-V, and horizontally. I've come up with nothing. Crickets. Silence (which is not golden, BTW). I've tried afternoon, grey line, and round 0200 UTC (SE United States). Any tips for a newb from you seasoned hams out there? I'm going to self-spot and try a few more activations with it but I'm about ready to sell it and go back to VHF, where I've had pretty decent luck with SOTA.
