Because I've been fighting powerline noise, I've become much more aware of the details of what's up there. One thing that I notice at intervals on 3-phase 34.5 KV lines around here is banks of capaci

Well, yes, but in most cases at HF the added receiving gain is not really useful, because your ability to hear is limited by signal-to-noise ratio, not path loss, and the extra gain will just bring u

Why not consider a 3CX1200 for conversions like this? I believe the cost would be less, only one socket, only one chimney, instant-on and a robust grid. Takes more driving power, I know. Is the anode
