Thank you all for the replies.
I'm still curious what power level a 5 amp rated (as Karl suggests)
inductor would be appropriate to use in. A simplistic I squared R
calculation yeilds over a KW at 50 ohms, but I don't know what impact
skin effect or circulating currents have.
I also found contradictory info on the BC-375. One source says it a
600-800 watt input transmitter, but other sources suggest a much lower
power unit. I'm inclined to believe its in the 100 watt class given
its appearance.
