[Boatanchors] Choke info

[StephenTetorka at cs.com]

Hi all:

Found some helpful choke data in a 1930 QST.

For 30 Hy:
500 ma = 130 ohms
300    = 155
150    = 250

For 20 Hy
500 ma = 105 ohms
300    = 140
150    = 210

For 10 Hy
500 ma  = 65 ohms
300     = 80
150     = 125

For 6 Hy
500 ma = 50 ohms
300    = 60

Thus, my reading of 170 ohms and reading a ?5 number leads me to conclude that my 15 Hy choke has a rating of 0.25 Ma.

Thanks to all for the helpful and interesting replies.

Keep them Glowing,
Steve
