### error on my part. L5 is only used on 80m. L7 is used on 160m only.
Both are part of the pi portion of the PI-L network..and both are
powdered iron toroids.
L6 is the tapped toroid, and is the L portion of the PI-L network...used
on1.8 to 18 mhz. L10 is used on 18-30 mhz....and tapped for 18-24
mhz..... and also 24-30 mhz. L10 is just a tapped L coil...and not a
toroid.
