[Milsurplus] BC-611 Coil Info?

[Al Klase]

Robert,

FWIW, the antenna coil measures 81 uH and the tank 37 uH in my 3885 BC-611.

Since you're only moving 27%, you might get away with just hanging a 
little extra capacitance across the tank. The antenna loading coil is 
another matter as it's effectively in a series circuit, so it need more 
turns.

Good luck,
Al
