HX-11

[Garey Barrell]

Stan -

The DX-60 has the identical filter, and it is shown as 0.44 uH, 0.5 uH, and 0.44
uH.  These are more logical numbers, and I believe the confusion comes from the
use of "MH" for microhenry back when the HX-11 was sold.

The "partial" manual on BAMA has the specifications, installation and operating
instructions.
