An inductance or capacitance can easily be calculated by substituting the known
values into the above equations.
The oscillation coils supplied with your DM-81 are useful as the known inductor.
Their inductances are
BAND INDUCTANCE
A 1250 µH
B 160 µH
C 39 µH
D 8.4 µH
E 1.2 µH
F 0.22 µH
G 0.047 µH
In addition to all these applications, your DM-81 is usable in place of a receiver
local oscillator in repairing or alignment, and is effective in other services as well.
Also, your DM-81 can serve as a BFO for a receiver without one in receiving a
CW or SSB signal. It is useful in a wide variety of situations. By fully
understanding the principles of operation your DM-81's capabilities may be
extended to other applications.
For an additional source of general information, the radio amateur's handbook is
recommended.
