The
unit has two operating controls, a BAND switch,
and a MODE control. All of the VFO and band offset
information for many receivers is stored in
the display's memory. See Radio List This allows
the receive frequency to be displayed by counting
only the VFO signal. Either 100Hz or 10Hz
resolution is switch selectable. Each band can be
individually calibrated to allow for crystals that
have aged or any other error, to an accuracy of
10Hz. The calibration information is also stored
in memory, so that any time you return to that
band, the display is automatically calibrated. You
only calibrate each band one time. The ESP DD-103
has a band that is always available for use as a
bench counter. High accuracy and stability is
achieved by the use of a TCXO refference
oscillator. Included is a tube shield pickup for
easy installation on some receivers. Others
may require connecting to the oscillator section
of the tuning gang capacitor. Cables are
included. A power supply is included if US
type power can be used. The DD-103 uses a
backlighted LCD display and is 2"H X 6"W X 4"D.
The Tube Shield
Pickup and Power Supply are not included with
the Custom Cable.
