The
Model DD-103 Universal Digital
Dial works with any receiver and most transmitters by counting only
the
VFO signal. SEE RADIO LIST
It even works with receivers that have some reverse
tuning bands like the R388 or Drake 2B. All of the VFO and band
information for many
receivers and transmitters is pre-programmed into the display's memory.
This allows the operating frequency to be displayed by counting only
the VFO signal. There is also a manual program mode that lets you
program the dial for any receiver or transmitter (up to 32 bands) that
is not pre-programmed. Each band can be individually
calibrated to allow for crystals that have aged or any other error no
matter where is comes from, to 10Hz accuracy. 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. There is also a BAND CTR (COUNTER)
that has
no offset, that is available any time so the unit can double as a bench
counter up to 40MHz. The DD-103 uses a TCXO for it's reference
which provides very high accuracy and stability. Signal and power
cables are included. Power is from the radio 6.3VAC filament supply or
12VDC can also be used. Installation usually requires no soldering or
technical
knowledge, depending on the radio.
