WiNRADiO G33DDC User’s Manual

Such calibration can be done either manually, by entering a correction factor
for the reference oscillator directly, or using automatic calibration against a
known reference signal.
To calibrate to a peak, simply tune the receiver to a known reference
frequency (presuming a reasonably strong and steady signal). The frequency
difference between the peak and the receiver’s tuned frequency will be shown
as
Peak offset
.
To calibrate the receiver to the peak frequency, click on
Calibrate to peak
. If
successful, the peak offset will show as zero. Press
OK
to complete the
process.
Hand-Off Receiver
The
Excalibur Pro
receiver software includes a useful function which allows
users to utilize a WiNRADiO
G313
receiver as a hand-off or recording
receiver. The WiNRADiO G313 receiver is a high-performance software-
defined narrow-band receiver with superior quality crystal filters and a
significant reserve in sensitivity, and so able to provide a better signal-to-noise
ratio than the
Excalibur Pro
on very weak signals.
When the G313 receiver is connected, selecting the
Hand off receiver
option
under the
Options
top menu bar allows the
Excalibur Pro
to pass the tuned
frequency, mode and bandwidth information directly to the G313 receiver. For
the G313 receiver to become available to the
Excalibur Pro
, it must be fully
connected, and the G313 application software running.
This feature may be useful if a frequency of interest is found and you wish to
record or monitor it, and then tune the
Excalibur Pro
to a frequency outside the
currently selected DDC band.
Audio from the G313 receiver will normally be presented to the stereo mixer
system, although with the
G313i
model (internal PCI-card version), it may be
more convenient to use a separate speaker connected directly to the audio
output available on the PCI card.
