I have released version 2.0 of Z90-Control software for the Z90/91
digital panadapters. It is available for download at
http://www.cliftonlaboratories.com/Software.htm..
Of interest to this list is integration with the K2's remote control
interface. The new software adds the ability to click on a signal of
interest and see the actual frequency displayed. A second click will
automatically tune a K2 to that frequency.
Another K2 integration feature recognizes the K2's operating mode and
selects one of three IF frequency offsets. This solves a display
frequency error problem due to the way the K2 handles different modes
with a single crystal filter.
Also integrated for K2 owners is automatic sense inversion; so that
signals displayed on the left are always lower in frequency than those
to the right. Since the K2's frequency conversion scheme is
up-converting on some bands and down-converting on others, enabling this
feature avoids the need to recall upon which bands the frequency display
is inverted.
Note that the LCD display on the Z90 always remains in spectrum analyzer
sense mode; lower input frequencies are to the left of higher
frequencies. The automatic inversion applies only to the Windows display.
Other interesting and useful features have been added in release 2.0.
There is also a new firmware release for the Z91 that speeds up sweep
time about 2:1 by deleting code associated with the LCD.
