|Additions in SdrDx 2.18 (up to 2.18u) |
() 2.18... is cooking. Smell that? It's my brain burning.
The CWO display is (again) 4 digits, and the range is back down to -999 ... 999
The Load Band Set operation in the VFO dialog now disables the dialog controls during the load process; then activates the first VFO once the load is done.
The Windows version now saves and loads its settings using a .ini file; this change has been made because under Windows XP, not all settings were being saved and/or loaded; working on resolving this. Resolved
Scope sweep rate no longer affects anything but mode.
The mode Gain and Q settings are now saved and loaded with program end and start.
The CWO display is now 5 digits to accommodate CWO values from -2000 to 2000. Change 27 didn't work out - I just wasn't comfortable with it.
The notch displays are now 5 digits to accommodate the notch frequencies reaching 20000 Hz.
... now store and recall the direct-frequency entry offsets which bias the , , , and demodulator modes. This allows storing different center frequency offsets, if you'd like to do that.
See change 30, above
CWO now has a range of -2000 to 2000; because -2000 requires a 5-digit display, I changed the reader to only display the value, and not the sign, so as to keep the display the same size as the rest. This may be a trifle confusing, but I think it'll work out. If not, I'll revisit it.
Scope trigger controls: →Right-click or key function 396.
Custom aux scope colors: →Right-click or key function 395.
VFO Suite removed from docs, web page. Use the built-in VFOs instead.
Added key function 394 to clear the main text area.
Added docs to show how to make through work under Windows XP. It's not pretty.
state is now saved, and defaults to on
Added / updated 160-190, 13560-13567, and 26960-27280 as Industrial + Part 15
Added the 2200m and 630m ham bands to the internal database, the band indicators, and the and button functions.
The ham band indications in the database now include US license classes allowed in the various band segments. The codes EAGTN mean Extra, Advanced, General, Technician, and Novice.
When is on, the notch indicators will no longer be drawn in the demodulator bandpass.
Added , which locks the RF notch frequency in the case of demodulator tuning. This allows you to set up RF notches and they will stay where you placed them while you tune. If you change the center frequency, they will re-lock to the demodulator bounds. The application that made me do this was tracking the doppler shift on an ISS transmission; the birdies stayed in one place, but the signal didn't, so this allows tuning in such a case while keeping a "finger" on the notch frequencies.
Skipped - the lower case letter "L" looks way too much like a number one.
Recordings can now be pre- or post- noise blanker, IQ balance, etc. See record dialog with →Right-click
Recordings are now pre- noiseblanker, IQ balance, etc.
Holding control while clicking ... will set the span to the maximum span for the current sample rate, and the grid setting to either 10, or the last selection made in the SDR setup dialog (accessed with .)
more universally obeyed: VFOs, memories, network commands.
Span memories , , and now incorporate the ability to set the grid spacing.
AFEDRI gain in SDR dialog now available to other AFE SDRs than just the AFEDRI (AFE822, AFE822x)
AFE822x VHF/UHF SDR AGC switches and manual gain support added to SDR dialog.
AFEDRI VHF LNA gain (only when LNA AGC unchecked)
AFEDRI VHF Mix gain (only when Mix AGC unchecked)
AFEDRI VHF VGA gain
AM Demodulator max bandwidth increased
FM Demodulator max bandwidth increased
Key function 392: Squelch increase by one level
Key function 393: Squelch decrease by one level
Key function 391: lists all key functions to "keyfuncs.txt" in the user's home directory in numeric order.
Inverted radio IF documentation added.
I/R renamed to I/RFG
→Right-click allows you to set the DC response of the FM demodulator. There are key functions for setting the response directly, and for opening the dialog. These key functions are unassigned by default.
AFE822 phasing methodology changed. Smoother, faster, cleaner. Credit to Chris of Black Cat Systems for the idea.
|Bug fixes in SdrDx 2.18 (up to 2.18u)|
Some bugs in the Load Band Set operation ironed out.
Further fixes in the rtty setup dialog to do with range issues.
Changed how the VFO loader parses saved VFO files; negative numbers were breaking parameter loads, which caused reload of Max dB parameters, for instance, to fail.
More consistent "Sample rate" nomenclature in the dialog.
In the dialog, the switch between Gain and Knee consequent to switching AGC on and off was not working properly, and I/RFG was not updating in all cases.
was not working.
dialog FSU and FSL were not working.
Tooltip in error for
Fixed tooltips on notch readouts for and
wasn't working when RF notches were on.
Audio notches remained on when RF notches were selected. Now it's either audio, or RF. That was the original design intent. My apologies.
