Looking for bugfixes? I list them here.

Additions in SdrDx 2.18 (up to 2.18u)

() 2.18... is cooking. Smell that? It's my brain burning.

(35) 2.18u
The CWO display is (again) 4 digits, and the range is back down to -999 ...  999

(34) 2.18u
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.

(33) 2.18u
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

(32) 2.18u
Scope sweep rate no longer affects anything but SCP mode.

(31) 2.18t
The X/Y mode Gain and Q settings are now saved and loaded with program end and start.

(30) 2.18t
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.

(29) 2.18t
The notch displays are now 5 digits to accommodate the notch frequencies reaching 20000 Hz.

(28) 2.18t
BW1 ... BW7 now store and recall the direct-frequency entry offsets which bias the FSU, FSL, CWU, and CWL demodulator modes. This allows storing different center frequency offsets, if you'd like to do that.

(27) 2.18t
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.

(26) 2.18t
Scope trigger controls: Right-click SUN or key function 396.

(27) 2.17s
Custom aux scope colors: Right-click RAT or key function 395.

(25) 2.18s
VFO Suite removed from docs, web page. Use the built-in VFOs instead.

(24) 2.18s
Added key function 394 to clear the main text area.

(23) 2.18r
Added docs to show how to make EX1 through EX4 work under Windows XP. It's not pretty.

(22) 2.18r
NFL state is now saved, and defaults to on

(21) 2.18r
Added / updated 160-190, 13560-13567, and 26960-27280 as Industrial + Part 15

(20) 2.18q
Added the 2200m and 630m ham bands to the internal database, the band indicators, and the <AR and AR> button functions.

(19) 2.18q
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.

(18) 2.18o
When NFL is on, the notch indicators will no longer be drawn in the demodulator bandpass.

(17) 2.18m
Added NFL, 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.

(16) 2.18l
Skipped - the lower case letter "L" looks way too much like a number one.

(15) 2.18k
Recordings can now be pre- or post- noise blanker, IQ balance, etc. See record dialog with Right-click  o 

(14) 2.18j
Recordings are now pre- noiseblanker, IQ balance, etc.

(13) 2.18i
Holding control while clicking SM1...SM4 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 SDR.)

(12) 2.18i
CLK more universally obeyed: VFOs, memories, network commands.

(11) 2.18h
Span memories SM1, SM2, SM3 and SM4 now incorporate the ability to set the grid spacing.

(10) 2.18g
AFEDRI gain in SDR dialog now available to other AFE SDRs than just the AFEDRI (AFE822, AFE822x)

(9) 2.18f
AFE822x VHF/UHF SDR AGC switches and manual gain support added to SDR dialog.
  Mix AGC 
AFEDRI VHF LNA gain (only when   LNA AGC  unchecked)
AFEDRI VHF Mix gain (only when   Mix AGC  unchecked)

(8) 2.18e
AM Demodulator max bandwidth increased

(7) 2.18e
FM Demodulator max bandwidth increased

(6) 2.18d
Key function 392: Squelch increase by one level
Key function 393: Squelch decrease by one level

(5) 2.18c
Key function 391: lists all key functions to "keyfuncs.txt" in the user's home directory in numeric order.

(4) 2.18b
Inverted radio IF documentation added.

(3) 2.18b
I/R renamed to I/RFG

(2) 2.18b
Right-click FM 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.

(1) 2.18a
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)

(11) 2.18u
Some bugs in the Load Band Set operation ironed out.

(10) 2.18t
Further fixes in the rtty setup dialog to do with RHI range issues.

(9) 2.18t
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.

(8) 2.18t
More consistent "Sample rate" nomenclature in the SDR dialog.

(7) 2.18t
In the DMD 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.

(6) 2.18t
PEK was not working.

(5) 2.18t
DMD dialog   FSU  and   FSL  were not working.

(4) 2.18t
Tooltip in error for INL

(3) 2.18r
Fixed tooltips on notch readouts for N9 and NA

(2) 2.18p
-Ri wasn't working when RF notches were on.

(1) 2.18n
Audio notches remained on when RF notches were selected. Now it's either audio, or RF. That was the original design intent. My apologies.

(0) 2.18a
