Additions up to SdrDx 2.13y
as of 2.13y, SdrDx obtains run times in seconds for each installation during version inquiry. This identifier is used to both get an idea of application stability (a new runtime isn,t saved if SdrDx crashes, so I can see likely crashes by checking if run times update between inquiries) and to help get an idea of the level of interest in the software. If the installation is never given access to the Internet, it simply won,t be able to learn, and report to the user, what the latest software version is. There is no effect on the program,s functionality.
in 2.13x, NBL now resets the SNF references.
in 2.13w, the general parameter adjustment window (previously titled "Tweakerizer") now has a legitimate title.
in 2.13w, I completely re-wrote the SNF code. Again. It is now faster, more efficient, and better looking. This was an extremely gnarly technical challenge, and I have to say I,m delighted with the solution I arrived at. I want to encourage everyone to (re-)try SNF Please take the time to right-click the button and experiment with the control parameters; I can just about guarantee you that your time will be well-spent doing so. Remember that this feature interacts with the db level and step controls, as well as I and C — adjust for a good looking waterfall first, then work with SNF
in 2.13v, SdrDx obtains a unique numeric identifier for each installation during its first successful version inquiry to see what the latest available version of the software is. This identifier is used to prevent taking statistics multiple times for dynamically assigned IP addresses. If the installation is never given access to the Internet, it simply won,t be able to learn, and report to the user, what the latest software version is. There is no effect on the program,s functionality.
in 2.13v, Negative spectrum excursions are now arbitrarily reduced when utilizing SNF
in 2.13v, You can now press DOW twice. When green, it acts as it used to - one white line down the waterfall. Next click, when blue, it draws two black lines to either side, this makes it more visible. Next click is off again.
in 2.13u, Variable threshold and smoothing sliders for SNF via right-click on SNF This obsoletes the previous use of ANF to activate a single-control dialog.
in 2.13t, Sends lowd:X and highd:X over UDP and TCP when demod bw is changed
in 2.13t, Adds variable threshold and smoothing sliders for SNF via right-clicks on SNF and ANF
in 2.13s, < and > pan the center frequency by the span width.
in 2.13r, I reworked some of the waterfall code for a subtly smoother display. Affects both the spectrum waterfall and the audio waterfall. You may find that some re-adjustments of the C and I sliders are called for, and possibly even some palette editing.
in 2.13p, if ZOO is on, then  O and  P act to zoom in and out on the demodulator frequency. If ZOO is off, then  O and  P only change the span.
in 2.13o,  O and  P control (S+ and S-) span from keyboard.
in 2.13n, SdrDx now generates macro:1 through macro:25 messages when F1 though F15 or 0 through 9 are pressed (or clicked on the GUI) when shift+control are both pressed.
in 2.13m, SdrDx now broadcasts cfreq:X mode:Y when the center frequency control value is modified
in 2.13k, the vertical grid may now contain up to 41 index points.
in 2.13j, the sample rate of the output audio has been changed from 48 kHz to 22.050 kHz. Maximum audio bandwidth within SdrDx is about 10 kHz, so a 22 kHz sample rate should cover all cases. It remains to be seen if this causes problems with external software such as Dream, Multimode, or FlDigi. If you experience problems processing SdrDx,s external audio, please report them ASAP.
in 2.13i, the bandwidth of the demodulator has been added to the topmost status line.
in 2.13g, ^ Q and ^ V now perform IF shift. This allows the Powermate knob to perform the shift.
in 2.13g, Adds keyboard-commanded IF shift (without passband compensation) in USB, LSB, FSU, FSL, CWU and CWL modes. To shift up, press ^⇑ &UARR; . To shift down, press ^⇑ &DARR;
in 2.13g, BW1 through BW7 preset bandwidth memories added. Presets are visible when hovering mouse over buttons; you can store new values by either pressing Shift while clicking the bandwidth memory, or STO prior to clicking the bandwidth memory. These are saved and restored across application invocations. LEDs light up white when bandwidth is set identical to memory; but if bandwidth is the same, yet shifted up, matching bandwidth LED(s) will light up red instead. Likewise, if bandwidth is the same, yet shifted down, matching bandwidth LED(s) will light up green.
in 2.13f, ↑^M sets all ten available general purpose spectrum markers to span the current demodulator bandwidth.
in 2.13f, ^M sets one of ten available general purpose spectrum markers.
in 2.13e, TRK frequency calculations adjusted. Hopefully for a little more accurate readout.
in 2.13e, SAM now remembers last-set bandwidth in LSB, USB or SDB and moves that bandwidth between the modes.
in 2.13c, SAM and ↑S now switches between Synchronous DSB, USB and LSB when pressed repeatedly.
in 2.13b, CON has been added. This turns the clock on and off.
in 2.13b, MON has been added. This turns the s-meter on and off.
in 2.13b, SON has been added. This turns the analysis scope on and off.
in 2.13b, MTI has been added. This enables frequency setting tooltips for the memory buttons to remain active even when TIP is off.
Mechanism for adjusting s-units replaced. S-unit adjustment now also affects baseline for graticule s-unit rules.
in 2.13b, CAL added to backstop the sometimes unusable ^ D (moved to Right-click LPF and Right-click HPF)
in 2.13b, the brightness range of GRT has been doubled.
in 2.13b, SsM has been added; this displays a horizontal set of rules on the spectrum that provide a reference matched to s-meter readings.
In 2.13b, the memory buttons will now show the frequency stored in them when TIP is on. (tooltips)
In 2.13b, the TCP command frontself:0 has been added. This brings the SdrDx window to the front and activates it.
In 2.13b, the TCP command rmute:x y has been added. This reduces the RF signal amplitude when x is 1, by multiplying it by a number y which can range from 0.0 to 1.0. rmute:0 1.0 turns the feature off. rmute:1 .001 reduces the RF by a thousandfold.
Behavior change: In 2.13a, shifted cursor keys (,,,) and quick-tune buttons (<10,10>, <50,50>, <100,100>, <500,500>, <1k,1k>, <5k,5k>, <10k,10k>, <9k,9k>) now scroll the spectrum / waterfall when the demodulator region approaches the span edge.
2.13y Fixes
in 2.13z, bug in detecting SDR type was fixed.
in 2.13u, bug in SNF not allowing gradual smoothing of negative excursions was fixed.
in 2.13q, bug in  Z and  X (slide center frequency) fixed.
in 2.13h, IF shift clamped to prevent inadvertent adjustment of bandwidth to to clipping at bandwidth limits.
in 2.13d, bug where pulling sliders changed SAM mode fixed.
