PowerSDR-IF v1.19.35 Installation & Setup
If you are running Vista or Windows 7, it is wise to be logged in as Administrator, or another user with admin privileges. If you are the only user, this is probably the case for your normal login. PowerSDR/IF requires .NET Framework 3.5 SP1 (Service Pak 1). Update to this version if necessary before installing PowerSDR/IF. Use Add/Remove Programs in the Control Panel (or Programs & Features, depending on OS) to check installed version. The latest version can be found at Microsoft.com.
The PowerSDR-IF v1.19.35 program can be downloaded at

Click on the
Setup menu in
the upper left of the program. This will open up the setup screen, as
below. Most if not all of the settings will match this picture. If not,
them to match the picture. It is imperative
“Receive Only” be checked.
Select rig type to match your rig.
Choices include K3, Yaesu (FT950/2000/5000), TS940S, TS950S and HRD.
The HRD choice assumes that HRD is connected to the rig and provides a
DDE link to HRD. This choice provides an wasy way to connect to rigs
that are not directly supported. Set
port number to match the port that your rig is connected to unless you
are connecting though HRD. This can
be a real serial port, a
USB-to-serial adapter or a virtual port such as those created by
LP-Bridge, LPB2 or microHam
Router. It is smart to get PowerSDR/IF working
directly with your rig before trying it through LP-Bridge or LPB2. Set
baud rate to the fastest that your rig supports, and set your rig to
match. Leave other
at their defaults. If your rig is a K3, you have the option of syncing
the RX Filter
width in PowerSDR/IF with the K3. This feature has some limitations,
and you may not like
it. With a K3, it is normal to also poll for IF Frequency, which makes
mode offset tracking automatic.
Click on Collapsible
tab. Collapsible Display is a new feature that allows the user to fill
PowerSDR window with the panadapter (or waterfall or Panafall),
covering up all
the extraneous buttons and controls. Additional controls can be “added
into the display as desired. Check the additional items that you want
whenever displaying collapsed view. Click OK to close the
Click Start in the upper left corner of PowerSDR/IF. You should now see the K3 VFO frequencies in PowerSDR/IF, and you should see signals in the panadapter, as shown below. The display defaults to the “fill” style, where the graph is filled down to the noise floor. This can be changed to the style shown by going to the Setup>Display tab and un-clicking the “Fill” selection. If you have speakers connected to the E-MU, you should also hear sound from them. If not, check to see if the Mute button is lit in PowerSDR/IF. If it is, click on it to un-mute. Listening to PowerSDR/IF is of course optional. It can be used solely as a panadapter display and interface if you choose.
Setup for Rigs Without CAT Interface
To display a relative frequency scale instead of actual rig frequency, check the “Show Freq Offset” box in the PowerSDR Setup tab depicted above. The resulting display will appear as shown below. Tuning the rig will cause the signals to shift. The red line represents the center of the IF passband, ie. frequency the rig is tuned to.
PowerSDR-IF v1.19.35 Collapsed View
Below is the normal (Expanded) PowerSDR/IF Stage display. We have added color box overlays to help identify the various control sections. The sub-receiver is activated in this picture. Your view may be slightly different, depending on how you size the window. PowerSDR-IF can be sized from 1024x768 up to the full screen resolution of you monitor. As you zoom up the window, the pan display becomes a larger percentage of the window. Most of the receive controls are active for LP-PAN use. The transmit controls only work with FlexRadio hardware.
PowerSDR/IF Stage provides several ways of tuning, and supports both VFO A and VFO B of the K3.
Tuning of VFO A can be accomplished in these ways…
- Using the tuning knob on the K3
- Clicking and dragging the pan display for large excursions
- Using the mousewheel for fine tuning. The tuning step size is set in the box between VFO A and VFO at the top of the program.
- Point-and-click is invoked by right-clicking in the pan display to activate a yellow cursor. Position the cursor over a signal and left-click to tune to the signal.
- Enter a frequency directly into the VFO A window
Tuning of VFO A can be accomplished in these ways…
- Using the VFO B tuning knob on the K3
- Clicking and dragging the blue sub-RX passband and dragging it
- Using the mousewheel for fine tuning. The tuning step size is set in the box between VFO A and VFO at the top of the program. Hold Ctrl while using the mousewheel to tune VFO B
- Point-and-click is invoked by right-clicking twice in the pan display to activate a red cursor. Position the cursor over a signal and left-click to tune VFO B to the signal. When the red cursors are on, mousewheel tuning adjusts VFO B.
- Enter a frequency directly into the VFO B window
the WU2X website… “As an additional tip here, Logitech has a series of
that have something called "Hyper Scroll Wheel". These are mice with
a weighted mouse wheel. The wheel does not have detents, it freewheels
spin it - just like a weighted VFO knob!
Coding guru Chad has implemented a time based queue so that when
spin the weighted mouse wheel, the tuning of the external radio is
smooth. As it was, the free spinning VFO
knob in PowerSDR/IF Stage would overload the external rig with CAT
changes. We really dig the hyper scroll
Logitech mice and highly recommend them.”
Here is a summary of the various controls that are supported in this version of PowerSDR, referenced to their location on the screen.
VFO A, VFO B... Display the values of the rig's VFOs. You
can directly enter frequencies here, but this is rarely necessary. The
small boxes in each VFO window indicate the TX/RX assignment of
the VFO. The lower box indicates the band segment that is tuned, based
on IARU Region 1.
<>MUT, MON… The
term mute in context
with PowerSDR means the muting of the audio output of PowerSDR when
transmitting. If you use LP-PAN only as a display, mute has no real
Normally, mute is a software function handled by LP-Bridge and
PowerSDR. It can
be disabled by selecting MON in PowerSDR if you want to hear your
signal. PowerSDR always displays the spectrum of your low level
signal. Hardware mute is also provided by LP-PAN, but will not be
most operators. In general, LP-Bridge will provide fast enough muting
muting in software for VOX or semi-break-in CW keying. This is not the
with HRD, which has a sizable delay. If you require faster or special
contact TelePost support for suggestions on using hardware mute.
X2TR… Not used
Red Dot, Green Arrow…Controls the sound recorder. Clicking on the red dot starts recording of the entire panadapter passband. Clicking on the green arrow allows playback. During playback, you can tune around anywhere in the recorded passband.
AF…Controls overall audio monitor level
AGC-T… Sets the AGC threshold
Drive… Not used
AGC/Preamp… Sets AGC speed and preamp setting, only for PowerSDR. If you set up the Aux CAT interface in LP-Bridge, the preamp setting will follow the K3
Squelch… Adjusts squelch… mainly useful for FM, but active in all modes.
BCI rejection… Not used
Split / A>B / A<B / A<>B… Self explanatory. Other controls in this group are not implemented.
NR… Digital Noise Reduction (PowerSDR Only)
ANF… Automatic Notch Filter (PowerSDR Only)
NB, NB2… Digital Noise Blankers (PowerSDR Only)
SR, BIN… Not used
Display Selector… Determines what is displayed in the graph window. Choices are Panadapter, Scope, Phase, Spectrum, Waterfall, PanaFall (PowerSDR Only)
AVG / PEAK… Provide averaging or peak hold behavior for the signals in the panadapter. Settings are on the Display tab in Setup. (PowerSDR Only)
MultiRX / Swap… Controls the sub-receiver (PowerSDR Only).
Sliders determine the
routing and mixing of audio from the main and sub-receiver. When Sub RX
there are two passbands displayed… green for main and blue for sub.
passband is linked to VFOA and blue is linked to VFOB.
Mode Specific Controls… Panel changes depending on Mode setting.
CW Pitch… The most important control is CW Pitch, which only appears when a CW Mode is selected. Set to match your K3 CW Pitch setting.
Show TXCW Frequency…When CW mode is selected, checking the "Show
TXCW Frequency" box places a vertical yellow line on the tuned
frequency. This is particularly helpful
when working split and looking for an open frequency in a CW pileup.
Band… Selects band for both PowerSDR and K3. This can be used as a quick way to change bands.
Mode… Selects mode for both PowerSDR and K3. Modes not supported in K3 are ignored by K3. Modes such as DRM require additional software to decode. SAM is Synchronous AM mode.
Filter… Selects PowerSDR DSP filters in both PowerSDR and K3, unless filter syncing is disabled in SetupIF>IF Frequencies.
Width and Shift…
Follow passband indicator on
the pan display. If you checked the “RX Filter Width” box in SetupIF,
will synchronize with the DSP settings on the K3, regardless of whether
are made in PowerSDR or the K3. But there are limitations to the use of
since Shift cannot be linked. This can cause erratic behavior,
you try to adjust the lower side of the passband. You can temporarily
the link by clicking on “Var2”, or permanently disable it in SetupIF.
RX Meter… allows several different modes for the S-Meter to be selected
Pan & Zoom… adjusts the portion of the passband that is displayed in the panadapter. Wide display is far left in zoom bar, PAN should be centered.
In addition to the highlighted areas, there are several other controls which are useful. They are accessed in the toolbar at the top of the program.
RX EQ… enables graphic equalizer for PowerSDR receiver. The equalizer can be set in the Equalizer pull down menu at the top of the program.
Memory… save popular frequencies for recall.
