The WinPSKX ActiveX Control in Action
This screenshot shows Moe Wheatley's original WinPSK program modified
to use the WinPSKX ActiveX control in place of the original data display code.
This modification was based on the V2.09 version of WinPSK.
The differences between my ActivePSK program and Moe's WinPSKX are:
- The zoom control has been removed. This is implemented a bit differently in
the WinPSKX ActiveX control, and for this reason no longer needs to be manipulated
in the application.
- I replaced the display type tabs with a dropdown combobox selection control.
- I've added checkboxes to enable the graticule and spectrum options on the waterfall display.
- I've added a checkbox to enable the AGC code that is now possible with the multimedia
mixer interfaces in the WinPSKX control. The horizontal bar display below this checkbox indicates
the audio level of the AGC action.
- I've added the RigX ActiveX control for controlling my radio
through the CAT interface. This control lets me read and enter the frequency for the radio and select
which VFO to use. I usually set VFO A to 14.070 and VFO B to 14.071 so I can easily jump up to the
higher PSK31 lurking area.
- Note that because I'm using the RigX ActiveX control, I have set the
graticule display frequency to the exact frequency to which the radio is tuned. Because the RigX control
and the WinPSKX control are bound together in this application, as I tune the radio, the current
receive cursor is automatically adjusted to stay on the exact receive frequency. Thusly, I can tune the
radio while monitoring a QSO and the receive frequency is automatically adjusted to track it.
- You may have noticed a new item on the top menu bar, labeled QRZ.
I added this to do a QRZ.com lookup of the callsign that's currently in the "Their Call" textbox.
To add a callsign to the Their Call textbox, you simply double-click on the callsign in the receive
text window. Then when you click on the QRZ menu item, your Web browser is automatically launched
to look up that callsign on QRZ.com. This is a real timesaver at the start of a QSO - you can get
all the info on a new contact with just a couple of mouse clicks.
Carpet Plot Display
This screenshot shows a QSO in progress. Note how clearly the received signal trace stands out in the
3 dimensional carpet view. There is also another QSO in progress, clearly visible, at about 14.072.300.
AGC Action
This screenshot shows the same QSO after K6AA signed over to WØIBV. Note how the AGC action has
automatically boosted the AF gain now that K6AA's very strong signal went away. The AGC feature
means you no longer have to manually tweak the AF gain control on your radio, the WinPSKX control can
take care of adjusting the AF input to the best level without overloading the PSK31 decoder input.
