Gwen, Win4K3Suite does NOT use the same audio libraries as WSJT, it uses native DirectShow. WSJT uses QTAudio. There are some issues with this QTAudio which sometimes prevents proper enumeration of the audio devices. Unfortunately when this happens, driver enumeration gets "stuck" and will not work properly any longer without a reinstall of Windows. Even uninstalling the offending device driver doesn't work. It still remains in the list. This is purely a bug in QTAudio. Been there, done it. I spent hours with the WSJT developers trying to fix this issue on my system and even though we used many development tools to try and find why, ultimately a reinstall of Windows 10 was necessary. I didn't but the next update of Windows 10, Creators edition, fixed the issue. Now if you are using a microphone input on your sound device, are you sure it's working? It would have to be a stereo input for the IQ signals. Here's a quick test: Pull up the spectrum and turn the VFO A knob on the radio. If you see the signals on the waterfall move in different directions around the center frequency, then you are using a mono feed. 73 Tom Va2fsq.com

I have a lovely 3.5mm to 2.5mm cable running from the PX3 IQ output to a spare mike in jack on my PC. I had to do some weird jiggery-pokery with default sound devices to get it to work because Win4K3Suite uses some of the same (or related) code that's also in WSJT-X and other code derived from it, that doesn't play nicely with Windows 7 64-bit. None of those programs will "see" my correct microphone list, though other unrelated programs DO. Those programs only see a pair of old entries that haven't been on my machine in years. I have to trick them to see the devices I want, through setting default devices and using VB-Audio's Voicemeeter virtual mixer program. But when I DO get every tab A in the right slot B, I can set Win4K3Suite to look to that spare mike jack for its spectrum scope source. Works great! I've asked (begged) the authors of the various programs to PLEASE do something about their operation with Windows 7, but I only get shrugs and sometimes rude demands that I simply "upgrade to Windows 10, that works". Seeing the *correct* list of enumerated input device drivers should NOT be something I have to upgrade my operating system to get, when I only get the problem with a very small number of specialized programs. *sigh...* 73, Gwen, NG3P On Sun, Jun 9, 2019 at 9:25 AM Don Wilhelm <[email protected]> wrote: > Rich, > > There is no need to bypass the P3, just connect the SDRPlay to the P3 > IF output. > > The P3 IF output is a replication of the K3S IF output. > > 73, > Don W3FPR > > On 6/9/2019 7:04 AM, Richard Thorne wrote: > > I'd like to try Win4K3Suite with an SDRplay receiver.
