I don't know, but I can tell you that on one of my projects we just ordered production quantities of Xilinx Kintex Ultrascale FPGAs and deliveries are running 52 weeks out

I'd buy one in a second if it had remote control over the network. I asked him if it was planned for the future. Unfortunately it is not.

Hi Scott DDUtil last version is for use with Flex Radios and the last versions only work with the signature series (6xxx). To enjoy DDUtil with Flex legacy or Anan radios with Power SDR or Thetis you must install a version prior to version 3.2.5.xx. (DDUtil_V3) This drive control may be set by band...

How important is it to have a directional coupler like the Xtronic unit? Theoretically a directional coupler will provide better results because there is no reverse power component carried back to the PureSignal receiver. However, I don't know if anyone has ever determined whether or not the differ...

The DDUtil "autodrive" feature can be very handy for this sort of thing. You may wish to take a look at that. If you are not familiar, DDUtil is a "helper" program that has all kinds of useful talents. See here: viewtopic.php?f=16&t=3040

DDUtil will not be able to do this for you. You could write a script in something like Python or Java that automates this, sending the correct sequence of CAT commands and recording the results. However, you are in luck, because a tool already exists that can do this: SWR Plotter . You will need com...

If it's the PWM "rattle" that's bothering you, simply rewire the fan directly to 12V. If it's the fan itself you might do a little better with a slightly quieter fan. Others will have to suggest what make/model to get, I can't guide you there. If that's still not good enough then you will ...

The hardware will come with P1 firmware preinstalled. That will work with either PowerSDR or Thetis.

If and when you want to change the firmware, read the sticky posts at the top of the firmware sub-forum.

Eagerly awaiting your results, René!

Thanks for the kind words, Ruben

Unfortunately I'm totally out of ideas at this point.

Short answer - maximum PS feedback level is set by the no damage max. input level to the hardware, which is +13dBm. - minimum PS feedback levels needs to stay above -10dBm, below that PS performance will suffer. However higher input levels will provide better SNR vs. internal crosstalk; this is more...

KX4M wrote:One possible solution that I use in other applications is the Direct Monitor feature on Focusrite’s Scarlet series of audio interfaces. This will allow you to monitor yourself in low latency via the headphone out on the device.

That's my (b) solution, above.

Unless you are one of those humans who is immune to listening to an echo of themselves, it is effectively impossible to do what you want because of the latencies (delays) inherent in the openHPSDR software architecture. If you eliminate all audio processing in Thetis/PowerSDR: limiter, pre and post ...

It's a mystery, Dennis. But you should upgrade to Thetis 2.8.11.

You need a UMC202HD interface, or equivalent.

Mark, You can reduce your latency by quite a bit and probably get a better sounding solution by using better tools. You've got a good, ASIO capable interface, so the foundation is there! Use Voicemeeter Potato to tie everything together so that you can use ASIO. Play with Voicemeeter and the Behring...

It is extraordinarily hard for me to believe that any Windows sound interface would generate 90 or 200ms of delay. That is what would be required to fit the evidence. There must be something else wrong somewhere. What happens if you use the motherboard sound interface instead of the Soundblaster car...

You can obtain CAT control of an SPE amp either directly from PowerSDR/Thetis or via DDUtil (make sure you use an older version that still supports legacy software--newer versions only support SmartSDR) as long as you have your serial cable built properly.

Does the problem occur if you are running into a dummy load at normal RF output power levels?

The output of the sound card is fed into an integrated stereo amplifier. We I turned the volume on the amp down the sound disappeared completely. Turned it up and it's there. Wit the sound off on the stereo amp, I increased the sound output via RX1 on the Thetis UI. The noise is completely gone. Th...

One thing I noticed. If I disconnect the microphone or reduce the microphone level (Audio-Technica) the burst of noise disappears. So the noise is getting in through the microphone before the receive is muted on transmit. This is exactly as I posted above. But I'm still thinking there is an overt f...

Yowza! So many things to fix... First, if you are using PureSignal with the internal coupler you can't have RX Bypass on TX selected if you want PureSignal to work properly. With this selected, RX1 is connected to the Bypass connector on the rear panel during TX. Second, you need to match your sampl...

While waiting for more screen shots, my guess is that Ruben has a large buffer somewhere in his audio chain, so large that it is in the milliseconds range. Thus the audio in it is delayed substantially compared to the PTT signal.

OK...so this is related to VAC use. I have used a wide variety of VAC configurations, some quite complex, and have never observed this problem. It is unlikely to be associated with the delay settings. I use 0, 0, 2 and 0, so even less delay than most. No problem. I am more suspicious of people's Voi...

Elevated noise floors like this are a common symptom of firmware not working on your hardware. More specifically, in the vernacular of firmware engineering, "it does not make timing", or "does not achieve timing closure". Probably more than you want to know here . Unfortunately, ...

You need to tell us more about how the audio gets from your microphone into the radio. Straight shot mic into the ANAN, or something else?

It is no longer necessary to report these.

Simply put "8000 SPE" into the search box in the upper right corner of the page here and you will find what you need.
