Re: problems with mrx not starting

Hi All,

If you recently updated your Windows 10 from a very old build of Windows 10, you may have to install Microsoft Visual C++ 2015-2019 Redistributable (x86) version 14.2 to get your PowerSDR/Thetis running again.

Re: Visual studio / software questions & input

Hi Joe (WD5Y),

There should be a property in the console class that exposes the checkbox state in the property’s set accessor. Just call the relevant property from your code in the wideband class.

Re: Presonus Studio 192 Mobile

Paul,

Interesting experiment: Without changing any of your settings from above, remove the 48kHz word clock going to the Presonus and see what that does to your hourly overflow underflow count.

Re: Presonus Studio 192 Mobile

Not if you have already tried force = 1 on the resampler controls.
I assume you did, so that’s about it.

Re: Presonus Studio 192 Mobile

Hi Paul, Since your radio and sound device are now both referenced to the same GPSDO, there’s no longer any danger of the VAC1 ringbuffers overflowing/underflowing due to clock domain mismatch. So you should try forcing the variable resamplers to 1, which stops the matching loop from constantly twea...

Re: Presonus Studio 192 Mobile

Paul, PortAudio may be requesting a larger ASIO block size because you have your latency settings configured for automatic. Try checking all four Manual checkboxes and setting all four spinners to zero. See if that allows ASIO to operate at smaller block sizes when VAC1 buffer size is set accordingl...

Re: Presonus Studio 192 Mobile

Paul, That’s too bad about the Studio 192 block size not following changes in VAC1 buffer size. PortAudio tries to take care of that for you, but it’s up to the Presonus ASIO driver to comply (or not). It’s important to make sure the VAC1 buffer size and the ASIO block size are in agreement, otherwi...

Hi Paul, It’s perfectly normal for the Var Ratio to “hunt” around a bit when referencing your radio and sound device from a common clock. Mine sure does. Even if you check the Force box, which stops the matching loop from steering the variable resampler, the matching loop is still trying to measure ...

Re: Resampler Adjustment

Hi Brent,

When you say buffer latency must be in auto, do you mean the ringbuffer control or the PortAudio control?

What F/W sampling rate are you using?

What sound API are you using, ASIO?

Re: Presonus Studio 192 Mobile

Hi Paul,

I believe the spec for Wordclock is just a TTL square wave at whichever sample rate you’re running (48k, 96k, etc).

Re: Presonus Studio 192 Mobile

Paul,

Arguably the best feature of the Studio 192 is the Wordclock reference input. Clock your radio and the Presonus from a common GPSDO and then you no longer need a variable resampler.

It may help if you post a screenshot of your VAC1 setup form (or VAC2 if that’s what you’re using) for folks here to look at and analyze.
