Re: VAC under/overflows due to changes in how Windows handles Timer resolution

In the FWIW department: I've been playing with this for two days now, just to see what's what. I don't think the reports in powercfg have a lot of meaning, but that's just a gut feel. I get the same reports as everyone else. One thing I did notice is that I was having some very slight ticks/pops on ...

Re: VAC under/overflows due to changes in how Windows handles Timer resolution

Many times a Windows update will damage audio drivers. I've lost count of the number of times I've had to reinstall Voicemeeter. If you are rolling back without any improvement you might consider an uninstall/reboot/reinstall/reboot cycle for any relevant audio drivers.

Re: Transmitter composite noise

Mark, Nobody has a hardware architecture that will support it, with the possible exception of Flex and perhaps such niche products as SunSDR. Remember that you need a transceiver that provides full duplex transmit and receive, a path to that receiver when transmitting, and well controlled and unders...

Re: Transmitter composite noise

Mark, I can find no problem with your assessment. And there's no reason to single out those rigs. The best performing rig was listed at -40dBc. Based on the spectrum analyzer plots shown in the paper it would appear that this is measured in a 100Hz bandwidth, so -50dBc/Hz. This is, of course, quite ...

Re: Transmitter composite noise

Bragging rights for sure, and a technological tour de force, but what does this really mean? Consider more typical conditions of an S9+20 CW signal, which is the largest one typically sees, not that there aren't larger signals out there, but say as a 90th percentile type of situation. That's -53dBm....

Re: VAC under/overflows due to changes in how Windows handles Timer resolution

I also add that, using ASIO, my VAC PortAudio settings are both 0, and the RingBuffers are set to 5 and 8 respectively. No problems at all, unless I see a CPU spike from another application or service.

Whether you agree with my assessments or not, my audio has remained stable under 20H2.

This is also a no brainer, at least once you realize that your "radio" is the combination of both your PC and the hardware that you buy from Apache, and that all CAT connections come from the PC, not the Apache hardware. Indeed, most of the "radio" is in the software, not the har...

This only works with certain ASIO drivers.

It does not appear to work with VB Audio (Voicemeeter, VB Cable) or Presonus drivers.

A thousand times no on anything that is not Bootloader where P2 is concerned.

You need to install winpcap (Google it) for Bootloader to work correctly. That's what is missing.

Re: anon 7000 DLE MKII PowerSdr MRX PS

That's correct. You have P2 firmware. So PowerSDR will not work with it.

If Thetis is working well then there is absolutely no reason to bother experimenting with PowerSDR. Thetis is by far the more advanced client.

I would not make that assumption.

I tried looking through the code but it's so convoluted I couldn't follow it. I did see code that implies setting the ATT control is the same across all hardware types. But I'm not at all sure about reading that setting.

Do you have Protocol 1 or Protocol 2 firmware loaded into your 7000? Thetis will work with either. PowerSDR will only work with Protocol 1 firmware.
