If the MOTU is not connected to the rig what does it have do with the sound channels to the rig? Surely the audio it not going out the USB and back in again.... One setup show above shows audio connection to Virtual Audio and the other looks like it's connected to the MOTU. I've never been able to g...

Couple of questions...

#1 What's the advantage of using one of these? I guess the ASIO drivers might be a bit quicker.
#2 How is it connected to the rig?

It's at 50Hz intervals so I suspect some 50Hz power supply noise -- couldn't be too far away...you'd have to hunt it down with https://electronics.stackexchange.com/questions/214665/where-are-these-50hz-noises-from You can do some inside-the-house hunting with an AM radio. https://www.youtube.com/wa...

You can't compare with voltmeters which are all horribly slow to respond to voltage fluctuations.....

I'm working on a patch to smooth this out...a bit more averaging is needed.

Is there a separate ZZ command for the step attenuator?
Or a command to switch the display?

What dropdown box to set ATT? Can't seem to find such a beast.
I'm trying to figure this one out for modifying FLRig and Hamlib.

Can anybody explain what the ZZPA actually does or if there is some visual indicator in Thetis that reflects it? This is int Thetis 2.9.0.7 MW0LGE ZZPA0; returns ZZPA8; ZZPA1; returns ZZPA1; ZZPA2; returns ZZPA7; ZZPA3; returns ZZPA8; ZZPA4; returns ZZPA9; ZZPA5; returns ZZPA5; ZZPA6; returns ZZPA6;...

My serial# is DX8300219 and it's working here.

I'm running MW0LGE's 2.9.0.7 on my 7000DLE MKII Firmware 2.1.23 and it shows voltage and current readings correctly.

First thing is you can't compare to the 7300 as it's S meter is almost useless. You'll note that the 7300 meter will change based on your RF gain which an S meter is not supposed to do. But most all rigs (non-SDR) do this. You can't compare from one location to another either. Noise levels can be qu...

I used to have problems with audio where I would see fluctuation during transmit due to dropouts or noise -- not sure which.
But...since Windows 11 updated with a new audiodg.exe file I this problem has gone away.

What it sounds like is the difference between Core usage and Logical Processors usage. I've got a 16-core 32-processor system Ryzen 9 5950X and Thetis runs at 2.5% on both Windows Task Manager and ProcessHacker. There are some settings that can affect this.... https://www.nextofwindows.com/windows-1...

The FFT data would be something like 30*1024*2 bytes/sec or around 61,440 bytes/sec. Easily done over a loopback UDP socket.

Waterfall would be the same.

Happens on all bands.

And what makes you say it's VAC instability?
Not sure that would explain why resetting audio in Thetis fixes it (other than recreating the audio device to VAC).
VBAudio is used by audio professionals with multiple tracks without any such problems.

I am convinced this is a bug in Thetis. I have the same problem. Toggling the Power button fixes it. 7000DLE MKII here with 2.1.23 firmware Protocol 2 v3.9. I put my rig on a fiber optic adapter but my next step is a dedicated fiber optic link for the rig to see if it makes any difference. One of th...

Sure would like to know more about that power supply.

And what's the problem with that? Nobody is going to rewrite it....not sure why anyone would want to.

Latest Thetis is about 5 months old.

Cheap router in the modem. It depends on two factors. Router throughput and whether or not each port is independent (i.e. where on can route from one port to another). If all you have plugged in is your computer and the rig then the throughput is the problem. If you have another device plugged in (l...

Maybe you should reflash the firmware There is a phenomena of high energy particles in the atmosphere corrupting memory chips and I believe also flash memory which may explain why some firmware gets corrupted.

192.169.1.X is not a private network address. Did you mistype that?

What you want to do is this

Change your 2nd ethernet card to:

IP address 10.0.0.1

And put the rig on 10.0.0.2
You can use netmask 255.0.0.0

That is a violation of the electrical code. I imagine your computer is plugged into a wall socket and grounded through that, right? So you now have a ground path from your rod outside through your shack and back out the other ground since your computer is also grounded to the rig through the etherne...

Is your central station ground hook to the house main ground rod?

Heavy ground strap to what? Please describe your complete ground system.
A non-resonant antenna will have a lot of common mode going on the shield.

Have you turned off power saving on the ethernet card and also any "green" settings in the advanced settings?

And what kind of antenna do you have?
And what does your shack grounding system look like?

So you're doing CW and/or Voice?

What other software are you using?
