Looks like the 7000DLE was taken down from the Apache Labs website over the past weekend.
Too bad, it was a good rig

FYI another option:
Lynx Studio makes a nice line of PCIe audio interfaces that DMA your audio samples directly to/from the computer's data bus.

Something to ponder:
Is the Saturn being manufactured under openHPSDR licensing?
Or is this now a totally new platform and considered completely proprietary to Apache Labs?

Surely, you know this.
But you did have RX2 running when you were attempting to use VAC2?

Good question.
So I restate it here.

I can personally recommend this one made by a couple of retired Tektronix engineers. It's sort of expensive but built like it came from Tektronix. And for an extra $75 it will come with its own NIST certificate

What about the poor guys that ordered a 500W 8000DLE MKII way back in August 2022?
Surely, they are not being asked to now go to the back of the queue.

I am suspicious of these new Intel performance cores and efficiency cores. Is there going to be some Windows API that allows applications to specify that certain threads get first dibs on a performance core at thread creation time? Otherwise, our quasi-realtime streaming threads in ChannelMaster may...

My Bodnar drives my Presonus Studio 192 Mobile with no issues.
I think you'll be fine.

For those using the Leo Bodnar GPSDO are you running a 10 MHz bandpass filter to mitigate possible harmonics from the square wave, and If so what make and model of BPF? Not using a BFP with my Bodnar GPSDO here. I'm using the dual output Bodnar with 10Mhz driving the Anan 7000 ref input and 48kHz d...

Are the PreSonus Quantum Series interface units the only ones now left from them that still offer Wordclock reference input?

Hi Walter,

Do you happen to know why the output is only 0.5W? If you look at the schematic, it appears that the output of the 2W driver stage is routed to the SMA socket (when operating in XVTR mode). I've never understood this?!?

I sent you a PM, but you didn't open it.
Would you rather I email instead?

Thetis code has been described as a nasty, tangled bowl of spaghetti. I think that is a fair statement as long as you're talking about the Thetis project per se. The WDSP and ChannelMaster projects, on the other hand, are well structured and well documented IMHO. The learning curve is steep, but en...

I remember from TeamSpeak sessions, that Warren NR0V was working on this within the context of ChannelMaster support for the DFC (Direct Fourier Conversion) based Minerva board. The trouble he was having was related to thread scheduling of the CUDA cores, in support of the multi-threaded requirement...

Another P1 related disaster
Why on earth couldn't we have left it behind when we had the chance?

Is it possible to post screenshots and/or images directly into Private Messages?
TIA, Bryan

I have an ancient, outstanding issue where CM (as opposed to wdsp) hangs on to a handful of threads between every Start() invocation. My comment about AVmm was mostly for ChannelMaster.dll, in particular the audio threads. In my view the audio is #1 priority (literally), behind even the UI responsi...

I use the new AVmm thread priorities if I can, but fall back to less poky threads if these are not available. Hi Steve, Just FYI: Back when we enabled MMCSS in Thetis (version 2.6.9 I believe), Warren NR0V and I carefully chose only the most time-critical DDC, DUC, and audio threads in WDSP & C...

Oh yeah. That's what I meant by "rewind" type sequence errors. I'll post a screen shot of one the next chance I get.

w-u-2-o wrote:That seems like an oblique way of saying that 7000's will no longer be produced.

Sure does!

Right, but what I'm thinking of is the type of sequence error where the sequential numbers jump back (say by 100) and then start over again from that point, counting forward and repeating the sequence of numbers it just ran through. It's hard to imagine how the network stack could do that?!?

Once the new Saturn SDR boards become available and get into common use, I guess we'll finally prove whether or not it was FPGA issues causing all the sequence errors.

The "rewind" style sequence errors seem very hard to blame on the stack. How would such a thing even happen???

Can we interpret Abhi's phrase "alternate supplier" as meaning Xilinx and therefore assume the new 8000s will be running Saturn SDR boards instead of Orion?

Laurence's YouTube video is a bit unfocused, so it's a little hard to see the block diagram. But it's my impression, from looking at the bullet points, that the DDC is no longer using CIC decimation filters? So it's doing all the decimation in FIR? If so, that's pretty cool!

Well, if it gets all the Ethernet stuff out of the FPGA for good, it was probably worth it for that alone
Still though, a Pi seems like gross overkill. Monday Morning Quarterback said that

Doesn't this just turn it into a Flex?
Albeit a Flex that can, also, run Thetis.

Hi Rick,

I have an EP4CE equipped 7000 (also a spectrum analyzer) and would be happy to participate.

Did you try shutting down VS and just launching Thetis directly from the Release folder using FileManager or Run??
Sometimes VS seems to mangle the database.xml file. Try deleting it and starting from scratch.

What about PureSignal?
Does Pavel's image do the DAC copy business that PS depends on?
