Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
Yes, it will do that today. All the needs to happen is for a program "p2app" to run; that could be set to start automatically after power up. p2app acts as an interface between the hardware and a client application such as Thetis. It doesn't need a display. It writes some test to a command line, but that's more for debugging that anything else.

That would be a nice addition, so that if you wanted to use the internal display you could, but if you wanted to just use a PC running Thetis you could go that way.

Just in case anyone missed it, Apache is offering two versions, one with, and one without, the front panel and display. Those who think they want to run piHPSDR or perhaps some future version of Thetis/p2app that uses it can get one with the front panel/display. Those who know they will only want to run it with Thetis on a PC can get the one without the front panel/display. And, just to create even more options, both versions sport two HDMI outputs and USB ports, so either version could be equipped with additional displays.
Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
Is there any way to get a few more pictures of the G2 model without front panel?
Would like to see the top, bottom and front of the unit.
Thanks

I would like to know if it will be possible to purchase only the Saturn Board build and tested.

But it does things no other radio can do. As long as it all remains good enough to attract the interest, energy and talent of those that produce those things, and the same from those who enjoy buying (the hardware) and using it, the platform will survive. And when it doesn't it will fade into semi-obscurity like so many other radios before it.

It seems that Apache Labs has developed a Unique Value Proposition—marketing nirvana for many businesses who are vying for competitive advantage. Many businesses try to claim they have a UVP, but those who truly offer that can sometimes dominate the target markets with whom those propositions resonate. {pun intended} It sure looks like Apache Labs has achieved that.

Hopefully 1 week from Today the all New G2 100 watt SDR Radios shall be fully operational for shipment . today is 3 June 2023.
Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
New Proposed shipment date for Saturn G-2 100 is June 26th.

Do you believe that?
I hope I'm wrong, I have $2k down on it but I guarantee the 26th will be the very last delay.

Same here. I will wait until the 26th of June and if there are further delays I will be requesting back my $2000 down payment.

What version of Thetis are we supposed to use with the new G2 radios?

See this topic:
viewtopic.php?f=3&t=4650#p25069
HOWEVER...that patched version of Thetis is not in sync with Richie's recent 2.9.0.8 final release (the one with the voice squelch).
Look for more information to be posted over the next few weeks about how, if and when that might be corrected.
Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
What cables will the new G2-100W come with or what cables will I need?
I just want to be ready when the new radio arrives.

Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
Historically, Apache hardware has only come with a power cable. Therefore, using the photo on the website as a guide, you'll have to supply a cable for everything you want to attach it to.
It would be nice if Apache also supplied a Wi-Fi antenna. Note that this would not be recommended for those running Thetis, for that use the GigE LAN port. If I was getting one I'd make a dedicated connection from the LAN port to my PC, and have the PC and Pi using Wi-Fi for internet access.
The real mystery is what kind of "XLR" connector will actually be on the rear panel, for those that wish to use it.

So far from the picture it looks like a Mini Male XLR 3pin but can not say for sure as the picture is a bit fuzzy.
It would be nice if we can get some basic info on the I/O for the new radios.

Indeed, my condenser microphone needs a bias voltage of 8-12V. Hope that can be provided through the microphone connector.

Hi, since the hardware, and unfortunately not pcb, is open source can you please share the Saturn schematics ?
Thanks, 73

Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
would be nice if they updated the web page with a current pic of front and back and a list of connectors, also some type of startup hint, since this is a new beast, call me dumb but sometimes i cant make heads or tales of the forum.

Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
I would also like to see a pin-out of all of the connectors on the G2-100W so I will know what I need to make up cables.
At this point there should be some basic documentation for these new radios. I understand if a proper manual has not been created but we need some basic info on the connectors. I would like to have everything ready for when the new G2 arrives.

Hi Laurence,
I remember, from your SDRA 2022 presentation, that you were favoring 4096-byte DMA transfers on the PCIe bus for the various streaming channels within Saturn. Did you finally settle on that number, or were there further refinements?

Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)
We never found a need to move from 4096 byte. We can transfer data from all DDCs at full speed with that setting. It's easy enough to change if needed though.
The DMA size is a balance:
small transfers are inefficient because several software driver steps are needed, and below 4096 bytes the transfer time isn't affected by byte count. So there is no point going lower.
Large transfers are more software efficient but incur more latency.
One change that I made - and I think it was already in place by SDRA2022- is to multiplex all DDC streams into a single DMA. This avoids issues of sharing DMA engines and waiting for one to become available. That was a reasonably complex bit of Verilog but it transformed the transfer process.

Oh... that was for DDC transfers. the mic, speaker and TX I/Q transfers can have different sizes. Speaker data seems to be fixed at 256 bytes.
