Re: Rumbling audio,,,,again

Hi All,
How do we know the rumbling sound wasn't actually a signal on the band?
His panadapter is zoomed out so far, I can't squint hard enough to see if the rumble is actually within the receiver passband or not.

Re: New 70000LE MKIII With Protocol 1

Not aware of the ".26" series.
But you did try the ".27A/B/C/E/F/G" series, right? Those are the ones that work FB here on my EP4CE based Orion.

Re: Saturn: A New Apache Labs SDR Transceiver (ANAN-G2)

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?

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 :-)

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?!?

Re: Sequence errors during transmit

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?!?

Re: Sequence errors during transmit

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???
