kiwirecorder resampler does not work as it should due to an issue with the related python libarary AFAIK. I pipe through sox to get what I want.

https://forum.kiwisdr.com/uploads/782/W2252BH65BF8.png jimlill.com:8073 and jimlill.com:8075 are 2 of the 4 kiwisdr there. The other 2 are dedicated to wspr. I am currently suffering from some local noise that I haven't had time to chase.

both sox and soxi are useful tools for working on this kind of thing. Although sox started life as a Linux tool, there are MS and Mac versions of it. https://sourceforge.net/projects/sox/files/sox/14.4.2/

The addition of MMSSTV would be great but we have come to rely on John to do the majority of the heavy lifting on both Kiwi hardware and software. It would seem like extensions is an area where you smart programmers might be able to contribute. It i…

per Christoph as of today "The python libsamplerate module is broken"

I tried the -r earlier this year and founf that python didn't do it right. I ended up piping through sox . Has the Python thing been verified to be fixed?

are your neighbors ameniable to adding something to their radiating systems?

DIN barrels are available with "green" terminals too!
-
The DIN barrel connector is pretty popular across a number of devices. John, have you found issues? The only thing I have is that if you pick a PSU with USB, it's 5V a DIN barrel might be anything

how about falling back to last IP assignment rather than the default which might catch a lot of the occasional issues

congrats and <applause>

How does any SNR test differentiate a "real" signal from a spurious carrier?

In the last few days, a Solar energetic particle (SEP) event seems to have more impact on HF than the X-Ray flares. The X-rays get here in about 8 minutes 20 secs, The fastest particles may acheive 80% of that speed. X-Ray events are rather transien…

all the raw data for "years" is available on that site if you would like to see how it aligns. It takes some digging! this is one of the places https://services.swpc.noaa.gov/json/goes/primary/xray-flares-latest.json

see this for your AM demod https://github.com/ha7ilm/csdr

there's been both elevated X-Ray flare and Proton Flux levels. The latter hasn't been occurring as often as the X-flares. Both are bad!

I have done a lot with kiwirecorder and I/Q wav files so I know that works. I have just not used your exact cli string I used ./kiwirecorder.py -k 5 -s $1 -p 8073 -f $2 -m iq -L 300 -H 3600 --ncomp --tlimit=$3 with $1 $2 $3 added on cli

You can explore this site but I'll bet there'll be nothing with records to this https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm

I'd like to offer DRM and 20.25 on one of my public kiwis so if users want "narrow DRM" there it could then work
-
My use of sox was to take wav files recorded by kiwirecorder and resample them accurately to the desired/required sample rate. It worked like a charm.
-
you'll also need libsoxr-dev

from my experience, sox with the proper lib does fractional resampley and is often the only thing that works in some of these situations.

my 8073 box is back in 3-ch mode

lsusb is an ls of usb devices like ls is normally of files yes, it does create a usb device

I can confirmn that an Ontrak ADU218 appears in lsusb

can you ping it? or ssh to it?
