  • If you're talking about PACTOR, we had this discussion already: http://forum.kiwisdr.com/index.php?p=/discussion/2375/pactor-1-4
  • Okay, I found the dumphfdl bug. Now to fix properly and move forward..

  • Thanks. I couldn't get this file to work with dumphfdl either. So there is some kind of issue with zero-IF files. I tried the usual suspects (big/little endian reversal, I/Q swap) with no change. When you did this the Kiwi dial frequency was 6721 wi…

  • Does anyone have a Kiwi IQ file recording that is known to decode with any of the HFDL decoders? After some trouble I was able to get dumphfdl to build on Mac and Kiwi Debian. And it will decode an HFDL signal from a wide-band IF IQ file (from an SD…

  • When I added the 6 and 13 MHz ISM bands last March (for the UK balloon-mobile crowd) I was told the dial frequencies needed were 6780.75 and 13553.75 (the ISM bands have entries at the end of the WSPR extension "band" menu along with IWBP …
  • The counter argument is that something as complex as DRM actually works with its fancy COFDM modulation and an MPEG xHE-AAC audio codec thrown in as well. Like DRM (and ALE) it's just one of those things that you have to try -- and see if you can ge…

  • Nils (DK8OK) paper is an interesting read: http://www.udxf.nl/HFDL-some-ideas.pdf

  • I'd have to analyze the waveform demodulation code and try and gauge how intensive it is in terms of Beagle compute resources. The next problem is that you guys won't be happy just seeing screens full of ACARS messages. You'll want some sort of mapp…

  • You pushed the "IQ bal" button on the IQ extension and then did not carefully read the warning in the popup panel, didn't you? There's nothing wrong with your Kiwi that correct IQ balance wouldn't fix. http://forum.kiwisdr.com/uploads/221/…
  • It's being worked on apparently: https://github.com/nodesource/distributions/issues/1266
  • More info: http://forum.kiwisdr.com/discussion/497/update-on-the-2-meter-band-interference-issue
  • A thread about using a small, external USB-to-Enet bridge is here: http://forum.kiwisdr.com/discussion/comment/6047/#Comment_6047
  • Okay, apologies for the trouble.
  • That's actually a very good idea. I'll look into it.
  • Probably because you need to stop the server before editing the file. Otherwise the server will overwrite your change the next time it needs to save something to admin.json Do something like: cdp; mst cdk; sed ... cdp; msa After a restart it will st…
  • I thought I had switched the factory to using v1.3 of that doc. Apparently not..
  • Common problem. Look carefully at page 9 of the printed QuickStart guide that was packed with the kit (also here: http://kiwisdr.com/quickstart/quickstart.pdf) Important: Metal side pieces go on top of bottom plastic plate. Doing so will give you en…
  • Fixed in the next release. Moral: don't operate heavy machinery (or program) while sleep deprived.. Update: I can now modify/add/delete a 10k entry dx list (1M byte size) with just a brief waterfall pause and no audio drops.
  • The old single "Enable GPS?" yes/no switch was replaced with the three "Acquire Navstar/QZSS/Galileo" checkboxes. "enable_gps" remains in the configuration, but has no UI tied to it. However it's a bug that the current …
  • I'm going to close this thread because it's not going anywhere helpful. If you want to bash me or my project that's fine. But please take to some other forum that I'm not paying for. Meanwhile, more insight into the origins and goals of the project …
  • See the first post of the recent topic "ALE 2G scan list suggestions": http://forum.kiwisdr.com/index.php?p=/discussion/2369/ale-2g-scan-list-suggestions
  • Okay, it's pretty clear you have a damaged software installation. There could be many reasons for this. I'm surprised it runs at all with those symptoms, which I've never seen before. Here's how to set aside the current build files (in case the unde…
  • Maybe if B-H is supposed to have these drawbacks, the existing Hanning & Hamming parameters could be further tweaked ? Window functions like Hanning & Hamming have fixed definitions with no adjustable parameters. Although there are plenty of…
  • @GBI Next to the frequency display is a Select Band list. The amateur bands do not include 30m, 40m, 80m, and 160m.  Something fundamental is wrong here. Below is a screenshot of the open "select band" menu. You have to scroll down to the…
  • Well, that's pretty interesting. Looks like the Blackman-Harris window function should be the new default. I never considered it because the Wikipedia article on spectral leakage suggests B-H has the property of raising the noise floor slightly in e…
  • - I would like to see a prominent frequency and mode display.  Yes, that is not a bad idea. Just as we desperately need a purpose-built mobile interface we could probably use some changes appropriate for larger desktop screens. The UI was designed u…
  • v1.468 October 2, 2021   ALE 2G extension: added "lsb" URL argument that applies to URL scan list (if any).   FSK extension: Get update of shift position crosshairs working again.
  • v1.468 October 2, 2021   ALE 2G extension: added "lsb" URL argument that applies to URL scan list (if any).   FSK extension: Get update of shift position crosshairs working again.
  • There is no LSB option currently when defining a user scan list in the URL. But I will add this for the next release.
