  • Got a reply from András. Should be fixed now.
  • Jack, I increased the post edit time from one hour to one day.
  • Notwithstanding the above, should there be a "Kiwi v2"? Maybe. I think most would say no effort should be put into that until most of the current software bugs & enhancements are addressed. Your idea about offering the current hardware with an u…
  • Hopefully sdr.hu will be fixed soon.
  • I didn't mention it on the forum, but the FAX skew/slant problem was fixed in the v1.100 release (https://github.com/jks-prv/Beagle_SDR_GPS/commit/ba3ec102465bfe29d8a6582cb4068ba4c8dbe700) It was just a software bug. The audio sample rate not being …
  • The icon fix was database caching related. So perhaps the receiver entry listing caching itself is now broken. The operation of sdr.hu won't effect the access of your Kiwi at its public URL. And the up-to-date status can be found at the alternate li…
  • I've had another report about this and will ask the people who maintain sdr.hu to check. Yesterday they fixed a database update problem that was keeping the kiwi bird icon from appearing on the listings. So perhaps this is related. sdr.hu moved rece…
  • Seems okay here. After a restart I have 350 fixes in 30 mins, a TTFF (time-to-first-fix) of 50 seconds and 6-7 sats tracking, which is actually better than average for my setup. I'm working on a scheme so the update saves the last few binary version…
  • Martin's explanation is exactly right. I need to remove the delay before the "last saved" frequency is applied so you don't hear the audio glitch. You'll note the waterfall zoom has a similar problem.
  • The waterfall used to scroll more smoothly. But then people were complaining about the lack of synchronization between the waterfall and audio streams. A fix was added for that problem but the result is that the waterfall is sometimes jerky as it at…
  • Okay, in v1.108 there is now an option to reboot the Beagle, rather than simply restart the server, after an update. See the update tab on the admin page.
  • I originally replied to this thread a bit in advance of the update going out. But now most Kiwis seem to have updated to v1.107
  • The Kiwi software does not support USB WiFi dongles. The Beagle Debian software for these is poor/buggy and I don't want the support burden. Best to use an Ethernet-to-WiFi adapter. A couple of successful installations are reported here:http://valen…
  • v1.107 will let you reduce it to 4 Hz. At this low of a value the filter skirts aren't so great as a percentage of the passband width. But there is a definite signal-to-noise improvement over the previous 50 Hz minimum, so this was a worthwhile chan…
  • The problem is it took almost a week of work to integrate the registration software from noip.com into the Kiwi server. I don't really want to spend that amount of time for another service. Some people have been waiting more than a year for me to im…
    in DDNS from KiwiSDR Comment by jks July 12
  • This feature is on the wish list.It is possible.
  • I have gigantic VFD problems from the elevators/lifts in this apartment building, so your information about the bead is very valuable to me. I had assumed the EMI was radiated directly to my E-probe antenna. But perhaps it is really conducted on the…
  • Yeah, this is a problem with how your network router works. Unless your router supports something called "hair pinning" (NAT loopback), and most of them don't, then you can't use the public URL on sdr.hu on your local network where the Kiwi resides.…
  • What's the error message? Is it from the "sdr.hu registration status" field on the sdr.hu tab of the admin page? Or the "status" field of the DUC section on the network tab? Since you're using DUC on no-ip.com, on the sdr.hu tab selection menu at bo…
  • Excellent J-Luc. Yes, it takes real work sometimes to achieve decent shortwave reception in the modern world. We have a few more suggestions on the website: Noise reduction advice It is very worthwhile experimenting with grounding configurations. An…
  • You have to look using the right conditions to decide if the +0.05 value is resulting in correct operation or not. The difference on the IQ display between +0.05, -0.02 and no offset at all will be washed out unless the noise level is less than S3 o…
  • Yeah, okay, this has something to do with the main FIR filter. You can see this if you haven't already corrected the offset. If you bring up the IQ display, select USB or LSB, then as soon as you slide the lower edge of the passband over the carrier…
  • v1.104 brings back the "IQ balance" button on the IQ display extension. But this time with a confirmation dialog. But there is something else strange going on here. Some time ago I noticed that the default IQ offset (really DC offset) values needed …
  • Okay. Well, if you mail me the dead Kiwi board I'll send you a new one for free. I can justify that by getting a chance to analyze the failure and hopefully make future designs better. Please email me: support@kiwisdr.com
  • Are you using a power supply that has previously been known to work with a Kiwi? The case of "it works with the BBG alone, but not with the Kiwi added" is a well-known symptom of a power supply that can't handle the current requirement, or a cable f…
  • Yes, the v1.100 release improved the situation. Details here: https://github.com/jks-prv/Beagle_SDR_GPS/commit/ba3ec102465bfe29d8a6582cb4068ba4c8dbe700

  • Yeah, I should have spent the time to add a low Rds(on) P-FET.I should have spent the time to do a lot of things, but then we'd still be waiting for the Kickstarter, lol.. Best YT video about this topic is here:   And the most humorous is here:
  • It's possible the Kiwi board is fine. It depends on how the PMIC on the BBG failed exactly. 5V power from the Kiwi board DC jack goes to the BBG first, through the power management IC (TPS65217C PMIC) then elsewhere on the BBG and back to the Kiwi b…
  • Yeah, I'm having trouble getting bash to behave properly as a "login" shell (e.g. reading /etc/bash.bashrc) and other things. Already I had to manually set $TERM and $HOME and do some things to prevent the ls and grep commands from sending colorized…

  • Sometimes the web socket interface delivers strange data. An unknown single binary byte in this case. I've added some code to print the values of these so perhaps the underlying cause might be understood.
