  • It's a good thing I am not self-conscious about displaying my Linux ignorance in a public forum like this. After my last post I tried to ssh using 'root' as the user, and serial # as the password, and voila I was logged in with a complete view of d…
  • Yes, adding a secondary router is an obvious option to get around the AT&T nonsense, I was just trying to have one less device to configure. And one less switching power supply, sitting near the Kiwis. I have many years of experience setting u…
  • You are correct, I just realized it is still running version 1.538. I turned off the auto updates for the time being since it is running well and I do not have physical access to it.
  • I am happy to say that the system appears to have "cured" itself overnight. I decided to leave it alone, despite the temptation to cycle the power. it also came back on the KiwiSDR map, running version 1.543. Hurrah!
  • After letting one of my Kiwis update from version 1.538 to 1.543 I am getting either the attached error message or "refused to connect" browser errors. Clearing the browser cache did not seem to help any. The admin page sometimes loads b…
  • Hardly a day goes by where I don't marvel at the KiwiSDR, and all of these continuing software updates only increase my appreciation of the "value proposition". One thing I've always been curious about is the time required for an update to…
  • Just realized we're now at v1.535 - this is a dizzying pace of updates, and impresses me to see so much ongoing development work....often for extra features I wasn't even aware of, like DSC.
  • Martin, I was composing my last reply at the same time you posted those details about broadcast station bandwidth. Thank you, that is EXACTLY what I was looking for! All makes good sense. 73, Bruce
  • The AM broadcast spectrum is not terribly cluttered, with just one other strong local at about -30 dBm. At present I am using about 8 dB attenuation to suppress OV indicator flashes - although I suppose the time constant in that would overlook ins…
  • I really appreciate the detailed and thoughtful replies to my original query. Setting up a second Kiwi at a new location (EM83 grid) prompted me to explore this question around switching power supplies. The one I am currently using only causes &qu…
  • I was successful with a point-to-point ethernet connection with my Win10 laptop. Nothing fancy at all, but for someone like me with limited knowledge about networking it was quite pleasing to get this to work. I am posting explicit instructions he…
  • OK, I apologize for that post, the answer was ALREADY there on the operating instructions page...what follows is a copy/paste for future reference...I will give it a try even though it states that it does not seem to work with Windows 10... "Po…
  • Thanks, Si diode as a voltage dropper sounds like a good approach. In the past I have used 5V rechargeable USB phone chargers, but was never fully convinced they were as clean as regular batteries since they have a power switch/charging circuit bui…
  • Thanks for the replies and your patience with my never ending curiosity! I probably should have been more explicit in my original post. What I was trying to ask is... why are the three SNR columns at the http://rx.linkfanel.net/snr.html site not f…
  • Thanks for the tip on CATsync, that looks like it could be exactly what I am looking for. What I still can't quite grasp is the I/Q pipe between the KiwiSDR and something like SDR#. Is it essentially just an audio feed, i.e. so the waterfall in SD…
  • OK, I was able to get the case assembled. I assume the best orientation during use would be with the Kiwi board on top, for the best heat dissipation. I wasn't able to get the rivets fully pushed in without mangling the thin inner shafts, so I'll …
  • Fantastic! The printed copy that came with mine (v1.2) was not quite as detailed as that. Now I know exactly what I was doing wrong, thanks!
  • For my other SDRs I use SDR# for control and access, and for SSB signals it sure is nice to be able to use the scroll wheel on the mouse to skip up and down in 1 kHz increments. Or 10 kHz when flipping through the AM broadcast band. I'm still so ne…
  • Can't resist adding one more comment to this thread, I am DELIGHTED with my first KiwiSDR....but it took me several YEARS to finally order one, because it is described as a "kit". That is a daunting word to non-kit-builders like myself. …
  • The OnlineComponents web site says they currently have 49 on order, to be shipped next month. And at a great price (that's where I got mine from last month) The catch is, you have to enter their specific part number (110060490) in the search box t…
  • I am definitely beginning to appreciate how misleading the SNR values can be without viewing the spectrum detail. Based on viewing a variety of publicly shared Kiwi's it looks like quite a few of the higher values are situations where the spectrum …
  • Yes, I agree only the S-meter/dBm is usable for true values. The odd formatting on my post with all the numbers made it a bit ambiguous. For each line the first value is the power output from the TinySA, the second value is what the S-meter/dBm di…
  • Glenn, As always, thank you for your patience in explaining the facts about noise levels. For my own curiosity I made some signal level measurements with the KiwiSDR, using a TinySA spectrum analyzer as the source. The TinySA is not a precision so…
  • rrobinet, Thank you for the bandwidth values, exactly what I was curious to know about. So I definitely MUST have the Pi co-located on the LAN. Right now the only Pi I have is in another state, running OpenwebRX with a couple of SDRs. Just for fu…
  • Much appreciate the useful and detailed responses to my original post, and I've added the groups.io for wsprdaemon to my ever expanding list of forums. The only piece of missing information I am still seeking revolves around the network bandwidth us…
  • I did some additional comparisons for WSPR decoding yesterday with the same antenna and audio piped into separate instances of WSJT-x via virtual audio cables. The spot count was consistently higher for the Airspy HF+. Looking at the signal report…
  • JKS, Thank you for the detailed response to my query. I'm still finding my way with this SDR, and yes indeed the 30 MHz bandwidth really shines compared to other SDRs. I am almost relieved to hear that the Airspy HF may be more sensitive than the …
  • Thanks for the rapid replies, I am new to the kiwiSDR so I did not realize the built in decoding for WSPR is not recommended for general use. From what I have read so far it sounds like the wsprdaemon is a separate program running on another Linux …
