All KiwiSDR connection attempts appear legit in the recent user.log. Hopefully it stays that way. Ron - KA7U

Not good enough to demodulate, but neat to get it this good. Ron - KA7U http://forum.kiwisdr.com/uploads/578/KA02OTP3ENUL.png

@ChrisSmolinski I think for a user, the most current SNR would be helpful in choosing a receiver for a particular region, especially if it showed up in the "mouse hover info window" on the http://rx.linkfanel.net/ map. The immediate value …

This website will load the URL and display it in an easy to read format. https://jsonbeautifier.org/ . It looks like the time zone is the KiwiSDR local time zone? If that is the case, then the user of this data will need to consider the time differ…

A blank DRM carrier from: 3205 KHz, KCBS, Pyongyang DRM (Digital), DPRK (North Korea). Receiver location Grid Square DN14lf near Weiser, Idaho, receiver KiwiSDR, Antenna 210' top dipole, Date March, 20, 2021. http://forum.kiwisdr.com/uploads/148/GG…

Was watching a new signal on 29.4 and it suddenly went off. I selected the 160 button to help clarify the signal in the display, that changed the mode to AM. So not sure what goes on with those buttons to the right of clear. Actually not certain abo…

The search box in the blue title bar will find lots on the topic. Try wifi kiwisdr in that search. This post might be quite useful to you: http://forum.kiwisdr.com/index.php?p=/discussion/comment/9270#Comment_9270 Wifi isn't supported, but with dete…

Glenn, I checked on it and it is faint but visible on the waterfall here at ka7u. A serious broadband noise consisting of spurs showed up about 5 minutes ago and I have no idea where that came from either. First time I've seen it here. We are having…

The white bar in the S-meter is a very nice addition to keep track of the AGC setting. I really like that as it is a great reminder of where the AGC is set. It doesn't zero out when AGC is off and Manual is being used. Not a big deal, but worth the …

http://carbonstone.blogspot.com/2014/02/connecting-to-pi-from-laptops-ethernet.html I think you will find a solution in this method. There are other ways, but this is probably the easiest. Ron KA7U

Two of my KiwiSDR units lost the fans finally. So I took them out, blew out the bugs, and put them back together without the fans. Set the two units on edge, with one end elevated 1 1/2" by using a book for a shim. Both of them ran fanless thro…

A new DRM frequency. Don't know if it is Cuba, but suspect it is based on frequency and signal splatter, along with the low audio. Oh, be nice, anyway, it is playing nice Latin music. Short clip here: https://www.dropbox.com/s/9cxi5q2ksgrx83t/vokos…

I was trying to pick out Pacific Rim MW Broadcasts this morning. I could readily see the carriers on 9 KHz intervals, but the local US stations on 10 KHz intervals overwhelmed the DX audio on all but a couple. So this new extension and nulling techn…

I have 3 KiwiSDR units that have run here for a few years. Start up problems have either come from a power supply starting after a shutdown and the voltage not staying above 5 v at the instant the KiwiSDR tries to start, or the voltage drop in the s…

Never know when Radio Purga will come on, or which frequency. It always seems to play the same recorded music. Ron KA7U https://www.dropbox.com/s/bi6mao9n0e2d9un/vokoscreen-2020-11-05_20-09-15.mkv?dl=0

I've been peeling off the sticker and dropping some Hoppies gun oil into the little hole. Fans keep on keeping on, albiet a bit noisy when first starting, but then quiet down when up to speed. Ron KA7U

The power supply needs to provide 5v + at 2.1 amps or the KiwiSDR fails to start after an upgrade. So check that. Sometimes a power supply is adequate but the power cord has small wire and drops the voltage. Ron KA7U
-
Is this material aluminum or another alloy? Looks like you fabricated this design. Maybe you will publish it. Ron KA7U
-
Batteries often use buck converters to hold the voltage at 5v. So a battery pack is not necessarily a better option than other power supply units. Ron KA7U
-
Mark, You did terminate the antenna input with a 50 ohm resistor? Then changing power supplies might show variances of power noise. You can connect direct to the KiwiSDR, computer to KiwiSDR, except when using Windows 10... ( http://kiwisdr.com/quic…

Looks interesting. How do you plan to connect the fan? Ron KA7U

@jks , I'm no longer managing to produce the error. It must be sort of a game of "whack a mole" for you. Ron KA7U
