Tech Minds YouTube review questions #1
Questions from the Tech Minds YouTube review:
It only goes up to 30MHz?
Yes, it was designed as "shortwave" receiver covering 10 kHz (VLF) to 30 MHz (32 MHz with reduced specs). It is possible to use a downconverter ahead of the Kiwi to cover VHF/UHF and a number of public Kiwi owners have done just that. See here: non-HF Kiwis
I’ve connected my kiwi sdr but it does not show only says “No KiwiSDR(s) found for your public IP address”. Does anyone has the same problem? How to solve this?
The my.kiwisdr.com page will only show information about your Kiwi if the network your Kiwi is attached to has a connection to the Internet at the time it starts up. Also, that network must have a DHCP server to assign a local IP address to the Kiwi. Try restarting the Kiwi. Our documentation describes other methods for determining the local IP address including decoding the pattern blinked out by the 4 blue LEDs.
Why does it not have wifi, so we can cut down on the cord clutter and make better placement choices?
The BeagleBone Green we used back in 2016 did not include WiFi. There is something called the BeagleBone Green Wireless, but it is not physically compatible with the Kiwi board. Instead, we recommend using a TP-Link TL-WR802N WiFi nano router which can plug directly into the Kiwi's Ethernet connector and your WiFi network. It requires minimal configuration and none on the Kiwi side if you use DHCP to assign the Kiwi its local IP address. Future products will definitely include WiFi.

v1.807,808
I think this is a conflict between who controls the LEDs during the sd card backup script running. I believe it's on my list of things to fix.
Update: Okay, fixed for the next release.

v1.807,808
Yep, a typo made in the Verilog code last July if you can believe that. Didn't show itself until I built v1.807. Fixed in v1.808..

v1.807,808
Instructions for the Debian 11 upgrade procedure described below are here: http://kiwisdr.com/quickstart/index.html#id-D11-upgrade
From the CHANGE_LOG file:
v1.807,808 April 10, 2025
Admin backup tab: Added button to create a Debian 11 upgrade SD card which includes all
customizations from the current Kiwi. Intended to be used by Kiwi's still running Debian 8.x
Greatly simplifies the upgrade process by automating these formerly manual tasks:
Checks for sufficient free disk space.
Downloads Debian 11 image file from kiwisdr.com with integrity check (checksum).
Writes image to SD card.
Copies configuration from Kiwi's kiwi.config directory to SD card.
SD card is now ready to be use to re-flash this Kiwi to Debian 11 on the next restart.
Including if you were to immediately restart after the sd card creation completes.
=> Everyone is strongly advised to upgrade to Debian 11 from Debian 8.
At some point we will no longer provide software updates to Kiwi's running Debian 8.
Complete rewrite of the admin webpage grid & location processing code. (thanks studentkra)
FSK extension: Added preset menu. Complements the existing ability to set presets in the URL.
Reduced minimum name/callsign (ident) length from 16 to 8 characters. (thanks LIN)
Admin status & antenna switch configuration page now displays antenna status. (thanks LIN)
Updated to EiBi-A25 database. (thanks jgreentn)
External extensions being present will always cause a compile from source. (thanks DL3LED)

OT: Time Signals for clocks - MSF
That README page is slightly confusing because the picture of the air-core coil and first schematic appear adjacent to each other. The two schematics refer to the second picture which shows an "AM loopstick" style ferrite coil which could easily be 700 uH I would imagine.
Brings back memories of when I ran a LOWFER beacon on 175 kHz back in the early '80s. 1W input using an IRF510. And an output coil wound on a 200x500 mm coil form using Litz wire. Heard all over the western US. Was it really that long ago? Am I really that old? What happened!
