W1EUJ: /* KiwiSDRs run by HFU Members */

= Overview =

The KiwiSDR is a 14-bit wideband receive only HF software defined radio that can receive the entire 10 kHz – 30 MHz VLF/LF/MW/HF spectrum. A large number of these receivers are available online for use by anyone with interest. A [http://sdr.hu directory] and a [http://sdr.hu/map map] of these receivers is updated on a regular basis.

= KiwiSDRs Admin Tips =

== Power Supplies ==

One solid option for a nice regulated 5vdc power supply are supplies made by Acopian. Beerus Maximus found one of these supplies on eBay for $35, model number 5EB200. The list price for this supply is $170(!)* but the one Beerus got was like new. Search "Acopian" on eBay for deals like this.

== Set Static IP Address ==

You may want to set the IP address of your KiwiSDR statically, rather than a dynamic DCHP address obtained from your router. Go to the Network tab on the KiwiSDR admin page to do this.

== GPS Antenna ==
The antenna that comes with the KiwiSDR works, but can be marginal, especially when used indoors. I bought [https://www.amazon.com/gp/product/B00LXRQY9A/ref=oh_aui_detailpage_o00_s01?tag=blackcatsyste-20&linkCode=w00 this antenna ] from Amazon, and it seems to work better. I also found that it helps tremendously to have the antenna sitting on a metal ground plane. A simple small aluminum baking sheet works great. I carefully adjusted the location of the antenna on the sheet, as well as the location of both (they are sitting on a shelf) for maximum signal(s) from the GPS satellites.

I just replace the pan with a sheet of aluminum foil, and that seems to work even better.

== Enclosures ==

An all aluminum case is available from [https://www.seeedstudio.com/KiwiSDR-Enclosure-p-3012.html Seeed Studios] that includes a small cooling fan.

== DX Labels ==

DX Labels can be added to help users quickly identify and choose frequencies, automatically set passband, mode, and extension, etc. Users can click on a label and the receiver will be set to the parameters you choose. Only administrators can add or make changes to labels.

To add, edit, or modify labels:

Press and hold the shift key and then click on the label bar to add a new label. To modify or delete an existing label, press and hold the shift key and click on the label you wish to change.

* The Freq and Mode fields are taken from the receiver's settings when you add a new label. These can be edited if desired.

* The Ident field is the text that is shown on the DX label bar. HTML tags (e.g. <nowiki><br></nowiki> to make two lines of text) can be used to make labels more readable if desired.

* The Notes field allows for additional information to be displayed by hovering the mouse over the label (such as day or time station is active).

* The Passband field can be set by specifying it in Hz.

* The Extension field can be set by specifying an available extension

== Command Line Tips/Tricks ==

You can SSH to the Beagle controlling your KiwiSDR, and login as 'root'. There is no password, by default.
