 I also have a Kiwi SDR online for public use. There are sources of RFI trouble here but I'm working on finding where it's coming from. Also, for some reason my Kiwi is listed on the website as three different URLs! I sent an email to the support people regarding this. Hopefully they can fix this for me.

 The link to my Kiwi is http://joeflips.hopto.org:8073/   Please let me know what you think of my Kiwi reception and what the RFI problems might be. Thanks and Happy Thanksgiving guys!  ;D

 Antenna: 135' all band dipole up about 40'

Hi Joe,

You are about 50 miles ESE of  my location and we are both hearing LW station on 252 kHz from Algeria. I don't normally hear much LW here but conditions are good into our area tonight.

Hi,
 Thanks for the LW tip! I don’t hear much LW here either but I can hear 252 tonight, this is my first time hearing music and spoken word in the longwave band. I checked out your Kiwi and heard it there also.

My Kiwi is here   http://tokenradio.proxy.kiwisdr.com:8073/

Let me apologize right now for the noise on it, I have it setting right next to some RFI sources.  I have plans to move it away from the noise, but have not gotten around to it.

Here's the link to my Kiwisdr: http://strangebeacons.proxy.kiwisdr.com:8073/

Update: I have taken my KiwiSDR offline due to some extreme RFI in my radio shack. I'm not sure when, if ever, I'll get it back online.

A second receiver has just been added connected to the same antenna as the first receiver. This has doubled the number of available user slots. If the first receiver is full it will automatically transfer you to the second one.  :)

I have a public Kiwi at: http://midtn.dynu.net:8073
It is in a noisy environment with a sub-optimal antenna, which puts it low on Chris' survey list.
However, it is there for anyone to use. After the Ken Burns series "Country Music" ran on PBS last fall,
I've seen an increase in connections, world-wide, to WSM 650 AM, which I can hear on a wet string from here. :)

In an effort to improve the antenna situation, yesterday I set up a MLA-30 from e-bay. I mounted it
on a 10' piece of 1" PVC water pipe, with 1/2" cross arms and found the perfect temporary mount - the
1" PVC fits nicely into the umbrella hole in the middle of the deck table! That also puts it ~the same height
above ground as the present "kinda 20 meter", "kinda dipole" that the Kiwi has been using.

First impressions, totally subjective comparisons from listening around, is: above ~10 mHz, the dipole is better;
below ~5 mHz, the MLA-30 is *mostly* better. Bottom line - the MLA-30 is going into the shed until such time as I
need / want an antenna dedicated to <10 mHz, or I run into someone who has NO antenna and needs something,
anything. In my *never humble* opinion, save your $$$  :(!

PS - I have read reviews that said the Bias-T system is noisy and I found that it was not bad - except -  ~10 kHz - 170 kHz
where it generates noise that is ~30 db above the noise floor. I also tried powering it from the Bias-T connection on my RSPDuo
and saw the same result so I think the noise is NOT due to the switching wall-wart I initially powered it with. At night,
I can copy WWVB @ 60 kHz using the dipole; NO WAY using the MLA-30.  --- Just my >2 cents worth!
