There's lots of online SDRs, hundreds by now. While they're extremely handy to use, unfortunately many have RFI/antenna issues.  I'd like to create a listing of hand curated high quality KiwiSDRs (and other online SDRs) on the HFU Wiki. The HFU Wiki! Remember the Wiki !?!? The best kept secret on the HFU!  :)  OK, I digress, back to the topic...

Here's how you can help. Do you have some favorite go-to online SDRs that you use, that do a great job of receiving, with minimal RFI/noise issues?  If so, please reply to this thread with a listing of the KiwiSDRs you use, and what you use each for. For example: stations from what part of the world, which bands in particular, etc. Whatever best describes how you use that SDR. And it's OK if someone else has already mentioned some of your favorite SDRs, please post your uses/observations as well.

I'll compile these onto a page on the HFU Wiki. The Wiki! Remember the Wiki???  ;D

To help my end of the task, for each SDR you list, please give the "name" of the SDR (usually how it appears at the top of the page and in the KiwiSDR receiver list) as well as the URL, and then your description.

For example:
N1NTE / ΣSDR2 - CT/MA Border, Northeast USA
Good reception of pirates for the northeast USA, and the 80m band.

I have enjoyed listening to almost everything on this SDR in London with a Wellbrook Active Loop (No Name):
http://sdr.m0taz.co.uk:8073. The range is from 0-30 mHz
Among the things I enjoy listening is live sports, especially football blocked on web streams is US, on BBC 5Live on 909.

I discovered the above on this listing but I have not tried them all out. 

However, the one in Bedford, UK was pretty decent for all types of listening. (Bedford UK SDR)

Of course, there is the U Twente sdr

Besides sports, I use all the sdr's for European pirates, Channel 292 and other private European broadcasters, and some Governmental Programming that is tough for me to receive in English in the US

Quite an undertaking, resolution?, for the New Year!

I am not a frequent user of remote SDR's but I do occasionally use them to hear a pirate station that I am not able to tune in locally.
I also use them to monitor how my amateur radio signal sounds at various locations around the world.
I am fairly picky about which SDR's I use, they need to be sensitive, low noise, and not overloaded.  They also need to perform well over all of the HF spectrum rather than only covering a band or two.

A lot of the best ones are difficult to access as all the slots are usually full, so this list is SDR's that normally are not full, yet have good performance.
I may be shooting myself in the foot by putting this list here.

I do use Chris' SDR's - http://sdr.hfunderpants.com:8073/ in Maryland - as well as Sigmas - http://sigmasdr.ddns.net:8073/ - near the CT/MA border.
Others that I use in  eastern North America are:
http://rx2.wa2zkd.net:8073/ in Maine
http://w1nt.onthewifi.com:8073/ in New Hampshire
http://raleigh.twrmon.net:8073/ in North Carolina, a little noisier but good sensitivity and not overloaded in Indiana

In western North America:
http://ka7u.no-ip.org:8073/ in Idaho
http://tokenradio.proxy.kiwisdr.com:8073/ in California (Token's Kiwi)
http://ciw321.cfars.ca:8174/ in Alberta (VE6JY)
http://kiwisdr.ve6slp.ca:8173/, also in Alberta

In Europe:
http://server.ol7m.com:8073/ in Czech Republic (excellent station)
http://sdr-bayern.spdns.de:8073/ in Germany, Upper Bavarian Forest
http://fenu-radio.ddns.net:8073/ in Switzerland
http://sdr.tambov.gq/ in Russia

I have not found a good performing HF Kiwi in Australia/New Zealand.
I usually use this one http://tecsunkiwisdr.access.ly:8073/  (at least it is not overloaded)

I also have not found any Kiwis in all of Asia that are consistently good performers. in Japan is sensitive but noisier than I would like.
There was another in Hong Kong that I have used but it seems to be offline now.

I am looking forward to seeing what Kiwis others use (especially in Asia, Africa, and Australia)

+1 for Ct Yankee's recommendation of M0TAZ.

Farnham - KiWi WEB SDR (South East UK | Grid: IO91of)
is pretty good for most stuff (ham, SWBC, etc)

They also have a VHF/UHF SDR (50/70/144/146/430/433/435Mhz) but probably of less interest to users on here.

Both above are close(ish) and equi-distance from my QTH so I use as a check against direct reception.
