I wonder if this is related to the financial trading firms using shortwave radio links to shave a few milliseconds off comm links, for high frequency trading purposes (high frequency as in lots of financial trades, although in this case it also refe…

Same here, I would not mind it if someone contacted me in advance, mentioning why they would like to make extensive/long term use of receiver(s) here. But there's a bit of an "entitlement" mentality amongst some users.
-
I have a different antenna on each KiwiSDR here, so perhaps they wanted to see how reception varied between antennas? Assuming they had some rational purpose in doing this, which might not be a valid assumption 😀
-
Masking is indeed a great feature. I had a recent issue with someone from Taiwan sitting on all seven KiwiSDRs here, monitoring CHU. Sometimes for 12 hours straight. As CHU is something legitimate users might want to listen to, masking was unfortun…

The diurnal changes in SNR scores are interesting to observe, below is the KiwiSDR with a 400 ft south directed Beverage antenna. Somewhat different results on the other KiwiSDRs with different antennas, as expected the 11/10m dipole is pretty disma…
-
It looks as though whenever a KiwiSDR gets updated, the SNR history is cleared. Any way to preserve this information across updates? It might be helpful for viewing long term trends/patterns. Thanks!
-
Retaining a week's worth of SNR data is a great addition, since each individual reading fluctuates so much, thanks! I wonder if there is merit in perhaps including the average of all of those readings on the status page, rather than just the most re…

About a year or so ago I played around with the trying to estimate KiwiSDR SNR, using the existing (95th vs 50th percentile) code as a starting point. I played around with various methods, comparing the results to what the overall spectrum "loo…
-
Some random data points, maybe related, maybe not: I run an SSTV decoder 24/7 on one of my KiwiSDRs. I do not use a browser, I have an app (KiwiKonnect) that directly connects to my KiwiSDR and routes the audio to a virtual audio cable. In the past …
-
Thanks! I just ran some tests here, and the camp parameter is being respected. Audio playback on Safari in camping mode also working as expected. For a moment I thought there was an issue with one of my KiwiSDRs, but then I checked and saw it was st…
-
Some great additions, thanks! Since I have a redirect page users are sent to when a KiwiSDR is full, which is a list of all my KiwiSDRs so they can choose one, I added another option to the links on that page, with the /?camp suffix on the URL, so …

I used to have a local (WTHU 1450) here in MD that ran C-QUAM, but it looks like they no longer do per that list. I just sent them an email to confirm whether or not they do. - UPDATE: They confirmed they no longer transmit C-QUAM. I happen to know …

FWIW, those three new USA/Canadian distributors all seem to be the same company. Still, not a bad price if they actually have stock.
-
Kinda curious, Mouser was showing 25 in stock yesterday, now 26. Maybe someone put one in their cart and then didn't order. I'm surprised they have not sold out already, usually demand far exceeds supply. I did my part by posting on Twitter and Face…

Seeed is showing 10+ in stock as of 1830 UTC 1 Dec 2020. So I guess those units made it through final test 😀
-
My shack is on a second floor as well. But all of my coax cables run at or below ground level between the shack and antennas, where they are grounded several times. It really does make an improvement. RFI issues, especially common mode, are often &…
-
Awesome. As a part time MW DXer, I look forward to this!
-
I do nearly the same thing, I got a bunch of CATV F connector grounding blocks off eBay, attached directly to my ground rods. Short, direct, and low impedance.

Speaking of LZ1AQ amps, several years ago I built a Crossed Parallel Loop antenna (2m x 2m total size) feeding an LZ1AQ amp. Worked great. After some time the amp died due to moisture (my fault not LZ1AQ's). I replaced it with a certain 3rd party co…
-
Yes, I agree, the recorder always respecting the squelch is a reasonable solution. The squelch is working great on the CB band, it's very worthwhile addition, thanks again for adding it!
-
I was thinking about this, and it gave me an idea. Sorry, the idea means a KiwiSDR feature request :) As it is now (I think) any KiwiSDR receivers that are password protected are not available for public use. This means in many cases they potenti…
-
Squelch is a great addition, thanks for adding it! Testing it now on the CB band.
-
Thank you! Perfect.
-
The iframe extension is very handy, I use it to embed the HFUnderground.com chat. Is there a setting to change the name of the extension from iframe to something else? I figure if I could change it to Chat, it might get more users. (This could apply…
-
At least I know now that I can shelve any plans to further raise the height of the outside GPS antenna to improve coverage to the north. Speaking of GPS... I have the one outside high gain antenna feeding my Thunderbolt 10 MHz reference as well as…
-
Thanks for adding the ability to set the default color map. btw - I also really like the SdrDx mapping. Perhaps because I am a long time SdrDx user :)
-
Thanks for mentioning the "polar hole", John. I mistakenly thought it was due to the line of evergreen trees directly to the north of my outside GPS antenna :) (Image)
-
I routinely check http://rx2.wa2zkd.net:8073/ in the late afternoons to see what propagation from Europe will be like later on here, for pirates in the 5-7 MHz range. Your KiwiSDR is about an hour or so ahead of mine here in Maryland for those signa…

Perfect, thank you!

Is it possible to set whether auto or manual mode is enabled as a default for visitors to the KiwiSDR? Auto mode (at least on my KiwiSDR) seems to produce a too difficult to interpret waterfall, at least with the default gain settings.
