Thanks John.

The issue I mentioned above with the Vivaldi browser not saving KiwiSDR recordings has been identified. It is mentioned here: https://forum.vivaldi.net/topic/95927/kiwisdr-recording-functions-don-t-work-on-vivaldi/4

That would be good... Otherwise you have to dig through the menus and check things, which is a bit tedious. It's easy to do a quick test on something and forget to change settings back. Zeroing the samples on an IQ signal probably isn't the best way…

I was quite distracted today, so now I'm wondering if I did something stupid - like noticing the Kiwi NB was on, then turning it off - then later thinking it was never on. So far, turning the Kiwi NB on is the only way I've found to duplicate the re…

Hi John, The IQ glitches appeared to be strongly correlated to when "Attn" displayed. Looking at the IQ file, there are rows of zero-valued samples occurring when the glitches happen. Is it perhaps from some other update to the firmware? I…
-
It looks like the auto Attn is indeed causing amplitude and/or phase glitches on the IQ waveform - and my NB code was trying to blank it as noise. Even with the NB disabled the glitches are still audible. A step change in gain ahead of the ADC is a …
-
The automatic attenuation function was constantly flashing on the KiwiSDR I was using today in IQ mode. There were glitches happening that sounded like a badly adjusted Noise Blanker but further investigation suggests that's exactly what it was... T…

This problem I've described appears to happen when the particular KiwiSDR has it's internet connection overloaded (too much data to send for the available network bandwidth). It typically happens with a higher number of users, and only on certain Ki…

Are the SAM options only supposed to change in SAM mode? In SAL, SAU, SAS and QAM modes the menu causes no change - it keeps using the setting from SAM mode. This was confusing at first... (Firefox 104.0.2 64-bit Win 7)

Thanks John, I'll try to run some tests on it... Looks good so far. Daz

Well, on April 10 I ran an hour long test with ALL FOUR Iceland Kiwis running at the same time, (plus a couple of other Kiwis for good measure) and had a total of 12 Firefox browser windows open including Facebook and Twitter, plus IE and Skype also…

Regarding KiwiClient: KiwiClient would be a great way to record, though if the signal can't be heard live simultaneously that could be a problem in some applications. Even better if KiwiClient can save the waterfall and s-meter data as well as the I…

I'm in Australia by the way. My friend who observed the same problem on Chrome is in the UK.

But surely a slow network connection wouldn't slow down the UTC clock on the Kiwi? And what about the browser still receiving data 20 mins delayed, and after it had already disconnected? Surely the network would never buffer that much data...

6GB RAM, SSD with swapfile on it. The IQ recordings are typically a max of about 350 megs each for two hours. The RAM appears to swap out as the recording progresses. This problem seems less related to the recording duration than to the particular K…
-
I do monitor RAM use but it always creeps up because it records to blob memory. I can run the ping test if you like.. But I have some more info: A friend of mine has just told me a few minutes ago that she sees this same Kiwi problem happen in Chrom…
-
OK.. This might be useful then... I usually have more than one Kiwi window open (often 4), and normally just one of them will have the bug. The rest will continue working just fine. I think the fact that the Kiwi UTC clock lags behind along with the…
-
@Powernumpty It makes no difference how old the thread is, if the problem hasn't been found and fixed. It's a problem that strikes every once in a while, and things mostly work so you put up with it, and wait for it to be fixed. The bug can't be rep…
-
I see this bug happening on FF 87.0, 64 bit (Win7 Ultimate 64 bit SP1) - and it annoys me a lot. I use KiwiSDRs at least twice a week. If this bug happens and gets severe enough, it can trash IQ recordings. The KiwiSDR UTC clock also lags behind ac…

Is this good enough? http://homepages.ihug.com.au/~daz2002/tech/FT747-clip.ogg This recording is a friend's FT747 with the squelch modified to be linear. It made the radio much nicer to listen to! From 1m 05s to 1m 15s I turned the squelch off to sh…
