Hi Jim, "I also use the S-meter extension for related things" So do I - I just wish it had better resolution for antenna testing. Average, Max and Min traces would be good too :-) Regards, Martin - G8JNJ

Hi John, It now works OK on the iPad on all three test sites. The mute button on the top menu is appreciated. However the Spectrum button now seems even more out of place to me, I think it should reside of the waterfall page next to the new 'Slow De…

Hi All, Some other thoughts. -0.5 seems to be a good compromise. However why not vary the time constant with the waterfall speed slider. So that when it's running very slow the spectrum value is -0.2 or longer and when it's running at the normal spe…

Hi John, Would it be possible to add something like a fast acting white 'peak' value 'outline' behind the coloured spectrum graph, so that it's easy to see fast changes whilst still retaining the decaying 'what was there' coloured spectrum graph. …

Hi Jim, Agreed, I could just hear something like a very brief snatch of voice type modulation (not white noise or digital buzz) when listening on one frequency. Could be fishing boats with some basic encryption. Regards, Martin - G8JNJ

Hi John, The LMS "denoiser" and "autonotch" filters work quite well and are a very welcome addition, so thanks for that. However I can't open any of the three test sites on my iPad running Chrome. The URL resolves OK but I just g…

Hi Frans, OK all understood. The 'Less buffering' and 'Compression' are associated with audio latency issues that were resolved by John some time ago. These are likely to be removed in the near future. http://forum.kiwisdr.com/discussion/comment/246…

Hi Christoph, OK - thanks for the update. Both my Public and Private KiWi's have the same build and the antenna switching extension installed, so I don't know why there should be a difference between the two. Anyway I've rebooted the Public KiWi to …

Hi Frans, Welcome onboard :-) Have you looked at this document which is linked from the 'pop out' information page on the KiWi http://www.kiwisdr.com/quickstart/ There are is also a 'Bug' list that folks generally refer to before requesting new fe…

Hi John, Would it be possible to add a 'high contrast' button on the new waterfall tabbed page so that the ?sqrt=2 (and other ?) option could be selected directly from the GUI interface in addition to a URL extension ? Regards, Martin - G8JNJ

Hi Jim & Pete, "I had a post about my idea a week or so ago. " Yes I saw that. I wasn't disagreeing, I just though that putting the modes on a separate tab would provide more space for the drop down, and any other enhancements. "O…
-
"I hope we'll see mode pulls downs soon" Maybe they should be on another tab ? Regards, Martin - G8JNJ

Hi John, That's a neat fix. It's a lot better than the current layout, and it has a dBm indication on the S-Meter too Yeah :-) I have had a good play with it and it seems to work well. Some (very minor - and somewhat picky) observations for further …

Hi Jim, OK thanks. Regards, Martin - G8JNJ

Hi Jim, Maybe, but I think the waterfall sample rate is aliasing with the actual hop rate so I don't know if what I'm seeing is a true representation of the time spent on each frequency. It's a bit like the hoppers I can see on UHF Satcom around 243…
-
Hi Peter, I also think a headless mode would be useful, but what you are describing seems a bit messy / complicated. Wouldn't it be easier to simply use kiwirecorder and loop the record file to playback and gradually overwrite it as it's being recor…
-
Hi John, I couldn't find an obvious combination of scrolls and zooms that triggered the problem. It may just be a browser / PC hiccup associated with Windows memory usage or something similar. Don't worry too much about it - I'll update the thread …
-
Hi John, OK thanks for the info WRT the WF transfer rate - I hadn't spotted that, so I'll try the slower rate with one of my older 'netbooks' which otherwise struggle when running the KiWi webpage. Regards, Martin - G8JNJ
-
Hi Jim, Yes that was all of it, it was fairly well confined to a 100KHz wide chunk of spectrum. There were at least two stations transmitting in turn (one was weaker than the other) with different length transmit periods, usually lasting from 2 to 2…

Hi John, Sorry I don't have WIN 10. Chrome Version 63.0.3239.84 (Official Build) (64-bit) F5 is a browser refresh. Regards, Martin - G8JNJ
-
Hi, I think this would be useful - at the same time would it be possible to stop the waterfall streaming to save bandwidth. Maybe the spectrum button could be modified to toggle between full screen spectrum / full screen waterfall / waterfall and sp…
-
Hi Peter, That's a lot better. The extension basically works. Autosave waterfall opens a full screen image of the waterfall in a new tab every time an image is grabbed. This results in quite a lot of tabbed pages if you leave it running, but at leas…

Hi Peter, Both Chrome and Safari on the iPad. Regards, Martin - G8JNJ

Hi Peter, Unfortunately it's not working properly on the iPad. It's the same problem as before. The first image tries to save as a full webpage and overwrites the KiWi page. Everything else seems OK when using the PC and various browsers. Regards, M…

Hi, I'd also like to add the KiWi ID to the time and date, so that it makes it easier to use the data at some later date if a centralised database is ever established. Covered in these previous threads. http://forum.kiwisdr.com/discussion/comment/25…

Hi, This is a known issue in the bugs list. * Javascript stops on "sendto:" email links. This is a browser problem that may never be fixed according to stackoverflow.com Regards, Martin - G8JNJ

Hi John, I've been trying the noise blanker against a variety of different noise sources. I notice that in most cases the noise gate is better at 100uS and (for me) actually worsens the performance at much higher values >3000uS. I wondered if oth…

Hi John (ZL1GWE), I'm not sure if you intended to send your last post ? However the use of DF77 (time station) was just for test purposes as it's location was known, it was a stable time reference which was useful for calibration and being such a lo…

Hi John, It works very well. I've tried it on some broadband noise (2-4MHz) I have from the nearby quarry during the working week, and it virtually eliminates it. I also tried it on a couple of SDR's with some Switched mode power supply noise, and a…

Hi John, A couple of thoughts on this subject. SDR's seem particularity prone to high level pulses of coherent energy spread across a wide spectrum. Even if the pulse doesn't overload the ADC, the combined power is often sufficent to overide signals…
