It's not that easy, as it depends on the source, and whatever it is connected to. Especially as John has already indicated that there is likely to be more than one source. That's why I suggest switching off your power at the main board, you will the…

Which IP address ? Your internal network (probably 192.168. xxx.xxx), or the outward facing public IP, which will probably change unless you have paid for a fixed one. You will also need to setup your router for port forwarding. Most of the informat…

Most likely you will, so good hunting. Oh and folks will soon be turning on their cheap Chinese made Christmas lights and decorations, so expect things to get worse for a month or so, until they get packed away again ready for next year. Regards, Ma…

Oh dear, that doesn't sound good. However, from experience. Most noise tends to be conducted, and if it's really strong, it's more than likely to be from something in your own home, or something very close to it. If you can run the KiWi, or another …

Can we hear the noise please ? Ideally an AM recording made on a quiet bit of spectrum. That would provide a lot of clues. Regards, Martin
-
How are you powering the loop amplifier ? It is difficult to tell from your screen grab, but are there any really strong signals present that could be causing ADC overload ? If you tune to an unoccupied part of the spectrum and listen using AM, what…

I just checked mine and the S-Meter shows the correct step sizes. It's possible the IBP steps are not exactly 10dB, or some other factor is coming into play, but if you have a V2, you can test it by tuning to a strong signal and increasing the input…

Oh I quite like that idea. Maybe it could be linked to the user defined memories in some way too, and then perhaps a scan function could be added, with either timed or squelch controlled pause / resume. However, I think John has more than enough to…

Ah OK, like temporary user specific DX labels or were you something else ? Regards, Martin
-
Have you explored the existing user memory options ? Although it does not place markers, it does allow you to quickly recall or skip between frequencies. Regards, Martin

Hi Shane, Whilst looking for the post I mentioned, I found this which may help. I haven't had a chance to try it myself, but it looks promising. https://veducate.co.uk/winscp-elevate-to-root/ If that doesn't work there are additional options. https…

I don't think you will be able to get in using WinSCP. I'm experiencing similar problems since updating the OS version, and WinSCP doesn't provide the option to log in as su. I seem to remember reading a thread about it but can't find it. Also, wit…

Having the SNR measurement switch to the default antenna (or another one that is specified) makes sense. I have noticed that my uploaded SNR measurements vary, depending upon which antenna is selected by a user at the time of measurement. Regards, M…

Yeh, I realised you were joking. If you live in that part of the world, then I'm surprised you can hear anything other than radars :-( The Wave radar you mentioned is very strong in Europe, which is why I thought it must be located over this direct…

Sorry to dissapoint. It's a Wave radar, but it must be a new one, as it's not on my list of European or North American ones.

"And I think the LT1083/1084/1085 stabilizer is a very good and cheap choice." The 5A linear regulators do produce LF noise. https://forum.kiwisdr.com/uploads/768/5OYC6KSJYIJE.png But adding a big electrolytic across the regulated output…

Beware of Ubiquiti radio links using PoE. The DC-DC convertors and plastic housings, can make them very noisy on HF frequencies. Regards, Martin

Most likely during a contest or similar. When some of the big contests are running, like CQ Worldwide, the amateur bands are usually packed. Most contests tend to held during the weekend. https://www.contestcalendar.com/weeklycont.php Regards, Mart…

They sound like the Indonesian / Asian fishermen that can be heard all over the spectrum on odd frequencies, often performing a lot of chanting. The Australian KiWi's in particular tend to be full of them, along with all the HF radars around that re…
-
Yes, you are correct, it is Upstream, which makes more sense, and may be easier to fix.
-
Looking at their spectrum display, it's the downstream DSL, that is problematic, which is odd at this level of amplitude. I wonder if they have their modem, line filters and POTS wiring setup correctly. Regards, Martin

If the antenna details given on http://zl4md.proxy.kiwisdr.com:8073/ are correct, they are using a Mini-whip antenna. These, like most unbalanced antennas, are prone to picking up local interference, which is a pity as they seem to have a reasonable…
-
You make some good points. The company I worked for moved across to Open Source at the behest of the developers, as at the time, it was becoming "the next big thing". However, they didn't have the responsibility of maintaining the end prod…
-
I understand your point, but after buying a KiWi is it really that much to spend ? However, as an alternative idea, I was in a local "pound (dollar) store" the other day, and noticed that there were several small metal storage boxes with l…

Ah, a typical radio club, where the minority of members who actually do things, get criticised by the majority who do nothing, except pick holes in the various initiatives. Been there, done that... My personal experience of the alternatives, is that…
-
Personally, I'd say, don't bother. Put it in a die-cast metal box or a similar screened enclosure. It's much better, as it helps avoid interference to, and from, other devices. Quite a few previous post cover this topic. Regards, Martin

Hi Steve, The KiWi is not calibrated in dBfs as such. If you use the waterfall and S-Meter values I previously posted, it will be close to genuine dBm values. 0 dBm = 1mW into 50 ohms. Try to keep individual strong signals at less than -20dBm and if…
-
I set mine to Waterfall min (dBFS, fully zoomed-out) -110 Waterfall max (dBFS) -20 S-meter calibration (dB) -13 Waterfall calibration (dB) -10 I thought you could also set the Auto waterfall max and minimum levels, but I can't find that option. But…

I agree with Glenn, Most small companies eat into their profits, by providing after sales support. It takes up valuable development time, delays the launch of new products and the additional income stream they can provide. New products are require…

I'd also suggest emphasising the "works straight out of the box" aspect of the KiWi. One competitor is making an attempt at this, so far unsuccessfully, but the majority of previous competitors have not been able to achieve this. Other op…
