F1JEK might want to specify which router he has - I don't think all routers on the market have DDNS capability built in. My Huawei E5186s 4G modem/router for instance has not.

What the KiwiSDR doesn't have, but most other SDRs and receivers do have, is an attenuator. I understand that these are relatively easy to make, and be placed in the antenna feedline. I found a couple fixed value attenutators during an internet sear…

But I understand from your first response that an attached GPS will eliminate the timing error? If that is the case, I don't really see the need for any other solutions. Bjarne

Yes, I should have considered the effect of the absent GPS antenna. Some may wonder why absent, the reason is that I'm running the KiwiSDR on a metered and capped internet connection with no antenna, just for measuring usage.

Good work John. A DX-er can't have too many clocks.
-
See the point, no problem.

Thanks Ron. As far as I can see, my TPLink TL-MR6400 is not among the supported devices for DD-WRT. Bjarne

Norway DST also wrong like Hungary. Partly off-topic but still clock-related: Would be nice to have seconds too. If you're waiting for the top of the hour ID, and waiting to start the recorder... Bjarne

John,yes, that is a concern. It's difficult to estimate what an average month will consume. I've decided to start with a 10 GB cap and am prepared to raise to 30, but that's when it's beginning to hurt my wallet. Goarounds would be limiting the numb…

Well, my s/n 1150 has been "private" since I got it, because my mobile broadband ISP has been unable to provide an APN which supports port forwarding satisfactory. I've now ordered mobile broadband for another ISP, and have hopes that the …

Agreed. Dongles are toys. KiwiSDR is an excellent choice for a tight budget. You might want to check out RSP2 and Afedri SDR-net as well but they are 12-bit and prone to overload. Bjarne Mjeldearcticdx.blogspot.com

It may seem like a silly question to ask, but is the GPS antenna facing the sky? Like being positioned outside? For comparison, mine hangs in the antenna wire just outside the window, probably far from ideal, but the attachment shows what it looks l…

Unfortunately, not all routers allow you to lock the MAC address to an IP address. My Huawei 4G router is one. So the option to do this within the Kiwi is necessary.

I don't think there are any 240VAC wall wart linear PSUs available anymore. I bought some branded Friwo from Germany some years ago, but they are no longer available, possibly due to EU regulations. And they were only 1A, so would need to run at max…

That was a cool gadget John. What would be extremely useful was if one could make a script to automatically change antennas at given times.

Chrome itself is a memory eater. I had repeated Chrome window crashes when I ran the Kiwi on a different PC (an old Win7 Dell Latitude), but it runs fine on an i3 Intel NUC with Win10.

1.34 has been running unattended for some time now, and uploading spots seems to do fine.
-
The difference between your test and what happened at my place was that both the Kiwi and the router powered off, and the Kiwi most likely powered on before the router. I believe we discussed this a while ago, though I can't find the email exchange …

Testing 1.29 now, seems to work fine. Will take a while to see if the original problem is solved :-)
-
I should add that decoding inside the wspr module continues as normal. I do a routine of reloading the web page every evening, and that seems to work ok.
-
Inspired by KA7U's post I decided to test this myself. Yes, it works, and wow how neat not to have to wait for an ID! First time I try this out. Bjarne Mjeldearcticdx.blogspot.com

A general comment re. 24-bit vs. 16-bit IQ: I've done comparisons of Winradio Excalibur Pro 24-bit IQ and Perseus/NetSDR/CloudIQ 16-bit IQ. Very unscientifically speaking: You won't hear more with 24-bit IQs when DX-ing. Even very weak signals near…
