https://forum.kiwisdr.com/index.php?p=/discussion/comment/19587#Comment_19587 Well, finally had time to fix it. Turns out it was a fuse inline with the AC input. :-D
-
I've been using the HFDL extension, and yes, it's quite impressive. I spend a hour in the evenings scanning through the bands. Its good down time.
-
I built a nice linear power supply. Some parts were new, some old. It died this morning. :-( It will have to wait until the weekend. Back to the Apple wall warts.
-
Thanks, Martin. I did add the attachment as a ZIP. (thought I did) File share instead
-
True, I didn't spend a lot of time on it, as I was scanning the bands having a coffee before work, and noticed how strong this signal was. Next time it comes up that strong, ill launch TDoA and do a bit more research. Ill take my tinfoil hat off n…

Ah nice. its being maintained by priyom!
-
Seems rivet is long abandoned and the binaries are no longer available and only 12yr old source code is there :-/
-
Ah good to know thanks both! Ill keep beavering away. I got some gibberish from a signal the other night then after about 30 mins, gave up making sense of it. :-)
-
Ah yes, its public http://21996.proxy.kiwisdr.com:8073/ Based in Napier / Hawke's Bay / New Zealand. Not that many of us in this region.
-
I used my own KDSR2 Priyom is a great site for all things related to these stations
-
Cant find that signal on any other Kiwi's around Hawke's Bay.
-
It is, yeah, in Napier.
-
I assume these are "knock offs" or made from your schematics, board layout etc found online?
-
A quick update. I received the DC power supply, gave it some tests and it seems like a nice stable 5.18V on the output. I replaced the two Apple bricks, one for the KSDR and one for the Bias Tee, and connected them to the new linear DC supply, and …
-
Thanks for the feedback, and apologies for my knowledge gap here on the development of the device.

Hi Martin, That was actually going to be my next option, however I will need to get a good length of coax as a run from there to the garage would be 60 odd meters. Off to Jaycar this weekend then :-D Cheers Sean
-
I have moved the loop antenna to the rear of the property away from the house, and I have a small room in the rear of the garage which doesnt have much in the way of electronics in it where the KSDR resides, and I also put that into a metal box (wel…
-
Brilliant, really appreciate the advice!
-
Make sense. To be honest, the antenna is a cheap MLA-30+ which in fairness, does an excellent job of increasing signals and reducing the noise floor, and given I live in a suburban area, I cant complain for the price. My next step for an antenna th…
-
So, anecdotally, I "think" its the Apple power supplies. Unfortunately I only have one pure DC supply (battery pack with USB), however when I swap out one of the Apple bricks, the noise almost dissapears. When I switch between the Bias Te…
-
I do have a DC battery pack - I will try that and see if the noise is still there. It could also be coming from the loop antenna Bias T as it too runs from an apple brick (separate) - Ill do some swapping around in the weekend.

https://forum.kiwisdr.com/index.php?p=/discussion/comment/19395#Comment_19395 Makes sense. I'm using genuine Apple USB 10W power bricks. I think I might build a linear supply.

https://forum.kiwisdr.com/index.php?p=/discussion/comment/19391#Comment_19391 Please don't release the KSDR 3 just yet, my still asking for forgiveness for getting the 2 :-D
