Hello, it's too imprecise to pronounce. If the internal resistance of the 12 Volt generator is low, its voltage drop for 3A will be low. So, when there is a high intensity, it will heat up. the regulation device will have to dissipate 20 Watts, a b…

Hi, There is currently a very strong solar storm, maximal level 5, of exceptional intensity. The Northern Lights were visible last night in Europe on the 45th parallel. And numerous radio disturbances were caused by this magnetic storm. All night, H…

Good morning, when there is a long cable length, I would tend to choose a GPS antenna with 40 dB of gain, and especially a low loss cable. Here, the cable is 30 meters long, if I want the two GPS antennas to be exposed to a corner of the sky. The Ki…

No better here, it went down to 7 dB(all), 6 dB(HF) at 9:20 GMT. I currently have SNR 8dB (all), 8dB(HF) at 10:41 GMT. Never seen it, so strong. Something curious is happening to the sun. Regards, Philippe

at 9:33 GMT, in Trémolat in Aquitaine, France. It goes back https://forum.kiwisdr.com/uploads/506/DDL69BIM098H.jpg

It's even worse this morning. At 9:16 GMT, I had nothing, here in Trémolat in Aquitaine, France. It is believed that the antenna is disconnected. I checked, this is not the case. There are only VLF and LF that pass and an RF source transmitting on 1…

Thank you very much Martin for this report. Here too in the South-West of France, it was very bad. My two Kiwis have never had SNRs this low. Storms (rain, hail, lightning) return next week. This year, they are very early and particularly intense, w…

Dear all, Martin, thank you very much for the document. This afternoon we had a very big storm problem. The lightning didn't stop falling, permanent flashes. 9000 houses without electricity around me, high voltage lines down on the train tracks. In …

Hello, Interesting. It's curious. On my Kiwi, I don't notice any change when we go to 10Mbps. Maybe there is a ground loop somewhere in your installation. I use 6 meter shielded CAT6 cable to the Cisco switch. Cable S2CEB, CAT6 F/UTP, This flexible…

Good evening everyone, exactly. I would like to add a few ideas. Be careful with power supplies intended for analog audio electronics and HiFi, whether they are made for professionals or amateurs (power supplies for audiophile). In order to protect …

Dear John, Dear All, The « Users » tab is a great option. Thank you very much for this development. Now, the display here (v1.671) is capricious: sometimes the list is displayed, sometimes not, even after waiting for a certain time. On my Kiwi, the …

Thank you very much Martin. I try to do the best. For the antenna, I found this location which seemed appropriate to me: a small plateau of limestone earth, slightly rounded, well clear towards the 4 cardinal points, far from the first houses. I had…

What's your KiWi URL ? Good luck, Martin Dear Martin, Thank you very much. It is : http://sdr.autreradioautreculture.com:8074 QTH : Trémolat, Sud-Ouest, Périgord, France Best regards, Philippe

At the bottom of the vertical antenna I installed a HiZ to LoZ transformer. I added a buffer to obtain the same output impedance for all frequencies (75 Ohms). To send the signal through 250 meters of coaxial cable (75 Ohms), the impedance must be v…

My receiving antenna is too powerful. With the Kiwi 2, I have to reduce the gain by -7 dB. if I don't want to saturate the converter. Even with 250 meters of coaxial cable between the vertical antenna and the Kiwi receiver. The antenna noise is lowe…

Hello, :))) Attention. If I add gain... I will move to the front, to the top of the list. Ahaha ;) Best regards, Philippe

Hello, for information, I use an iPad Pro (2022) with IOS 17.4.1. You must put the /?m option. The result of the DUMP command on this Ipad is as follows: HTTP_USER_AGENT => Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHT…

hello, here in France, the connection to your server is very stable, without dropouts. Your computer system works quite well. Well done. On the other hand, on the HF side, there are many local parasites, and a lack of sensitivity. You will improve r…

:)))), excellent idea. Thanks John.

https://forum.kiwisdr.com/uploads/942/SD7KLE5BE11E.jpeg hello, for a connection to the iPad, I use the mobile option: .../?m and it works very well with many versions of IOS. I always use my iPad to connect to the KiwiSDRs and also to manage mine. k…

This possibility is excellent. A very nice option. Thank you so much.

Hello. Thank you very much for asking this question. For my part, the name of the city is useful for identifying regular users, because very few people provide their identifier. Even if the name of the city is not exact (always big problems with geo…

Hello, just my experience. After several tests, I chose two Condor HBB512-A+ power supply (SL Power Electronic). The regulatory tests are excellent. It delivers 5 Volts for 3 Amperes (KiwiSDR) and 15 Volts for 0.5 Amperes (active antenna). The two K…

Hello, very beautiful creation and well designed, well thought out. There is a lot of security and that's good. Sharing the constructions and achievements of each of us interests me very much. We learn some good ideas there. Thank you very much, May…

@NJC : yes, the solar panels are bryant on radio frequencies, because of the inverter switching system. Now, I filter all this noise with appropriate filters, on the solar panel side and on the sector grid side. In addition all high voltage cables (…

@kb7rqq, Todd, thank you very much, I'm trying to do the best. There aren't many KiwiSDRs in the area where I live. there are large natural spaces, rivers, forests and meadows. My closest neighbor (500 meters away) is American (Massachusetts). He ch…

The isolated pylon (a height of 11 meters) : https://forum.kiwisdr.com/uploads/055/EA4QC8KRQJ63.jpeg High impedance to low impedance transformer, and 20 dB amplifier to compensate for the loss of 251 meters of 75 ohm cables. 20 dB is too much. I hav…

For the 251 meter cable, I chose satellite TV cable, with 5 layers of shielding. It's 75 ohms, it doesn't matter. This cable is not expensive. On the other hand, I buried it 250 meters, 30-40 cm underground, in a 40mm sheath. The RG 174 is too weak.…
