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.…

Hello, If you have hectares of land, don't hesitate to place your antennas as far away from buildings as possible, in clear areas. Here in Tremolat in the southwest of France, I have two Kiwi receivers. The first antenna (mini-Whip) is 55 meters fro…

Dears Martin, Jimmy Martin, I admire the reception quality of your system (http://wessex.hopto.org:8075/); it’s a reference. All is well. Well done. Bravo. Subject of the mini-whip : actually on my mini-whip antenna, element of 50cm long by 4cm in d…
-
Hello, I agree with Martin. The plate of a Mini-Whip antenna is too small. In my creation, I did not use a whisk, but a large thick aluminum tube, with a diameter of 40 mm and a length of 50 cm, at the end of a stainless steel pole of 3.50 meters hi…

Hello, KiwiSDR #1121 arrived today after multiple quick DHL stops, Singapore, Bahrain, Leipzig, Brussels, Bordeaux and here Trémolat (France). Mounted in its rack today, it works perfectly. Many thanks to John and the whole team. You are amazing. Be…

Dear All, Here in Trémolat (France), the 162kHz signal is very stable, both in AM and in CW (V1.649. Best regards and Happy New Year 2024, all my best wishes. https://forum.kiwisdr.com/uploads/876/L8OOPOLN25N4.jpg https://forum.kiwisdr.com/uploads/0…

Good morning, for security reasons, I prefer Paypal or a normal bank transfer. I don't use my credit card directly on the internet. When I make a bank transfer, the waiting time is 72 hours, because my bank verifies everything. best regards, Philippe

Hello John, Thank you very much for your announcement. I am interested in purchasing 1 unit “KiwiSDR 2”. If available, 2 units. I just wrote you an email. Best regards, Philippe

Good morning, I completely understand your difficulties. The modern city is no longer silent, in a radio-electric aspect. Too many sources of domestic interference (lamps LED or Neon, power supply, electrical appliances, inverters, etc.). The only w…

Hello John, Dear all, That's very good news. KiwiSDR is a great system. As soon as available, I will buy you one or two new V2 cards for the Trémolat antenna. With pleasure. Best regards, Philippe
