  • https://forum.kiwisdr.com/uploads/075/ZGF45R0CWNL4.jpg (Cont'd) no successful recovery with the those commands (./up) offered by @f6bir2 2 . re-flashing kiwi1 w/ v1.486 image was of no use either. Next-to-do : debug step by step w/ electric-met…
  • Hi John, After taking out kiwi1 earlier and re-flashed the v1.665 image, things did not improve. Since the new BBG and another 2nd-hand BBB didn't work either, I thought this was a hardware issue with the kiwi board side. https://forum.kiwisdr.com/…
  • Hi Martin, Once, I planned to install a kiwi at Chang-ning in Shanghai and wanna make it public on www (out of The Great Wall so to speak). However, several friends with cn call signs expressed this sort of attempt might not be so appropriate…
  • Hi John, Thank you so much. No problem I'll find someone's electrical support and follow your guide first. Since I started a business trip today and will be back home after the 25th, so the update will be until about the end of March. B/R,…
  • (Cont'd) https://forum.kiwisdr.com/uploads/418/605VYSDSBP8P.jpg After replacing a new BB/G and flashing v1.486 image, the check results are as follows. This could almost confirm this issue occurred on the kiwi side. 😔 Try finding a paid repair nea…
  • Looking at the new BBG I received this morning, I were pondering after reading this thread... (for replacement of my kiwi1's BBG due to FPGA not responding issue) https://forum.kiwisdr.com/uploads/774/P682Y3WFC4N4.jpg
  • <Cont'd> Currently my kiwi1 is encountering a similar issue (FPGA not responding 0xffff). But unfortunately after separating kiwi/BB (then w/ air gun spray)& carefully putting them back together again, no good progress could be seen. https…
  • Dear Martin, Out of curiosity, I just bought a PA0RDT mini-whip clone. Then I connected PA0RDT amplifier in series to 303WA-2 to see the what might happen to the variation of Kiwi's SNR. It may be because Kiwi has an AGC or automatic attenuation, so…
  • Dear John, Sorry for being late. I drove back to my old house last night and took it back to Hsinchu (because it's sure that port 8073 here was already a DMZ) for kiwi1 test. As shown below, the file kiwid.aout could be seen via putty w/o problem. …
  • Hi Martin, Due to the tight and solid structure of 303wa-2, it is almost impossible for me to get any answers without using a machine tool to disassemble the working part. I once referred to the exploration by several Japanese radio enthusiasts, ho…
  • https://forum.kiwisdr.com/uploads/862/Z82ATWKXKFSW.jpg Kiwi 2 works normally after installation. Since it came with a reverse proxy by default, the setup is rather simpler and eliminates the need to apply for one more ddns account. It’s really gre…
  • Hello Jolo, here I used Apexradio 303WA-2, which is a easy-to-install passive antenna , so it doesn't require electricity and easy to maintain. The price is within your acceptable range, even import tax included. the antenna can be very concealed i…
  • For me the import tax is about 33 USD (1053 Taiwan dollars) 😂 https://forum.kiwisdr.com/uploads/146/U4CXHN1R5T87.jpg
  • Hi Bensay, Just visited and it seems that your high frequency band has much worse interference. I'm not an expert in this area, but in my experience trying to combat external interference the three most effective ways are grounding (plus an arrester…
  • https://forum.kiwisdr.com/index.php?p=/discussion/comment/17778#Comment_17778 my kiwiSDR 1 uses Debian 8.5 and it operates very well. No idea about the advantages for upgrading this OS version ... 😅 https://forum.kiwisdr.com/uploads/074/AWUTN3OCR2…
  • Dear jks guru, All good things will come as promised, thank you. 😄
  • https://forum.kiwisdr.com/index.php?p=/discussion/comment/16936#Comment_16936 I see. Thanks a lot for the explanation. 😀 (... It can only work on one narrow band of frequencies and will generally only allow you to 'null' out one interference source …
  • https://forum.kiwisdr.com/index.php?p=/discussion/comment/17300#Comment_17300 what a coincidence. I have bought two of this linear PSU in which one for KIWI1 and another one ready for KIWI 2(order has been placed). DC output carries very low ripp…
  • https://forum.kiwisdr.com/index.php?p=/discussion/comment/17169#Comment_17169 Hi Steve, I have no idea about others' opinion. For me, the threshold for being willing to operate a Kiwi for free and very well for many years was thought to be much hi…
  • what a useful fact this is ~~ Apple 20W type-c is regarded to be a low cost but high efficient one, and I'm interested in pitting it against a linear PSU currently in use, for background noise in VLF/MW as comparison. 😀
  • consider yet an active noise canceller like MFJ-1026 or QRM eliminator ?? I have no relevant experience using them ..
  • hi jks Firm order for one v2 with BBG/enclosure here ! 😄 73,

  • https://forum.kiwisdr.com/uploads/390/QBGLEM8J9RJK.jpg http://jjm0311.ddns.net:8073 The picture includes a linear power supply, a pre-BPF, kiwisdR+Aluminum enclosure, and wifi hub. The fan was intendedly moved to the outside to reduce vibration.
  • As I knew regarding one mini-handhe NXP-tef6686 radio project, the initiator still adopted crowdfunding to ensure a limited inventory and smooth distribution (in China). FYI. https://forum.kiwisdr.com/uploads/714/V9ZG0FEXG5R0.jpg
  • I don't have any technical support ability, but I would definitely be the first batch of purchase participants. Btw, will the frequency range of the 2nd version change (FM/PSB/UHF) in your plan?
  • thank two guru's comments  😀 Without the RFI from atmosphere it truly became much "quiet" tonight.
  • https://forum.kiwisdr.com/index.php?p=/discussion/comment/15617#Comment_15617 Hi Martin, you are correct. The browser that I have ever used with admin to visit would ignore the masked function. This case can be closed. Then, the remaining qu…
