For what it's worth here are my thoughts on the SNR topic. My primary interest is how Kiwis perform at MF so a generic SNR doesn't help. For example a receiver could have an outboard bandpass filter (or HPF) that attenuates signals in the range of 5…

WiFi 👍️ one less potential route for common mode currents to cause interference

Has the autonotch algorithm recently changed when the control button was relocated? Currently the autonotch is noticably degrading audio quality making audio distinct "digita;l" in sound. As far as I recall previously the autonotch was muc…

Hi Martin Interesting analysis. Have you tried testing whilst DC was flowing to see if saturation of the core happens and if it reduces the effectiveness of the filters. Judging by the photo, the simple filter probably can't carry as much DC curren…

Thanks for fixing.

But I spotted a parallel convesation on the forum that had a couple of neat ideas https://forum.kiwisdr.com/index.php?p=/discussion/581/messaging-users-via-your-name-or-callsign-box#latest

Hi Benson Thanks but that is the dead email address. I tried a message but gmail returned it as "The email account that you tried to reach does not exist" Sadly no way to speak the owner.

In several situations I have found that the listed email address is dead - maybe it has changed, maybe it never worked. I find it very frustrating that it is impossible to reach out to many Kiwi operators, especially if their receiver has effectivel…

Hi I have experienced this (or very similar) and was trying to determine when it happened. As far as I can tell the problem is alleviated after I click the PB Default button. It feels that I can then reliably move the upper & lower passband edge…

Hi Martin Agreed about your apples & oranges comment. However I've just got results from a test last night that used one KiwiSDr set to decode on 2187.5kHz. Simultaneously the audio output was fed to YaDD. That meant the antenna, the RF chain an…
-
I now have some overnight tests comparing the KiwiSDr using its internal JNX decoder versus an RSPdx+YaDD external decoder. The latter generated 30-50% more decodes in an overnight run from the same off-air RF signal. Interestingly it is possible t…

Has Option 1 been removed from recent software releases?

Folks, Apologies if this is OT or if it has been thoroughly discussed in the past. It's great to see lots of expressions of interest, but I am assuming these will be from people who have not yet asked the price. So they will most likely be in riche…

Hi John thanks for accepting my comment regarding memory function. V1.639 works fine now, I also find it helpful that it stores the previous frequencies even if session is terminated and browser closed. rgds Steve

I too was surprised by the change to the frequency menu. I used to use the function to quickly flip back to frequencies I had just left without having the retype or even remember the frequency. Valuable if I had been flipping through 3 or 4 differen…

Hi John re the transient suppression TVS diodes I'm not sure which device you've selected but does 5VW refer to a 5V reverse stand-off voltage? If so isn't Z401 at risk of damage from DC inserted into the antenna socket? There have many instances wh…

Hi John thanks for sharing the front end schematic. The only bit that causes me a bit of concern is the two 100k resistors linking the "earth" on the coax feedline to the "earth" on the pcb. I think the resistors and stray capaci…
