rx.linkfanel.net receiver map moving to Leaflet
Relative to that topic, is there any how-to, guide or documentation anywhere to improving and tuning reception quality on your KiwiSDR?
I do not think there is anything in one spot. There are many excellent posts here in this forum. Here's a summary of my experiences:- Have a reasonably good antenna and keep it away from known RFI sources.
- Be conscious of things like MW BC overload and apply filters as required
- Avoid switching PSU, some are quiet but most are not so try to use linear PSU
- Understand Common Mode Interference, read up on it, applies the easy remedies like use of ferrite core and intermediate grounding on your feedline
- Watch for spurious using the [SPEC] display on a KiwiSDR client webpage, much noise can be noted by "lumps" of noise or spurs carriers at repeating spacing across a band
- ID noise spurious by turning things on/off within your dwelling ot near the antenna
- a partial list...
- Have a reasonably good antenna and keep it away from known RFI sources.

DRM Heard
Marti DRM loud here in NY this afternoon
Update: after noting that they were running 9 KHz BW, I pulled the corners of the passband in a tad and got an SNR improvement. China Radio Int'l sits right on the top corner of the 10 KHz passband

DRM forces BW [fixed in v1.385]
adaptive would be great but just allowing the DX label PB value to force the BW rather than DRM forcing it would suffice

antenna system tool
I bought one of the ~$50 NanoVNA and a great little device for testing and aligning coax, filters etc. Here's a shot of my notch filter box using it. NanoVNA-H is the thing to buy, see Google
