Still interested in any comments about how the KX3 noise blanker is implemented, and if it could be improved to make it as effective as the wide band RF blanker in HDSDR.
I now have the SDRPlay tracking the KX3 VFO so that in the event of static rain QRN I can switch to the SDRPlay for good copy when the KX3 is useless. 73 from David GM4JJJ > On 9 Dec 2015, at 20:30, <gm4...@yahoo.co.uk> <gm4...@yahoo.co.uk> wrote: > > I use my KX3 on 144 MHz (with external transverter). > > Comments regarding the KX3 Noise blanker: > > It is effective for some kinds of power line noise and ignition noise, I > normally leave it on at a setting of 6. > > It is not effective at all with heavy rain or snow static. > > By way of comparison I have an SDRPlay dongle connected to the same > transverter and using the HDSDR software can enable the RF noise blanker in > that software and it can reduce an S9+20 rain static noise that masks all > signals to almost zero and allows me to decode a distant weak CW beacon that > is just above the noise floor.
