My Kiwi is almost 24/7 on air (except when I use receiving amateur antennas to transmit). A very good SDR, with excellent receiving abilities, but I am forced to use high pass 1.8 filter, to eliminate the cross modulation from the very strong MW stations (about -20db), although Perseus SDR which I also use, can manage these +60db signals without any problem, maybe because of the very sofisticated front-end it uses.
It would be nice if there were more than 4 slots, because they are very often occupied all of them, and the time-out does not function as expected, because even a slight activity from a listener (e.g. moving sliders), annulate the time counter.
Please, think if it is possible to add a software noise blanker or any noise limiter. i think it would be very useful. Some other software decoders like FSK, RTTY, CW, SSTV etc, would also be a brilliant idea, because now a listeners must use virtual audio cable and thirdy part softwares to decode them.
