Re: Nothing But Noise on SDRUno

Well I had a simular problem.. but it was nice music..

Re: Audio cuts in and out

what we need here is a raw thru-put test app like what airspy tools provides for Airspy but for Mirics chips. lots of USB 2.0 pipes are dropping bits by the time we get to 5 (million samples/second) msp..

Re: Different Band on each receiver

Well, that is just 1.8 - 7.4 mhz so if the first rx was on the 80, with a 8mhz bw the vrx's could land on 160 and 40 mtr chunks. Yes?

Re: Different Band on each receiver

Re: SDRUno V1.1 Cookbook

Ah, me thinks the BW on the EXTio is no longer restricted to 96000? Maybe my AirSpy will now be able to start up at its slowest and of course the RTL's at their widest.
