Re: Seeing spectrum of UHF (HDTV) Broadcast Band

I don't believe anyone has created a Spectrum Analysis app for the Mirics chip set..
I use Spektrum and touchstone with the RTL dongle and Spectrum Spy with the Airspy...
the actual bandwidth of the device is of no concern if it can be stepped/scanned fast enough..

Re: No HF receive for 2-months now?????

it is a shame the SDRplay team have to be polite.
It would have been nice if you revealed the OS and app you were using.. Only HDSDR and open source SDR# use EXTIO.

Re: Nothing But Noise on SDRUno

Well I had a simular problem.. but it was nice music..
check to be sure you only have 1 VRX open..

on the main page you should have just one line:
0 sp1 sp2 rx green
not
0 sp1 sp2 rx green
1 sp1 sp2 rx green

ur vrx 0 is on noise and vrx1 might have the command focus.

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.. Its a rare system that lets you get to 10msp without loss (audio drop out). thats 60 - 120 mill...

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?
