Hi,
I thought someone might have use for this.
A small SDR and RTL2832 dongle combo for scanning frequencies if having problems with radio mics or RF interference.
I use HDSDR but there are plenty of others around that are free including some basic spectrum analysers.
The dongle connects via usb2 and antenna via sma. Inside the dongle the rtl chip can receive from 100khz to 2ghz (my version). Most do 50mhz up to 1.5ghz.
Might be good for troubleshooting RF.
