Re: RTL-SDR v3 direct sampling over a network

I've duplicated your setup with a Pi and V3 dongle using the rtl_tcp -a xxx xxx xxx xx -D 2. I'm listening to the 20M band at the moment and its working...Using SDR #....

Re: Shift in Frequency Display

AZDT, perhaps things are a little backwards in your entry. 148.MHZ is 2m Band.
173 is outside the ham bands...

Re: plutosdr

You need to use an older version of sharp...I'm running 1583.....ALSO has to be a 32 bit version of sharp.

Re: Dropped samples

-d is not a ser # .....even if you've reprogrammed the ser # of each new dongle
The # that's listed on the left when you do a rtL_test is the -d #.

Re: rtl sdr v3 bias tee driver not working

If you have rtl_biast then you probably have rtl_eeprom -s ....you can change the ser# of the dongle. Help you figure out which is -d 0 -d 1 ..

Plug it into an active usb hub.
I've seen this a few times...always the fix
