Re: EUROSTICK DX 25-2000MHz - Small amount of FM channels ONLY

Have you been increasing the RF gain? Or is it still at the default of zero?

Re: DMR/DIGITAL FREQUENCIES

Upload a screenshot showing all your settings, and what the waterfall & spectrum looks like when tuned to a known frequency.

Re: Power saving mode?

This is something you could implement by making modification to the RTL-SDR driver code. Have a look at the Osmocom drivers and the r82xx_standby function, or also in the Airspy R2 drivers for the R820T2 registers to set for sleep mode.

Re: Automatic Syncing Script

Excellent, thanks for the very nice work! I'll pin this to the top in case others want to try it.

In an advanced future version of the code we're hoping to have everything fully automated. It should be ready before the end of the year.

Re: Kerberos SDR stopped responding

If another unit is working fine, then it seems like a hardware issue. Can you run rtl_test on the four tuners on the system (or use the DIP switch to isolate), and see if all tuners are working?

Re: Range-Doppler Map Units and ATSC signal

Not sure of the texts, but you could start by Googling "bistatic radar" or "bistatic range", or "bistatic doppler shift". Tamas' thesis would be a good reference but unfortunately it's on written in Hungarian. Not sure if a machine translation would be useful https://www.tamaspeto.com/tpeto-publicat...

Re: Help getting KerberosSDR to work

What is your antenna array like, and are you actually tuned to a signal? If it's just random noise being received then the directions will show randomly.

Re: SDR# and DSDplus Decoding issues

Appears to be a data only channel, try a different channel.

Re: Hackrf with SDR SHarp Radio

Do you have an antenna plugged in, and have you played with the gain settings?

Re: Need to roll-back

It should go back if you use the Windows replace driver interface.

Device Manager -> Update Driver-> Browse Computer for drivers -> Let me pick from a list

There is should show your previous driver which you can select and use.
