Do you read the manual?
Are there any information on the net?

SDR# can Track it on AM.

in my case i could only receive anything beside of Radio when I use an LNA.

I talk about +30mhz. Sorry its insane to use an Discone Antenna (wo have ~ 0dm gain) on a dongle without an LNA!
He use an cheap and crappy dongle not the fancy net "optimized one".

First start with an Blade Server System and an Hyper visor of you choise. You get an used Blade Server system for 10 - 20 Tsnd €. Ok the SDR Dongle are not that complicated you need (depend how much channel you need to decode) 5 - 20€ it cost <500€ And than you could run GNU Radio on your Bladeserve...

the dingles are quite DEATH!
Without an LNA the are quite useless. You get Strom Radio/ TV Stations and maybe the local AFU Repeater and that it was.

Yes, usually the first dongle plugged in will be -d 0, the second -d 1 etc.

WTF?!
Now I have 4 Dongle in use with different Setups and Filter!!! Later I will use 30 - 40 !!!!

First i will start with VHF/ UHF.
sshhttt you are right he forgott 3x 000

like: .exe -d 12345 ???

Its possible to set an freq correction on the server so when i switch between the dongle i dont have to edit?
(like -ppm -40 ?!

Calibrate to what? What I am I correcting the frequency to? an Weather Channel or any other Static Channel who get professional equitment. You put the RF Gain to the right side and select Offset Tuning, RTL AGC ? You cant see anything because the Antenna have no Gain and the Dongle also have no Gai...
