For a quick sanity check I use rtl_fm to tune into a local FM
station. Here is a good guide for rtl_fm:
Hello!
I received my USB-DVB-T+DAB+FM dongle last week, and
have been trying to find a signal with it since, but with no
luck. Can anyone tell me how to tell if it is working at
all?
I'm using the Windows version of Osmocom under WinXP.
Using rtl_eeprom, I get the following display:
--------------------------
Vendor ID 0x0bda
Product ID 0x2838
Manufacturer Realtek
Product RTL2838UHIDIR
Serial Number 00000000001
Serial Number Enabled Yes
IR Endpoint Enabled Yes
Remote Wakeup Enabled No
-----------------------
When I run
rtl_test -s 1.6e6
I get the following response:
-----------------------
Found 1 device(s)
0: ezcap USB 2.0 DVB-T/DAB/FM dongle
Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle
Supported gain values(29): 0.0 0.9 .... 49.6
Info: This tool will continuously read from the device,
and report if samples get lost.
If you observer no further output, everything is fine.
Reading samples in async mode...
--------------------------
If at that point after a while I press Control C, I get
---------------------------
Signal caught, exiting!
---------------------------
But then my command prompt window hangs up and will do
nothing until I close it all together.
Does it appear that my dongle is working? Where do I
find out how to use the different gains that are listed by
rtl_test? Could my difficulties have anything to do with
the fact that my dongle is IR Endpoint enabled?
I am brand new to this, and haven't had much luck so
far, although I think I've gotten further with Osmocom and
Windows than with anything else I've tried. Any
help/advice/links to more information will be much
appreciated. Sorry for the long post -- I was trying to
provide as much information as I could.
Thanks
