The osmocom $sourk block:
While primarily being developed for the OsmoSDR hardware, this block as well supports:
#if $sourk == 'source':
* FUNcube Dongle through libgnuradio-fcd
* FUNcube Dongle Pro+ through gr-fcdproplus
* sysmocom OsmoSDR Devices through libosmosdr
* RTL2832U based DVB-T dongles through librtlsdr
* RTL-TCP spectrum server (see librtlsdr project)
* MSi2500 based DVB-T dongles through libmirisdr
* SDRplay RSP devices through SDRplay library
* gnuradio .cfile input through libgnuradio-blocks
* RFSPACE SDR-IQ, SDR-IP, NetSDR (incl. X2 option)
* AirSpy Wideband Receiver through libairspy
#end if
#if $sourk == 'sink':
* gnuradio .cfile output through libgnuradio-blocks
#end if
* CCCamp 2015 rad1o Badge through libhackrf
* Great Scott Gadgets HackRF through libhackrf
* Nuand LLC bladeRF through libbladeRF library
* Ettus USRP Devices through Ettus UHD library
* Fairwaves UmTRX through Fairwaves' fork of UHD
* Red Pitaya SDR transceiver (http://bazaar.redpitaya.com)
* FreeSRP through libfreesrp library
By using the osmocom $sourk block you can take advantage of a common software api in your application(s) independent of the underlying radio hardware.
Output Type:
This parameter controls the data type of the stream in gnuradio. Only complex float32 samples are supported at the moment.
Device Arguments:
The device argument is a comma delimited string used to locate devices on your system. Device arguments for multiple devices may be given by separating them with a space.
Use the device id or name/serial (if applicable) to specify a certain device or list of devices. If left blank, the first device found will be used.
Examples:
Optional arguments are placed into [] brackets, remove the brackets before using them! Specific variable values are separated with a |, choose one of them. Variable values containing spaces shall be enclosed in '' as demonstrated in examples section below.
Lines ending with ... mean it's possible to bind devices together by specifying multiple device arguments separated with a space.

Num Channels:
Selects the total number of channels in this multi-device configuration. Required when specifying multiple device arguments.
Sample Rate:
The sample rate is the number of samples per second output by this block on each channel.
Frequency:
The center frequency is the frequency the RF chain is tuned to.
Freq. Corr.:
The frequency correction factor in parts per million (ppm). Set to 0 if unknown.
#if $sourk == 'source':
DC Offset Mode:
Controls the behavior of hardware DC offset corrrection.
Off: Disable correction algorithm (pass through).
Manual: Keep last estimated correction when switched from Automatic to Manual.
Automatic: Periodicallly find the best solution to compensate for DC offset.
This functionality is available for USRP devices only.
IQ Balance Mode:
Controls the behavior of software IQ imbalance corrrection.
Off: Disable correction algorithm (pass through).
Manual: Keep last estimated correction when switched from Automatic to Manual.
Automatic: Periodicallly find the best solution to compensate for image signals.
This functionality depends on http://cgit.osmocom.org/cgit/gr-iqbal/
Gain Mode:
Chooses between the manual (default) and automatic gain mode where appropriate.
To allow manual control of RF/IF/BB gain stages, manual gain mode must be configured.
Currently, only RTL-SDR devices support automatic gain mode.
#end if
RF Gain:
Overall RF gain of the device.
IF Gain:
Overall intermediate frequency gain of the device.
This setting is available for RTL-SDR and OsmoSDR devices with E4000 tuners and HackRF in receive and transmit mode. Observations lead to a reasonable gain range from 15 to 30dB.
BB Gain:
Overall baseband gain of the device.
This setting is available for HackRF in receive mode. Observations lead to a reasonable gain range from 15 to 30dB.
Antenna:
For devices with only one antenna, this may be left blank.
Otherwise, the user should specify one of the possible antenna choices.
Bandwidth:
Set the bandpass filter on the radio frontend. To use the default (automatic) bandwidth filter setting, this should be zero.
