# eroyee; experimental module for soapyMiri driver that should run Mirics-based hardware.
|
|
#
|
|
# Library / driver is from Erik here : https://github.com/ericek111/SoapyMiri, and
|
|
# Edouard here: https://github.com/f4exb/libmirisdr-4
|
|
#
|
|
# This is quite alpha, I've tested it with just one device which seems to work,
|
|
# but there may be some spurious signals, and in some cases it won't receive
|
|
# dead on the centre frequency. This should be addressable by setting an offset.
|
|
#
|
|
# Help to improve this is welcome, and there may be other settings to implement
|
|
# in time, just not yet.
|
|
#
|
|
# Sampling rate should be set at specified values such as 2, 5, 8 MHz, other rates
|
|
# can give errors.
|
|
#
|
|
# If present you will need to blacklist the msi2500 device drivers.
|
|
# See : https://www.radiosrs.net/msi2500_driver_conflicts.html
