Hi folks,
I've been messing around with rtl_tcp and an RTL2832 device on a Raspberry Pi
and want to add a bank of front end filters and a LNA that can be controlled by
the GPIO.
I want to allow manual control of the signal path via a web page hosted on the
Pi, but also want to be able to have the filters selected automatically based
on the frequency that the RTL device is tuned to.
I noticed that rtl_tcp helpfully echos the frequency changes to the console, so
I wrote a simple shell script to gather this data and control the GPIO.
Somebody may have already done this and there is probably a better way to
achieve it but, if this would be of any use to you, please feel free to copy
and use as you wish.

Great job!
I wrote an external program to control gpio, i'll try to implement your
solution!
Many thanks!
