would any of the USRPs together with gnuradio be suitable to serve as a
configurable cross band relais?
I sometimes have applications where we have to communicate which huge
amounts of radio systems which are not ours, which means that we either
have to give out a whole bunch of radios from us (and we don’t have so
many) or work with the radios of the other party (which is not always
A very nice thing would be a cross band relais which would transmit
whatever is received from one of the channels on the other channel.
Simplex would absolutely suffice.
I have been working my way through grc but I am not absolutely clear how
to realize the squelch/PTT logic. Of course, I don’t want the box to
xmit continuously but only if an actual signal is received. There also
has to be some lockout-logic, so the relaying only goes in one direction
at a time. Otherwise, we would have a nasty feedback :).
The creamtip would be if gnuradio would speak ETSI DMR but I also didn’t
find too much about that yet…
We plan to change to DMR somewhat soon but most partners/customers still
use analog radios…
