Hi all, I may be way off here, but maybe worth saying, three days ago
trying to track down probs with AMR, I compiled and tested everything
from master, all deps + osmo-bts-trx and osmo-trx. I ran against my
standard nitb on another box though.
osmo-bts at 75852294
osmo-trx at 2dee3e99
Everything stated up fine but phones saw no network.
So I checked the RF with an RTL-SDR and I had a very narrow band
"silent" signal in the centre of the channel until I manually set
osmotrx tx-attenuation in the vty:
phy 0
instance 0
osmotrx tx-attenuation 35
I mention it because your latest cfg attached to the ticket has
osmotrx tx-attenuation oml
which is also the default I believe, in the absence of the command in
the cfg. and it didn't work for me.
At time I just presumed it should with a newer nitb.
I only have an N210 so I can't test multi-trx :-(
