inspired me to use an SDR to check for BTS activity and sure enough it
does briefly transmit and then stop.
so 1800 MHz is confirmed then?
The Telnet log shows "TRX is not responding -
reinitialising the unit..." and it looks like the BTS
reboots shortly after.
it might still be some "unexpected" parameters in our OML which trigger
this kind of malfunction in the BTS stack.
I did see the photos on the Wiki ofa NanoBTS with bad
caps. Is that a
known issue?
Not that I've heard of so far.
Visually the capacitors look fine in both units.
Unfortunately the 1800MHz model has some quite serious corrosion
inside and looks like some compartments have been flooded with sea
water or something caustic.
ugh. ok.
Unless anyone has some inspiration I don't think
it's worth digging
too deeply into the Osmocom side as it's likely hardware issues.
probably, given your description.
