Hi Thomas.
It is very good new.
Please let us know more information how you wins!
I mean which PLL filter, ICP and other LMS paremeters do you use or its done
by just only IQ balance correction and Laurent C1 pulse and all other by
default?
Register dump and startup sequence are attached.
Uhm, this is a register dump at what time? Originally I asked for the
dump before and after every line in the umtrx_tx_init.sh.
LO leakage was also recalibrated for different
frequencies.
How different are calibration values? I've never checked how is it
related to the PLL frequency.
For comparison, after C1 pulse is added USRP1 is
1.3/3.5 and USRP2 is
1.2/3.0 when measured at 925 MHz.
tip: Would be great if you push this to github just as you send e-mail :)
PS Sylvain is waiting for a howto to run OpenBTS with UmTRX to test his setup.
