Hi Matt

Glad to know it was all safe re input levels.

The problem with the not locking to 5G is very intermittent. A few times
when it did occur, I tried your suggestion of trying 5G a second time:

2 out of 3 times, it locked the second time. The other time, it did not,
but then trying 2.35G followed by 5G did then work.

Regarding the other intermittent issue that appeared as IQ imbalance, I
have swapped the USRP2/XCVR2450 pair used for transmit with the receive
one, and haven't observed the issue since. It may still occasionally
occur for the first pair, but this is a workaround for me. I am still
confused as to why it occurred to begin with.

Best Regards

Ian.
