[AMMRL] No Na23 Tune dip on 500 MHz BBFO probe (Neo500)

We are trying to tune Na23 for the first time on the Neo500 with a room temp
BBFO probe. I tried ATMA which indicated that I should first try the
optimization algorithm using ATMM. I'm seeing absolutely no sign of a dip.

I've tried with no sample and with NaCl solution.

I assume that Na23 should be readily available in a standard broadband probe?

The Neo500 HPPR2 doesn't have any filters as far as I can tell.
