13C seems dependent on tuning mode perhaps so i'm watching the matching and 90s for 13C.

#double res mode 90s seen on 12/2023:
#double res mode push up and turn black switch to right 
#looking from the floor.  (clockwise looking from floor).
#no insert
#(using 1H and 13C notch or 200MHz lowpass filter)

Vr = 20kHz

H90: 3.1 us
Hpl: 9.1 W

same on 5/2024
C90: 4.5 us
Cpl: 21.0 W

cp match at:
H: 9.1 W  (ramp 90/100)
C: 15.0 W (square)

#double res mode; use this
Li7_90: 2.00us
Li7_pl: 14.0W

#triple res mode?
Li6 switch up and to the right cw looking from floor(dbl res switch setting). 
	-triple res mode for insert however.  ie includes insert
Li6_90: 5.0us
Li6_pl: 40.0W

#must be in triple res mode for Cl35 (Larmor = 39.9 MHz)
Cl35: 4.5us
Cl35: 220W  (NOTE 300W Max)!
RF = 55.55kHz at 4.5us 90

cp match (1H -> 7Li) at (vr=20kHz):
H:   11.2W (ramp90100.100)
Li7: 7.80W (square)
cp_time = 1.0ms

19F_90: 2.6us
19F_pl: 10.0W
SR=-63574 on res c6f6 (0ppm)?
