Is this as far as we got with this stuff? Are we happy with these choices of frequency or is more analysis/thought needed? There are other things to do too, but if there is lead time with some modifications/parts it may make sense to get going on it so we are ready to go at some later point.
That is perfectly in agreement with my analysis.
36MHz and 37MHz are good according with our analysis if 1MHz separation between the two modulation frequencies is good enough;
If 1MHz separation is not enough than we should consider 34.5MHz and 37MHz. Here the risk is to get close to the order 23 (n+m) at
a nominal detuning frequency that is around 2.2MHz.
