It's a different environment today for simulation.
I can't run LTSpice on my ARM based Orange Pi 5 Plus like I can on the
32 processor Intel.? But I can run ngspice for circuit analysis just
fine.
But, for grins, I asked DeepSeek to give me the tuning range for the
values KD1JV was using for the ADC-40 receiver BPF in the front end.
That's reason for the order for trimmers.? Was getting different
values than the BOM (which is changing daily and the reason I don't
like doing one until the project is complete).
So, the point, no more cranking up simulation and for getting the
slide rule out for some things.? Just type in a simple question and
out comes the analysis and the values.? Try this on the AI of your choice.
Given L=12 micro Henry.? What is the resonant frequencies for C=30pF and
5pF?
For DeepSeek I'm impressed.? It shows each step.? Kids in the engineering
and the sciences don't have to do homework anymore.? Didn't try the others.
Also, I use the turns calculator for toroids on KitsAndParts.com and
compared with DeepSeek and results were slightly different, but good enough
for starting assembly.
FYI
