[Lowfer] Hex loop calculator

[wa3tts at verizon.net]

Hi J.B. & All:  There is an interesting loop calculator at https://miguelvaca.github.io/vk3cpu/magloop.html  which has a hexagonal option. 
The blue slider bars adjust the calculator variables and the loop type buttons are along the bottom of the control panel area  I maxed out the loop inductance and the dynamic plot chart showed its performance from about 150 kHz to 2 MHz.   So you could upscale this by a factor of 10 on the variables to get something representative of the 15kHz to 200 kHz range.  As a check do a divide by 10 scaling and check against what the calculator predicts.
LOL, just pretend your have an x10 button on you display screen like the one on your scope probe.  Yes you have to keep track of which way each varable changes but it is still infinitely faster than longhand derivations from Maxwell's Equations.  Pretty neat calculator, my congrats to VK3CPU.   I wish I had the time to play with this for a few hours....back to the salt mine here.

I can’t find an online calculator for a hexagonal, multi-turn receiving loop.
If anybody can point me to one, I’d really appreciate it.  The antenna is
for VLF reception and it will have twenty turns on a wooden hex frame
with a maximum dimension of 40 inches across.  That’s as big as I can
manage, which will fit into my SUV’s cargo area!
