For LF I re-designed the toroids to use #3 and #15 material from Amidon.
They require a lot less turns.
I'm attaching a spreadsheet with the new toroid data in it. Hopefully it
goes through. If not, I can put it in the files section of the groups.io
page.

Hi Phil;
I find what you are doing VERY interesting. indeed. I can look and see
what the LF cores and the windings are. I may have them in my small
stock. I have one RX ensemble unbuild and 5 other RXTX ensembles not
built, and one RXTX built. I had plans to make a whole QRP gaggle of rigs
to use that I built. I am just now getting back to it.. as I had 2
strokes, right cerebral. I taught myself to walk and walk with a cane.. my
mind is clearing although dizzy still and foggy after 2 years.. I had to go
on disability. I am 67 healthy otherwise.
Let me look and see. LF interests me greatly. and there was another
individual Roger Graves, VE7VV that specialized in using the RXTX as a LF
transmitter at 160m.
I need to look up ndbs to see what their freq range is to see if I have
the torrids.
