I'll disagree with you on that Phil, I recently built 5 coils
using 6" polystyrene pipe coupler as a form. I wound them with 660/46
wire with spacing's of 11 Turns Per Inch, 12 TPI, 13 TPI, 14 TPI and 15
TPI. All coils were between 232uh and 237uh.
10 TPI, 11 TPI and 12 TPI were pretty close, with Q at 500kHz of 1250,
peaking at about 750kHz with a Q of 1450 and dropping to 950 at 1600kHz.
I used a Boonton 260A Q meter and averaged 5 tests, I'll give the
caveat that high Q's are elusive to measure.
Your standard 61 material is to lossy to get this high, there is some
lower loss material coming out of China that is performing well. The
best I ever got with a #61 material was 550 Q.
Now to defeat my argument, a Chinese radio amateur made a rod with 26
toroids with a Teflon core and Teflon spacers and two parallel 660/46
litz wires, measured peak Q just over 1812.
Then another another duplicated his experiment and got peak Q of 2026.
The material is coming from China and is R40C1.
