Heathkit GD 1190 - Need help for coil

[Freddy67]

Hello everyone

I have an assembly that I started there thirty years and I've never done the coil.
The scheme resembles the Heathkit GD 1190 and is available here.

The head is 850 uH with a capacitor of 9100 pf.
How much should - it turns in to 0.3 m / m to a diameter of 20 or 25 cm?

With my thanks and greetings

For coil diameter of 20cm about 47 windings.

For coil diameter of 25cm about 44 windings.
