I am trying to make the Micronaut. I have put it together manhattan style
(which I find soooo much easier). I have tried using the air core and a
toroid I had...
The trouble is at this point, is the thing won't oscillate. The only
substitues I made was, instead of a 2n2222, i used a 2n3904... I also had to
use 220pF caps instead of 270pF's for C1,C2 and C3.

I have checked w/ a freq counter, and I see no oscillation coming of of any
test points.

Has anyone made this?

Thanks in advance.

Greetings,
As a newbie to RF building, I have noticed that some instructions tell you
how to wind the coil, and they give you the value of the coild as well...

In my scenario, the inductor in question is a .72uhy which the directions
state to use 17 turns of #30 around a toroid. I don't have the requested
toroid, so I was just going to wind a .72uhy inductor around a 1/2W 5M ohm
resistor.

This will just the same right? Whether its a .72 on a toroid, or a .72 on

a
resistor... they are both the same, correct?

Thanks for your help.
