Nevermind... I figured it out.
I did the stoopidest thing I could imagine. I wound the coils for the 20meter band, and I had a 40 meter crystal in it. ![]() I must say, this little toy sings! I can't even believe how great it sounds for having 1 transistor and a couple caps. Thanks again folks. DE KC9FFX "J Shrum" wrote in message news ![]() 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? http://imagenisp.ca/jsm/Tuna.html Thanks in advance. "J Shrum" wrote in message ... 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. James Shrum - KC9FFX |
