Hi Brett - Nice looking work. You must take your time, and I'm guessing enjoy some wine as you build. :-)
Is that an amplifier or an exciter? I'm curious about the vernier dials. I've never seen them used except on a self-excited radio where the tuning is *VERY* critical. Otehrwise it would seem like a real pain to have to twist the knob so many times to go from one band to another. 73, Mark W1EOF > -----Original Message----- > From: Brett gazdzinski [mailto:[EMAIL PROTECTED] > Sent: Sunday, January 08, 2006 6:49 PM > To: 'Discussion of AM Radio' > Subject: RE: [AMRadio] coils > > If it does not need to be real small, one way to get a good coil > is to wind one out of copper tubing. > Home depot sells various types, small/thin, bigger and thicker... > I made the pi net tank coil for the pair of 4D32 rf deck out of copper > tubing, > I soldered big wire terminal lugs (the crimp on type) on the ends of the > coil and bolted it to large ceramic standoff insulators. > Here is a link to a picture: > http://wa5bxo.shacknet.nu/N2DTS/new%20coil-a.JPG > > My thanks to wa5bxo who still has my pictures up! > The wine bottle in the picture was used to wind the tubing on. > The home brew receivers are in the background... > > Brett <SNIP> -- No virus found in this outgoing message.
