A tuning cap and trying some diodes, surprised to hear many shortwave bc stations.

Back ...The "Lyonodyne" set caught my eye. Back in the '80's, I made a similar set that used coils wound on ferrite rods instead of the air coils shown. You could vary the amount of coupling by the spacing of the rods in parallel with each other, as shown in the pic. I see that the outer coupled coils are wave traps. Also see the constructor using a ferrite rod/coil for air coupling pickup to the middle main coil.<br /><br />I was amazed at the selectivity and audio quality from a properly performing/designed xtal set. Back in the 60's BCB dx'ing was fun. I gave up on it awhile back because of the way that gov/business has taken over the content allowed on stations. Nothing worthwhile to listen to anymore. The hobby was fun while it lasted.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3380839830287420877.post-10685885699282195222021-10-25T11:10:58.536-07:002021-10-25T11:10:58.536-07:00Great entry.
