455Kc crystal filter
I also recall a test set in the early days that had a crystal
oscillator that generated a test signal at IF frequencies ,like 455, 10.7 etc using plugin xtals..W4PQW Ed wrote: Please educate me. I see one of these for sale on ebay that plugs into a crystal socket. I know that a lot of boatanchor IF's are 455Kc, does this generate the IF for old receivers, or is it a bandpass filter? |
