10.9 MHz IF?
Thank you for your responses. These filters were definitely from the very
early 70s or maybe mid- or late 70s. The guy who sold them to me at the swap
meet mentioned that they may have come out of a Cubic or Astro rig of that
era, but he wasn't sure and I just wondered if there was anybody here who
might be sure of that.
Thanks again, you guys.
