Sorta remember something similar to these in the early 80's and as I understood they were nothing more than a local oscillator that would beat against the incoming signal to produce an IF that corresponded to channel-3 or 4.
We had the Rogers Cable Zenith Z-TAC system but I used a leftover Sylvania that did the same thing but used this big calculator looking wired remote with a 2-digit LED display that also went to CH-36. Back then the only one that mattered to me was CH-28 and that was MTV.
