I had an Audiovox version of this. I remember buying it in the early 80's from a place called Dominion Electronics, which was around Yonge/Wellesley St, I believe. Like Active, they sold surplus electronics. Think I paid $20 for it and I had it in my workshop for many years. It worked well. It had a 40 channel CB with display in the mic handset and channel changer was on the outer shaft of the tuning knob.
