Ahhh…Memories!
My first receiver of any kind, back in about ’73, was a Realistic Patrolman-6 tunable radio that I used to listen to Chesterfield, Virginia fire and EMS (Back when Channel 1 was 46.46 and Channel 2 was, I believe 46.34 mhz. EMS was also lowband, but I don’t recall the exact frequency. )
First scanner was bought for me by my dad (As was the Patrolman-6) in ’74 and was a Radio Shack 8 channel crystal controlled scanner that I used in my car. Had it for years, long gone now. Built like a tank and very sensitive, esp with the whip antenna I had on my car (A Pinto!!).
Also, as I was a member of a fire company (CFD Company 1) I had one of the old, huge, gray Motorola breadboxes that had a Quik-Call activated bell. I really loved the huge old beast. Had the best audio quality of ANY monitor I have ever owned, and could pick up any unit anywhere in the county as well as Charlottesville/Albemarle and Balto County Md on good nights!
I’ve had many other scanners and monitors over the years (Including a Plectron that stayed on 24-7 for at least a decade!) but those first three were the Ones That Started It All!
