Back to main Back to RadioShack/Realistic Next receiver/scanner Last modified 2023-08-31 No Pro-78 found despite extended research! Many seem to confuse this one with the Pro-7B. Yes, it's a B, not an 8. You can also look closely at the label on the rear and check the cat. no. It will most likely say 20-173, which consequently is the Pro-7B and NOT a Pro-78. Maybe a pair of glasses would help?
