MR. ED asked:
I have a wireless fish finder sonar that operates at wireless frequency of 433 mHz. Well the sonar was damaged. I found a replacement but the replacement operates at 433.9 mHz. Now i don't know anything about mHz. I wanted to know if i buy the sonar that operates at 433mHz will it work with my receiver which operaes at 433.9 mHz. Thanks to anyone who can answer this question.
