Your Response to this Ad:

Due to the amount of non-ham scammers trying to respond to the ads, I am now asking a simple question that ham operators should easily be able to answer, but scammers may not know the answer: What is the number that hams use to represent the phrase "Best Regards"? This number is typically transmitted by hams at the end of a QSO.
Best Regards:
