Heading:	NEW Morgan Notch Filters 40 & 20 Meters
Ad Message:	NEW/UNUSED Morgan Notch Filters - Morgan Systems M-445 Notch Filter, 40 meters - $55 each, shipped CONUS Complement modern transceivers with a Morgan notch filter to lessen or reduce out of band RF energy from nearby transmitters. A notch filter is the opposite of a bandpass filter: Instead of allowing a band to "pass" signals and blocking everything else, a notch filter will remove the specified band and allow everything else to pass. For example: you are operating 20m and 40m stations in close proximity. The 20m station is getting interference from the 40m station. A 20m bandpass filter can be used on the 20m station which blocks all out of band signals (everything other than 20m.) But in severe cases of interference it may not be enough. A 40m notch filter can be added to the 20m station, which will deeply block or "notch" out the 40m station entirely.

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:
