I concur with Don and others (although I don't find tuning with the 1.8 kHz too hard), it really does help me to hear a DX, especially on lower bands where I have a S7+ noise floor (urban environment).
I generally tune with the 2.8 kHz and then drop in the 1.8KHz in using the II filter setting. When setting the width to use the 1.8 kHz, it's best to use High/Low, rather than Width and reduce the high and increase the low until you drop down to the 1.8 kHz filter, this gives better audio and readability than just changing the width around the centre frequency - the final setting tending to be offset. BTW, if you are getting the 2nd receiver, getting the 2.8 kHz filter means you don't need to match a pair of 2.7 kHz filters, just get another 2.8 kHz for the KRX3. 73 de David, M0XDF (K3 #174, P3 #108) -- Whales have calves, Cats have kittens, Bears have cubs, Bats have bittens, Swans have cygnets, Seals have puppies, But guppies just have little guppies. - Ogden Nash (1902-1971) On 14 Jan 2012, at 04:29, Don Wilhelm wrote: > Keith, > > Under what conditions do you use the 2.1 kHz filter and wish for the > 1.8?
