Hi Alan, The information is in the manual but you sometimes have to search for these things.
On page 46, the crystal filter setup page, it states that you should enter a gain of 1-2 db for the 400 Hz filter. I have a 400 Hz filter and I have entered 2 db. I searched the PDF version of the K3 manual for offset and found on page 79 that it states that all 8 pole filters have zero offset. A note to this effect should have probably been added to page 46. 73, Mike K2MK I purchased a 400Hz 8 pole (Inrad) filter and installed it in my K3 yesterday. There were no markings on the box and some obscure numbers on a small label on the side of the filter case, but there was no offset figure. The Cady book mentions that for 8 pole filters an offset is unnecessary, so I presume this is correct? It also mentions adding a small gain figure of 1 or 2, what do others normally do for a CW filter? 73, Alan.
