When I assembled my K3, I ordered the filters as FM, 2.7, 1.8, 400, and had the last slot open. For the K3S, I have (1) FM, (2) 2.8, and (2) 400’s. So I have the following questions.

My guess is that the filters would be installed in the first two or three slots as they were in my original factory built K3. > If I have a say so, would it make sense to install it as such > (O = open) > Slot 1 2 3 4 5 > Main FM 2.8 O 400 O > Sub O 2.8 O 400 O That is the way mine are done - the Sub RX has a second FM filter (I wanted the ability to use wide audio for SWLing with an Aux antenna) and the main TX has a 1500 Hz filter in slot 3 which I do not use and the 200 Hz filter in slot 5. If I were to do it again, there would be no changes except to replace the 1500 Hz filter with a 1800 or possibly a 2100 (that is my typical SSB bandwidth). The FM filter it just fine for AM - both TX and RX. 73, ... Joe, W4TV On 8/8/2015 12:59 AM, Lane wrote:
Hi, I have a K3 w/o a sub-receiver and continue to enjoy learning about the hobby, and because of that, I’d like to start learning about all the things I can do w/ a sub-receiver. So I’ve ordered the new K3S-F. Seeing as I have several weeks to rethink my order before it ships, I’d like to better understand the sub and filters. I also hear the sub is a pain to remove and wanted to get my filters right initially if possible. When I assembled my K3, I ordered the filters as FM, 2.7, 1.8, 400, and had the last slot open.

If I have a say so, would it make sense to install it as such (O = open) Slot 1 2 3 4 5 Main FM 2.8 O 400 O Sub O 2.8 O 400 O By doing that, I leave the last slot open for 200Hz filters if they come back, and slot 3 for something between 2.1 and above 400 if I can find a good reason to fill them. My understanding of diversity reception is that I can receive two different frequencies and though used more for CW when working pile-ups, it’s not something I’d likely use for FM, hence the single FM roofing filter. So I was wondering about installing AM on the sub just so that I could have that as well. I'd be interested in knowing how you guys did it.
