    Roofing filter question

    Just weighing my options here. Lets talk about SSB atm. If I have a 2.8 filter and a 1.8 filter, is there really a need for a 2.1 filter? 2.8 (normally what I run for ssb ragchew, well 2.7-3 depending on the rigs I have owned) will work just fine for SSB ragchew. I would venture to say that 2.1 and 1.8 are more often than not both used for DX and or contesting in a crowded band.

    The difference in bandwidth does not seem all that large. I guess what I am wondering is, is there a significant difference between the two and what is the advantage to having one over the other, if any?

    That being said, most rigs that I have owned have only ever had 1 filter for SSB. Be it 2.4, 2.5, 2.7, or 3.

    Why do I ask? Well, for quite some time now I have been working out how I want to order my K3 when I get back state side.

    I have decided that the filter lineup will be
    6 (still on the fence about this as I dont intend to use the rig for AM but I do a bit of ESSB here and there)
    2.8 swap
    2.1 and or 1.8 but am unsure
    250hz

    Now that we are at it, I will mention other things that I am for, against, or on the fence about. Suggestions one way or the other are welcome.

    For
    P3
    KAT3 (ATU)
    KT3XCO3-1 (TCXO)
    KXV3A (RX AT, IF out, XVERT)

    Against
    13k fliter
    2m Module
    KDVR3

    On the fence
    P3SVGA (Video Adapter)
    KRX3 (SUB RX)
    KBPF3 (Gen Cov)

    Okay, so the filter question would be great to have answered. Suggestions otherwise are just gravy. Now, I know that the Sub RX does have its advantages but I am just not sure that I will use it enough to justify the extra cost of both it and the filters to compliment it. I have had very few radios in the past with a Sub RX and those that did have, I never used the option. Many say its better to be safe than sorry, idk.

    Again, opinions welcome.

    (PS: SSB/CW use only. I will not use AM nor digi modes. Mostly Ragchew with occasional DX and contesting.)

    Thank you for your time and suggestions.

    Sorry, cant change the title to say K3 questions...Initially the post was only about the roofing filter, lol.
