Mmmmm.... 6 meters? I just installed a 13 kHz filter tonight specifically for 6m repeater ops.
As for filters being the same bandwidth and in the same filter slot #: Elecraft K3s Owners Manual: Page 25: For diversity receive, matched filters should be used (pg. 40). Page 40: For diversity receive, we recommend using identical crystal filter configurations for the two receivers. This will ensure that both receivers have the same characteristics when strong QRM is present. Page 82: For crystal filter installation. Page 85: Rule #1: If you plan to use a particular filter for both transmitting and receiving (main receiver), you’ll need to install it on the RF board. You can optionally install a filter of the same or similar bandwidth on the sub receiver for receive-only use. (This is recommended since it will keep the receivers identical.) While not mandatory, it would appear that matching filters between receivers is HIGHLY recommended, especially if you ever plan to employ diversity receive. I actually am putting FM filters in slot #1 of both receivers, so I can listen to 6m or 2m on either receiver... Same, same 6 kHz on slot #2... so I can listen via AM on either receiver, especially when I am listening to broadcast AM, etc. If I was a CW guy primarily, I might consider giving one of them up for a 3rd CW filter besides my 700 and 400 Hz filters in #4 and #5. 73, ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 7/20/2016 10:49 PM, Don Wilhelm wrote: > Mike, > > You technically don't have to move the filters in the KRX3, but it > just makes more sense to me to have them match. > > Yes, if you do not have the K144XV in your K3, then there is no real > sense in installing the 13kHz filter (unless you want to do AM > transmit with that filter). > > 73, > Don W3FPR > > On 7/20/2016 9:59 PM, mike wrote: >> Okay Don, just ti make sure I understand about the filters.
