The Tx filter for SSB, Data, and CW must be 2.7 or 2.8 kHz, so FL2 is right for your installation for TX SSB and TX CW. The 2.1 kHz filter is not used for transmit, just receive. You should be able to use all your filters for receive, just enable (for receive) all installed filters for CW, LSB, USB, and DATA.
My K3 radio doesn't have an FM or AM filter, so I can't transmit in those modes, but I can receive AM using my 2.8 kHz filter and tuning to one sideband. 73 de Dick, K6KR -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of DK5EW Sent: Wednesday, February 15, 2012 9:14 AM To: Elecraft@mailman.qth.net Subject: [Elecraft] Filter installing question Hi all, I have a small understanding problem in using filters. I installed a additional SSB filter 2.1KHz/8pol on row 3. (1. is FM and 2. is 2.7KHz). I configured new 2.1KHz filter FL3_BW and set it with number 3 to 2.10, FL3_Freq to 0.00, FL3_GN to 0db, FL3_ON to YES _What I do not understand:_ On menu FL_TX_SB is now FL2 so I TX now with FL2(2.7KHz) ? Do I have to switch there on FL3 to transmit with FL3 (2.1KHz) ? Can I switch between filters in operating ? Is it then only in RX between 2.1KHz and 2.7KHz filter ? And TX filter is always that one I configured in FLTX_SB menu ?
