If you are really interested in 40M only, why on earth don't you simplify your life and get rid of the tuners, the ladderline and the BL2. Run coax from the antenna spigot on the radio to the antenna. Coil up a few turns of it at the feed point if you insist on a balun (I don't necessarily), t

If I use my XG2 as a source into the K3 and set the SSB BW to the default settings for my 2.8KHz 8-pole filter (100Hz to 2.9KHz) the signal which is S9 at its peak is still S7 at zero beat.  A 100 Hz beat note on the wrong sideband is still S3 and a 200 Hz beat is >S1. The equalizer has no effe

I think he would be better off throwing away the window line and eliminating the tuner. Cut the length of the dipole for resonance on 40M and then add a 20M dipole in parallel at the feed point. There will be some interaction, which can be lessened by orienting the dipoles at right angles to

If it's not too late I would like to add another couple of requests. 1) Add Accukey emulation so I can send CW with the K3. 2) Since the new DSP mods extends the bandwidth down to minus DC, implement phasing detection to improve the opposite sideband rejection. Even without the bandwidth ext
