Re: [Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

I think my problem is with fldigi. I tried using cocoaModem, and it shows audio up to 4.2 KHz when I follow Joe's technique of setting the knobs to SHIFT/WIDTH, the SHIFT to 2.20 and the WIDTH to 4.00. Sorry for the bandwidth. 73 Bill AE6JV On 5/12/16 at 3:28 PM, li...@subich.com (Joe

Re: [Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

I don't know what's going on elsewhere but with FW 5.38 and the KFL3B-FM I regularly get 4 KHz bandwidth (10 - 4000 Hz, or 200 - 4200 Hz) on the waterfall in WSJT-X or an audio spectrum analyzer (e.g., Spectran, Spectrum Lab, etc.) in either SSB (LSB/USB) or DATA (DATA A and AFSK A) modes using

Re: [Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

I was referring to SSB mode, Bill. Not sure if this extends to DATA A mode, yet, but I'll investigate. Wayne N6KR On May 12, 2016, at 1:11 PM, Bill Frantz wrote: > I guess I'm just not getting it. I am in DATA A mode with the 13KHz FM filter > automatically selected.

Re: [Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

I guess I'm just not getting it. I am in DATA A mode with the 13KHz FM filter automatically selected. Following Wayne's directions, I put the bandwidth controls into Lo/Hi mode and hold NORM to normalize the passband. I then turn the Hi knob to max (4.00 shows) and the Lo know to minimum (0.00

Re: [Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

While working in this part of the firmware, could 4K receive passband be made to work with the 13KHz FM filter as well? Thanks, Bill AE6JV On 5/12/16 at 10:03 AM, n...@elecraft.com (Wayne Burdick) wrote: The K3's SSB receive passband can be widened to as much as 4.0 kHz if you have a 6.0 kHz

[Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

Hi all, The K3's SSB receive passband can be widened to as much as 4.0 kHz if you have a 6.0 kHz crystal filter. This is useful for ESSB in particular. However, there's a minor problem with the present firmware that requires a workaround (for now). The trick is that you have to have LO/HI CUT
