Just be aware that current DSP firmware in the K3 limits the receive bandwidth to something around 3400 Hz. So even if you have a wider filter, like the 6 KHz AM filter, you will not be able to utilize the full 4 KHz bandwidth of WSJT-X for JT65/MT9 modes.
Absolutely *not* true ... I regularly receive 200 to 2400 Hz in DATA A with the FM (or AM) filter. It is simply a matter of adjusting the High and Low cut frequencies to 200/4200 or shift/Width to 2200/4000. I have been doing that ever since K1JT offered me a pre-release look at the "wideband" decoding support in WSJT-X with no issues other than some CAT problems with the interface to CI-V Commander from DXLab Suite which K1JT and AA6YQ resolved quite quickly. 73, ...

Lyle is aware of this issue and it is on his list to work on in the future. And even if you are in Split mode, rest assured that you know exactly where you are transmitting -- on the exact audio offset indicated on the display. Operating Split is the way to go. The only drawback I've seen is that WSJT-X does nothing to make sure the K3 is in the Split mode, it just assumes it is. 73, Bob, WB4SON ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
