"Starting with version 1.1, WSJT-X offers displayed bandwidths as large as 5 kHz and provides dual-mode reception. If your receiver can provide at least 4 kHz bandwidth in USB mode, you can set your dial frequency to one of the standard JT65 frequencies — for example, 14.076 MHz for 20 meters — and have the full JT65 and JT9 sub-bands displayed simultaneously on the waterfall. You can make QSOs in both modes using nothing more than mouse clicks."
" Note that most SSB transceivers have a fixed Tx filter that will not pass audio frequencies higher than about 2700 Hz. WSJT-X v1.1 takes care of this by using Split mode, receiving with VFO A and transmitting with VFO B. The Tx dial frequency (VFO B) is offset in 1000 Hz steps, and the generated audio frequency is adjusted so that it always falls in the range 1000 – 2000 Hz. With CAT and Split Tx enabled on the configuration screen and your transceiver set to Split mode, frequency control will be handled automatically " On Mon, Jan 20, 2014 at 7:49 AM, Andrew O'Brien <[email protected]> wrote: > I thought that it was the RECEIVE filter that WSJT-X wants set to 4 Khz. ? > Andy K3UK > > > On Mon, Jan 20, 2014 at 7:25 AM, Tim Ellison <[email protected]>wrote: > >> The 1500 has a max tx filter upper limit of 3850 Hz.
