Bill, Mike and others,
You do realize that JA on 160 meters is restricted to using FT8 at 1908 khz? Practice has been for JA to call for DX at their allocation and listen for NA stations transmitting at 1840. Widening the bandwidth window is not very eloquent. Surely using a split VFO option with 2 slices would be more feasible. My 2 cents… 73 Jay KA9CFD From: Bill Somerville <[email protected]> Sent: October 27, 2018 10:50 To: [email protected] Subject: Re: [wsjt-devel] Flex Split Operation Setup with WSJT-X Hi Russ, why do you want to use WSJT-X split operating mode with your SDR? I thought the FlexRadio Tx bandwidth could be set as wide as the Rx bandwidth, that should obviate the need for using SPLIT since you are employing an all digital audio chain. 73 Bill G4WJS.

Does anybody have any actual knowledge about this?

Aren't slices really for different frequency ranges? Split in WSJT-X is all inside the audio band pass of one slice. It just adjusts the frequency so that the audio is always in the 1500-2000Hz offset. Split is really designed for rigs (or operators) that have harmonics on their signal (usually from incorrect audio settings). As long as you aren't hitting the ALC on your Flex your signal would be clean and split is not needed. But it should work just fine on one slice. de Mike W9MDB On Thursday, October 25, 2018, 5:55:03 PM CDT, Star Light <[email protected] <mailto:[email protected]> > wrote: Hello, I have WSJT-X (v1.9.1) set up with my Yaseu FTdx9000 to operate full (not “fake") split and it works great. WSJT-X seems to always listen on the A side and set Tx on the B side (no matter how it’s set initially) and moves the B side Tx freq around in a logical way. I’m not sure how to set up the corresponding configuration on my Flex. At present I have it set to the A slice and listening through DAX 1 on the B slice (to be “split”). It makes odd freq adjustments that don’t make sense on the A Tx slice, never changes Tx to the B slice and never moves the DAX slice choice no matter how I set it up. I don’t know what it is assuming and can’t see any way to “tell it” it’s listening on the B slice. I don’t know if it assumes that in setup or something else but seems to work best when set up this way from a simply making contacts point of view. If I set Tx and DAX audio both on the A slice (always choosing split in config), it will actually activate the B slice from time to time but never set’s DAX audio output from it, or Tx to it. So it can’t actually be using the B slice for anything. Then shortly after it activates it, it deactivates it. Flex is a drop-down option so I know WSTJ-X “knows” about it, I just know how it expects the physical radio to be set up to use it in split mode. Any advice would be appreciated! Thanks, Russ KR6W
