60m UK bandplan

I frequently operate digital modes JT65 and JT9, using WSJT-X with my 6500.  Looking at the RSGB’s bandplan it states that: “If the radio is set to 5357.0kHz, any transmission greater than 1000Hz (1kHz) on the waterfall will be above 5358.0kHz and therefore out of band. This will occur with JT65 and JT9 modes if the default frequency is left at 5357kHz, so be very aware of where the transmitted signal lies.”

If I use WSJT-X to set the frequency as 5.357MHz and then set the transmit frequency so I am safely within the 1KHz allowed, SSDR won’t let me transmit unless I adjust the High Cut frequency to 1KHz in the Phone tab.  Otherwise the Tune, MOX, ATU, MEM buttons are all greyed out, presumably as the TURF file thinks I’d be transmitting out of the UK band allocation. 

Scrolling across the band it seems – in theory – I could transmit on frequencies we have not been allocated (as per the bandplan) but not on others where we are allowed.

Have I misunderstood something here or is there another TURF file appropriate for the UK?  Under ‘Radio’ in the radio setup menu it shows the region as EU02. If I do require a new TURF file will this come from the UK distributor from whom I bought the radio, from Klaus in Germany or directly from Flex?

Jeff, you have the correct TURF file.  I suspect you are transmitting out of band as per the community post that Steve referenced above.

Thanks both for the clarification.  Bottom line:  with the 'VFO' set at 5.357MHz we can only operate JT9/JT65 such that the transmission doesn't go higher than 5.358MHz.  I thought the TURF file avoided this but clearly it doesn't.

The TURF file enforces keeping emissions inside the designated frequency range by using both the Slice frequency and the bandwidth of the TX filter.

That makes sense, but if I set the TX filter (High Cut) to 1KHz and the slice frequency to 5.357MHz and JT65's frequency to, say, 990Hz I can still transmit (in this case it would be out of band).  If the TURF file enforces the limit of emissions, why am I able to do this?
