FT8 audio not decoded with recommended FT-891 settings

I just installed my DR-891. It took me a little back and forth before I was able to get the radio to actually transmit power. Now transmit works perfectly, but my FT-891 switches tog D-U mode and in that mode I only hear a crackling sound and WSJTX isn’t able to decode anything. If I manually switch my radio back to SSB, I hear the FT8 sound and WSJTX is properly decoding the audio.

Until I Enable TX again - radio transmits, I can see myself popping up on PSK-reporter, but radio switches back to D-U and is unable to decode.

Is there a way to set up split mode, so that the radio transmit in D-U mode, but receives in SSB?

set split to none in wsjt-x

fake it might work but try setting it to none just to get something going.

split is absolutely NOT required.
using split will change your tx freq so that whatever ‘spot’ on the waterfall you’ve chosen to tx on, it will be in the ‘sweet spot’ of audio response.
the sweet spot is actually pretty generous and will only make a difference on extreme ‘spreads’ of rx vs tx ‘spot on the waterfall’

good luck

Hi webmonkey,

Thanks for your reply. The issue is not related to a frequency split. My radio switches to DATA mode once the settings work. In order to have my radio transmit I need to set the mode to Data/Pkt in WSJT-X. Using that mode works fine for TX. But in RX the audio can’t be decoded by WSJT-X when the mode is DATA. I have to manually set it back to SSB. This seems to be an issue with WSJT-X, but not sure how to fix it, because I have tried both current V2.7 and the new 3.0RC1 on both Windows and Mac.
Are there any FT-891 users here who have the same problem?

I also tried the iFTX app on my iPad. It’s very rudimentary, but it works perfectly with DigiRig and the FT-891, with both RX and TX set to SSB.

gotcha, you had stated that it was in the correct mode until you enabled tx.
it made me think that upon tx, wsjt-x was issuing not only a freq change but polling the mode and switching to data/pkt (your radio = D - U)

i guessed you had already set MODE, in wsjt-x to NONE.
this makes sure wsjt-x does not issue cat commands pertaining to the radio mode and leaves it in whatever mode you have it set to.

good luck

You’ll need to open the filter.

Finally, use the short presses of the “F” button and MULTI knob to access the “WDH” option to open the bandwidth to full 3000Hz.
