Waterfall is blank

[Super Happy George]

Hello,

So I think i now have SkyRoof 99% there, its talking to the 9700 and doing the doppler and the correct frequencies, but I noted that the waterfall display is blank, even if i key up a HT on the same frequency.

Is there anything I can check here?

Hmmm … I think the waterfall is expecting an SDR to be attached. I have an old FT-847 and use an AirSpy R2 SDR with it. But if I decided to use just the ‘847, I would have to read a little more to do that. ;)

Might check the manual on that one, Gavin.
