Hi Gary

I haven't tried any waterfall adjustments, the display is a bit dark on mine and on the Grabs from G6AVK signal traces of what is visible on Speclab do produce a line though. The program may need a bit more audio in than most.
I like to use the FFT display a signal shows up as bump which can be clicked on to set the frequency and then the AFC takes over.

Hi Eddie,
 
Trying to run GMSK here but cannot see anything on the waterfall on Rx, when I go to Tx I see my mode trace in strong colours. The waterfall is black & not showing the usual noise or signal traces. I have set to the external sound card I normally use with the TS-440 on LF & MF. All OK with other software.
 
Any clues please.

Software MMVari by JE3HHT. The install comes up with a language warning (it can use Varicode Extended Japanese character set) this can be ignored.

Sound Card sample  rate 48KHz..

Reports welcome
