Greetings,

?

I have an issue with the Perseus with FLDigi an BlackCat WEFAX (the only two decoders that I have.

?

Note the vertical interference marks showing on both decoders.? However on the Perseus, there is not such interference shown in the spectrum nor the waterfall view. Both picture attached to show the Perseus is not showing the interference

?

When I use my RSPdx and HF+ Discovery, this situation does NOT occur.? I am using the same antenna for all three radios.? I have tried the Perseus/decoders set with a VAC and also the signal to the PC speakers.

?

Does anyone have any possible ideas what might be causing the vertical interference lines?

?

By the way, I have tried powering the Perseus with a PSU from Jameco and with a USB cable.

?

One more thing:? I can not get the brightness and the other slide switches to work on the right-hand side next to the spectrum/waterfall screen.? I have never notices an issue before.

?

Regards,

George
