Never heard of that one
I assume u mean the freq sliders.
Are you getting any errors when u press the connect button in the window?
Another thing to check is the specific setup in options. The sliders are configurable, you may have them unchecked.
You can try the HRD forms as well and prb get a better answer rig specific, or try your luck at emailing Rick at HRD.
73 and Good Luck.
