[TenTec] Tapping a Delta II for a panadaptor?

[Carl Moreschi]

My software keeps both radios on the same frequency.  It allows you to 
click on the panadapter display and have the radio instantly go there. 
And as you tune the radio, the panadapter radio will follow it.  It 
works really well this way.
