[TenTec] 160 Meter Problem

[Mike Bryce]

jim,

pop the covers

remove and then plug back in connectors 82 and 83 on the 81595 board (mixer)

remove and then plug back in connector 82 on the logic board

with your vom measure voltage on connector 82 on the 81595 mixer and connector 82 on the logic board.

I can’t tell you what pin, but a guess at looking at the schematic on connector 82 on the logic board the 160 meter band is the pin closest to the left of the connector as you look down with the tab on the rear.

as you step through the bands, you’ll see a pin go high. change bands and that pin will go low and the next one high.
