Hi All,
Just finished my 30 meter QCX.? The receiver and all the menu functions work fine, but there is no power out in transmit.? I pulled L1, L2, L3, and L4, recleaned the tips, resoldered them on the board.? I then checked continuity across the pads of each inductor.? The output is -0- and the power on the drains of the power amp transistors is 200 mw.
The DC voltages at pin 3 of IC3 is 0 rx and 2.4 v tx.? The DC voltage at Q1,Q2, Q3 drains is 13.2 v rx and 1.2 v tx.? The DC voltage an the gates of those transistors is -0- rx and 2.4v tx.
Where should I go from here?
Thanks.
Jack, NI8N
