Jim, One thing that will cause that problem is if the 'D' and '5' wires are interchanged - they should cross over each other (guess how I discovered that <G>)
Did you make the PC trace cut on the KX1 board? Is T2 wound correctly and installed properly? - it should look like the photos. Were the toroid leads properly stripped? The unstripped lead length is rather critical in the KXB3080, but the proper lengths are indicated in the manual. Did you place the 'A' and 'B' wires as indicated in the manual? - they are mixed on the KXB3080 board, so the wire marked A on the KXB3080 goes to the B position on the KX1 board, etc. Have you checked transmmit yet? If you get proper RF output, you can be reasonably certain that the Low Pass Filter is OK, but if you find no or low power on transmit, look at the Low Pass Filter for the problem. The LPF (and the DDS) are the only components shared by both the receiver and the transmitter. 73, Don W3FPR > -----Original Message----- > > I build KX1 sn/1519 and it worked great!
