Hi Wes, What DC voltage do you read at pins 1 and 7 to circuit ground? The voltage should be about 2.5 volts DC.
Also, with a jumper plug on JP2 to select one of the crystals, and a jumper plug on JP1 to set division by 4, (4x position), do you see the 40m quadrature clock signals at pins 2 and 14 of U7? If you do not have a scope, measure the DC voltage at these two pin to circuit ground. The DC voltage should be about 2.5 volts if the quadrature clocks are running. (This only says that some 50% duty cycle clock is running, not necessarily the right frequency.) 73, Tony KB9YIG ----- Original Message ----- From: Wes Hartman To: [email protected] Sent: Wednesday, May 28, 2008 9:40 PM Subject: [softrock40] Re: No output from RXTX 6.2 40/80 Thanks, Tony. Indeed there was a short on the 5v bus. I had U6 inverted, must've gotten excited that I was almost through with construction. After pulling U6 and reinstalling it correctly, the short corrected. I am now getting correct voltage and current measurements from the 2 test points. I also took note of the line input from another post about frying U8 and installed 3pin headers for the line in and out ports. I get no signal from the board, it seems deaf. Can somebody point me in another direction or have I completely borked this? :) Thanks in advance, -Wes, KC5FGK
