Re: Problem winding T501 on a QMX+


 

Are the BS170's installed?? I assume they are not blown if you have not yet finished building the transmitter part of the board, but there could be a solder glob from drain to ground somewhere.
Is L502 installed?? Could be a short to ground on the far side of L502.

I checked the test points called out on page 27 for checking for no short at any of the points marked "A".? I'm finding the center tap point of T501 on the board is showing a dead short to ground.? Looking at the schematic this should not be the case, especially since the T501 coil has not yet been installed.
