Koert, Check all components to be certain they are inserted with the correct orientation. Not only the ICs and diodes have a direction but the R-PAKs on the front panel board are not reversible, pln 1 os on the left if you are looking at the side with the label.
There is a DC voltage table in the back of the manual that may be helpful, but the pushbuttons and 3 of the controls are multiplexed groups which makes analysis by only DC voltage readings difficult. You should also check all the soldering at all connectors on the Control board and RF Board too. The signals from the microprocessor folw from the control board through the RF Board and then to the Front Panel. Look carefully, your most likely problem is a bad solder connection or an incorrectly placed component. 73, Don W3FPR > -----Original Message----- > > I just finished the front panel, control board and the beginning of the RF > board.
