The INFO 080 message means that the MCU (Control Board U1) is not communicating with some other firmware IC over the AUXBUS signal line. The only other controller that is present at this stage of your build is the MCIO in the middle of the RF board.
I would suggest that it is a solder connection that is at fault. Check the soldering at RF Board U1 pin 28 as well as resistor R64. On the control board check U6 pin 40 and resistor R6. For completeness, you should also check the Control Board to RF Board connectors CB P2 pin 28 and RF J7 pin 28. Those double row connectors anr numbered with odd numbers down one side and even numbers down the other side. Pin 2 is opposite pin 1. 73, Don W3FPR On 10/25/2012 12:10 AM, AC8HU wrote: > However when I proceded to the VCO Test, the > problems started - with the first appearance of the Info 080 message.
