Implementation Versions Affected |
| No ground on resistor |
R401 - Sheet 4 |
IC401 10MHz input |
Link with short wire to ground side of L201 |
All implementations - input to logic buffer stages |
| No Vcc connection between via and R302/C303 |
Sheet 3 - LF Multiplier |
LF multiplier stage has no +5v supply |
short wire, or blob solder across from hot side of C303 |
Any build version which requires an LF multiplier or amplifier |
| IC401 pins 5 and 10 connected |
Sheet 4 - Logic stages |
Divider input/reset operation |
cut (top side of PCB) and strap pin 10 (underside of PCB) to via leading to SJ901 |
Any build version which requires a second divider stage. This correction MUST be carried out before IC401 is inserted |
| Documentation Issue - R203,204,205 |
Sheet 2 - Diode Multiplier/Amplifiers |
Output Attenuator |
PCB Marking shows resistors as R11, R12 and R13, not R203,204,205 as marked in documentation |
All versions |
