I have an issue with my Racal Dana 1992 counter.
Just recently, it started locking up randomly while taking readings. That seems to have gotten better.
It also locks up when going into standby, and will not recover unless power cycling the unit.
I haven't used it in a while, and it just started. Bought it about 2 years ago.
My garage is not heated unless i'm in there working, so I'm not sure if it was temp related.
But it's pretty repeatable now, even with the garage warmed up.
I have the service manuals, but I'm not exactly sure where to begin looking. Nothing on the flow charts about lockups.
I may try to remove and reseat the CPU and OCXO, in case it's a dirty socket.
Power supply voltages look good, and the unit is still very accurate compared to GPSDO.
All performance tests in the manual pass.
Anyone else ever had this issue, that can point me in the right direction to troubleshoot, so I'm not wandering?
Thanks!!
