[TenTec] Orion sub receiver getting no signals

[art N4UC]

Is it my imagination or are we beginning to reach the limit of the design life for Orions? All of a sudden it seems that the number of emails from people having strange problems with Orions has increased dramatically.  There sure seems to be a lot of dead Orions sitting on work benches wanting for scavenged boards (including mine).
