My FT-990 often does not receive well after it powers up. i.e. Tuning across various bands, changing from one VFO to the other, few if any signals are heard. Briefly tuning up (CW) with low power will cause the radio to receive normally again. The radio sat idle for years while I was deployed.

I suspect the antenna switching relay contacts are the culprit. Do you concur?

Suggestions for (easily) cleaning / burnishing them?
