Could any experienced Radio Amateurs, repair technicians or just knowledgeable persons who contribute here, kindly weigh in on the following?
I have an HF (Radio Amateur) transceiver with a particularly puzzling fault.
Sometimes it will fire up and run to original specs. without a single issue over as many hours as one decides to test. On other occasions, upon hitting the power switch, the meter will light up but the radio will not emit a single sound or function in any way.
I cannot induce the fault when it is functioning normally or coax it out of an inoperative state when it is in that mood. I refer to thorough routine checks such as looking for loose connections and seating and unseating connectors and so on. (No point in pretending that I pulled out a service manual and started looking for where voltages should be etc.)
My questions are: In your experience, does this indicate that the equipment should be replaced?
Would this be a standard recommendation in the repair trade based on years of experience?
If so, is it because the components or the connections to them are deemed unreliable and not cost effective to diagnose?
I look forward to your kind comments.
PS: - The transceiver is the Icom 745
