Upon a cold start the audio in the speakers has a distinct a/c hum that is multiplies 10 fold when the tune button is pushed with or with the tuner in line, loading into a dummy load. It's deafening.
"...The Orion does not seem to indicate the actual level of RF output on the meter; rather it seems to show the percentage of full power the operator sets - that is, 100 indicates 100% of full power
"...Yes, high temperatures are fairly normal. Some users have worried that that might be a problem -- cooking some of the components prematurely. Installing an internal fan can help even things out q
