[TenTec] Orion-2 slight problem...

[David E. Shelton]

Paul at TT, knew exactly what it was when I called this AM. The speaker
magnet is not shielded and is causing a component on the board immediately
below it to malfunction. I presume it is in the audio chain. Replace that
component, a choke, or shield the speaker magnet and problem solved. I
removed the speaker as a test and problem solved, no further issues.

N4IN asked about:

"...then gradually a hum will start in on the audio...(etc.)"


Is it 60 Hz or 120 Hz or something else? If power feeding the rig is
pure DC, then how do you account for 'hum'? Something oscillating
within, or maybe hum being picked up from an external source such as a
power transformer too near to the rig? Please describe.
