Lee,
Higher powered audio amplifiers have a time delayed relay switching the
speakers after the amplifier has switched on. When powered down the relay drops
out before the speakers give a pop as well. I think this is a simple
modification that can be done without too much drastic changes - should be eay
to revert from too should it be required. IMHO you can even do this "outside"
the rig if you use a headphone or external speaker.

Subject: [TenTec] OI Audio 'Pop'
When I power my Orion I on or off, there is a fairly loud ?pop?, which is
significantly louder on power-down. It happens with both the headphones
and
the speaker, and the level is not affected by the AF gain setting.
I am the second owner and have only had the rig for a few months. I went
through the manual, then phoned TT service. While the tech exhibited the
same excellent level of courtesy and sincere caring I have come to expect,
this was the first time I came away from such a conversation without a
solution?although it was suggested that a faulty capacitor might be the
cause.
So, I would certainly appreciate any guidance you-all could give me.
Tnx/73, Lee, K7VL.
