what would cause volume to sudden ramp up to full?

Wolf,
What the heck 'ya doing playing Helicopter when you're supposed to be listening? Pay attention.

Dish Network has an RF remote for some receivers.....use it from the other room.

I found out my neighbor had the same remote so I had fun for a while......I could see their TV while standing on a ladder in my kitchen....So, I'd flip channels for them. Use your imagination!

It is true that the helicoptor distracts from listening, but it only flies for 10 minutes maybe (before needing recharging) so it's a sacrifice I feel I can make. I never fly it when listening to LPs as I'm afraid I'll crash it into my turntable...so there's that.

"when operating my little remote indoor helicoptor...I've had the helicoptor hovering in its gyro mode"
...while playing the soundtrack to Apocalypse Now? Awesome.
