[TenTec] Century 21 audio hum

[Josh Gibbs]

Hi Curt,

I didn't mess with the bridge rectifier. When I removed the transformer
from the chassis, the noise went away. I've made a shield out of steel for
the transformer, but have not yet had time to install it. I will post back
with results when I get that done.

Also, Ed W3NR is mailing me a page containing info on a pre-amp RX mod
written by Dick Frey (former T-T engineer and designer of the C21). I will
scan that and post it when it arrives. I may give that a go as it is
supposed to improve the RX sensitivity significantly.

Hope everyone is getting ready for Field Day this weekend. I can't wait!
This will be my first Field Day as an Extra... passed the test last week!
