[TenTec] delta 580 on 10 meters?

[Kevin Purcell]

Or even easier when you disconnect the antenna does the noise go  
down? When you reconnect it does it go up?

If you can hear the difference then the ambient noise + galactic  
noise is higher than the noise figure of the RX. Depending on your  
location one or other will dominate.

Another possibility is to listen for a signal leaking out of a  
computer or a TV at a multiple of 3579 (7148, 14316, 28632).

Or call CQ on 28300. It's only dead cos everyone is listening.
