Yes, and a common mode choke at the output of the radio and a separate
ground between the radio and the PS migh cure the problem. I am on the 2nd
floor of a wood frame house with antennas overhead.

Subject: Re: [TenTec] Eagle problem?
These types of problems usually indicate that there is RF leaking back to
any any transceiver he might try, because his antenna is too close to the
shack, especially if shack is on second floor. One thing he could try is
putting quarter wave counterpoises (hook up wires) on the ground terminal
and leading them out the window to drop down the side of the house. A
second story ground wire to earth is useless as an RF ground, so he must
be made to understand the earthing wire is but for lightning safety from a
hit.
Ferrite chokes on coax, a good external tuner, etc. are things that can be
tried. Do not overlook bad coax, (Radio Shack?), with leaky shields.
I hope you can help the ham resolve the problem. BTW, does he have large
enough gauge wire between the power supply and radio, and twisted pair no.
12 as a minimum?
