I have set up my ALinco DX-r8t/E SWL receiver in my 3rd floor office, connected to a Wellbrook ALA1530 active loop natenna, which sits on my window sill. I have no other options for an antenna, as I can run wire outside the building or outside my office.
I have a 3ft 12G solid copper wire from the ground terminal to a radiator pipe, and am beginning to put Mix31 ferrite beads on all of the electrical wires and PC cables in my office.
While AM comes in clear, HF (20m, 17m) is very noisy, and I can barely make out any voice. Even WWV 10.0 MHz is very noisy at 4am, when I can get a loud and clear signal from my mobile.
The window faces another 4 story building and I only get a gap of sky, so signal is probably poor.
Are there any other options I might try to cut noise and boost signal (within the office walls)?
