When I operate on 75 meter SSB with my Orion, my computer beeps and
disconnects/reconnects my USB connected keyboard. Note that I do not have
this problem on 40 meter SSB. My computer is located on the second floor of
a brick house, and one end of my dipole is about 15 feet from my shack.
From comments made by others on this list, I may have to put RF filters on
the cables and wires connected to my computer. I am contemplating the use of
Amidon FT-240-77 ferrite toroids, which have an I.D. of 1.4 inches and cost
$9 each. If I buy in quantities of 10, is there a cheaper source for this
toroid?
Any comments or suggestions on this problem would be appreciated.
