You didnt say if it worked....assume it did....

Short of a lot of stuffing around, the clamp on ferrite interference
cores are worth a try - then try
if the cables you have run have spare conductors, ground them all at
each end. Maybe double up on the power one on pin 8 - the thing gets
its power from the receiving computer, could be a bit iffy what with
voltage drop on your feed cable...

Oh, and BTW Karl - you are aware you are committing a Federal Offense
by running an unlicensed radio transmitter causing interference to
your wifes radio. Possibly a lot of other radios as well.. Tsk
tsk....G..
