This was also posted earlier to dx and contesting
reflectors, but was told this would be the best
place to tap the brain trust...


Arghhh...I'm listening for the 8Q7 operation thru
a wall of noise...caused by a neighbor charging up
her electric mini-wheelchair. I traced the noise
down last night but does anyone know why this contraption
would cause noise 3.5 - 29Mz with an S9+ girgling 
noise every 5Khz? What components in the charging
circuitry should I look for as culprits? Obviously
the gal needs to get around her home...
Thanks in advance,
John K7FD
