a knock on my door

ok guys i have a 600w apollo digital ballast ive been using for almost 2 and a half months. just got a knock on

my door i didnt answer, it was time Warner and they left a note on my door saying theres severe interference

coming from my house. Since i didnt answer he disconnected my internet but left my tv on..weird. So i shut off

my ballast the next day before they came over to find and fix the problem. Supposedly it was a broken cable in

my wall and they fixed and turned my internet back on. I dont want this to happen again and i want to know if

magnetic is the way to go? i could care less bout how inefficient magnetics are or how hot they get i just want to

know if it will stop giving off RFI?

i've used nothing but mags, over 30 ballasts with no failures or problems.

sure they hum a bit and they do create a bit of heat but seeing as i'm used to it i have no problems

anyone here with a magnetic ballast know if they give off any interferance. i did the am radio test with my digital and i cant use it in the same room as my ballast
