Hi, Kris,
Probably the biggest difference is that when contacted by hams, Winegard
decided that this was not a major problem and that they didn't have to do
anything to address it.
AT&T, the operator of the largest installed database of the PX-421 wireless
modem jacks responded differently. After a slow start, they initiated a
complete, system-wide recall of the jacks they had installed. At last
report, over 90% of the ones they purchased have been removed from service.
If you are still having difficulties with your local system, I can forward a
brief summary of your case and the problems you have encountered to the
senior-engineering staff at AT&T. If it is a non-AT&T system, I can forward
it to our contact on the Society of Cable Telecommunications Engineers. If
it is coming from an "after-market" device (one of the several thousand sold
retail) operated by a neighbor, a letter from the FCC may be what is needed.
It is very hard to convince a neighbor that a device he or she bought at
CompUSA is being operated in violation of federal law.

If the FCC can come down hard on part 15 intentional radiators on
2.4 Ghz why can't they come down hard on the part 15 intentional
radiators that are ruining 80m CW (wireless modem jacks)? What's
the difference? Anyone know?
