1. Regarding grouchy neighbors, see the “Filters?” topic in the forums. oldguy is (or was) apparently having a problem with a neighbor.
2. I have to disagree with lpam somewhat in this particular case:
a. Users of Part 15 devices must not cause “harmful interference,” meaning to licensed radio services. Therefore, if the zipperhead complains about his TV (or AM or FM radio when listening to licensed stations), pkradio must do whatever it takes to stop that interference, or stop using the FM box.
b. However, regarding the zipperhead’s cordless phone, that is just another Part 15 device. Subsection 15.5(b) says:
“Operation of an intentional, unintentional, or incidental radiator is subject to the conditions that no harmful interference is caused and that interference must be accepted that may be caused by the operation of an authorized radio station, by another intentional or unintentional radiator, by industrial, scientific and medical (ISM) equipment, or by an incidental radiator.”
Also, Subsection 15.5(a) says in part:
“Persons operating intentional or unintentional radiators shall not be deemed to have any vested or recognizable right to continued use of any given frequency by virtue of prior registration or certification of equipment…”
To me, this says that Part 15 devices, and the users of them, are not protected from each other’s interference, and the zipperhead would have no basis to complain about interference from a Section 15.239 FM box to a Section 15.233 cordless telephone.
