Title: A Military OOPS, Wrong Frequency? Post by: AB3L on December 05, 2006, 07:13:41 AM http://www.msnbc.msn.com/id/16035362/?GT1=8816

Part 15 of the CFR47 has been around for a long time. Part 15 consumer equipment must accept interference from licensed frequency users. RF immunity is the responsibility of the manufacture.

I would think military use supersedes consumer conveniences. Hopefully the manufacturers will reimburse the customers for new units on different frequencies.

Yes, time for a product recall. Quote "They have turned it off to be good neighbors," he said... Technically, the Air Force has the right to the frequency, which it began using nearly three years ago at some bases. Signals have previously interfered with garage doors near bases in Florida, Maryland and Pennsylvania... David McGuire, whose Overhead Door Co. received more than 400 calls for help, said the Air Force may be able to slightly adjust the transmission frequency to solve the problem. If not, it will cost homeowners about $250 to have new units installed. The Air Force needs to be more hard-nosed about this issue. They could cite national security issues. Give the manufacturers and users 30, 60 or even 90 days to resolve the problem before returning to the frequencies. Otherwise, this leaves a second dangerous precedent. The first precedent was set when the FCC refused to open a LF ham band in the 160-190 kc/s range due to objections from the electric power industry, concerned that ham signals might interfere with the Part 15 Power Line Carrier communications the utility companies transmit down their lines to control substations. Otherwise, when a ham vs Part 15 device conflict arises, as for example with BPL or "Homeplug" devices, pressure can be placed on the ham to avoid certain licensed frequencies. "If the Air Force can move frequency to accomodate garage door openers, amateurs can move frequency to avoid (BPL or whatever else) interference." |
