The LA County proposal, filed August 9, seeks FCC approval to develop an experimental system using four 10-MHz channels to transmit video images from helicopter-borne cameras to five remote receiving sites with active tracking antennas. The proposal targets the 2402-2448 MHz band. Amateurs have a primary domestic allocation at 2402-2417 MHz. In comments filed October 22 with the FCC's Office of Engineering Technology AMSAT-NA President Keith Baker, KB1SF, said AMSAT views the experimental TV operation "with the greatest concern." "AMSAT believes that any such grant would violate the spirit of Commission's own order granting amateurs primary status on much of the band in question," Baker said, "and could well disrupt amateur satellite and other amateur use of the band as well as jeopardizing its use by other existing occupants." Baker urged the FCC to deny the experimental license application because it poses the potential for serious interference to current and future satellites and could limit the use of the pending Phase 3D amateur satellite. The Phase 3D satellite includes transmitters and receivers on 2.4 GHz. The satellite is expected to be launched sometime next year. Baker also expressed concerns that a temporary experimental license could become a permanent fixture. The ARRL expressed similar objections to the proposal last month. The decision to grant the proposed experimental license is up to the FCC Office of Engineering and Technology's Experimental Licensing Division.

The FCC has proposed new emission guidelines that are just slightly more stringent than the current FCC standards. "We conclude that mandatory conducted emission limits continue to be necessary to control interference to communications services," the FCC said in a Notice of Proposed Rule Making in ET Docket 98-80, released October 18. The Commission announced plans to "harmonize" its conducted emission standards with international standards developed by the International Electrotechnical Commission, International Special Committee on Radio Interference--known as CISPR. The CISPR emission limits for consumer equipment are "approximately 5 dB more stringent below 5 MHz and 1 dB more stringent above 5 MHz" than the existing standards, the FCC said. "We believe that these standards address some of the concerns expressed by ARRL" and others in response to last year's FCC Notice of Inquiry on the issue, the Commission commented. The Commission said it was not persuaded by a National Association of Broadcasters' suggestion to impose much tighter standards--22 dB greater than present--to protect AM broadcasting. Interfering devices include such common household appliances as computers, TV sets, and microwave ovens. Conducted emissions result from RF voltages imposed on the ac power line, which can, in turn, act as an antenna. In general, the FCC's current conducted emissions limit is 250 uV. Equipment manufacturers had argued to relax existing limits to keep down production costs, while the ARRL and others representing spectrum users had asserted that the existing limits were not tight enough. In response to the earlier NOI, the League had commented that the proliferation of Part 15 and 18 devices over the past decade had resulted in "a marked increase in RF noise from conducted emissions generally." The FCC said it agrees that that standards on the amount of RF energy conducted onto the ac power lines "are required to control potential interference to users of the radio spectrum below 30 MHz." It also invited comments on expanding the frequency range of the conducted emission limits from the current 450 to 30 MHz to the 9 kHz to 30 MHz spelled out in the CISPR standards. The ARRL has proposed that the FCC allocate new LF amateur bands at 136 kHz and at 160 to 190 kHz. Comments on the NPRM are due 75 days after its publication in The Federal Register, and reply comments are due 30 days later.

The co-primary allocation for Dedicated Short Range Communications systems at 5.850 to 5.925 GHz includes the upper portion of a secondary Amateur Service allocation. Hams share 5.650 to 5.925 GHz with government radars and nongovernment fixed satellite service uplinks. The FCC already has allocated 5.725-5.825 GHz for U-NII devices to provide short-range, high-speed wireless digital communication under Part 15. In releasing its Report and Order in ET Docket 98-95 October 22, the FCC said the 5.850-5.925 GHz band would be devoted to a variety of Part 90 DSRC uses such as traffic light control, traffic monitoring, travelers' alerts, automatic toll collection and traffic congestion detection. Other proposed uses of ITS would include electronic inspection of moving trucks and emergency vehicle traffic signal preemption. The Commission said that amateur organizations and licensees "raised the majority of DSRC spectrum sharing concerns" in their comments on last year's Notice of Proposed Rulemaking on the issue. In its September 1998 comments, the ARRL said the FCC was proposing too much spectrum at 5.9 GHz for DSRC deployment. The League had asked that the FCC compensate the Amateur Service by elevating remaining Amateur and Amateur Satellite allocations at 5.650 to 5.725 and 5.825 to 5.850 GHz to nongovernment primary "to insure against future preemption by nongovernment services with higher allocation status." The FCC Report and Order did not specifically address the ARRL's request for elevation to primary status, however. In the R&O, the FCC said it was "sympathetic" with the League's concerns that the ITS and U-NII allocations could impact amateur use in the band but said hams have 275 MHz in the band and most ham use is for point-to-point networks. Given amateur radio's inherent frequency agility, the FCC said it believes "spectrum sharing between the amateur service point-to-point links and DSRC operations is viable." DSRC operations in the 5.850-5.925 GHz band "are unlikely to receive significant interference from or cause interference to amateur operations," the FCC said. The FCC encouraged ITS entities to "informally notify the ARRL or the local amateur service community" of their intended operation. The FCC has proposed a maximum of 30 W EIRP for DSRC systems, but the rules will require ITS licensees to use the minimal power necessary. The FCC says it will defer consideration of licensing and services rules and spectrum channelization plans to a later proceeding.

I have been in the EMC world for almost four yrs and this is a good step to reducing the compliance rules for EMC. I am waiting to see the comments from the rest of the industry. There are 2 different view point, 1 that the current rules need to be relaxed and 2 that the current rules need to be tighter. In the grnad scheme of things CISPR is 3 dB from 0.450 to 5 MHz tighter and 6 MHz tighter from 5 to 30 MHz. I would like the FCC to look at the radiated emissions limits and adopt them as well. This would mean on less report that I have to ask a po for. The lab we do business with, who also laid me off back in March, charges 500 for a CISPR 22 Class A report. They decided to split each different limit into a different report. The radiated emissions limits for CISPR are also tighter but it should make it easier to have radios in the same room as IT equipment. 73, Guy Story kc5goi@kc5goi.net http://www.kc5goi.net 940.243.0754 ----- Original Message ----- From: Dewayne Hendricks To: TAPR FCC Regs Discussion List Sent: Friday, October 29, 1999 4:18 PM Subject: [fccreg] FCC REVISES CONDUCTED EMISSION LIMITS > FCC REVISES CONDUCTED EMISSION LIMITS > > The FCC has gone along with recommendations from the ARRL and others to hold > the line on conducted emissions below 30 MHz from unlicensed consumer > electronic and industrial, scientific and medical devices operating under > Parts 15 and 18 of the Commission's rules.
