The editor had a very busy work schedule this month, resulting in a shorter than normal newsletter. Maybe that's a good thing.

Garage Door Interference From CGC Communicator

Mobile Installations From ARRL Contest Rate Sheet
Don't forget that newer cars can be susceptable to excessive RF. The ARRL Technical Information Service provides a pretty good background on new car installations at www.arrl.org/tis. Although sometimes difficult to find, the US automobile manufacturers publish guides for installing radio equipment, grounding, cable routing, noise management, and so forth. Good infomation to review before the air bag goes off on the first transmission:

Schematic Diagrams From ARRL Contest Rate Sheet
A freeware schematic drawing program that seems to be straightforward to use is TinyCad. It has quite a good library of parts and was easy to get running. The current version includes a number of improvements over the old version. Download it at:

Amateur Radio Spectrum Act of 2005 From ARRL Letter
The Amateur Radio Spectrum Act of 2005 was introduced into the US House of Representatives by Rep Michael Bilirakis (R-FL). The current measure requires the FCC to provide "equivalent replacement spectrum" to Amateur Radio if the FCC reallocates primary amateur frequencies, reduces any secondary amateur allocations, or makes additional allocations within such bands. More than 100 lawmakers agreed to cosponsor similar legislation in the past. With one co-sponor already signed on, the focus is to attract additional co-sponsors and having identical legislation introduced in to the US Senate. The text of HR 691 is available on the Government Printing Office Web site.

New Epoxy Discovery From Newsline
There is a new epoxy cement can release the adhesive bond by the application of a small electrical current. Controlled from a 9 volt battery, the bond is broken with no damage to the metal substrate. Read more on this solution.

On the BPL Front From Multiple Sources
The Rochester ARC does not have any new information posted on their web site.

The ARRL has petitioned the FCC to take its broadband over power line (BPL) Report and Order (R&O) back to the drawing board. The League called on the Commission to ''reconsider, rescind and restudy'' adoption of new Part 15 rules spelling out how BPL providers may deploy the technology. The ARRL's petition asserts the R&O fails to adequately take into account the technology's potential to interfere with Amateur Radio and other licensed services.

The Borough of Chambersburg, Pennsylvania decided against BPL plans. The Cumberland Valley Amateur Radio Club spearheaded opposition to the plan through an informational campaign. The local newspaper indicated there wasn't enough money in the municipality's Electric Department budget to go forward with a BPL deployment this year.

BPL is advancing in San Diego, California. The San Diego Gas & Electric Company made a presentation to the San Diego DX Club, announcing the utility's plans to deploy multiple BPL test sites in San Diego County. Although unimpressed by early BPL equipment, SDG&E are encouraged by their December visit to Cinergy's BPL system in Cincinnati.

Across the big pond, Radio Netherlands posted to its website a very informative program called Wake up and smell the coffee. The show is all about why the short-wave broadcast industry should be doing more to fight BPL. You can read and/or listen.

Down under, the New Zealand Amateur Radio Transmitters and the Wireless Institute of Australia say that they are pooling their resources on the BPL issue in the effort because problems involved in its introduction are similar in both nations. The NZART and the WIA say that they plan to work as a team in an effort to achieve a positive outcome on this issue for Amateur Radio operators in both countries.
