RAC Ontario Section Bulletin for August 14, 2010



ITEMS OF INTEREST

1. Grounding for Lightning Protection

Radio World has a series of three “Tech Tips” on how to ground
commercial radio station antennas for lightning protection.  Much of
that information is also relevant to amateur stations.  See the
articles at tinyurl.com/grounding-1, tinyurl.com/grounding-2, and
tinyurl.com/grounding-3.

2. Wind Loading Calculations

Contesting.com’s Wiki has a handy reference for antenna wind loading
calculations.  You can see it at tinyurl.com/2elnzko (Two Echo Lima
November Zulu Kilo Oscar).

3. RFI from LED lamps

Many hams have discovered that CFL (Compact Fluorescent Lamps) emit
radio frequency interference.  Some have hoped that LED lighting will
solve the problem.  But New Zealand’s Radio Spectrum Management
department reports that LED bulbs can produce RFI, too.  The problem
is that the current regulators in LED bulbs use switching circuits
similar to CFLs.  So check those LEDs for interference before you
install them.

4. ARRL Contest Corral

published in QST Magazine.  This list includes all ARRL-sponsored
contests and most other major ham radio contests. Visit

    Hi, thanks very much for the link to Radio World’s series about grounding by Cris Alexander. Just a PS to point out that the “Radioworld” banner seen in the photo you posted appears to be that of the amateur/ham supplier that has a similar name to ours. We’re not related. Thought you might want to know, for complete journalistic accuracy!
