If you are faced with an interference problem and your neighbor is convinced that it's that "ham radio thing," help is available in evaluating the problem. Your ARRL Section Manager can refer you to your section's Technical Coordinator and to other local sources of assistance.
The ARRL Technical Information Service (TIS) can also refer you to appropriate sources of assistance. TIS can be contacted by mail at: ARRL, 225 Main St., Newington, CT 06111; by telephone at 1-860-594-0214; by facsimile at 1-860-594-0259 or by e-mail at firstname.lastname@example.org.
