Ron et al, I disagree with the last sentence regarding RFI due to traffic
signals on 2m, at least within Arizona (Prescott [my home QTH], Phoenix,
Flagstaff, Tucson, and many other AZ locations). My Kenwood TM-707G is
"staticed-out" on any 2m freq within maybe 20'-30' from the control box. I
presume it's a function of the manufacturer of the traffic control device
rather than traffic lights in general. In any instance, I've found I need to
turn off my mobile VHF/UHF rig while in town (I don't do HF from my vehicle;
too distracting).
Related to same, I frequently experience brief static bursts on the road from
diesel-powered vehicles (most often long DX 18-wheel truckers, bless them for
maintaining our commerce), the RFI possibly being emitted from the fuel pump
but also possibly from newer computerized engines. Distance is maybe only 10'
to 20', usually while I'm beiong passed. The RFI is brief enough such that it
usually doesn't interrupt a QSO.
My pet peeve is rural, generally unmaintained roadside transmission lines which
leak RFI, often along long stretches (miles) which completely knock out
broadcast AM (my Sirius is unaffected except by overhead bridges). I have
contacted Arizona Power Supply/Service on this but APS has been completely
unresponsive. And I'm not about to challenge the titanicPalo Verde Nuclear
Power structure...
I don't think AZ has progressed to energy-saver LED traffic lights (let alone
mandatory motorcycle helmets, recycling), where Stop signs are just a
suggestion, use of turn signals seem to be illegal, and my vehicle insurance
rates jumped 15% from my old NY QTH when I moved to AZ in 2004. AZ seems to be
stuck in the 20th century.
Life will go on. Nevertheless, I am an active ARES/RACES member and I don't
like the potential for RFI on any band during a potential nor realized EmCom
event.
