[IRCA] QRM from Lights
I just installed my first LED bulb, a Philips 100 W equivalent. So far, no noise. I'd be interested in hearing from anyone who's tried other brands, particularly Cree. I also have several 100 W equivalent halogens. Fortunately they're not producing any noise, either, but that could be because they plug into a standard lamp socket like a regular incandescent rather than using a power supply or transformer. I never had any noise with CFLs, but I quit using them because the light quality and lifespan both were crap, regardless of brand. ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com

Re: [IRCA] QRM from lights
I have no noise from the 120VAC ones...just the low voltage switching power supplied ones. Halogen lamps are very noisy. I stayed with a relative several years ago, and from the opposite end of a huge house, I knew immediately when she turned on her reading light. My radio reception was destroyed immediately. Halogen or AM DX.pick one. Mike Hawkins On Thu, May 15, 2014 at 11:47 AM, Saul Chernos wrote: Just had some halogen track lights installed at the Burnt River DX site.

But this new system is creating a terrible buzz on AM that only goes away when I turn them off. The noise carries a fair ways - beyond where my coax goes to the external antenna.

Re: [IRCA] QRM from lights
It's not the lights but rather the low voltage switching power supply converting 120VAc to 12V DC. I had the same thing next door but they let me swap them out for 120V halogens rather than the 12V ones. There really is not much you can do with these supplies to make them quiet as the signals they produce are real and nasty. Steve Just had some halogen track lights installed at the Burnt River DX site. They're billed as "LED compatible, for what that's worth, and it's also labeled as a 2-wire track system. System is on a dimmer that never previously caused problems when it was either off or set to full brightness.

The original KBIM-FM was 94.9 and it got out well by tropo to the east, but I suppose they were divorced long ago. Now NRC AM Log shows the FM translator of 910 is on 93.7, K229BV, and 910 is only 500 watts at night with pattern a circle tangent south, no good for us; yet KVIS` pattern is a tight figure-8 toward Enid. Something seems amiss here with one or both, or just a propagational fluke (Glenn Hauser, OK, DX LISTENING DIGEST) ** U S A. 1510-, May 9 at 0532, ESPN Radio is dominant, looping NE/SW, and about 5 seconds ahead of ESPN on 1500 KSTP. This is obviously KCTE Independence MO (circa Kansas City), 15 kW *daytimer* cheating yet *again*, *and*, *always* off-frequency far enough to cause an audible heterodyne. Poor WLAC doesn`t have a chance, only as a carrier to het. (And then there was another 1510 daytimer logged a few nights ago around midnite, WQQW circa St Louis, but not tonite). Who cares? (Glenn Hauser, OK, DX LISTENING DIGEST) == UNIDENTIFIED. 960, May 14 at 0502 UT during KGWA Enid Fox-hole, among the sigs audible with KGWA hummy carrier nulled as much as possible, is one playing ``Let It Be`` instrumentally. I have heard this more than once during the hole, so it may be a midnite tradition at some station, possibly musical WABG Greenwood MS, tho it`s nominally Blues format. Or a (pseudo)-Catholic station? (Glenn Hauser, OK, DX LISTENING DIGEST) UNIDENTIFIED [and non]. 1120, May 15 at 0605 UT, romantic music in Spanish with KMOX easily nulled, otherwise making SAH of 5 Hz. Seems to alternate slow tunes with upbeat banda ones, segués, and fades during announcements. 0613 UT, ``La Nueva 11-20 AM``; next break a partial phone number (for requests?) -5100. I could not detect any certain religious overtones, tho some romantic-sounding tunes have lyrix that are axually lovesongs to Jesus. So is it KEOR Catoosa/Tulsa (site really Sperry where we visited it), a.k.a. Radio Victoria, daytimer at night? The KMOX null to the SE is best for this, which is slightly south of east. Or is it KTXW, Manor/Austin TX, new station from the south with 155 watts at night, which had been Spanish, but per a report in radio-insight.com was to change format May 12 to English religion, formerly on KLGO 1490? Is this confirmed around Austin? Or neither? Anything happening with the ``silent as of Oct 2002`` (per NRC AM Log 2013) 250-watt daytimer, KLIM in Limón CO? Unlikely it`s a Mexican, as there are none in the north/east. May 15 from 1650 to 1702 UT, I monitor by groundwave KEOR; for enough signal I have to use the caradio and drive around the block to find a quiet enough spot amid the neighborhood noise level. Mostly music which may be partly secular, one song about ``ruiseñor`` = nightingale, or were they saying ``Jesú-señor``? But after a 1656 UT ID as ``Radio Victoria, 11-20 --- esperanza``, definitely praise music with those key-shifts upward; 1701 UT ToH ID as ``Radio Victoria, KEOR, 11-20 AM, Tulsa, Oclajoma`` --- everything including the call letters pronounced only in Spanish; ads, and into talk show `Conflictos del Corazón` (Glenn Hauser, OK, DX LISTENING DIGEST) --- End Message --- ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.
