Re: [IRCA] Wellbrook Large Aperture Loop Antenna ALA100LN

Walt: I'm curious; does LW signal strength improvement justify a 100 ft. circumference or beyond? I s'pect there's a practical/empirical-best-size; probably beyond 60 feet...but where would you suggest stopping? Cheers! Mark Durenberger On The Road Again -Original Message- From:

Based on the frequency offset, I think it is WFED 1500, DC. I'm seeing noise spikes 100 hz, 200 hz, 300 hz away from 1499.990 - which is WFED. Aaron ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca

Re: [IRCA] Wellbrook Large Aperture Loop Antenna ALA100LN

I have had stunning LW reception from the "far east" -- meaning Russia on Long wave - with a Hula-Hoop sized ALA100 home brew loop. Simply, anything much larger than 20 or 30 feet around is completely pointless. On Thu, Feb 4, 2016 at 4:43 AM, Mark Durenberger Mobile < ma...@durenberger.com>

Re: [IRCA] Wellbrook Large Aperture Loop Antenna ALA100LN

Mark, I think that Colin and Don are correct. Super large diameter ALA 100 loops don't seem to improve things substantially on LW. Don't know why, but that's the way it is. 73,...Walt On Thu, Feb 4, 2016 at 12:43 PM, Mark Durenberger Mobile < ma...@durenberger.com> wrote: > Walt: I'm

Re: [IRCA] Wellbrook Large Aperture Loop Antenna ALA100LN

My understanding from Andrew Ikin was that a loop considerably different in size from that for which the amplifier is designed, creates an impedance mismatch that eats into the gain that is available from the amplifier. best wishes, Nick At 06:37 05-02-16, you wrote: Mark, I think that

The “warbler” was on again tonight—audible from just after 5PM until I returned home just after 7PM. WFED in Washington, DC was audible at times in the mix, but not strong enough to tell if the signal is riding on their sidebands. Signal wasn’t quite as strong tonight as last, but still easy

[IRCA] Noise on 1500

It's fairly strong tonight, though with skywave fading... I hear no "wobbling" or warbling, but rather a fairly steady tone of about 500 Hz, equally strong on both sidebands. It's not a "clean"-sounding tone by any means--definitely sounds like someone with a serious transmitter problem. From

Amigos, I took my CCrane Skywave out on the deck tonight around 2115 EST, and heard the strange noise on 1500 that some are reporting. It was pretty faint behind WFED, but distinctly there, kind of high-pitched & rough like a steady bandsaw heard faintly from a great distance. What I have to

Re: [IRCA] Wellbrook Large Aperture Loop Antenna ALA100LN

I use a diamond shaped loop of wire ~80m for my ALA-100 and hung from 35m high. This size is just on the verge of overloading from my locals, which are 80 km away. This size seems to give good performance in general but is not exceptional on longwave bc. For example, 189 Iceland is often very

Re: [IRCA] 1500khz someone with very noisy sidebands

Brett, That is nearly exactly what I’m hearing here near Birmingham. The warble part is much stronger here, literally dominating the channel at times. At first, I too thought it might be local interference or QRM but after a few times listening to it, I can tell you that is not the case.

Re: [IRCA] [NRC-AM] Noise on 1500khz

I’ll try to take some bearings tonight using a portable flag antenna that I have for mobile DXing. Everything else I have is unidirectional or omnidirectional. Cuba sounds more likely to be than a domestic daytimer. When I heard the signal it was dominating the channel—difficult to do
