[IRCA] 738 RFO good tonight
Noticed quite good reception of RFO with French talk at 06:13 UTC. About the best I've heard them in a long while.Walt. ___ 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] Strange image
Patrick, I suggest we keep our terminology straight as there are two entirely different things here: Something produced by a transmitter and really propagated anywhere but on the fundamental frequency is a spur: Something produced only inside a receiver is an image. It may be difficult to tell which is which in some cases, like this? 73, Glenn Hauser [NRC-AM] Strange image This evening near LSS, on the Drake R8, I was getting a weak image on 500 kHz from an UNID Seattle station. In checking I found it was KJR-950! Now KJR is strong here off the NE EWE, but only S9+20 DB at the time. The image was not moving the S Meter, but it was totally audible on peaks. Another funny thing was the image was fading to non existant up to audible and yet KJR 950 wasn't! I only noted this on the NE EWE. In checking a couple hours later, no such image was found on 500 kHz. I don't even get images from my locals, but I did log an image on 522 kHz some years back from the ABC TX site at Sydney, NSW with 576/630/702 kHz. I even QSL'd it. The OM wrote me back stating they knew about the image the transmitter QTH was putting out as it was also logged in New Zealand. I know Drake is famous for a low noise floor, but it would be interesting to know how much power these images were putting out. I will check to see if the KJR image is back tomorrow. 73, Patrick Patrick Martin KGED QSL Manager ___ 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

[IRCA] 9 Foot Longwave Box Loop (and other projects)
Hello Guys, Wrapping up the fascinating experimentation with PVC-frame tuned passive loops, I decided to push my luck on a couple of ambitious projects, both of which exceeded expectations. A 9-foot (diagonal) PVC-framed box loop was built for LW reception, using 1.25 diameter PVC for rigid framing. About 490 feet of #18 wire was wrapped in 19 turns across the PVC frame, with the frame offset from the coil for maximum performance. Using the standard tuning capacitor from eBay's crystalradiosupply, this monstrous antenna tunes from 167 kHz to 444 kHz, providing serious gain on any frequency near resonance. Not being a particularly active LW DXer, I assume this tuning range is suitable for some LW DXing :) Otherwise, I'll just add a few more turns to get the coverage down to 150 kHz. Using this monster in my backyard, a slew of LW beacons was booming in on the Tecsun PL-600 just prior to sunset, including the following morse code stations: GR and LU around 214 kHz, HQ on 235 kHz, BVS on 240 kHz, HE on 245 kHz, QCD on 251 kHz, VR on 266 kHz, and FHR on 284 kHz. Only the QCD beacon was audible on the stock PL-600-- the others required the 9 foot box loop for reception. The other ambitious project was a 5.8 foot (diagonal) PVC loop with removable parts, that can easily be assembled by an apartment or townhouse dweller in a park, or ocean beach (or anywhere else). This project used silicone rubber sealant on the coil windings where they crossed the PVC tubes, making it easy to get perfectly symmetrical coils every time, when the loop is assembled out in the field. It takes about 30 seconds to assemble, and the broken-down version will fit easily in any compact car. Full details on these and other PVC loops will be contained in an upcoming article, which is nearing completion. 73, Gary DeBock **The Average US Credit Score is 692. See Yours in Just 2 Easy Steps!

[IRCA] west coast TA LWBC
Happened to check the radio just now, 0350 utc, and 162 France at poor/weak level, 171 Morocco at poor level. Usually it's just Morocco if I hear anything, so sort of unusual. Only a poor het on 1215 for MW.

Re: [IRCA] west coast TA LWBC
The issue with the Eastern beverage tonight, I am getting too much static from a storm that is coming in tomorrow with possible wind gusts to 65 MPH and a lot of rain. Very unusual for this late in the season. The EWEs are much quietier. I need to add more ground rods on the NE EWE though, to get a sharper null. It workd well, but it could work better. Two five foot copper pipes on both ends is not enough. Copper has come down in price which is nice. 73, Patrick Patrick Martin KGED QSL Manager ___ 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] 9 Foot Longwave Box Loop (and other projects)
If you could add a couple more wraps to drop it to 150 khz, you would cover the whole LW band, as the broadcasters start at 153 kHz and go up to 279 kHz. It would be interesting to test that loop against other kinds of antennas. 73, Patrick Patrick Martin KGED QSL Manager ___ 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] 9 Foot Longwave Box Loop (and other projects)
Hey Gary: Wow, and I thought my 42 diagonal LW box loop was effective: yours probably has another 6 dB gain if my math is correct. Are you hearing the LW from Europe tonight that guys on the IRCA board are talking about?? If one wanted to use this behemoth for LW beacons, which go from about 200 to 530 khz, you would probably need about 15 turns or so; perhaps 375' of wire. My loop tunes 200 khz to about 600 khz, for which I had to use about 330' of wire, I think. To do both the LW band down to 153 khz all the way through 530 khz for beacons, I guess you'd need to switch out some capacitance, or wind the coil in two contra-wound coils and switch those out parallel/series. So, what are you bribing your neighbors with such that they don't run you out of town Kevin S Bainbridge Island, WA If you could add a couple more wraps to drop it to 150 khz, you would cover the whole LW band, as the broadcasters start at 153 kHz and go up to 279 kHz.
