[IRCA] "Science Fiction PL-380"-- Pest Control Version

Hello All,   The first of the new hard-wired FSL models specifically designed to have an unusually sharp nulling capability is now a reality. With a "short and stubby" FSL design that emphasizes symmetry, isolation and a tidy RF reception pattern, this model can put all of my semi-locals

Thanks, Tim. I have no idea who the screecher is, but can a 250-watt FL station be doing this so widely up this far north? I know it comes in with Au cx. But. ... Had a bit this am but couldn't tell if stronger on wsw or south antennae. Saul Chernos Burnt River ON > Date: Sat, 23

Is WASN 1500 OH Youngstown on the air? Wikipedia says it's off due to technical issues. Web page is Asian and not radio related. Anyone close-by who might know? Saul Chernos Burnt River ON ___ IRCA mailing

Re: [IRCA] WASN 1500 OH Youngstown on the air?

If they are off the air then this might explain why I've never heard them here, unless they are the source of the screeching sidebands on 1500 (which I still here now at 1300 UTC). 73, Tim Tromp West Michigan On Sat, Jan 23, 2016 at 7:52 AM, Saul Chernos wrote: > Is WASN

Once again, congratulations Gary, better nulling than the 100mm length one, but somewhat larger diameter, is that correct? How does the weight and balance vs. the PL-380 compare? Amazing stuff to be sure. best wishes, Nick At 13:40 23-01-16, Gary wrote: Hello All, The first of the new

First a word of sincere thanks to Gary and others who have pioneered the development of the FSL antenna movement. And while I hesitate to add to his “To Do” list, I would like to encourage Gary to write the addendum to the article that details the construction of this version. My primary

There is a chance this is coming from Washington. The Nielsen "People-Meter" code generator has been modified to make it more "hearable" by the People Meters...some stations are pushing their audio processing to make the Nielsen signal even more apparent, in the belief that this will improve

[IRCA] 790 puzzle

I had an unID this morning on 790 at 1300 UTC (0700 EST). The dominant country station forgot to run their ID at the hour, leaving some dead air during which I heard a partial sign-on announcement. Unfortunately I couldn't hear the callsign, but the announcer mentioned they broadcast

Re: [IRCA] ​"Science Fiction PL-380"-- Pest Control Version

Fascinating discussion. I’m now wondering if it would be possible to feed a short, stubby FSL with 50 Ohm coax—perhaps through an isolator—then mount it outdoors on a rotor? If the FSL were mounted high above the rotor on PVC pipe, and supported by either wood or PVC, with the coax running at

Sigh! A good idea, but as you say, a small diameter Wellbrook loop fits the bill nicely, except for the lack of backside suppression, which is less of an issue at Rockwork. After my poor experience of a random wire to a SDR-IQ in Hawaii, I'm going to seriously look at bring a Wellbrook along on
