Boomer found these. Anyone ever had experience with these TX's?     https://www.sjvbroadcastservices.com/      The AM units could be used for Part 15 Carrier-Current, but couldn't really use the FM's for anything permissibly here.

Huh? / Archive . org getting sued? Here we go...

« on: April 01, 2023, 1837 UTC »

Any of us using and posting INFO on  www.archive.org  may have seen this coming sooner, or later.

"The Fight Continues

Here at the Internet Archive, we’re deeply grateful for our community—the partners, patrons, and donors who help us thrive. Your support has proven especially valuable during a lawsuit brought by four major publishers that has aimed to put a stop to our library lending.

A lower court decision released on Friday ruled in favor of the publishers. This is a blow to all libraries and the communities we serve—but the fight is far from over.

We will appeal this judgment, continuing to defend the rights of libraries to serve their patrons, and the rights of readers to access books. We will also continue our work as a library. This case does not challenge many of the services we provide with digitized books, including interlibrary loan, access for the print-disabled, and ongoing donation and preservation of books.

Libraries are a pillar of democracy. They have an age-old role in providing access to knowledge for marginalized communities and preserving knowledge for future generations. As we push forward with our vital work, we hope that you’ll continue to stand with us.

We are powered by donations from individuals like you. If you find our services useful, please consider contributing to help us in our mission to build the web we deserve. "



So, if you see anything of use and interest there, suck it in, while you can! Including my site:  https://archive.org/details/@thadood

Huh? / SWL'ing Survey? Eh... Why not???

« on: March 12, 2023, 1940 UTC »

Huh... Been a while since I've seen any surveys on radio gear. Just some heads-up that you have to scroll down to about mid-page for the survey choices and those DOT's to fill in.   https://swling.com/blog/2023/03/survey-what-type-of-radio-is-your-daily-driver/

https://labsdl.wordpress.com/2018/09/06/interesting-am-broadcast-antennas-part-1-wiry-and-wzbr/

I think that these were covered before, but they are intriguing. Hmmmmmmmmm... I wonder how were they'd work for the 160M band?

Huh? / Radio World Letter: AM Ain’t Done Yet! And then, Ford. Plus, more AM gripes?

« on: January 25, 2023, 0743 UTC »

https://www.radioworld.com/columns-and-views/readers-forum/letter-am-aint-done-yet    Still, the amount of noise on the MW band just sucks.
And then, there's this:   https://www.radioworld.com/columns-and-views/guest-commentaries/did-am-radio-just-get-hit-by-lightning

Hey Pigmeat! Don't forget the Ford Feista, a.k.a. their answer to the Dodge Horizon, or the Chevy Chevette, (Or as we called it, the Shove-It!).

More AM Gripes ripped and linked from SWL'ing:  https://www.radioworld.com/columns-and-views/guest-commentaries/who-benefits-by-removing-am-from-cars

Speaking of Ford... More of this:  https://www.techspot.com/news/97807-ford-dropping-radio-2024-mustang.html

Part 15 AM and FM Station Operation / 49MHz Part 15 re-re-visited? Still usable, today.

« on: January 09, 2023, 1956 UTC »

Boomer FWR me this:   http://kdxradio.com/gallery_files/Brownwood_Bulletin_Fri__Nov_18__1977_hobbyist.pdf A 1978 article on 49MHz Part 15 band. And then, this VID: https://www.youtube.com/watch?v=sPf6_v21xds     WOW!!!! Does all this bring back memories of 49MHz stories of, walkie-talkies, cordless phones, and baby monitors. Certainly, made it worth having a scanner, with a good VHF Low antenna, in the 1980´s. (Hi-hi...) Still, this band could be great to use, now. Like this dude did:  http://www.fordyce.org/scanning/scanning_info/babymon.htm      Years ago, I´ve audio modified a Safety dual-channel 49MHz Baby Monitor, 49.850MHz and 49.870MHz, NBFM. I went a step further by adding a POT for audio adjustment and an extra resistor, in series. (Like 10k-Ohm, or higher.) And??? As a bonus, this Baby Monitor´s transmitter came with a built-in audio ALC unit that was really effective. Audio wise??? A little better than telephone-like, really. Then again, if you are going to use scanner radios to receive this, hi-fi audio quality isn´t a concern.

Amateur Radio / January VHF / UHF Sweepsteaks, then Winter Field Day 2023!

« on: January 08, 2023, 1906 UTC »

Uh-huh... Tis that time for this one:  http://www.arrl.org/january-vhf    Lack of foliage helps out on 2M, on up, to get out. And, maybe 6M F2 this year. Then, the following week:   https://www.winterfieldday.com/    Now, the question is whether those Southern T-storms will settle down by then, and not rip-up the lower HF bands with crashes at night. And then, AM Rally:   http://www.amrally.com/

10/11 meters / Rare, late night 11M Sporadic ¨E¨ pipeline from Texas!

« on: December 30, 2022, 2058 UTC »

Wow!!! 27MHz CB was hoping, especially CH38LSB, from midnight to 2:30AM, (0500UTC - 0730UTC, 12/30/2022), with a direct pipeline to Texas. On 10M??? Just a beacon, or two, but no operating stations. All, on 11M. So, was 6M open last night?
