In many rigs, to make them sound loud & proud, instead of just cranking over the ALC POT's to 100% MOD, they'll just bypass, or rip-out, the ALC function, where the limits are the supply voltage fed to the rig itself and goes into Cut-Off. Yeah, most CB'ers, especially newer ones, don't care that they maybe putting out splatter from DC to light and harmonics that could be heard into the FM broadcast band, and worst, the AM Aviation Band. Ever set a scanner to CB CH19's 5th harmonic, 135.925MHz AM? It is interesting how many stations can be heard there, if you are near a busy 4-lane. In the 1980's, this was notorious.


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

I had to work through the weekend, so no contesting for me, even on the FM Simplex FREQ's. A couple of years ago, I did hear a Big-Gun VHF Contester from Maryland on 2M SSB off of my Discone. Not strong, but still heard him, from +200 miles away. And, that's being down in the bottom of this river valley. So, you just never know. I might have to bow-out of Winter Field Day next weekend, but it should be as much fun as Summer Field Day, and everyone worked is a point added.   

I´ve 1st seen this from SWL´ing, but a friend of mine FWR the direct link.   https://gcaptain.com/will-ssb-radio-return-to-the-us-naval-academy/

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.

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/

Amateur Radio / Re: 15 Meter AM? And, AM Rally for 2/2023?
« on: January 02, 2023, 1939 UTC »
Huh.. Speaking of AM, looks like the AM Rally is earlier this year, just after GHD:   http://www.amrally.com/  Hopefully, 20M, on up, will be rockin´ this year. Question is, can they ever get anyone to agree on a 2M AM FREQ? I haven´t heard anything about W1AW doing the event, yet. And, anyone got word on that Heavy Metal AM Rally. Those are fun, if you can catch when they are.   

Shows that we are finally getting serious about the Chinese and N. Korean activities, but it does make you wonder what HF FREQ´s will get ripped by this?

Equipment / Re: Best MWDX antenna? The tower itself.
« on: December 31, 2022, 1856 UTC »
Actually, one of the best MW antennas that I remember making was to shunt-feed the 50ft tower that I had at the time. In the middle of the day, the NYC Big-3, (AM660, 770, and 880.), all came in at S9 from 300 miles away. Extremely low noise, being a couple hundred feet from the nearest powerlines. Originally, I did that to get on 160M, 75M, and 40M. On TX, a manual MFJ-941D tuner tuned all that in, but my GND losses were bad for transmit. However, on RX´ing, it was quite good. https://www.qsl.net/w9rb/webdoc9.htm

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?


Well, after requests for this one, I´ve put it up there, the one from September 1992. I just can´t believe that´s over 30 years ago, now. Yeeeeeeeeeeesh....

https://www.gi.alaska.edu/news/haarp-bounce-signal-asteroid-nasa-experiment    I say, let HAM´s do it. Then, we can get credit for ultra rare DX. (Hi-hi...) At least, this helps them to focus upon not burning holes in the atmosphere, or trying to change the weather, so they can have at it. Huh... Looks like we need to bug them for what frequencies they are going to use.

UPDATE:    Ah... Hereś more details on date and FREQ´s.   https://swling.com/blog/2022/12/haarp-to-ping-passing-asteroid-with-shortwave-signals/

If Auroras don´t kill 10M propagation, maybe we can hear what this dude did.  https://swling.com/blog/2022/12/guest-post-10-meter-beacon-dxing/

The RF Workbench / Simple and better circuit for MiniWhip antennas?
« on: December 20, 2022, 1812 UTC »
Boomer FWR this to me. Looks easy enough, and if I was stuck as an apartment dweller, I´d build and try it. http://www.pa3fwm.nl/projects/miniwhip/
