@MCCCANM @MCCCANM Chaff can be fun for the electrical grid too.

Ok, here’s what you need to know about “Bombing Electrical Facilities”… Several countries, to include the U.S., use “Graphite Bombs”. These aren’t bombs in the sense you are thinking; they have a small explosive charge, but don’t destroy something by brute force. Instead, long graphite filaments are expelled. They extend across power lines & create a short-circuit. Either some form of protection cuts power to the line, or the line eventually fails. The graphite is vaporized in the process, leaving nothing behind. The effect is that the power goes out. These are sometimes called “Soft Bombs” & “Blackout Bombs”. We’ve used these before. They were used in Desert Storm, but unfortunately we used actual bombs later & did a lot of damage that couldn’t be repaired quickly. This is considered a mistake…the point is to disrupt electricity in a way it can be rapidly restored when hostilities cease, minimizing suffering of the civilian population. After all, without electricity, water & sewer systems stop working…which leads to public health issues. We used graphite bombs in Yugoslavia in 1999, turning off about 70% of the country’s electricity. They restored power in about 24 hours, though there were subsequent attacks. Anyway, if you have a good idea of the power grid, you can target parts of it while leaving others alone. For example, the part of the grid that feeds military facilities…though in practice, it will still probably affect some non-military stuff, unless the base is isolated. Hope that helps, seems like it’s going to be a topic of discussion.

@VE5REV Very cool when you print something and the dimensions are that spot on.

@KB7ZUT I originally planned to use glue but they fit like a glove and almost snap in. So I haven't used any glue this far.

I built a tri-band vertical antenna using my snazzy links. 15M, 17M & 20M. 3 bands totally resonant with tuned elevated linked radials. It's a POTA PERformer ripoff. Great option if you don't have a whip 😎

@VE5REV That doesn’t look right. Current in a half wave antenna is in phase across the length of the antenna. The diagram looks like it’s trying to say the two halves are out of phase, which would cause cancellation.

Has anyone seen this explanation of an EFHW before? Current source & return on the same wire. 🤔 De K6BP 42:30ff Vid: The Counterpoise - The Other Half of Your Antenna! youtube.com/watch?v=IYy5o9…

@ijustine @tim_cook Steve Jobs "are you getting it" 2007 introduction of the iPhone. Still gives me Goosebumps... youtu.be/MnrJzXM7a6o?si…

Got a chance to chat with @tim_cook about Apples 50th anniversary. What were some of your favorite Apple moments? Mine are MacBook Air envelope, colored iMacs, 1,000 songs in your pocket and of course the first iPhone ☺️

@ElectronicsbyJH @yashiro_ld @kuwahara82 @AnalogDevicesJP @by_kohei @0yama @edy555 @toragiCQ Thanks @ElectronicsbyJH so many good recommendations

Yes! I recommend: @yashiro_ld (Cool RF stuff, DIY MRI machine) @kuwahara82 (Cool RF Stuff) @AnalogDevicesJP (somehow better than the USA account 🤣) @by_kohei (Cool RF stuff and electronics in general) @0yama (DIY Audio Synth) @edy555 (NanoVNA dev) @toragiCQ (publisher)

@MM0OPX Nicely done 👏👏👏

It's alive.....easier that I thought. Just to fit the PCB into its enclosure and solder on the SO239's

@MehdiHacks Redacted drills! This is a fine state of affairs… I would guess German on the right.

I ordered both from Amazon DE. They have visual/surface finish differences. Here's another picture.

One of these drill bits is made in Germany, the other in China. Can you tell them apart? They're both Bosch SDS Plus long life.

@HB9VQQ Yikes 😬!

@KB7ZUT x.com/HB9VQQ/status/…

Today, starting at 1600z I will point my Spiderbeam to 3Y0K. Come along and try to hear live radio from Bouvet Island websdr.carrd.co try 14190 USB

@HB9VQQ I agree. My NM station however is struggling just to hear them. 73

@KB7ZUT Apart from the questionable stories in the run-up to the expedition, I think they are doing extremely well. 73

@HB9VQQ You can really see the strength of 3Y0K in the waterfall after Roland pointed the Spider Beam towards the island.

@KB7ZUT Done

@HB9VQQ Wow! That made a huge difference. 3Y0K signal came up ~10dB

@HB9VQQ Now I'm seeing some returns from 3Y0K. Nice to have a remote listening post in Switzerland...

@HB9VQQ I can decode all of the stations calling 3Y0K, but not hearing 3Y0K returning on 18.108. Nice setup, Roland.

Happy heavenly birthday to Canadian WW II veteran and Star Trek icon James Doohan. Known for playing Montgomery (Scotty) Scott in the original series, he also - on June 6, 1944 - stormed Juno Beach. He would have been 106 today. Learn more in my upcoming article with @CraigBaird!

@PeterVogel @K3TripleR @MakanoTakeko @DustinFinn @eschecter Having monitor envy. Must resist the urge to go to Costco and buy a pallet of new pixel providers. Nicely done.

Base station for aircraft/ship tracking, weather satellite signals decoding, amateur radio, especially WSPR, FT8, SSTV, APRS, satellite telemetry. Big screens feature HamClock for signals propagation and space weather conditions. @K3TripleR @MakanoTakeko @DustinFinn @eschecter @Mike_Coletta @BorgersonS

@Pytlicek I figured as much😬

@KB7ZUT 39dB? 🧐 too good to be true 🙄

Hopefully not a pirate. Let the chaos begin!!! #hamradio #3y0k

@ei2ip @HB9VQQ I had no clue until Roland posted about it. Maybe time to try something new.

@KB7ZUT @HB9VQQ I have QLog already just wasn't aware of the different versions

I have built my own Qlog Edition

@HB9VQQ Any plans for your fork? Looks like a interesting project
