Iran’s new leadership ‘ready to talk’ following death of Ayatollah Khamenei. 3 #American service members have died. foxnews.com/video/63902287… #FoxNews

People were already getting fired for just posting while working or in their uniform. So can someone please tell me why they are now shocked because they are getting fired for celebrating a terrorist assassination? #WeAreCharlieKirk

@riprap1 Sometimes you just want to feel like you're at mission control or relive the days of running the reactor from the control room. 🤣

Why are ham radio operators obsessed with computer screens? Other than qrz (which you can have on your iPhone) I can’t see any reason to turn a radio room into what would look like an office/call centre 🤷🏻‍♂️

@Robbie_W1RCP @F4JSU Nice radio. I'd love the chance to play around with a KX2 to see how I like it for portable ops.

Out here doing what I love to do. Playing radio outside! #pota #hamRadio

@mwfoutch1 The flexibility can't be beat. Although for faster switching, I'd go with BNC connectors.

What do y'all think of this technique compared to switches?

@mwfoutch1 I like the content. Keep it up.

Opinions desired: For those of you who follow this channel, why do you follow it? What do you like or dislike about it? What would you like to see more or less of here? If there's little response, I will just keep doing what I'm doing. 73!

@NitekryDPaul I forgot to take final photos with everything cleaned up. It's all hooked up and running though. I also wrapped the top of the batteries with a few layers of kapton tape so no one gets shocked.

@K4ZMF Nice, making serious progress, I see it was 2 BMS, I was not sure with the setup I saw. I have never built from base cells before.

Solar inverter capacity doubled and batteries were built. Two 2P16S batteries with a combined capacity of 1260Ah @ 54V. Each battery has a JK BMS rated for 200A continuous load. #Solar #Battery #DIY

@EC4TR Yeah, it's quite the setup. The solar deployment I'm currently working on at my QTH isn't up to par with the in-laws setup.

@K4ZMF wow, that´s looks like a nuclear plant, I have 24 370w sp´s running into a 6kw inverter

@EC4TR The current array consists of 30 700W panels going into the first inverter. Plus there are 30 900W bi-facial panels soon to be deployed that will go into the 2nd inverter.

@K4ZMF how many solar panels for 36kw inverters?

@PappaCharlie2K Not at all. Cells are LiFePO4 with a good BMS. Cells can handle a discharge rate of 1C. Therefore, each pack can tolerate 630A draw. The BMS will only allow 200A, giving a huge safety factor. Nothing gets hot.

@K4ZMF Not afraid for a fire ?

@suyogvyawahare Check out EG4. They also make a 6000W unit if you don't need the full 18kW.

@K4ZMF I need this inverter for my village house 😬😬

@suyogvyawahare Believe me, I was shocked too. 40m EFHW 10-20' sloper with S0 noise floor. Antenna was also floor to the equipment only 40' away.

@K4ZMF Interesting!

@suyogvyawahare This is at my in-laws house. I do operate on HF while I'm staying there and the equipment along with 21kW of solar panels are surprisingly quiet.

@K4ZMF There will be noise in radio!!

I can't handle the names of some of these Chinese tech manufacturers...

@cqcqcqdx I knew my shack was missing something. Love the selection.

hey now 🍺

@KM6TWI 🤣🤣🤣

Are you threatening me?! You can take me but you cannot take my BAAAO-FENG!! I have spoken with the repeaters! They whisper to me in CTCSS tones! 😈

Today's fun project. Building 2 LiFePo packs for solar. 2P16S configuration. One pack arranged. Now to figure out the BMS.

I’ve been digging into ham radio’s future—reading, listening, even collaborating with AI to get our best guess. The big talkers, our “1 percenters,” keep saying we need to be more like gaming… but I haven’t heard solutions. Out in the open, though, is the World Radio League. Today, I joined. First impression? WRL looks like the future. The spot visuals alone—finally, something that isn’t an Excel spreadsheet. I’m especially curious about how N1MM+ Logger might integrate with WRL. They’re already pushing a contest-within-a-contest model, and it feels like the perfect bridge from Parks to Radiosport. I’ve got a learning curve ahead of me, but I’m not dropping dollars yet. For now, I’m impressed—both with the platform itself and its potential. As AI keeps evolving, so does the game. And I think WRL is one to watch. 73! -KA3DRR @WorldRadioLeag

@K4KHOMetroATL It looks like a really fun form factor for a radio to take hiking.

You don't know A radio until you have used it! The #XieguX6200 Is a fun Tranciever!!
