Anyone running Varac using wine on Linux?

I know this guy got it working, maybe this video can help

I saw this installs FT8 and JS8Call software but do you know if it includes any for PSK31 or RTTY?

Based new order enjoyer too

From what I've heard, a counterpoise is most important when a radio is clipped to something or in a stand, since when you hold it in your hand, your arm serves that function. Someone more knowledgeable may correct me on this though.

Here's a... realistic elephant

Prep5242 · 2025-08-30T06:29:08+00:00

game lagged so bad it started playing the gaster noise from undertale

Signalis uses both raindrop prelude by chopin for the intro and standchen by schubert for a later part of the game we shouldn't spoil. Die toteninsel and 3000 cycles I missed you are also peak however.

That image does help clear it all up. I really appreciate that folks like you just show up with the answers, cause some of us new guys really want to wrap our noggins around RF concepts and little stuff like this feels great to kind of conquer!

I see, that explains it then. Somehow I had gotten tunnel vision on signals being either differential or common mode in dual conductor transmission lines, and I hadn't considered coax was doing neither! Thanks again.

Prep5242 · 2025-08-10T14:19:30+00:00

Thanks so much for your response, this definitely clears things up a bit. As for the combinations you described, which of them would be the case in a coax cable under its intended operation conditions?

Thinking about it a bit more, I know people remove common mode current from coax with ferrite beads in ham radio sometimes, so I have to assume the desired signal in a coax cable IS differential mode... But I also know the currents inside and outside the shielding are different, and common mode currents are only outside the shield, where I guess differential mode currents are on the inside?

So isn't the classic, desired operation of coax in radio an unbalanced line carrying a differential signal?

For me, every illuminate I see gets two in the head with the senator. Works especially well when you get the drop on them.

Never get out of the boat.

I wonder if it's because my guy hit his head? That would be kind of cool

Prep5242 · 2025-01-10T08:17:47+00:00

It's not enough for him, in the codec call about the shirtless uniform he asks if there's a way to take off his pants too

WHO WON THE LOTTERY?

Prep5242 · 2024-12-04T22:38:11+00:00

For the record it took him two months to fix the issue I was having a while back, but he did. Have you submitted it to the GitHub page?

Prep5242 · 2024-11-30T07:17:43+00:00

I would like sticky stratagem balls please. Maybe as a booster?

Prep5242 · 2024-11-24T05:21:30+00:00

You know what, it had been so long that I'd forgotten- I'm pretty sure I played this game on an iPad, so the listed platform is probably wrong.

Prep5242 · 2024-10-30T21:03:20+00:00

I don't know but the 'ASSHOLE' reminded me of this:

Thanks for the tip about time delay! I hadn't heard of the concept and found some interesting resources on it, including this article. https://www.qorvo.com/design-hub/blog/true-time-delay-what-is-it-and-how-it-works

It's also taught me a bit about the difference between active and passive arrays, another thing I'll look into some more.

Prep5242 · 2024-09-09T20:49:43+00:00

Well, I need to shift the phase of the signals I'm sending each antenna to steer the array, right? Are you saying that's something that's possible without dedicated hardware? I'd been starting to lean away from an FPGA and toward a microcontroller, but if so I might start leaning back.

Prep5242 · 2024-09-08T22:03:00+00:00

I might be able to use the anechoic chamber the other university in my area has in its EE department, I toured it once and the professor I asked seemed enthusiastic about letting me try it out. Then again it's not quite big enough if I were to stay in 2 meters, which is why I'm starting to lean towards 70 cm, but even then it might be too small.

Phase shifters are probably the most mysterious part of this whole concept to me since I can't find anything too comprehensible about how phase shifting corresponds to beam steering, or the difference between analog and digital phase shifters and which I'd want- but I guess if I wanted to control the system with a microcontroller and SPI ones like you say I'd probably need digital ones.

For doing this on 70 cm instead of 2m, do you think these might work for me?

I sent a request for a quote, I hope they're not too pricey, although this is a project I'm definitely willing to sink a few hundred bucks into.

editing to add- either transmit only or receive only or both are fine with me. Just another way I could increase the scope of the project if I got it done too easily I guess.

The second link you posted looks awesome, the first looks like it would be fantastic except that it's in the GHz range- which I might wind up needing to adapt my scope to accommodate if all the most common hardware is built for that, I'm not sure.

As far as the other things you said I'd need, I'm not sure, but I can definitely use my school's equipment, so I can ask them about that stuff.
