Sad thing is there is no way to securely communicate via ham radio.

But I'd be fully open to going pirate!

And with regard to unlocked bootloaders, I think it's the manufactures wanting to lock away choice and options that is the issue more than the government.

Yeah, is a Pico... $5

This is already happening with smart phones.

Here I am on my phone. I do not desire this format. And nothing you have posted suggests that anyone wants this format.

All it shows is device, not preference.

Anytime something is recorded wide screen my wish is that it remains in that format, regardless of platform I am on.

If I'm on my phone it takes less than half a second to rotate my screen and view as intended, on my desktop I can't do that.

Also in this case quite a bit of the original was lost, seeing the YouTube version is much better.

Still using the buds I got with my galaxy S4. They've outlasted 4 sets of BT buds.

LoL... Really?

1 number apart, but considerably different. Sure.

Difference between x5 and x7 maybe. To pass x6 a device must be submerged to a depth of 1m for 30 minutes.

IPx7 is for a device intended to operate permanently submerged. So not a phone.

That fact your picking the difference shows you don't know the difference.

IP67 is just a marketing gimmick. I'd be impressed if a phone with this rating would endure 12 months submerged and still function. Who needs this anyway?

Galaxy S5 was IP67 with a headphone socket, removable battery and dedicated microSD card slot. Others have also existed. Taking like adding a headphone socket costs more than 5 cents is stupid.

I'm a Bluetooth buds convert now, but I'd still like the choice.

Have had this issue myself asking with other DD card related issues.

I can't understand why the pi foundation persist with using SD as the only physically practical storage option.

They're looking post the point of needing a way to snap on reliable EMMC storage, as a default, in a way that doesn't leave a cable or something permanently plugged into a USB port.

Sure, USB is a fine option, but I hate that it's only an option and not a designed default.

Most of us only need 8GB or so for the OS, 8GB or good quality durable EMMC should hardly cost anything.

Other tiny computers and even economy notebooks and Chromebooks already use this.

So you'd need 10,000 of them to generate 1 watt.

Sounds useless.

Don't know why I could not see this repply until today. It's been ascertained that chirp is not in the repo for Raspian Linux, so indeed that option never worked.

Nothing exciting here, just putting my TinySA and attenuators through their paces. Seems pretty unexciting.

0% and 1% power level measurements are probably the same and the minor deviation is just noise?

One of the attenuators is 30db/100W/DC-6GHz, the other is a push button unit, 0-60db/5W/DC-6GHz. They tested to be fairly linear.

About all that pops out is that RF power does sag a little on 2M and 70cm at 100% power setting leaving us with 9.12watts on 2M and 7.6watts on 70cm.

Searched the manual for this and came up empty. I think most of us know it's for data modes, but what exactly does it do?

I'm playing with FreeDV currently and in addition to running 14.236 USB-D i also have the Noise blanker, Notch filter and Noise reduction disabled.

I'm kinda wondering what the point of the -D mode is. Also I've had a look at the preset menu to see what functionality it brings. Potentially a few hand things there like ability to set different addresses, baud rates etc..

But neither -D mode or the presets disable the NB, NF or NR, thus when switching between voice and data modes these always have to be toggled... Leaving me wondering the point of -D is or the point of the presets?

Unless I'm missing something the vast majority of the digital modes prefer the most direct audio with minimal molestation (blankers, filters etc).

Have i got a point here or am i missing something? What does the -D mode do?

While typing the title i found some existing posts, but they don't really answer the question as well as I'd like.

The typical recommendation is to use some external web page that is not actually a lemmy instance.

This means if I'm using lemmy from within an app I have to pop into a web browser, find what I'm after copy anything needed to clipboard and pop back into the app ready to paste / re-format / search.

This sounds really not streamlined.

Other solution is to have a couple of accounts and flip between them and search each home instance for what I'm after.

I'm not sure I'm clear on what I'm asking so i'll give an example...

I'm on lemmy.world, there is a community on lemmy.radio/c/amateur_radio Let's assume i don't know this however.

a) How would i find this while logged into the lemmy.world website? b) How would i find this while logged into the lemmy.world via an app?

If this functionality does not exist that's fine, but all I've heard about federation makes me think it does exist and i haven't found it or don't understand it (hence why i think I'm asking a dumb question).

Is there a foolproof legitimate way to browse or search a list of communities on another instance without going to that instance or using a third party site?
