Hey everyone!

Just wanted to let everyone know we had a downtime of about 10 hours today. Around 8:00am EST, we maxed out our storage on this lemmy instance. I did get an alert for this, but there wasn't much I could do as I was out of town visiting family for Thanksgiving.

I am very sorry for this. I should have paid closer attention to sizing on our instance. It has been slowly growing over the months and it just sprang up. Again, apologies.

To fix this and hopefully solve any issues down the road, I have moved us to a new server with double the storage, double the CPUs, and double the memory.

This did change our IP address. I have done as much as I can to invalidate and flush caches, and I think we're good to go now. If you do see issues with images not showing, you may need to hard refresh the page and flush your local DNS.

If you have any questions or it seems like the instance isn't working correctly, please reach out to me.

Thank you!

Ben

This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%. Special thanks to @phiresky for their work on DB optimizations.

Wow they weren't kidding. DB size shrank by quite a bit. Curious to see what this does with our CPU usage. Also want to see if our federated instances dropped. QUITE a few instances have either de-federated or have stopped functioning lately.

As always, please let me know if you notice any issues, bad OR good!

This was an emergency update due to a XSS vulnerability with custom emoji. Lemmy.Radio does not have any custom emoji so there shouldn't have been any issue if you have used it the past day.

I’ve only contested during field day with my local club. Is the suggestion making a community here and using it to submit to contests? (If yea, then that sounds amazingly cool and I’m down, just not sure how it works)

Still works for me

And I love that but I need to be more cognizant of it. I’ll upgrade us to 0.18.1 soon and that brings some other changes.

Honestly had no idea posting to mastodon would post here as well

Yeah this is pretty awesome. I’ve built some EFHWs but yagis have always kinda made me nervous for some reason. Great build!

If the bigger instance has to push/pull in data from you personal communities because they sub to it, then yes. 1 person not using your front end isn’t going to change much.

it was me... i said that :)

"Allowed Hosts" is white listing btw. You should leave it blank if you want more than just lemmy.world and lemmy.ml

And I wouldn't say it reduces the load on those sites. It would kind of add to them in a way if you post from your instance or sub from your instance solo. If it's just you on your instance, it's barely a blip. May save them some photo hosting if you post.

SOME of the out of sync upvotes/comments are fixed in 0.18.1

I believe some things are populated by your hostname in the lemmy configs so straight IP may break a few things.

There’s a few things listed here to do: https://www.kb6nu.com/will-we-lose-the-2m-band/

and

Also this is the agenda for the meeting. Skimmed it but didn’t see which one pertains to this issue https://www.itu.int/wrc-23/wrc-23-agenda/

Active member but I can’t check the results. I always have issues with the ARRL website tho lol

The solar flare was categorized as an X1.08-class flare, making it one of the most powerful classes of flare to be ejected from the sun.

1: What is the implication on radiation/reception pattern of ground plane radials above horizontal?

The angle has an affect on the impedance. So if it was angled up 45*, you'd be "shortening" your antenna.

2: Does SWR being lowest with “inverted” radials indicate that the radials are too long?

A guess at this would be that if you're getting fair SWR with your radials at 45* above the plain, then your antenna is too long.

3: Is ground plane radial length measured from the attachment point...

Yes, the attachment point or "feed point"

Antenna's are black magic :)

If you're wanting to really find out where things are being thrown: trim the correct length for the 1/4 wave you're making then start with the desired angle (45* down is pretty standard for a 1/4 wave) for the radial but add a bit more length than your calculations show, then slowly trim down and test using your meter. Also when you're testing, make sure there's no other kind of interference above the radial plane. I've had that bite me in the ass.
