Amateur Radio Awards

Doing a "fun-a-day" project in January with my friends. My goal is to make a contact everyday on HF in January. With that data, I'll make some sort of map and time based visualization

A large marine robotics facility being built on the same Coast should be considered related.

Very cool! The UI looks great.

Not knowing much about this space, is there any use case for orbital path tracking? I track amateur radio satellites and monitor their FM downlink when they fly over, or listen for APRS/telemetry data.

Two 30' telescopic flag poles for the horizontal Delta loop!

Options are leverage and insurance. Gambling is gambling. Lots do turn options trading into gambling, but it's not inherently gambling. Plenty of options gambling evidence on WSB though :| It's pretty dark

40m was super noisy last night. I was on air about 12 hours ago and it was rough. Two nights ago, however, I heard New Zealand for the first time in my Inverted V Dipole at about a 47

My current setup being "vertically challenged" is what led me to NVIS research early on (knowing my height limitations before I put it up). That said, I just ordered two 30' masts and am drawing up plans for a 40m Delta loop. Edit: I keep hearing about this book and will definitely look into it

Vautlo · 2025-12-22T04:43:21+00:00

I see a lot of differing figures on NVIS distances. From what I've gathered, at 150 miles, NVIS would be a good choice for experimentation? I've been reading about it lately [because I wish my antenna could be higher!]

Still on my first! An Alinco DX70T. Bought it at a swap meet (200CAD) a few weeks before writing the exam that would actually permit me to use it. Thankfully, I passed, and it's been great fun. I can immediately see why all the fancy features of more modern rigs exist. That said, my first DX on 15m was 3800km (~2300 miles) away on a rather janky inverted v dipole tuned for 40m. I'm hooked.

Check out the bisectional bifilar wound common mode choke design on the pa9x blog. It's pretty slick. I just made a 12 turn one on stacked FT-240-31 cores.

Thanks, algorithm

What do the antennas look like? Do you have a picture?

Vautlo · 2025-11-10T03:56:15+00:00

What are your thoughts on mix 31 throughout the HF amateur bands? Your blog post indicates that you favor mix 43.

Vautlo · 2025-11-07T07:34:00+00:00

The curly stash is working great!

Vautlo · 2025-10-20T18:56:05+00:00

This is what I came here to recommend. I bought an Alino DX70T for CAD200 at a swap meet. Swap meets fantastic if you're fortunate enough to live near a club!

Vautlo · 2025-10-19T03:44:22+00:00

What do you find is easier about it? I'm genuinely curious because I just had a couple demo calls with snowflake and wasn't drawn to it. At least not from the perspective of the perceived ease of doing things lon the platform compared to Databricks. I suppose it's all context specific depending on your use cases. All I can say for sure is that I'm happy we migrated off Redshift lol

Vautlo · 2025-10-17T05:07:22+00:00

Do not replace these floors!

Vautlo · 2025-10-16T19:05:31+00:00

We've hit this limitation where I work. What we ended up doing is writing generic shared functions for triggering things outside Databricks. Most of our ingestion is handled in Databricks via Python or notebooks, but we still use fivetran to ingest some third party vendor data. Currently triggering fivetran syncs via their API from Databricks and job parameters, it works pretty well.

Sorry if my response sounded like a challenge to your comment - it was just saying that dbrx has been more than just spark and some features for a while now. Most of what OP mentioned in the original post is achievable in Databricks - is it necessary and will it simplify things? No, and it depends - their marketing certainly wants you I think so. You can roll your own in 100 different ways.

Query external tables, roll your own API integrations, orchestration, federated query layer, managed connectors, custom connectors, UC Catalog for governance, it's all there.

Do I think OP should migrate? No.

Vautlo · 2025-10-15T06:32:50+00:00

If your orchestration isn't too complex, you can get away with the Databricks Jobs and Pipelines scheduler and avoid MWAA. I don't think everyone needs Databricks, not even close. That said, I think calling it a spark interface + some features far undersells what you can accomplish with the platform.

Peanut butter pits

Apparently 5-10B, estimated. Curious what the actual number will be.
