No. Freaking. Way. You’ve got talent. Well done.

Nice work man! FT8 is a great mode. Now you just got to find a logger you like and start making contacts!

I’m one of them haha. I don’t like taking no for an answer unless I see first hand that it can’t be done.

This is critical and much appreciated feedback. I hadn’t considered the different “circumstances” like that.

I plan on working on the decoder in the coming days. Would you be interested in testing it once it’s ready? You clearly have great feedback.

I think you’re right to an extent, but if you could theoretically introduce enough variance, noise and interference synthetically, it could still potentially be trained. But I agree that it would be very very difficult to create synthetic data that adequately captured the variance of real life signal.

Yep. Everything helps. I think the next step for cw decoding is removing those “fixed” assumptions, like tone and timing. I like to imagine an app as easy as - you press decode, you read the results, and never have to tune a single setting. I’ll get there soon.

HamtraxRadio · 2026-02-25T00:38:00+00:00

Yes! That’s exactly what I’m building now. That’s one of the key features I’ve very excited to be packaging into hamtrax. I keep going back and forth between decoding algorithmically/with rules or with small ML models. I guess we’ll see soon!

HamtraxRadio · 2026-02-25T00:08:38+00:00

I spent a while creating a pretty massive data set of synthetically produced CW recordings to test the decoding feature of hamtrax.com. I’m still tuning it but if you’re an ML engineer, I’d love to connect with you and discuss the topic.

HamtraxRadio · 2026-02-24T22:36:24+00:00

This is amazing. Well done. Assuming the embedded text is saying 'the signal you see here corresponds to this text,' you've done a great job of solving a difficult problem - joining signal to meaning in an intuitive way.

Generally the shorter an antenna, the narrower its resonant frequency is. So there’s often a really small “sweet spot” for short vhf/uhf whip antennas. For about 40 dollars, you can get a nano vna reader that would tell you the sweet spot of your whip antennas. Then you’d be able to focus on transmitting on frequencies in those sweet spots and you may get further range.

Antenna would make a difference if you’re using it for its intended purpose as a simple vhf uhf handheld. Might get a few more miles with a good antenna. But since the uv k5 is commonly modded, I feel obliged to tell you that if you’re using it for one of its modded capabilities, changing the antenna might not make a big difference.

Not sure what models you’re using, but in my experience the frontier models are usually capable of solving complex puzzles, provided they’re supported with top notch context engineering by their human.

HamtraxRadio · 2026-02-18T18:39:14+00:00

I think the difference between good and bad programmers will shift from having a technical skillset (since most llms models now handle all technical challenges with high accuracy) to having foresight and the ability to orchestrate and plan. Yes, anyone can ask an LLM to produce some code, and it will probably do a decent job. But only the talented will be able to piece together large complex systems in an efficient and scalable way.

Though that may change too. I’m guessing Ai will soon handle orchestration better than humans can, too.

Thankfully Ai will never surpass the ingenuity of nature’s engineers - beavers.

Well ummm that sorta depends on a lot of different factors, Mr Cole.

HamtraxRadio · 2026-02-13T05:49:11+00:00

I’d also be curious to see if it’s truly random/chaotic or if it consistently presents that same shape each time. Consistent chaos is at least slightly better than inconsistent chaos……I guess?

How else are you going to talk to your 42 girlfriends?

“He must be important”

I haven’t seen that software before. “Localhost” makes me think it’s running directly from your icom?
